Under pressure from the SCC, Dominion reveals the true cost of data centers

Ever since data centers started spreading across the Virginia landscape like an invasive pest, one important question has remained unanswered: How much does the industry’s insatiable demand for energy impact other utility customers? Under pressure from the SCC, this month Dominion Energy Virginia finally provided the answer we feared: Ordinary Virginia customers are subsidizing Big Tech with both their money and their health.

Dominion previously hid data centers among the rest of its customer base, making it impossible to figure out if residents were paying more than their fair share of the costs of building new generation and transmission lines. Worse, if data centers are the reason for burning more fossil fuels, then they are also responsible for residents being subjected to pollution that is supposed to be eliminated under the 2020 Virginia Clean Economy Act (VCEA). The VCEA calls for most coal plants in the state to be closed by the end of this year – which is not happening – and sets rigorous conditions before utilities can build any new fossil fuel plants. 

Dominion’s 2023 Integrated Resource Plan (IRP), filed a year and a half ago, projected steep increases in energy demand and the cost of electricity. The utility asserted that for reliability purposes it needed to keep coal plants operating, build new methane gas generating units without meeting the VCEA’s conditions, and add small nuclear reactors beginning in 2034.

Dominion’s failure to file a plan that complied with the VCEA led to an unusual stalemate at the SCC, with the IRP neither approved nor rejected. Ignoring the foul-weather warning, Dominion filed a similarly-flawed 2024 IRP in October.  None of the modeled scenarios showed coal plants closing, none met the energy efficiency requirements set by law, and all proposed building new gas and nuclear reactors, with the first small nuclear plant now pushed off to 2035.

Neither of the two filings separated out the role of data centers in driving the changes. 

Even before the 2024 IRP was filed, though, the SCC directed the utility to file a supplement. It was obvious the IRP would project higher costs and increased use of fossil fuels. How much of that, the SCC demanded to know, is attributable to data centers? 

A lot, as it turns out. Though Dominion continues to obfuscate key facts, the document it filed on November 15 shows future data center growth will drive up utility spending by about 20%. Dominion did not take the analysis further to show the effect on residential rates.  

The filing also shows that but for new data centers, peak demand would actually decrease slightly over the next few years, from 17,353 MW this year to 17,280 MW in 2027, before beginning a gentle rise to 17,818 MW in 2034 and 18,608 MW in 2039. 

In other words, without data centers, electricity use in Dominion territory would scarcely budge over the next decade. Indeed, the slight decrease over the next three years is especially interesting because near-term numbers tend to be the most reliable, with projections getting more speculative the further out you look.  

Surprised? You’re not alone. We’ve heard for years that electric vehicles and building electrification will drive large increases in energy demand. When Dominion talks about the challenges of load growth, it cites these factors along with data centers, suggesting that ordinary people are part of the problem. We’re not. 

Decreasing demand is a testament to the profound effect of energy efficiency, as advances in things like lighting, heat pumps and other appliances allow consumers to do more with less. Presumably, the electrification of transportation and buildings will eventually outpace gains in efficiency – no doubt reflected in the projections for slightly increasing demand over the 2030s – but the effect is still modest. Electrification is not to blame for demand growth; data centers are.

In a future without new data centers, there should be no reason for Virginia’s energy transition to get off track. Solar, offshore wind and battery storage could increasingly displace fossil fuels, clean our air and bring down greenhouse gas emissions at an orderly pace. 

At least, that’s the intuitive result, though Dominion fights hard to counter it. The new filing is supposed to show what a VCEA-compliant plan would look like without data centers, but it retains assumptions from its IRPs that skew the results in favor of fossil fuels. These include limiting energy efficiency and artificially capping the amounts of solar and storage that its computer model could select. Obviously, if you won’t invest in low-cost energy efficiency and solar, you need more of something else. 

Dominion’s computer model also doesn’t choose offshore wind in spite of the fact that the 2,600-MW Virginia Coastal Offshore Wind project is under construction. No doubt the higher cost of offshore wind is responsible for this counter-factual omission, but again, leaving it out requires that something else be selected. Nuclear similarly doesn’t make the cut due to cost. 

By limiting or eliminating all zero-carbon options, Dominion would like you to conclude that, with or without data centers, it “needs” more gas plants.

There are other reasons to be skeptical of this manufactured result. As with the 2024 IRP itself, Dominion does not appear to have incorporated the social cost of carbon in its supposedly-VCEA-compliant plan, a mandatory consideration for any new fossil fuel generation. It’s also worth noting that Dominion will once again have to buy carbon emission allowances to run its coal and gas plants now that a court has nullified Gov. Glenn Youngkin’s illegal withdrawal of Virginia from the Regional Greenhouse Gas Initiative (RGGI). (Youngkin has vowed to appeal.) 

On the other hand, President-elect Donald Trump and Republicans in Congress seem likely to overturn new EPA regulations tightening pollution standards for fossil fuel plants. That would make fossil fuels appear cheaper by shifting costs onto residents in the form of worse health outcomes and climate-related weather disasters. 

In addition to showing what the energy mix might look like without data centers, the SCC directed Dominion to identify which of its approximately 200 planned transmission projects were needed solely because of data centers. The 4-page table in Dominion’s supplemental filing reveals that about half of the projects are solely data center-driven, with two or three dozen more serving a mix of customers that includes data centers. I tried to add up the numbers but lost track at a billion dollars’ worth of projects needed solely for data centers – and I was still on the second page. 

There is one more caveat to keep in mind. Since the SCC’s order applied only to future growth, Dominion’s new numbers don’t show the cost and energy impact of data centers in operation today. Data centers already make up a quarter of Dominion’s sales, and that growth was the main reason the utility pivoted back to fossil fuels in its 2023 IRP. 

Still, most of the data center growth lies ahead of us, as does Dominion’s plans for new fossil fuel and nuclear generation. With state leaders avidly chasing more data centers in the name of economic development, ordinary Virginians are left to watch the assault on their energy supply, their water, and their environment and wonder: Is anyone going to fix this?

The clean energy revolution will continue

by

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.
