Renewable energy advocates are hoping that 2020 will be the year Virginia finally begins to make wind and solar the centerpiece of its energy planning, rather than a grudging add-on. The General Assembly will consider at least two bills that adopt a mandatory renewable portfolio standard as well as legislation to lower carbon emissions and open the private market to greater investments in renewables.
But good intentions don’t always produce effective legislation. Sloppy drafting causes unanticipated consequences. Minor amendments offered by an opponent produce major consequences only the opponent anticipated.
For a case in point, let’s consider Virginia’s existing, voluntary RPS. Worse than useless, it has enabled all kinds of mischief by defining “renewable energy” to include things that do not contribute carbon-free renewable power to the grid
As currently written, our renewable portfolio standard never has been, and never will be, responsible for a single electron of wind or solar energy. That means that any bill that takes as its starting point the definition that currently exists in the Virginia Code, or even uses the term “renewable energy” without narrowly defining it, risks failing right out of the gate.
Part of the problem is biomass. But a much greater problem is one that has been largely overlooked, mainly because no one understands it. It’s called “thermal” energy, and it is a major piece of mischief all by itself.
Added to the statute in 2015, thermal renewable energy certificates quickly became the primary means for Dominion Energy Virginia to meet its RPS targets, after counting the energy from the utility’s own hydro and biomass facilities and those from which it buys power under contract.
The thing is, no one seems to know where thermal RECs come from. The code offers three possibilities. One is “the proportion of the thermal . . . energy from a facility that results from the co-firing of biomass.” Another is “the thermal energy output from (i) a renewable-fueled combined heat and power generation facility that is (a) constructed, or renovated and improved, after January 1, 2012, (b) located in the Commonwealth, and (c) utilized in industrial processes other than the combined heat and power generation facility.” Finally, there is a tiny (and mainly unused) category for solar hot water systems and swimming pool heating.
The second definition, added to the code in 2015, is so specific that it was clearly written with a particular industrial facility or facilities in mind. From that definition, we can determine that thermal RECs don’t represent renewable electricity added to the grid.
What no one but Dominion seems to have known was that thermal RECs would instantly become the leading category for RECs, and one that would eliminate any chance for wind or solar to ever compete for RPS dollars in Virginia.
The Virginia statute is an oddity. “Thermal” is not a recognized category in the regional registry for purchase and sale of RECs among utilities and voluntary buyers (known as PJM GATS). I also haven’t found another state RPS program that includes thermal in its definition of renewable energy, aside from solar thermal.
A year ago I asked Dominion what kind of industry supplies thermal RECs; I was promised an answer, but none came. So a week ago I asked the staff of the State Corporation Commission. They don’t know either.
Every year in November, Dominion submits a report to the SCC about its renewable energy activities, including information the law requires about a utility’s RPS program. The reports are available on the SCC website.
None of the reports include any discussion of thermal RECs, including the report submitted covering 2015, the first year these RECs were allowed. The reports don’t indicate where thermal RECs come from, what kind of industrial process produces them, or whether there might be a lot more available that could supply Dominion in the future as RPS goals increase.
However, by law Dominion has to provide other information that, read together, allows us to deduce a few bits of information about thermal RECs, and about their role in the RPS:
- They are generated by one or more Virginia facilities.
- The facility or facilities were placed in service this decade, confirming that we are talking about that second meaning of thermal.
- The facilities are not owned by Dominion.
All or almost all the RECs Dominion purchases are thermal RECs. Thermal RECs make up all or nearly all the energy and RECs Dominion has banked to use in future years. (Virginia law allows a utility to hang on to a REC for up to five years after it was generated.) If these were wind and solar RECs instead of thermal RECs, the value of the banked RECs would exceed $40 million, even at the low REC prices currently prevailing in the PJM marketplace.
I compiled the information from these reports into the table below. The 2019 filing, containing information for 2018, also gives us a view into the current year. It states: “The company began 2019 with banked renewable energy and RECs of 4,252,354 MWh and expects to have a bank of approximately 4,113,477 MWh of renewable energy and RECs toward future RPS targets at year-end 2019.”
As you can see, Dominion has enough RECs banked that, when added to generation from Dominion’s own or contracted renewable energy facilities, Dominion has no need to purchase any RECs from any source until 2022 (when it still won’t need much).
Dominion doesn’t report what it paid for thermal RECs, but they are undoubtedly cheaper than any other qualifying source. One reason: with no competitive market for thermal RECs, Dominion is almost certainly the only buyer. In antitrust parlance, the term for this is “monopsony,” a word I hope you will now want to work into your dinner table conversation.
Monopsony power includes the power to set the price of a product, because the seller has no one else to sell to. In the case of thermal RECs, we don’t know who the seller is, but clearly its primary business is not the production of thermal RECs for sale. In fact, the money it gets for these RECs likely represents a windfall, and it is happy to get anything that covers its administrative cost in documenting its use of thermal energy.
On the other hand, Dominion doesn’t have to be overly stingy, since Virginia law allows the utility to pass on to ratepayers the cost of purchasing RECs for the RPS. One can imagine Dominion CEO Thomas Farrell having a nice dinner with the CEO of the corporation owning the industrial facility that uses the thermal energy, and together deciding what Virginia consumers will pay for these RECs. As long as it is less than the cost of other RECs available to Dominion, who will complain?
Whatever the price is, a monopsony price of thermal RECs will be less than the price of wind and solar RECs in Virginia, because wind and solar have a competitive market and buyers who are willing to pay more.
For years, critics have complained that the voluntary RPS is a failure for every purpose except greenwashing. But with no appetite for reform in the General Assembly, it’s been easy to ignore how the definition of renewable energy was expanding like a slime mold escaping its petri dish.
This year, though, the reformers are on the move. One or more bills requiring utility investments in renewable energy seem likely to gain traction. Advocates will be keeping their fingers crossed—and reading the definitions.

[Update: Several astute readers pointed me to information indicating that the source of the thermal RECs is WestRock, a Georgia-based multinational paper company that burns wood and black liquor (a toxic byproduct of the pulping process) as a power source. WestRock is the single biggest emitter of air toxics in Virginia, with its facility in Covington topping the ranks as the Commonwealth’s number one air polluter, ahead of even Dominion’s biggest and dirtiest coal plant. So when you are sorting through junk mail or have a cardboard box delivered, take time to savor the moment. Maybe you didn’t actually help make that paper, but you probably contributed your small mite to WestRock CEO Steven Voorhees’ $18 million compensation package.]
