The war on woke…energy?

by


I’ve been thinking a lot about language lately, and the strange way words that used to mean good things are now attacked as bad, and vice-versa. Diversity, equity and inclusion are radioactive. Mentioning environmental justice or climate change will get your federal program canceled. Coal is clean, even beautiful, and pointing out the connection to global warming makes you an alarmist, because speaking up when your government steers you towards disaster is now a bad thing to do. 

Recently I received an email excoriating “woke” energy policy, which seemed especially curious. I can see how awareness of historic racial injustice against Black people might nudge policy makers into greater support for renewable energy, given that pollution from fossil fuels tends to have a disparate impact on communities of color. But judging from the hostile tone of the email, I believe we may have different understandings of wokeness.  

Sometimes, though, words mean different things to different people without anyone realizing they aren’t using the same definition. That may be the case when Virginia leaders talk about the reliability of the electricity supply. Everyone agrees reliability is critical – but they may not be talking about the same thing.

Virginia’s need for power is growing at a terrific pace. Data centers consume so much electricity that our utilities can’t keep up, causing them to increase imports from out of state. That’s okay for now; West Virginia is not a hostile foreign nation. Also, Virginia is a member of a larger grid, the 13-state (plus D.C.) PJM Interconnection, which manages thousands of generating facilities to ensure output matches demand across the region. But even across this wider area, demand is increasing faster than supply, pushing up prices and threatening a shortfall. Unless we tell data centers to go elsewhere, we need more generation, and fast.

Democrats and Republicans are divided over how to increase the power supply. Democrats remain committed to the Virginia Clean Economy Act, which requires Virginia’s electricity to decarbonize by 2050. Meeting the VCEA’s milestones requires investments in renewable energy and storage, both to address climate change and to save ratepayers from the high costs of coal and fracked gas. 

Gov. Glenn Youngkin and members of his party counter that fossil fuels are tried-and-true, baseload sources of energy. They advocate abandoning the VCEA and building more gas plants, arguing that renewable energy just isn’t reliable. 

Note that these Republicans are not alarmists, so they ignore climate change. If they were the proverbial frog in a pot of water on the stove, they would consider it a point of pride that they boiled to death without acknowledging the reason.

Youngkin takes every chance he gets to slam the VCEA. As I’ve previously described, the governor sought to amend various energy-related legislation to become VCEA repeal bills, regardless of the original subject matter or how much good it could do.

Last month, Youngkin’s Director of the Department of Energy sent a report on performance-based utility regulation to the State Corporation Commission. With it was a cover letter that had nothing to say about performance-based regulation, but a lot to say about the big, bad VCEA. The letter insists that “By all models, VCEA is unable to meet Virginia’s growing energy demand” and urges the SCC to “prioritize ratepayer affordability and grid reliability over long-term VCEA compliance.” 

Unfortunately for the Youngkin administration, affordability hasn’t been an argument in favor of fossil fuels for many years now. A new solar farm generates a megawatt of electricity more cheaply than a new fossil gas plant, and that will still be true even if Congress revokes renewable energy subsidies – though doing so will make electricity less affordable. 

The argument from fossil fuel defenders then becomes that the cheapest megawatt is not a reliable megawatt. And that’s where meaning matters.

Reliability is so important that even the decarbonization mandate of the VCEA contains an important exception: a utility can build fossil fuel generation under certain circumstances, if it is the only way to keep the lights on. 

Dominion Energy is relying on this escape clause as it seeks regulatory approval to build new fossil gas combustion turbines on the site of an old coal plant in Chesterfield. The move is opposed by local residents, environmental justice advocates and climate activists. (No word on whether they are alarmists or simply alarmed.) They argue Dominion hasn’t met the conditions set out in the VCEA to trigger the escape clause, including achieving energy efficiency targets and proving it can’t meet its needs with renewable energy, energy storage and demand response programs.

Virginia Republicans not only side with Dominion on this, they increasingly favor building gas plants over renewables as a general matter, urging the reliability point. It’s an argument that never made much sense for me, given that renewables make up only 5% of PJM’s electricity. That’s way less than the national average of over 21%, and other grids aren’t crashing right and left. 

The light bulb went off for me while I was watching the May meeting of the Commission on Electric Utility Regulation. A PJM representative showed a chart of how the grid operator assigns numbers to different resources according to how they contribute to the electricity supply. Nuclear plants get the highest score because they run constantly, intermittent wind and solar sources get lower scores, with fossil fuel plants in the middle. PJM calls that a reliability score.

For some Republicans, that’s a slam-dunk: the chart proves renewable energy is unreliable. But in spite of its label, the chart doesn’t actually measure reliability; it gives points for availability, which is not the same thing. 

As I once heard a solar installer testify, few things are as reliable as the sun rising every morning (or rather, the earth rotating). With modern weather forecasting, grid operators can predict with great precision how much electricity from solar they can count on at any given time from solar facilities arrayed across the region. Solar energy is highly reliable, even though it is not always available. Add storage, and the availability issue is also resolved.

Obviously, the grid would not be reliable if solar were the only resource operators had to work with. But it isn’t. PJM calls on a mix of different sources, plus storage facilities and demand response, to ensure generation precisely matches the peaks and valleys of demand. Reliability is a matter of keeping resources in sync and ensuring a robust transmission and distribution system.

The threat to reliability today comes from the mad rush to connect new data centers. PJM has been roundly criticized for not approving new generating and storage facilities’ connection to the grid at a fast enough pace to keep up with the increase in demand and retirements of old, money-losing fossil fuel plants. Scrambling to recover, recently it decided to prioritize a smaller number of big, new gas plants over the thousands of megawatts of renewable energy and storage still languishing on its waiting list. 

Meanwhile, PJM wants utilities to keep operating coal plants even though it will make electricity less affordable and violate state climate laws. In this it is joined by the Trump administration, which wants to require utilities to keep running coal plants explicitly to support the coal industry. 

Analysts say this is the wrong way to achieve reliability. A recent report from the consulting firm Synapse estimates that PJM’s approach will raise residential electricity bills by 60% by 2036-2040. By contrast, reforming its interconnection process and enabling more renewable energy and storage to come online would lower bills by 7%. By Synapse’s calculation, Virginia would see the most savings of any state. 

In other words, Virginia Republicans are pursuing reliability the wrong way. Instead of pressuring Democrats to back away from the VCEA, they ought to be pressuring PJM to reform its approach. Reliable power doesn’t have to be expensive, if you take the politics out of it.

Utility efforts to undermine rooftop solar meet stiff opposition from Virginia customers

by

Virginia’s investor-owned utilities thought 2025 would be the year they put an end to net metering – and with it, rooftop solar installers’ modest competition with their monopoly.. The 2020 Virginia Clean Economy Act (VCEA) removed many barriers that residents and businesses installing solar panels under the state’s net metering law had faced, but it also called for the State Corporation Commission to reevaluate the program, beginning right about now. 

 Not surprisingly, Dominion Energy and Appalachian Power are seizing this opportunity to push for changes that would undermine the economic calculus supporting customer-owned solar.  

Since at least 2007, Virginia law has required that customers of Dominion and APCo who have solar panels on their property be credited for surplus electricity they supply to the grid at the same retail rate they pay for electricity. The credit is applied against the cost of the electricity the customer draws from the grid at times when the panels aren’t generating, reducing what they owe on their electric bill. 

But now that they have the chance, both utilities have filed proposals to end net metering. Both essentially propose to charge new solar customers the full retail rate for the electricity they draw from the grid (with Dominion using a more complicated half-hour “netting”), but compensate them for electricity fed to the grid only at the utility’s “avoided cost,” or what it pays to buy electricity from other generators. By law, existing customers and new low-income customers with solar would be unaffected.

APCo calculates avoided cost as the wholesale cost of energy and capacity, plus transmission and ancillary services, for a total of less than 5 cents per kilowatt-hour. Thus, a homeowner with solar panels would now pay the full retail rate of about 17 cents/kWh for electricity drawn from the grid, while being credited at less than one-third that amount for electricity put back on the grid. 

Dominion’s approach instead pegs avoided cost to what it pays for solar generation and associated renewable energy certificates (RECs) bought from certain small producers under power purchase agreements, an average of about 9.5 cents/kWh. Dominion’s residential rate currently averages about 14 cents/kWh, but would go up to more than 16 cents if its latest rate increase request is granted.

The VCEA gave APCo the first swing at the piñata. APCo filed its proposal in September, and the SCC will hold an evidentiary hearing on May 20. Dominion only filed its petition last week, and no hearing date has been set yet. 

Not surprisingly, APCo’s proposal generated fierce opposition from advocates and solar installers. They point out that it’s hard enough to make the economics of home solar work with net metering at the retail rate; slashing the compensation for electricity returned to the grid by more than one-third, as Dominion proposes, or two-thirds, as APCo wants, would make solar a losing proposition for most homeowners. Maybe economies of scale and other factors would allow the market for commercial solar to survive under Dominion’s program, though Dominion’s insistence on confiscating customers’ RECs won’t make anyone happy.

If solar owners definitely lose under APCo’s plan, advocates say other ratepayers don’t necessarily win. A homeowner’s surplus generation travels only the short distance to the nearest neighbor, lessening the need for the utility to generate and transmit power to meet the neighbor’s demand. Since the utility charges that neighbor the regular retail rate for the electricity, without having to bring it from somewhere else, the utility saves on transmission costs. On top of that, the surplus solar comes in during the day, when demand is typically higher than at night and electricity is more costly, making solar more valuable to the utility. Plus, it is clean and renewable, and the customer bears all the cost and risk of the investment.

Utilities do not share this rosy view. By their way of thinking, solar customers use the grid as free energy storage and backup power, without paying their fair share of grid costs. Not only does this deprive the utility of revenue, but those grid costs now have to be spread out among the remaining customers. This, they say, creates a cost shift from solar owners to everyone else. 

More than a decade ago, Virginia took tentative steps towards resolving the dispute, with the Department of Environmental Quality setting up a stakeholder group to work towards a “value of solar” analysis. The process was never completed — the utilities walked away from the table when it appeared the results weren’t going to be what they wanted, and the group’s work product did not include numeric values or policy recommendations. 

Virginia is hardly alone in navigating these clashing narratives. 

Other states and regulators have arrived at very different conclusions as to the “correct” value of distributed solar to utilities, ratepayers, and society as a whole. States like Maryland kept net metering after a value of solar analysis concluded the benefits outweighed the costs. On the other hand, California famously ended its net metering program in 2022 when solar comprised almost 20% of electricity generated in the state and created a mid-day surplus without enough storage to absorb it; at the time, 45% of that solar was distributed. That same year, however, Florida Gov. Ron DeSantis vetoed an unpopular bill that would have phased out net metering in the state.

The experience of other states, combined with an abundance of research and analysis conducted over the years, gives the SCC a lot to work with as it considers the fate of net metering for APCo’s customers this year, and later for Dominion’s.

Countering the arguments of the utility’s hired witnesses, solar industry and environmental organizations have weighed in on the APCo docket with testimony from experts with nationwide experience. The experts pointed out a range of errors and omissions in the utility’s work product. They also presented their own benefit-cost analyses demonstrating a value for distributed solar in excess of the retail price of electricity, using tests often applied to energy efficiency and demand-response programs.

Perhaps even more significantly, SCC staff also filed an analysis that found many of the same problems with APCo’s proposal, including failures to comply with statutory requirements. The staff report did not include a quantitative analysis, but it urged the importance of considering benefits that APCo had ignored. Like the intervenors, staff recommended the commission reject APCo’s plan and retain its net metering program as it is, at least for now.  

Although the staff report would seem likely to carry weight with the commissioners, it’s never easy to predict what the SCC will do in any case before it. But in Virginia, unlike California, distributed solar makes up vanishingly little of total electric generation. Even taking the utilities’ arguments at face value, it seems foolish to upend this small but important market to remedy a perceived harm that is, at least for now, more theoretical than real.

Facing data center sprawl and an energy crisis, Virginia legislators leap into action. Nah, just kidding.

by

This was supposed to be the year the General Assembly did something about data centers. Two years ago, it crushed the first tentative efforts to regulate construction, choosing instead to goose the pace. Last year it again killed all attempts at regulation, punting in favor of a study by the Joint Legislative Audit and Review Commission (JLARC). 

JLARC’s report was released in December to a soundtrack of alarm bells ringing. Unconstrained data center growth is projected to triple electricity demand in Virginia over just the next 15 years, outstripping the state’s ability to build new generation and driving up utility bills for everyone. On top of the energy problem, the industry’s growth is taxing water supplies and spawning billions of dollars’ worth of transmission infrastructure projects needed to serve the industry.

Yet the most popular strategy for addressing the biggest energy crisis ever to face Virginia is to continue the status quo – that is to say, to keep the data center sprawl sprawling. Of the two dozen or so bills introduced this year that would put restrictions on growth, manage its consequences, or impose transparency requirements, barely a handful have survived to the session’s halfway point this week. 

The surviving initiatives address important aspects of local siting, ratepayer protection and energy, though they will face efforts to further weaken them in the second half of the session. Even if the strongest bills pass, though, they will not rein in the industry, provide comprehensive oversight or address serious resource adequacy problems. 

HB1601 from Del. Josh Thomas, D-Gainesville, is the most meaningful bill to address the siting of data centers. It requires site assessments for facilities over 100 MW to examine the sound profile of facilities near residential communities and schools. It also allows localities to require site assessments to examine effects on water and agricultural resources, parks, historic sites or forests. In addition, before approving a rezoning, special exception or special use permit, the locality must require the utility that is serving the facility to describe any new electric generating units, substations and transmission voltage that will be required. Existing sites that are seeking to expand by less than 100 MW are excluded. HB1601 passed the House 57-40, with several Republicans joining all Democrats in favor. 

SB1449 from Sen. Adam Ebbin, D-Alexandria, is similar to HB1601 but does not include the language on electricity and transmission lines. SB1449 passed the Senate 33-6. 

Typically, when the House and the Senate each pass similar but different bills, they each try to make the other chamber’s bill look like theirs, then work out the differences in a conference committee. If that happens here, the House will amend SB1449 to conform it to HB1601 before passing it. The Senate might amend the House bill to match its own. In this case, however, Ebbin’s bill never had the language on electricity and transmission. It’s possible the Senate will recognize that HB1601 is better and pass it as is rather than watering it down to match SB1449; otherwise, the bills will have to go to conference.

Only two ratepayer protection bills passed.  SB960 from Sen. Russet Perry, D-Leesburg, is the better of the two. It requires the SCC to determine if non-data center customers are subsidizing data centers or incurring costs for new infrastructure that is needed only because of data center demand; if so, the SCC is to take steps to eliminate or minimize the cross-subsidy. The bill incorporates a similar measure from Sen. Richard Stuart, R-Westmoreland. It passed the Senate by a healthy 26-13, but leaves the question of why those 13 Republicans voted against a bill designed to protect residential customers from higher rates. 

Over in the House, HB2084 from Del. Irene Shin, D-Herndon, started out similar to Perry’s bill but was weakened in committee to the point that its usefulness is questionable. It now merely requires the SCC to use its existing authority during a regular proceeding sometime in the next couple of years to determine whether Dominion and Appalachian Power are using reasonable customer classifications in setting rates, and if not, whether new classifications are reasonable. It passed the House 61-35. Hopefully the House will see the wisdom of adopting SB960 as the better bill, but again, these could end up going to conference.

The only data center legislation related to energy use to have made it this far is SB1047 from Sen. Danica Roem, D-Manassas. It requires utilities to implement demand-response programs for customers with a power demand of more than 25 MW, which could help relieve grid constraints. It passed the Senate 21-17.

The data center industry and its labor allies were successful in killing all other data center initiatives, including the only bills that dealt with the energy issues head-on. This included legislation that basically called on the industry to live up to its sustainability claims. SB1196, Sen. Creigh Deeds, D-Charlottesville and HB2578, Del. Rip Sullivan, D-Fairfax, would have conditioned state tax subsidies on data centers meeting conditions for energy efficiency, zero-carbon energy and cleaner back-up generators. Sullivan’s bill also set up pathways for data center developers to meet the energy requirements and work towards cleaner operations.

None of this mattered. Republicans were united in their determination not to put anything in the way of continued data center sprawl, and they were joined by a number of Democrats who were persuaded that requiring corporations to act responsibly threatens construction jobs. HB2578 died in subcommittee, with Democrats Charniele Herring and Alfonso Lopez joining Republicans in voting to table the bill. SB1196 was never even granted a committee hearing. 

Yet the idea of adding conditions to the tax subsidies is not dead. Senator Deeds put in a budget amendment to secure the efficiency requirements that had been in his bill. His amendment takes on a House budget amendment requested by Delegate Terry Kilgore, R-Gate City, that extends the tax subsidies out to 2050 from their current sunset date of 2035, with no new conditions whatsoever. 

It seems like a reasonable ask for the tech industry to meet some efficiency requirements in exchange for billions of dollars in subsidies and the raiding of Virginia’s water and energy supplies. Indeed, the industry could have had it worse. Senator Stuart had introduced a bill to end the tax subsidies Virginia provides to data centers altogether. Alas, like several other more ambitious bills intended to bring accountability to the data center industry, it failed to even get a hearing in committee.  

Now, maybe Virginia will get lucky – or unlucky, depending on how you look at it – and the data center boom will go bust. The flurry of excitement around China’s bid to provide artificial intelligence at a fraction of the cost of American tech joins other news items about efficiency breakthroughs that could mean the tech industry needs far fewer data centers, using far less energy and water. That would be good for the planet, not to mention Virginia ratepayers, but it would leave a lot of empty buildings, upend local budgets, and strand potentially billions of dollars in new generation and transmission infrastructure. A little preparation and contingency planning would seem to have been the wiser course.  

Failed bills.

Most bills to regulate data centers never made it out of committee, but the problems of data center sprawl and resource consumption will only increase in coming years. In addition to the energy legislation from Senator Deeds and Delegate Sullivan, here are other bills we may see come back again in another form. 

SB1448 from Sen. Richard Stuart, R-Westmoreland, would have required any new resource-intensive facility (defined as drawing more than 100 MW or requiring more than 500,000 gallons of water per day) to get a permit from the Department of Environmental Quality. DEQ is to permit the facility only “upon a finding that such facility will have no material adverse impact on the public health or environment.” The impacts are broadly defined and include transmission lines and cumulative impacts from multiple facilities in the same area. The bill reported from Senate Agriculture, Conservation and Natural Resources but was then sent to Finance and Appropriations, never to be heard from again. 

A bill from Del. Thomas would have required localities to change their zoning ordinances to designate data centers as industrial uses and to consider changes in how they evaluate data center siting, especially around noise impacts. HB2026 was tabled unanimously in subcommittee. 

HB2712 from Del. Ian Lovejoy, D-Manassas, would have authorized a locality that is weighing a permit application for a data center to consider factors like water use, noise and power usage, and to require the applicant to provide studies and other information. It lost on a bipartisan subcommittee vote. 

Lovejoy’s HB1984 would have required data centers to be located at least one-quarter mile from parks, schools and residential neighborhoods. It was killed on an 8-0 subcommittee vote. 

A third Lovejoy bill, HB2684, would have required Dominion to file a plan with the SCC every two years to address the risk that infrastructure built to serve data centers might become stranded assets that other customers would be left paying for. It was never docketed. 

A bill that did not mention data centers but originated with local fights over the siting of transmission lines needed to serve them was Roem’s SB1049. It would have prohibited new overhead transmission lines unless the SCC determined that putting them underground was not in the public interest. It lost in a 4-11 vote in committee.

Distributed solar bills move forward, while progress on siting utility solar stalls out

by
Photo credit Norfolk Solar.

Virginia’s desire to be a leader on clean energy has faced numerous challenges over the past few years, coming from many different directions. Landowners who want utility-scale solar on their rural property face increasingly hostile county boards, with no provisions for relief. 

School systems, local governments and commercial customers that want solar on their buildings have been blocked by expensive new interconnection requirements imposed by Dominion Energy. And the clock is ticking on net metering, the program that gives customers with solar panels a one-for-one credit on surplus electricity they feed back into the grid. 

The solar industry is used to struggling for every foothold it gets in Virginia, but these new challenges come at a particularly bad time. With data center growth creating huge pressures on our electricity supply, Virginia needs more clean energy in every size range, and needs it now. Any coherent approach to meeting demand has to include removing unnecessary barriers to both utility-scale and distributed solar. That both are facing more barriers, rather than less, suggests the state still hasn’t figured out what it takes to be an energy leader.  

None of the legislation at the General Assembly this year addresses this fundamental failing head-on, but several bills took on some of the barriers. In particular, bills focused on rooftop solar and other distributed generation have made it to halftime in decent shape.

Sadly, the same cannot be said of bills designed to bring more utility-scale solar to Virginia, including siting legislation developed by the Commission on Electric Utility Regulation (CEUR) and carried by Del. Rip Sullivan, D-Fairfax, and Sen. Creigh Deeds, D-Charlottesville. The legislation sought to tackle the biggest obstacle to unleashing gigawatts of clean, low-cost energy across Virginia: local governments that deny permits to solar and energy storage facilities, acceding to neighbors who don’t want to have to look at solar panels where they once saw fields and forests. (Anti-solar fossil fuel front groups don’t help matters either.)  

On the House side, Sullivan’s HB2126 was killed in a subcommittee vote. Senate Bill 1190 made it to the Senate Floor but was defeated when two Democrats, Senators Russet Perry and Lashrecse Aird, joined with all Republicans in siding with localities that did not want to cede any part of their authority over land use. The bill would have pressured local governments, but it did not strip them of authority. They would have been required to include in their comprehensive plans targets for energy production and energy efficiency (the latter an interesting addition). In evaluating specific projects, localities would have had to consider advisory opinions that would be issued by a new interagency panel of experts recruited from Virginia universities. Perhaps of greatest import, localities would no longer have been allowed to adopt ordinances that ban all projects outright or place unreasonable restrictions on them, or deny permits “without a reasonable basis.”

The Senate bill “incorporated” (by which is meant, it jettisoned the provisions of) another solar siting bill from Sen. Jeremy McPike, D-Woodbridge, and a separate piece of legislation from Sen. Schuyler VanValkenburg, D-Richmond, that would have prescribed rigorous best practices for utility solar projects.

Over in the House, however, a companion to VanValkenburg’s bill from Del. Candi Munyon King, D-Dumfries, HB2438, passed the chamber 48-46. The bill came from the solar industry itself, proposing to adopt the highest standards for itself. So why wasn’t the vote unanimous? Go figure.

Bills advancing small-scale solar move forward

Legislation promoting distributed generation did not go through the CEUR pipe, but these bills show some wear and tear of their own.  A loose-knit group of advocates under the banner of the Equitable Solar Alliance came in with a package of three bills, all of which remain alive after favorable committee votes. 

HB1883, from Del. Katrina Callsen, D-Charlottesville, increases the tiny carve-out for distributed solar that is part of Dominion’s obligation to buy renewable energy certificates in compliance with Virginia’s renewable portfolio standard. The bill has been pared down since it was introduced but still makes several changes benefiting behind-the-meter solar and battery storage systems under 3 MW.  The distributed generation carve-out, currently 1% of the renewable standard target, will get bumped to 3% in 2026 and 5% in 2028, with further changes possible later if the the State Corporation Commission (SCC) decides on it. Third-party power purchase agreements, which had been restricted to commercial projects, will now be available to residential customers. And whereas currently only projects smaller than 1 MW can earn up to $75 per renewable energy certificate, the bill now makes that amount available for projects up to 3 MW. (Certificates for larger solar projects are effectively capped at $45 per certificate.) 

Callsen’s bill also raises to 600 MW, from 200 MW currently, the target for solar on previously developed sites. It also specifies that 65% of distributed projects qualifying for the Virginia Clean Economy Act’s 1,100 MW target for solar under 3 MW should be developed by non-utility providers.  

HB1883 passed the House unanimously. Its Senate companion, SB1040from Valkenburg, made it through committee without Republican support but passed the Senate 26-14. 

Two other bills, HB2346 from Del. Phil Hernandez, D-Norfolk, and SB1100 from Sen. Ghazala Hashmi, D-Richmond, establish a pilot program for virtual power plants (VPPs), which aggregate customer solar and storage resources and demand response capabilities. In concept, a VPP allows a utility to pay customers to let it make use of these capabilities, enabling it to meet peak demand without having to increase generation. (If you are familiar with programs in which your utility pays you to let it cycle your air conditioner off for a few minutes at a time on hot summer days, you have the idea.) VPPs are becoming popular in other states as a way to subsidize customers’ investments in things like battery storage, while reducing utility costs and saving money for all ratepayers. 

The original hope for this legislation was ambitious: a vision of energy democracy that would reshape the way utilities interact with residential and commercial customers and make the most efficient use of new technologies like electric vehicle charging and smart appliances. The financial benefits to customers could even be enough to offset the costs of investments like home batteries, potentially offering a way for rooftop solar to remain affordable even if the SCC guts Virginia’s net metering program. 

But, this being Virginia, the legislation making its way through committee calls only for pilot programs that utilities design and largely control, although they will be voluntary for participants. After 2028, however, the SCC may create permanent programs. SB1100 passed the Senate 22-18. HB2346 passed the House 71-27.

The third bill in the package, HB2356 from Del. Candi Munyon King, establishes an apprenticeship program to help develop a clean energy workforce, and requires participants to be paid prevailing wages. This bill is more politically divisive than the first two, and it passed the House only on a party-line vote. A companion bill passed the Senate on a party-line vote as well. With Republicans unified in opposition, we are likely to see amendments or a veto from the governor. 

A couple of other bills seek to address the costs of interconnecting small-scale solar facilities, including those on schools and government buildings. After Dominion Energy changed its rules in late 2022, customers found the cost of connecting solar facilities to the distribution grid was suddenly so high as to make it impossible to pursue projects in the affected size range.

HB2266 from Del. Kathy Tran, D-Springfield, requires the SCC to approve upgrades to the distribution system that are needed to accommodate grid-connected solar — a safeguard designed to prevent the utility from larding on costs. The utility must then spread the costs across all projects that benefit from the expanded capacity. This strikes me as a pretty elegant solution to the interconnection muddle. HB2266 passed the House 57-41. 

 SB1058 from Sen. Adam Ebbin, D-Alexandria, originally would have simply exempted public schools from interconnection costs. It was amended to look like Tran’s bill and then passed the Senate 21-18.

Finally, a bill from Del. David Bulova, D-Fairfax, would allow local governments to include in their land development ordinances a requirement that certain non-residential applicants install solar on a portion of a parking lot. HB2037 passed the House on a 64-32 vote and will now go to the Senate Committee on Local Government.

It’s the fossil fuels, stupid

For low-cost electricity, Virginia needs renewable energy — not gas plants

Southwest Virginia leaders are up in arms over electricity rate hikes. It’s understandable: Appalachian Power, which serves residents in 34 counties, has raised rates by over 46% since July 2021, and its rates now rank among the state’s highest. Last March, it sought another increase that would have resulted in residents paying $10.22 more per month on average. Although the State Corporation Commission’s November ruling granted APCo a much smaller rate hike, customers are raising a ruckus about the high bills.

Complaints have reached such a fever pitch that Del. James Morefield, a Republican who represents parts of five southwest Virginia counties, filed legislation this month to cap the rates APCo can charge. Over in the Senate, another southwest Virginia Republican, Travis Hackworth, has launched a direct attack on APCo’s monopoly: His legislation would allow any residential customer of APCo whose monthly bill exceeds 125% of the statewide average to buy electricity from another provider.  

These bills might be more performative than serious. But in this case, legislators themselves are at least partly to blame. In 2023, another Southwest Virginia Republican, Israel O’Quinn, drove legislation that excused APCo from having to write integrated resource plans (IRPs) – those pesky documents that tell regulators how a utility plans to comply with state laws and meet the needs of customers at least cost. Both Hackworth and Morefield voted for the bill. 

In 2024, O’Quinn also championed legislation that allows APCo to charge customers for costs of developing a small modular nuclear reactor. Hackworth also supported this new burden on ratepayers, though Morefield did not.

This year, the Commission on Electric Utility Regulation is promoting legislation to reform the IRP process, including making APCo file plans again. That may help. Fundamentally, though, the primary reason APCo’s customers are paying so much is that the utility remains so dependent on fossil fuels. As of the date of its 2022 IRP, APCo relied on coal and fracked gas for 85% of its electricity. Prices for both fuels spiked so high in 2021 and 2022 that utilities were left with huge bills to pay. 

 In 2022, APCo told the SCC it had spent an extra $361 million over budget on gas and coal. Virginia law allows fuel costs to be passed through to customers, so the SCC couldn’t prevent bills from rising to cover the outlay. Instead, the SCC allowed the company to recover the excess fuel costs from its customers over two years by charging roughly $20 more per month to residents, spreading out the pain but also extending it. O’Quinn’s 2023 legislation let the company finance the costs, which meant customers pay interest on top of the fuel costs.

 APCo was not the only utility passing along high gas costs. Dominion Energy Virginia also got caught off guard and asked to spread its excess fuel costs out over three years, adding an average of $15 to residential customer bills. Dominion customers are not happy either. 

 Gas prices have since dropped, and the remarkably short memories of legislators have led them to think they will now stay low forever. Having learned precisely nothing, they also insist that the only way to ensure an adequate supply of reliable, low-cost energy to serve the data center boom is for Virginia to increase its reliance on gas instead of transitioning away from it.    

 The evidence does not support this fantasy. Contrary to Republican orthodoxy, new renewable energy is cheaper than new fossil fuel generation. That’s why in 2024, 94% of all new power capacity in the U.S. came from solar, batteries and wind energy. Fossil gas made up just 4% of new generating capacity. Yes, many states are now proposing to build new gas plants, so the trend could reverse, but that’s only because the rush of data centers and new manufacturing has made large users desperate for more energy at any cost. 

 It’s true that solar, Virginia’s least-cost resource, only produces electricity when the sun shines. But even adding battery storage to solar energy, allowing it to serve as baseload power or a peak power resource, still results in lower electricity costs than the gas combustion plants that are used to produce electricity at peak times. (In Virginia, Del. Rip Sullivan, D-Fairfax, has introduced legislation to expand storage targets for Dominion and APco, including for long-duration storage.)

 The era of low-cost renewable energy is fairly new, but it is already impacting utility bills across the country. Virginia used to boast of its low rates; now there are 22 states with lower residential electricity rates than Virginia. And of those, U.S. Energy Information data shows that all but five generate a higher percentage of their electricity from renewable energy. 

With data centers proliferating across Virginia unchecked, utility rates are under even more pressure now. The Joint Legislative and Audit Review Commission data center study, released last month, warns that ratepayer costs will inevitably rise under an “unrestrained growth” scenario that reflects current policy.

It’s too early to tell whether any of the many bills to protect residential ratepayers and put guardrails on data center development will pass. For now, the governor and many Republicans seem to prefer to use the crisis to crush the transition to renewable energy. As in past years, Republicans have introduced bills to repeal the Virginia Clean Economy Act or undermine it in various ways.

Making solar more difficult and expensive to build is also part of the strategy. The party that used to stand for individual liberty and personal property rights now instead champions local governments that deny farmers the ability to put solar on their land.

Talking up fossil fuels and dumping on solar may make for good politics with the folks in rural districts. That doesn’t mean it’s in their interests. If high utility bills are what really matter, legislators should be pushing renewable energy and storage, not expensive gas plants. 

This article appeared in the Virginia Mercury on January 20, 2025. Interestingly, today writers at two other publications, Cardinal News and Bacon’s Rebellion, took up one aspect of this topic that I only alluded to, the fact that Virginia “imports” more electricity than any other state. Virginia politicians have been exercised on this topic for as long as I’ve been writing, and it has always struck me as strange. It’s not like we need to worry about the political ramifications of a trade imbalance with Pennsylvania.

But as Duane Yancey noted, those electrons coming into Virginia from elsewhere in PJM do tend to be dirty. That’s especially the case for APCo, which operates coal plants in West Virginia and has been ordered by the West Virginia Public Utilities Commission to run those plants at a 69% capacity factor, regardless of the economics. I have not been able to find out anywhere the percentage of APCo’s generation that comes from coal as opposed to gas, but the West Virginia PUC order unquestionably means APCo’s Virginia customers are paying too much.

One other thing to note on the topic of imports: when I wrote that APCo’s resource mix is 85% fossil fuels, that did not mean the other 15% is renewable. In fact, most of the rest is purchased power, meaning mostly fossil fuels also.

By the way, readers may notice a few discrepancies among the articles, which is worth explaining. Both Yancey and James Bacon cite figures for Virginia electricity rates and how they compare to other states that are different from my numbers. The reason is that they are working from combined rates for residential, commercial and industrial, where I’m using residential only. Virginia’s combined rate compares more favorably to those of other states than does its residential rate because our commercial and industrial rates are lower.

Virginia’s low commercial rates have been a major draw for data centers. But if you’re a residential customer right now, maybe that’s pretty cold comfort.

The clean energy revolution will continue

by
Photo credit iid.com

Eight years ago last week, I wrote a column titled, “Why Trump won’t stop the clean energy revolution.” Calling global warming a hoax, businessman and reality TV star Donald J. Trump had just been elected with a promise to save coal jobs and pull the U.S. out of the Paris climate accord. 

Climate activists were deeply distraught then, as now. I wrote in 2016, “Reading the news Wednesday morning was like waking up from a nightmare to discover that there really is a guy coming after you with a meat cleaver.”

But as I also wrote, there is only so much damage a president can do when technology, popular opinion and – especially – economics don’t support his agenda. Trump couldn’t save the coal industry (though he tried). Instead, his administration oversaw a 24% decline in coal employment. And where coal supplied 30% of U.S. electricity in 2016, by the time Trump left office it had fallen to 20%. 

In the intervening years, Trump seems to have lost interest in coal mining, even as he continues to embrace fossil gas production. His enthusiasm for gas fracking fits with his drill-baby-drill approach to energy, but it was also intended to win over voters in Pennsylvania, a major producer of shale gas. Ironically, the gas industry insists on calling methane “clean” precisely because burning it emits less CO2 than coal. 

While coal was dying, wind and solar were well on their upswing when Trump took office in 2017, and they continued to advance through his first administration. By 2020, wind and solar had become the cheapest forms of new electric generation. Today, renewable energy supplies more than 21% of the nation’s electricity, while coal’s share has dropped further, to just 16%. Trump or no Trump, technological advances and a thirst for cleaner energy continue to drive new wind and solar generation.

Indeed, the offshore wind industry – famously reviled by Trump – wasted no time last week in congratulating its erstwhile foe on his victory and insisting, hilariously, that his election is a big win for the industry. The first Trump administration, they noted hopefully, “laid out the fundamental framework for our modern offshore wind industry.”

Well, okay. From their lips to Trump’s ears. Trump is hardly known for consistency, and it is not impossible to imagine him softening his position on an industry that is creating well-paying jobs for the blue-collar workers who make up a portion of his base. His Virginia acolyte, Republican Gov. Glenn Youngkin, boasts of overseeing the building of the nation’s largest offshore wind farm. Why shouldn’t Trump pivot? 

Early in the Republican primaries, one candidate opined that all the solar panels and batteries sold in the U.S. are made in China. That wasn’t actually true. For years one U.S. company, First Solar, has ranked among the world’s top ten solar panel manufacturers. Among the domestic manufacturers of both EVs and batteries, one of the largest is Tesla, whose CEO Elon Musk is now a Trump darling. It is going to be fascinating to find out whether Musk uses his influence to benefit the clean energy transition generally, or only himself. 

Yet the notion that China dominates solar and battery production is also not wrong. China is eating our lunch on clean energy. Chinese companies produce 80% of the world’s solar panels and more than half of its electric vehicles. Sadly, perhaps, these are not cheap imitations of superior American products. They are world-leading technology. 

Chinese dominance of the world market was a major reason that President Joe Biden’s signature climate law, the Inflation Reduction Act (IRA), put so much emphasis on supporting domestic manufacturing. Tariffs on Chinese goods, Trump’s preferred approach, help U.S. companies compete for American consumers, but they don’t support an export market when other countries produce better goods for less money. Even at home, critics note, tariffs mostly just raise prices.

Yet Trump has vowed to repeal the IRA, and given that Congress passed it without Republican support, there is certainly a danger that a Republican Congress will comply. On the other hand, observers note that 80% of the manufacturing tax credits have gone to red states, and this August, 18 House Republicans signed a letter to Speaker Mike Johnson asking to keep the credits. 

I don’t want to sound too optimistic. Wait, let me rephrase that: I don’t feel optimistic at all. We are facing headwinds today that weren’t around in 2016. At that time, gains in energy efficiency meant electricity demand was not increasing, in spite of a growing population. With wind and solar displacing coal, there was a clear pathway for CO2 emissions from the electric sector to continue falling. 

Today, however, the skyrocketing demand for electricity from data centers threatens the progress we’ve made on clean energy. It remains to be seen whether artificial intelligence will unleash efficiency gains and novel technologies that can put carbon reductions back on track. Right now, though, tech companies are so desperate for power that they will take it from wherever they can get it, and regardless of carbon content.  (I notice, though, that they still want it to be cheap and are happy to greenwash it to meet their sustainability goals). 

Perhaps the biggest change from eight years ago is simply that we are that much closer to reaching catastrophic climate tipping points. 2023 was the warmest year on record, and 2024 is on track to surpass it. The effects are evident in the number and costliness of severe weather and wildfires made worse by global warming. (Just ask insurance companies.) It is frustrating, to say the least, to contemplate losing the next four years to an administration that thinks climate change wouldn’t be an issue if we would just stop talking about it.  

Yet Americans of all political stripes continue to support renewable energy by wide margins. And apart from a small minority of vocal climate deniers, most Americans want the U.S. to take stronger action on climate. 

This election revealed deep fault lines among the American public, but one thing we all have in common is the faith that our ability to solve intractable problems is stronger even than our tendency to wish the problems away. 

That’s why, even in the face of such serious headwinds, the clean energy revolution will continue.

Once again, Dominion’s energy plan falls short. This time, the SCC isn’t having it.

by
Dominion Energy headquarters, Richmond, VA

On October 15, Dominion Energy Virginia filed its 2024 integrated resource plan (IRP), and just as in 2023, the company shows no inclination to meet the carbon-cutting requirements of the Virginia Clean Economy Act (VCEA). Blaming soaring load growth from data centers, Dominion models only scenarios with increasing amounts of fossil fuel generation to supplement its investments in renewable energy and nuclear. A scenario that would actually comply with the law is discussed only as something stakeholders asked for, then dismissed as “infeasible.”

Tellingly, the company notes casually that its own scenarios “evaluate the impacts of” the VCEA, as if the law were merely advisory, while the utility retained the final say. It’s kind of like a driver thoughtfully “evaluating the impact” of a speed limit – and then accelerating.

To be fair, this used to work for Dominion. The State Corporation Commission (SCC) has a long history of criticizing Dominion’s IRPs and ordering the company to do better next time, but never outright rejecting a plan. If traffic cops only ever gave out warnings, you would expect to see more scofflaws.

This year, though, the three-member SCC has two new commissioners, and already they have shown they intend to take their oversight role seriously. The commission didn’t even wait to see what Dominion would come up with before demanding improvements. On October 11, four days before Dominion submitted its IRP, the SCC issued an order instructing the utility to supplement its filing with additional work, to be submitted by November 15.

The task list includes modeling plans that meet the requirements of the VCEA, with at least one that incorporates data center load and one that doesn’t, as well as least-cost plans with and without data centers. In addition, the SCC wants Dominion to break down the costs of new transmission projects to identify the expenses that are primarily due to data center demand. 

The order tacitly acknowledges that the staggering growth of the data center industry in Virginia has upended utility planning. At the same time, the SCC is not giving Dominion a free pass, either on costs or on VCEA requirements. If Dominion believes it can only meet demand reliably by adding expensive gas peaker plants, it is going to have to prove it.

As I wrote a few weeks ago, the SCC plans to convene a technical conference in December to examine issues around serving data center load. Of paramount interest to the commission are the questions of how much it will cost to meet the burgeoning demand, and how to protect other consumers from rate increases for new generation and transmission infrastructure needed only because of one industry. 

The SCC is not alone in its concerns about Dominion’s cavalier approach to its IRP obligations. Last year, with a goal of improving utility oversight, the General Assembly revitalized its Commission on Electric Utility Regulation, which formerly served as a graveyard for utility reform bills. (CEUR used to be pronounced “sewer,” but commission members would dearly love it if you would now call it “the cure.”) 

In a September 16 memo, CEUR director Carrie Hearne recommended members consider a list of reforms that would, among other things, require Dominion to include in its IRP “a VCEA conforming scenario that does not assume to exercise an immediate exemption due to reliability concerns.” This scenario would have to incorporate the social cost of carbon, meet energy efficiency metrics (another area where Dominion has fallen short), plan for the retirement of fossil fuel plants targeted for closure in the VCEA, and assume an “unobstructed” buildout of renewable energy and storage (removing the artificial caps Dominion currently employs). 

In other words, CEUR would like Dominion to follow the law.

Ratepayer and environmental advocates have applauded the more muscular approach being taken by CEUR and the SCC. Dominion, however, has remained steadfastly oblivious to the hints flung at it from all sides.

The company remains unapologetic. In an op-ed, Dominion Energy Chairman Bob Blue insists the company is pursuing an “all of the above” strategy that will produce electricity that is “reliable, affordable and increasingly clean” – an assertion he repeats three times, as if saying it often enough makes it true. 

As the IRP puts it, however, “perceptions of affordability are subjective.” Analyzing its favored scenario using the methodology directed by the SCC, Dominion projects residential bills will rise over the next 15 years from an average of $142.77 today to $315.25 in 2039. 

Let’s be charitable, though. Maybe when Mr. Blue said the company was committed to affordable energy, he meant for data centers.

“Increasingly clean” is even more counter-factual. As reported in the Mercury, “The utility’s previous plan projection said about 95% of electricity generation would be pulled from renewable sources. Tuesday’s updated plan calls for about 80% of generation to be spurred by renewables.” And as with the 2023 IRP, Dominion plans to keep expensive and highly polluting coal plants operating beyond their previous retirement dates, putting the company even further away from “clean.”

Dominion’s 2023 IRP received considerable criticism for projecting a doubling of greenhouse gas emissions by 2048, a year when they should be at zero under the terms of the VCEA. Dominion appears to have learned a lesson from that public shaming, but not the right lesson. The 2024 plan shortens the emissions time frame to 5 years, cutting out reporting for the later years when the proposed new methane gas plants would be in service and spewing out CO2. Instead, the IRP brags about lowering “emissions intensity,” a success it can achieve without cutting carbon, just by selling more electricity.

So much for affordable and increasingly clean. As for reliable, burning more methane will only exacerbate the climate change and extreme weather that have been wreaking havoc on southeastern utilities’ ability to keep the lights on. The recent storms should be a wake-up call for utilities to ramp up renewables, including distributed solar generation and storage to serve communities, rather than building more centralized, carbon-intensive fossil fuel plants to power data centers.

But some companies, like some people, never learn. Finding itself deep in a hole, Dominion proposes to keep on digging.

Geothermal energy is having a moment. Could it power Virginia’s data centers?

by
National Renewable Energy Laboratory

Drill down far enough into the earth, and you will hit hot rocks. Energy companies have used this heat to generate carbon-free electricity for more than a century. It’s an elegant concept, but it worked only where pockets of heat lay close to the surface, accompanied by steam ready-made to turn turbines. Those limitations confined geothermal power plants to geologically active areas like Iceland, parts of Indonesia, and a few locations in the American West. As of 2023, geothermal energy made up less than half of 1% of U.S. electricity generation. 

Suddenly, that is changing. New technology derived from oil and gas fracking methods is allowing energy companies to drill deep into the earth in places far from geologic activity. Wells can reach miles beneath the surface before branching out horizontally and creating fissures in hard, hot rock. Water injected into the wells comes back to the surface as steam to generate electricity. The steam is recaptured and re-injected to take up heat again, in a virtuous cycle powered by the earth itself. 

The benefits

These “enhanced geothermal” systems can produce 24/7 baseload electricity or fill in around variable sources like wind and solar. They can even be used like batteries to store energy, including for long durations.   

Unlike drilling for fossil fuels, geothermal companies avoid the shale formations that hold hydrocarbons, instead targeting non-porous rock. And since the product is not fossil fuel but steam, the technology produces zero-carbon energy without toxic or radioactive waste. 

Freed from geographic limitations and using the same technology and workforce as the oil and gas industry, geothermal energy is ready to take off fast. The U.S. Department of Energy (DOE) sees it spreading across the country to provide as much as 125 gigawatts (GW) of electricity by 2050. A global estimate suggests the industry could eventually produce 4,600 GW of electricity at a cost of 50 euros (around $55) per megawatt-hour or less.

In 2022 DOE launched an “Earthshot Initiative” to reduce the cost of enhanced geothermal energy in the U.S. to $45 per megawatt-hour (MWh) by 2035. If successful, that would put it at or below the cost of any other new, dispatchable energy source. 

Is this technology the answer to the surging demand for electricity from data centers and artificial intelligence? And could it allow Virginia to keep adding data centers without blowing up its climate goals?

The challenges

We do have to keep in mind that not all silver bullets prove to be sterling. Small modular nuclear reactors (SMRs) are evidence that some highly-anticipated technologies don’t follow the rosy timelines and price projections their boosters promise. 

Unlike SMRs, though, enhanced geothermal systems have already achieved commercial deployment. After successfully demonstrating the technology with a 3.5 MW pilot facility,  Fervo Energy signed a contract last year with Google to provide electricity for its data centers from a 115-MW enhanced geothermal power plant in Nevada. Fervo will deliver the power to the local utility, NV Energy, which will then charge a slightly higher price to Google via a proposed new “clean transition tariff.” Fervo has also signed a deal for an even bigger project that will deliver 400 MW to California utilities. 

Using a different fracking-based technology it calls a “Geopressured Geothermal System,” Houston-based Sage Geosystems recently agreed to supply 150 MW of power for Meta’s data centers beginning in 2027. Sage says it can make electricity not just by extracting heat but also by using pressure, an add-on technology that allows it to offer energy storage independent of steam production. 

Both Fervo and Sage say their methods can be used almost anywhere, and both cite advantages over established energy sources. Like wind and solar, geothermal is renewable and carbon-free, but it isn’t dependent on weather. It also doesn’t require fuel sources like coal and gas that are highly polluting and sometimes unreliable in extreme weather. 

Finally, with a small physical footprint relative to the energy produced, geothermal facilities could be located in urban areas or next to data centers and other large customers without the need for major new transmission lines. 

But of course, the fact that geothermal technology can be used anywhere does not mean it can be deployed profitably everywhere, or at least not yet. A map compiled by the National Renewable Energy Laboratory shows the most ideal areas are still in the West, where hot rocks lie within a few kilometers of the Earth’s surface. In most of the eastern U.S., deeper wells would be needed to reach the same temperatures. For this reason, DOE sees the technology proving out in the West first before spreading east.

But favorability is not purely a function of geology, according to Ben Serrurier, manager of government affairs and policy at Fervo. I wanted to know how soon geothermal systems could start providing electricity to the world’s largest concentration of data centers, in Northern Virginia. He said the biggest impediment for the industry is not location, but the high cost of capital and the paucity of government support compared to SMRs, hydrogen, and other new technologies. 

In spite of these challenges, Serrurier predicted geothermal would be deployed in Virginia by the latter part of the 2030s, noting that his company is already ahead of DOE’s projected timeline for the technology’s maturation. Eastern data centers present an especially attractive market, he said, because demand is increasing so quickly, and utilities have limited options for carbon-free energy. 

Alas, observers of the data center industry know that while renewable energy is nice to have, cheap energy is even nicer. So I wanted to talk about cost.

Serrurier told me Fervo’s first project will deliver power to NV Energy at a price of $107 per MWh, and Google will pay slightly more than that to the utility. That is twice DOE’s target cost for 2035, yet it still puts the price below the U.S average of 13.1 cents per kilowatt-hour ($131 per MWh) for commercial customers, and competitive with the average Nevada commercial rate of 10.92 cents, according to Energy Information Agency data.

That price is, however, more than the 9.54 cents/kWh that the average commercial customer in Virginia pays for electricity derived primarily from fossil fuels. And Fervo’s price is for drilling in the West, not in the less favorable geology of the East.

But heck, anywhere in the country, 10.7 cents for zero-carbon baseload power — with no waste to be cleaned up and no added healthcare costs from pollution — still sounds compelling. Google may have chosen to be a first mover in order to show leadership and promote a new technology, but it is also locking in a solid deal.

Sage does not make its costs public, but Lance Cook, the company’s chief technical officer, told me their process is competitive with combined cycle gas plants when the cost of fossil gas is above $6 per thousand cubic feet. (According to the Energy Information Agency, the price of gas is currently below that level in most states, though gas prices are famously volatile.)  

An additional benefit, said Cook, is that a geothermal plant could be co-located with a data center, foregoing a grid connection and obviating the need for transmission lines. “We can turn electricity into data,” he told me. “It is much easier to connect data than to wait for a grid connection.” 

Both Cook and Serrurier are confident that geothermal will beat new nuclear  price-wise, which today sounds like a safe bet. Analysts warn that cost continues to be a significant issue for the nuclear industry. Current projections for the cost of electricity from SMRs start at $142/MWh. 

Cook noted that Sage’s technology can also provide long-duration energy storage that isn’t dependent on the heat of the earth. This approach can be used anywhere to turn solar and wind power into baseload energy. Sage’s website claims it can achieve this for less than the cost of batteries or pumped hydro.  

With all this promise, enhanced geothermal has been slow to catch the attention of Virginia utilities and policy-makers. The Virginia Code includes geothermal energy in its definition of renewable energy, but enhanced geothermal is not on the list of energy sources that qualify for the state’s renewable portfolio standard (RPS). 

The General Assembly did pass legislation this year from Senate Majority Leader Scott Surovell, D-Fairfax, to include a similarly-named, but quite different, kind of geothermal energy – geothermal heating and cooling systems, also known as ground-source heat pumps – in the RPS. Geothermal heat pumps use the near-constant temperature of the ground just a few feet under our feet to help heat and cool buildings, much as air-source heat pumps do but with greater efficiency. A working group under the auspices of the State Corporation Commission is currently trying to figure out how to award renewable energy certificates (RECs) for a technology that does not produce electricity. 

But drilling down two miles or more and generating electricity at the utility level is quite another thing. Making enhanced geothermal systems eligible for the RPS would be essential to putting the technology on an even footing with other renewables for use in Virginia.

In an email, Surovell told me, “I have read about the Google geothermal project and believe there is significant potential in Virginia.I understand it is different, but we need to do all we can to try to meet the demand for energy created by data centers without upsetting the carbon-free goals we set with the Virginia Clean Energy Act.” He added, “Geothermal also has the potential to create thousands of well-paying trade jobs in drilling and pipefitting in the Commonwealth.”   

I also contacted Dominion Energy Virginia to gauge the utility’s level of interest. Dominion is facing an enormous challenge to meet the explosion of demand from data centers. Its 2023 integrated resource plan (IRP) proposed building new gas plants as early as 2028 and an SMR in 2034, but no geothermal energy. The plan failed to meet the carbon-cutting requirements of Virginia law, so the company ought to see the need to up its game for its 2024 IRP, due in October. 

Dominion’s answer was not encouraging. Aaron Ruby, Dominion’s director of Virginia and offshore wind media, responded with an email that made reference to the working group for geothermal heat pump RECs.

 “We’re certainly looking at the potential for geothermal in Virginia. The SCC is leading a geothermal working group, and there are lots of knowledgeable experts taking a close look. Most of the potential in Virginia appears to be geothermal heat pumps, with maybe less potential for power generation. The process is ongoing, so still more to learn.”

Echoing Gov. Glenn Youngkin’s rhetoric on energy, he added, “As you know, we’re experiencing an unprecedented growth in power demand. Reliably serving that growth requires an ‘all of the above’ approach, including offshore wind, solar, battery storage, next generation nuclear and natural gas. Emerging technologies like clean hydrogen, longer-duration storage and geothermal could also play a role.”

It’s not a great sign that Dominion ranks geothermal dead last. The company seems quite content to keep adding data centers to its customer base with no plan to meet its climate commitments. 

Data center developers, on the other hand, could vote with their metaphorical feet. If Dominion will not bring geothermal technology to Virginia data centers, maybe the data centers will go to the geothermal technology. Some data center operators say they need to be in Virginia to be close to customers in the East, but the industry’s rapid spread into other states shows many have flexibility. So why should they face public opposition and rising electricity rates in Virginia when they can go to Utah, Nevada or Texas to access low-cost, zero-carbon energy delivered 24/7 from a source that might even be located onsite? 

Especially since, in so doing, they would provide the capital and demand required for enhanced geothermal to achieve DOE’s goals ahead of time, and hasten the day when Dominion presents an IRP with a real zero-carbon plan.

Amazon claims to power all its operations with renewable energy. Yes, and I’m the Queen of Sheba.

by
Greenpeace protesters at the site of Amazon’s HQ2 in Arlington, Virginia, in 2019 called out the company for failing to make progress towards its commitment to power the cloud with renewable energy. Since then, the company has actually increased its carbon emissions. Photo courtesy of Greenpeace.

When Amazon announced this month that it had achieved 100% renewable energy seven years ahead of schedule, that sounded like really good news for Virginia. Amazon owns more data centers here than anyone else, and data center energy demand is driving Dominion Energy Virginia’s plan to renege on its climate commitments, keep dirty coal plants online and build expensive new gas plants and transmission lines.  

Unfortunately, Amazon’s announcement is so full of asterisks it looks like a starry night. 

Let’s start with the good news. Amazon’s claim that it has purchased enough renewable energy to “match” its energy use is likely true, though its sustainability report doesn’t reveal essential details like how much energy the company uses. Amazon also says it is the largest corporate purchaser of renewable energy in the world, an impressive achievement. 

Some of that renewable energy is in Virginia, so it is reasonable to say it serves the company’s data centers here. A map on Amazon’s website shows the company has invested in 19 solar farms in Virginia, with a capacity that totals around 1,386 MW  – about a quarter of all solar installed in Virginiato date. That’s terrific. If every company operating in Virginia did as much, we’d be rolling in solar, figuratively speaking. 

So what am I complaining about? 

One problem is that the energy appetite of Amazon’s data centers in Virginia far outstrips the output of all of its solar farms here. The other problem is that producing renewable energy in the middle of the day can only very loosely be said to “match” energy used at other times of the day and night. Meeting energy demand on a 24/7 basis is harder, and Amazon isn’t even trying. 

Let’s start with the numbers. Because the sun doesn’t shine all the time, a large solar array produces, on average, 22-25% of what it produces on a cloudless day at noon. (That percentage is known as the facility’s capacity factor.) At a 25% capacity factor, Amazon’s 1,386 MW worth of solar panels produce enough electricity to “match” about 347 MW of demand. 

Amazon keeps its energy demand in Virginia a secret, but we can be pretty sure its 110 data centers here use way more than that. A 2019 Greenpeace report estimated Amazon’s Virginia data center demand at 1,700 MW in operation or under construction, an amount that would call for 6,800 MW of solar. Amazon rejected Greenpeace’s estimate at the time, but it didn’t supply a better one. More recent estimates suggest Amazon’s energy appetite in Virginia is on its way to 2,700 MW, enough to require the output of around 11,000 MW of solar. 

Luckily for us, Virginia is part of PJM, a regional transmission grid that covers all or parts of 13 states plus Washington, D.C. Generation sources located anywhere in the region can serve a Virginia customer, and Amazon’s map shows it has utility solar and wind projects in several PJM states. By my count, these add up to as much as 4,000 MW of additional renewable energy that could be allocated to Virginia data centers, if Amazon had no other operations in those states that it wanted to power. (Which, however, it does.) 

Adding together its solar in Virginia and elsewhere in PJM still leaves Amazon short of what it likely needs. So, if the company is correct that it has secured enough renewable energy to match all of its demand, a lot of those facilities must be in other regions or other countries. Yet the climate benefit of Amazon’s solar farms in (for example) Spain, which gets more than 50% of its electricity from renewable energy, is significantly less than the climate benefit of solar in PJM, where the percentage of wind and solar combined still hangs in the single digits. 

I will – almost – give Amazon a pass on this point. PJM has been so appallingly slow to approve new generation that Amazon could well have as many projects in the “queue” as online. PJM claims it will catch up in the next year and a half, and when that happens, perhaps Amazon won’t feel the need to obfuscate.

Even if Amazon were “matching” all its energy needs with wind and solar in PJM, though, it’s the second problem that troubles me more. Building solar and wind is cheap; Amazon very likely makes a profit on it. Actually ensuring renewable energy provides all the juice for the company’s operations every hour of every day, on the other hand, would require a heck of a lot of expensive energy storage. And Amazon is not doing that.

Without energy storage, solar delivers electricity only while the sun is shining. The rest of the time, Amazon’s data centers run on whatever resource mix the local utility uses. In both Virginia and PJM’s territory, fossil fuels make up the great majority of the mix. Building more Amazon data centers in Virginia increases the burning of fossil fuels, causing more pollution and raising costs that are borne by the rest of us. 

The self-styled climate hero turns out to be a climate parasite, harming people to make itself look good.

Combining renewable energy with storage to achieve true carbon neutrality isn’t prohibitively expensive. Other leading tech companies seem to be making that extra effort, with Google notable for its commitment to meeting its energy demand with renewable energy and storage on a 24/7 basis.

Amazon’s failure to rise to this challenge explains why, in spite of its massive investments in wind and solar, the company’s carbon footprint actually rose by 34% since the launch of its Climate Pledge in 2019, when it set a target of net zero carbon emissions by 2040. 

That explains why, a year ago, the Science Based Targets initiative, a U.N.-backed organization that monitors corporate net-zero plans, removed Amazon from a list of companies taking action on climate goals. According to press reports, Amazon failed “to implement its commitment to set a credible target for reducing carbon emissions.”  

Among those least impressed with the company’s efforts are its own workers. Last year, Amazon Employees for Climate Justice accused the company of failing in its climate commitments, and the group released its own report this month alleging multiple climate failures, including using “creative accounting” to inflate its achievements.

If Virginia is serious about meeting the climate challenge, we can’t blindly accept rosy claims from corporations whose central goal is not sustainability, but growth. Data centers whose energy demand isn’t met on a 24/7 basis from zero-carbon sources located on the same grid are not part of the climate solution, they are part of the problem. And currently, Amazon’s data centers are making the problem worse.

The Pentagon’s plan to go solar: another chapter in a great American success story

Virginia Gov. Glenn Youngkin can’t run for reelection, so it’s frustrating to see him spending so much time trying to score political points. The latest episode came earlier this month, when according to Fox News, Youngkin sent a letter to Defense Secretary Lloyd Austin questioning the Pentagon’s plan, announced back in January, to install solar panels on the building’s massive roof. Youngkin complained that the plan included no requirements for American-made technology, raising the question “whether American taxpayer dollars will be used to purchase solar equipment from the Chinese Communist Party.” 

A few days later, Fox News reported the Pentagon offered reassurance that it had a “rigorous and extensive oversight process to ensure compliance” with the Buy American Act and other laws requiring domestic content. 

According to this second article, a Youngkin spokesperson quoted the governor as “pleased that Secretary Austin will follow his recommendations to adopt the ‘Made in America’ requirements for procuring Chinese solar panels.”

Younkin’s attempt to snatch victory while still clenched in the jaws of defeat is amusing, but more than a little puzzling. Apparently Younkin is under the impression that solar panels are inherently Chinese.  

Let’s be clear: Solar energy is one of the great American success stories. Americans invented solar photovoltaic technology, nurtured it and led the world in its development for half a century. American ingenuity put solar on the path to becoming today’s low-cost leader for power generation, to the point that it is projected to become the world’s dominant source of electricity by 2050. 

However, as with a lot of American manufacturing, most solar panel production migrated overseas as the technology matured. Starting in 2010, China bet big on renewable energy, investing in solar technology itself and driving down panel prices to the point where most manufacturers in Europe and the U.S. were driven out of business. Only one U.S company remains in the top ten worldwide. 

Chinese companies also likely benefited from the use of forced labor in the production of polysilicon, the raw material for most solar panels. The U.S. banned the importation of solar panels made with forced labor in 2021. 

By then, however, China had developed a mature supply chain and technological know-how to support low-cost production. Today China dominates every aspect of solar manufacturing, with about 80% of the world’s market share. Chinese solar companies have expanded production capacity beyond the ability of world markets to absorb, driving down already-low prices by 42% in 2023. 

Domination of the world market is only half the story, though. China also leads the world in deploying solar at home. China installed as much solar PV capacity in 2022 as the rest of the world combined, and then doubled that in 2023. China also leads the world in offshore wind deployment and electric vehicle sales and dominates production of lithium-ion batteries. 

So the concern that the Chinese are winning the clean energy race is well justified, and Youngkin is not the only American who hates the taste of second place. But our leaders only have two choices: stand around talking trash about the competition, or get in the game. 

That’s what Congress did in passing laws like the Bipartisan Infrastructure Act and the Inflation Reduction Act (IRA) that support American investment in solar panels, wind turbines, electric vehicles and other components of a green revolution. More controversially, President Joe Biden also extended Trump-era tariffs on Chinese-made polysilicon solar panels to give American manufacturers a chance to scale up.  

Not everyone supports tariffs on Chinese-made solar panels, given the inflationary impact of trade barriers and the urgent need to deploy as much renewable energy as possible to lower CO2 emissions. Still, the learning rateof solar is expected to continue driving prices lower over the long term. Even with a less-mature, more expensive supply chain, American-made panels are projected to become cheaper than imported panels by 2026.

One year after the IRA’s passage, a Goldman-Sachs analysis found the law was meeting its objectives of driving private sector investment and job creation in the clean-tech sector, including manufacturing. This month, Wood Mackenzie reported that U.S. solar manufacturing capacity increased 71% in the first quarter of 2024, making it the largest quarter of solar manufacturing growth in history. 

The Pentagon is not known for caring about saving money, so maybe it isn’t surprising that it is only now following the example of millions of Americans by putting solar panels on the roof. Defense Department officials say the move is intended to support the resurgence in American manufacturing and to deliver the benefits of increased energy resilience and reliability, including having an uninterrupted power source in case of a cyberattack or a grid outage. 

Low-cost, clean power, resilience and energy security are all part of the great American success story that is solar energy. A note of congratulation, not complaint, would be the better response from Youngkin.
