Ignoring state climate rules, Dominion decides what carbon regulations should look like

For several years now, Dominion Energy Virginia has factored into its plans an assumption that electricity from carbon-emitting power plants will eventually include a cost reflecting CO2’s role as the primary driver of global warming. Dominion says it has even integrated this into its corporate goals, targeting an 80 percent reduction in CO2 emissions by 2050.
That promise may be more propaganda than corporate lodestar, but in any case the utility’s Integrated Resource Plans regularly point to the probability of future carbon regulations as a reason to build new renewable energy facilities and close old coal plants.
Planning for constraints on CO2 emissions proved wise this spring when Virginia’s Department of Environmental Quality finalized a state carbon cap-and-trade program. The DEQ regulations call for Virginia power plant owners to trade carbon allowances with those in the member states of the Regional Greenhouse Gas Initiative (RGGI). A Republican budget maneuver has delayed implementation of the new rules, but once they take effect they are expected to hasten the retirement of expensive old coal plants and support investments in new renewable energy projects.
But it’s not the DEQ regulations that Dominion is planning around. The utility’s 2019 update to its 2018 IRP, filed with the State Corporation Commission on Aug. 29, treats the DEQ regulations as hypothetical. Instead, it posits some unspecified future federal carbon regulations that, apparently, it would like much better.
The update describes three alternative scenarios, down from five in the 2018 IRP. The first is a “base case” that assumes no carbon emission constraints. The second assumes the state carbon limits take effect as well as some future federal regulations, and the third assumes federal (but not state) limits. However, the cover letter makes it clear that only the third scenario actually describes what Dominion intends to do. As it happens, that is the most expensive— and most profitable —plan.
The primary feature of the base case is that it keeps some old coal units running that will be closed in the other scenarios. According to Dominion, this makes it the least-cost approach to meeting electricity demand. Whether that’s true is a matter of dispute; these units hardly run at all any more, and experts for environmental organizations in the IRP hearing testified that retiring them will save money for customers.
It suits Dominion’s political strategy, however, to pretend that coal remains a low-cost option. This fiction makes coalfield legislators happy, and it allows Dominion to blame rising electricity rates on environmental regulations instead of on its own profligate spending and excess profits.
But Dominion Energy made a big bet on fracked gas, not coal. It won’t fight to keep outdated coal plants online and spewing out CO2 if it’s cheaper to close them. Gas plants are another matter. Dominion Energy’s massive investments in gas transmission and storage make the company keen to keep Virginia gas plants running full-tilt, and to build as much new gas generation as possible.
For that reason, Dominion hates the DEQ regulations. It warns the regional cap and trade plan will result in power from outside the state replacing electricity from Dominion’s combined-cycle gas plants, which provide baseload power. Dominion argues this will lead to higher, rather than lower, carbon emissions as well as higher consumer costs.
DEQ and others disagree on both counts, though the SCC takes Dominion’s view. So although Dominion labels its second scenario RGGI-compliant, it treats the DEQ regulations as hypothetical, as if Gov. Ralph Northam might change his mind any day now and order them scrapped.
Instead, Dominion offers its third scenario, positing only unspecified and (with Trump as president) truly hypothetical future federal carbon regulations. In Dominion’s fantasy, a federal plan will be strong enough to support Dominion building profitable new renewable energy and storage projects, but not so strong that it can’t also build a bunch of new gas plants.
Ergo, that’s what Dominion is shooting for. The cover letter accompanying the IRP update makes it clear that Dominion is already pursuing projects that appear only in the third plan. These include a 300 MW pumped hydro storage project that will take a decade to develop and cost upwards of $1.5 billion (if indeed it pans out), and an 852 MW offshore wind project slated for 2025, a year later than what Dominion told investors in March.
The third scenario also includes more than 3,000 MW of solar between now and the end of 2034, but that’s actually a whole lot less solar than under the RGGI scenario. Even the base case has more solar. Go figure.
Still missing is the rest of the 2,000 MW of offshore wind that the Virginia lease area can support. Also still missing are thousands more megawatts of wind and solar that Virginia would need if, instead of a gas-friendly plan, the federal government were to enact regulations actually sufficient to the climate crisis.
Dominion has not even modeled that possibility. The update’s third scenario still includes 10 new fracked-gas combustion turbines, a total of 2,425 MW, with two units coming online every year from 2022 through 2026.
Maybe the Dominion executive team thinks it knows more than the rest of us do about the federal climate plan we’ll see once Donald Trump is sent packing in 2020. More likely, Dominion is simply using its IRP carbon assumptions to bolster its case for more spending and higher profits.
In which case, the more things get updated, the more they stay the same.
