The Virginia General Assembly is still poised to pass a vastly expanded mandate for future utility battery storage systems, but the bills are no longer passing unanimously. At least some discussion of the ratepayer cost impact has come up in committee and floor discussions since being raised by Baconโs Rebellion. Most Republicans are now on record as opposed.

The effort was given a strong cheerleading push from Virginia Mercury in a story Thursday that made no effort to estimate that customer cost (but also no effort to dispute Baconโs Rebellionโs figures.) The Mercury article also glossed over the incredibly important detail that battery storage in megawatts is a useless measurement, and the real metric is megawatt hours.
The cost should be calculated in dollars per megawatt hour. At this point, the legislative histories on the bill still do not show any official estimate of the capital costs or ratepayer impact. On that front, legislators still seem to enjoy not hearing any bad news.
The bill is being pushed by Dominion Energy Virginia, among others, and Mercury quoted one of its contract lobbyists saying the bill gives the regulatory State Corporation Commission โfull authority to agree with the targets set in the code or alter them up or down and we think that is the right approach.โ
What she ignores, and she avoided this point in committee testimony witnessed by Baconโs Rebellion, is that question is the only discretion being left to the SCC.ย Elsewhere in the Virginia Clean Economy Act, the regulators are all but mandated to approve the first 3,100 megawatts of battery storage as being โin the public interestโ by law.ย The traditional tests of reasonableness, prudence and necessity are not applied.ย The General Assembly already decided those questions and didnโt set any cost cap, either.
