Below is the official submission by CFACT to the Virginia’s State Corporation Commission (SCC) this week. It not only supports the Commission’s 42% “performance guarantee” imposed on Dominion Energy’s (to include its renewable efforts with offshore wind), a standard Dominion is appealing because it makes their project uneconomical, but we advocate the standard be increased to 50% in order to better protect rate payers.
CFACT may be the only NGO advocating for the SCC to not just deny Dominion’s appeal, but to reform the rule to make it even more stringent.

Re: PUR – 2021-00142
Petition of Virginia Electric Power Company
for Limited Reconsideration
COMMENTS of CFACT
In its Petition for Reconsideration, the Virginia Electric Power Company (“Dominion”) requests
that the Commission remove the “performance guarantee” adopted by the Commission in its
Final Order dated Aug 5, 2022. Dominion states that “the Commission’s unprecedented
imposition of an involuntary performance guarantee condition on its approvals is untenable”,
and that if the performance guarantee is ordered it will prevent the Project from moving
forward and the Company will be forced to terminate all development and construction
We believe, on the contrary, that a performance guarantee is essential to protect ratepayers in
this unprecedented situation. To that end we offer the following derivation of the proper
performance requirement, which we respectfully request the SCC to implement a factually
supported Dominion OSW capacity factor threshold requirement
Dominion’s petition reopened the 42% issue includes this key statement:
“In addition to exceeding the Commission!s legal authority, by adopting the performance
recommendation of the Office of the Attorney General!s Witness Norwoodin a mere five lines of
pre-filed testimony—for a 42% capacity factor threshold measured on a rolling three-year
average, the Commission has imposed a requirement that is contrary to the factual support it
purports to rely upon, improper in scope, and unreasonably vague in application.” (Emphasis
We are proposing a different threshold, one based on the VCEA compliance plan in Dominion’s
2021 IRP update, so it is clearly based on factual support. It happens to be higher than 42%, in
fact it is a minimum of 50%.
Note that this is a legal threshold, a performance requirement. It is what Dominion must do, not
the wind, in order to maintain system reliability. It is not a specified capacity factor for the OSW
project. On the contrary, it is a “make or buy” requirement for the project to maintain reliability.
2. Derivation of the minimum threshold
The crunch begins in 2026 with the planned shutdown of roughly 2,600 MW of combustion
generating capacity being completed that year. This capacity is replaced with a combination of
solar power and the OSW wind project. See Figure 2.2.3: Alternative Plan C (nameplate MW) in
the IRP update for specifics.
Something like 8,000 MW of solar capacity has been built or contracted for by then, so there
may be no reliability problem during the day. But at night there is only the 2,600 MW OSW
capacity, which is just equal to the shutdown combustion capacity.
There is some battery storage capacity, but it is very small compared to the needed amount.
There is a planned storage capacity of about 800 MW which at the standard 4 MWh per MW
gives just 3,200 MWh. But 2,600 MW for, say, 12 hours when there is no solar requires 31,200
MWh or roughly ten times as much. In fact, that storage would likely all be needed to try to
reliably get 12 hours of supply out of the solar generators.
If the OSW make or buy requirement is one half a day then that equates to a 50% capacity
factor, not the proposed 42%.
This 50% required OSW capacity factor does not mean the project will physically produce this
much electricity. It is a legal “make or buy” reliability requirement.
Given the pronounced intermittency of OSW there will have to be significant power purchases
to maintain reliability under this VCEA compliance plan, no matter what required capacity
factor is specified. That this 50% is greater than the expected project output is thus irrelevant.
This is a “make or buy” capacity factor.
Note that a more refined analysis of Dominion’s VCEA compliance plan is likely to lead to an
even larger requirement. In particular, the period of solar generation is likely to be considerably
less than 12 hours in winter.
