Renewable energy makes small gains in Virginia’s 2013 legislative session

The Virginia General Assembly will soon wrap up its work on the 2013 legislative session. Renewable energy advocates began the session with high hopes for a series of bills that promised to reform our renewable energy law, expand net-metering, and open up new opportunities for financing solar systems and small wind turbines.

So how did we do? Well, this is Virginia. Progress is slow, the utilities are powerful, and half the legislature doesn’t believe in climate change. On the other hand, they do believe in business. Under the circumstances, we did okay.

Renewable Portfolio Standards: bye-bye, bonuses

Readers of this blog already know the long, miserable tale of Virginia’s weak and ineffective, voluntary renewable portfolio standard (RPS), which has enriched utilities with tens of millions of dollars in incentives without bringing any new renewable energy projects to Virginia. This year the legislature went halfway to fixing the problem. Legislation negotiated between the office of the Attorney General and the utilities will deprive utilities of future ill-gotten gains for meeting the RPS law, but won’t change the pathetic nature of the law itself.

Stripping out the RPS incentives was only part of a bigger, more complex bill that sweetens the deal for utilities in other ways, so it’s hard to judge whether the legislation as a whole marks a victory for consumers. Skeptics will note that Dominion’s stock price has actually gone up several percentage points since the deal was announced, which you wouldn’t expect if the AG were correct that the bill will save consumers close to a billion dollars over time.

What is clear is that the RPS remains as voluntary and as crummy as it ever was, but the utilities can no longer use it to rip off ratepayers while pretending to be good citizens. Some environmental groups consider stripping out the incentives a bad thing, on the theory that only by giving utilities a bonus can we expect them to meet the goals. Other groups (including the Sierra Club) believe Dominion, at least, will want to maintain its greenwashed public image by continuing to meet the RPS goals, and that ending the consumer rip-off is worth celebrating.

Sure, if the goals had brought wind and solar to Virginia, the Sierra Club would have considered the incentives a tolerable price to pay. As it happened, Dominion and the other utilities continuously rebuffed efforts over the years to improve the RPS. Had Dominion approached the RPS as an opportunity to bring real renewable energy to Virginia rather than as a cash cow to be milked for its own advantage, the company would have saved itself a public relations fiasco and likely kept its bonuses, too. Surely, someone at HQ should be out of a job right now.

Taking the long view, it is also worth noting that getting rid of the free money is a necessary first step towards a mandatory RPS in Virginia, which would unleash market forces for renewable energy that don’t emerge with a voluntary law. Utilities would oppose such a move more vigorously if they still had incentives to protect that were available only under the voluntary program.

. . . but reform efforts fail again

These views all assume the legislature will someday pass a bill to improve the goals and bring wind and solar projects to Virginia, without which the RPS is meaningless anyway. Surely legislators must recognize how pointless it is to have an RPS that can be met with out-of-state, pre-World War II hydro, plus some trash and wood-burning and a few assorted projects that put no power on the grid. (Even without the performance incentives, utilities remain entitled to pass along to customers the cost of meeting the RPS goals.)

Bills to improve the goals should have passed the legislature this year as part of the reform package. HB 1946 (Lopez) and SB 1269  (McEachin) even received the support of Dominion Power for provisions that would limit most future purchases for the RPS to high-quality projects like wind and solar. What killed the bills seems to have been a combination of opposition from vested interests and sheer cussedness on the part of some Republicans, who were engaged in partisan maneuvers that had nothing at all to do with renewable energy.

As usual, we are left hoping for better luck next year.  Meanwhile, however, a couple of other RPS bills made incremental progress. Most notably, HB 1917 (Surovell) adds solar thermal energy to the definition of renewable energy; as of this writing it has passed the House and is on the Senate floor.

A loss for more honest competition among fuels

There are more ways to support renewable energy than through an RPS, of course. One of my favorite bills would have required utilities and the State Corporation Commission to consider the long-term price stability of fuels used in electric power generation. HB 1943 (Lopez) would have helped price-stable wind and solar compete against notoriously price-volatile natural gas. It’s an idea that should appeal to fair-minded conservatives, so it’s a shame it hasn’t gained traction since first being introduced in 2012. However, it died in committee in the face of opposition from Dominion Power, which doesn’t want any interference with its plans for new natural gas plants.

Power Purchase Agreements get a “pilot”

Two bills passed the legislature to allow some third-party power purchase agreements (PPAs) for wind and solar within Dominion’s territory. Under a PPA, an installer retains ownership of the solar equipment, with the customer buying the electricity that is generated. This arrangement has two primary advantages: the customer can “go solar” with no money down and no responsibility for the equipment; and in the case of a tax-exempt entity like a church or a university, it provides a way to access federal tax credits worth 30% of the system cost.

The bills were designed to prevent a recurrence of a dispute that erupted in 2011 when a Staunton-based solar company, Secure Futures, installed a large solar system at Washington & Lee University under a PPA. Dominion issued “cease and desist” letters insisting that only it could sell electricity in its assigned territory. Although Virginia law is unclear on this point, the university and the solar company capitulated in the face of massive litigation costs. Since then Dominion’s army of lawyers has proven as effective as any statute in stopping further efforts to use PPAs in Virginia.

This year’s bills, SB 1023 (Edwards) and HB 2334 (Yancey), were originally written to allow third-party PPAs wherever customers can currently install renewable energy systems that they own themselves. They were significantly scaled back to win acceptance from Dominion Power. (AEP and the coops wouldn’t play at all, so legal ambiguity remains the rule in their territories.)

The bills allow up to 50 megawatts’ worth of solar and wind installations using PPAs, in Dominion territory only, as a pilot program.  Whether net-metered or not, they will be counted against the current net-metering cap of 1% of the utility’s generation. Tax-exempt entities can have a facility of any size up to 1 megawatt (500 kW if they net meter); taxable entities must have a minimum size of at least 50 kW (so no homeowner need apply). PPAs that do not meet the requirements are expressly prohibited in Dominion territory.

Agricultural net metering, yes; community net metering, no

A bill to allow agricultural net metering also passed this year. HB 1695 (Minchew) allows the electricity from a single solar, wind, or digester gas facility to be attributed to two or more electricity meters as long as they are all on the same property and have the same owner. Thus, for example, a farmhouse, barn and other out-buildings can all share in the benefits of solar panels on one of the buildings, even if each building is separately metered.

Originally the bill would also have enabled community net metering, sometimes known as solar gardens, but the utilities opposed it. Bowing to political reality, Delegate Minchew scaled it back. The bill is notable, however, for making progress without including any provisions that seem capable of doing mischief.

A note about all the bills: In Virginia, the governor can sign a bill, veto it, or send it back to the legislature with amendments of his own, so none of these bills are final as of this writing.

For electric power generation, the end of fossil fuels is in sight

The rap on renewable energy is that it’s too variable to meet society’s demand for a constant supply of electricity. The answer to the problem turns out to be: More renewables.

111022-N-OH262-322Climate change is acting like an ever-tightening vise on our energy options. Each year that passes without dramatic decreases in our use of carbon-emitting fuels means the cuts we have to make simply get more drastic. By 2030, say experts, we must entirely replace coal with efficiency and renewable energy, or fry. Even the most intrepid environmentalists wonder if it can be done without huge price hikes and wholesale changes in how we live and use energy–changes that society may not accept.

A new study out of the University of Delaware shows it is possible to power the grid 99.9% of the time with only solar and wind energy, at a cost comparable to what we are paying today. This counters the conventional wisdom that we will always need large amounts of fossil fuel as a backup when the wind doesn’t blow and the sun doesn’t shine. It also means the goal of getting largely beyond fossil fuels by 2030 is not just achievable, but practical.

The study focused on a regional transmission grid known as PJM, which encompasses parts or all of fourteen states, mostly in the Mid-Atlantic. Researchers ran 28 billion computer simulations to find the most cost-effective combinations of wind and solar that could power the entire grid, at the least possible cost and with minimal amounts of energy storage. The winning combination relied on natural gas turbines for backup on only five days out of the four years modeled.

The study authors looked for the least cost taking account of carbon and other external costs of fossil fuels, which are not being accounted for today, but they also assumed no technology improvements over time, making their cost estimates conservative overall. All the least-cost combinations used much more storage than we have today, but needed it for only 9 to 72 hours to get through the entire four years modeled.

The secret to dealing with the inherent variability of wind and solar, it turns out, is to build even more wind and solar. One wind turbine is unreliable, but tens of thousands spread across a dozen states greatly reduces the variability problem, and tens of thousands of wind turbines balanced with millions of solar panels is better still. To get to 99.9% renewables, you keep adding wind turbines and solar panels until you are producing three times the electricity that you actually need to meet demand. To power the grid with renewables just 90% of the time, you would have to produce “only” 1.8 times the electricity needed. (And yes, we have the windy sites and the sunny places to support all those projects.)

While it may sound strange to build more generation than you need, that is already the way grid operators ensure reliability. To take one example, if you were in Virginia when the “Big One” struck in 2011, you will recall that the earthquake caused the North Anna nuclear plant to shut down for four months. Nuclear energy provides a third of the electricity in Dominion Virginia Power’s service territory, and yet the lights stayed on. That’s because the grid wizards at PJM simply called on other power sources that had been idle or that had spare capacity.

The other component of reliability is the ability to match demand for power, which rises and falls with the time of day, weather, and other factors. So-called “baseload” plants like nuclear, coal, and some natural gas turbines don’t offer that flexibility and must be supplemented with other sources or stored energy. PJM currently uses more than 1,300 different generating sources, as well as about 4% storage in the form of pumped hydro. The right combination of other sources can replace baseload plants entirely.

Pairing wind and solar improves their ability to meet demand reliably. Onshore wind tends to blow most strongly at night, while solar energy provides power during the peak demand times of the day. Offshore wind power is also expected to match demand well. Combining them all reduces the need for back-up power.

But until now policy makers have assumed that solar and wind won’t be able to power the grid reliably, even when combined and spread out over PJM’s more than 200,000 square miles, and with the addition of wind farms off the coast. Critics have insisted that renewable energy requires lots of back-up generating capacity, especially from some natural gas turbines that can ramp up and down quickly. New gas turbines have even been designed specifically to integrate with renewables in anticipation of increasing amounts of wind and solar coming onto the grid.

This makes the work of the U. Delaware researchers a game-changer by showing that wind and solar can be backed up primarily by more wind and solar. And so we can begin planning for a future entirely without fossil fuels, knowing that when we get there, the lights will still be on.
