Persons interested in Appalachian Power Company’s proposal to implement a voluntary rate schedule for customers who own electric vehicles (Schedule PEV) may file comments on the matter with the Virginia State Corporation Commission clerk by July 15, the commission said in a May 6 order.
As noted in the order, Appalachian Power filed its petition with the commission for approval to implement Schedule PEV in April.
The new and optional Schedule PEV tariff would allow residential customers who are receiving standard service to charge their electric vehicles (EVs) on a time of day rate schedule, the commission said, adding that to take service under Schedule PEV, a customer must have an advanced metering infrastructure (AMI) meter installed.
Participating customers would use charging stations that are programmed to consume electrical energy primarily during off-peak hours specified by the company to charge their EVs.
The commission also said that the rates, as well as the peak and off-peak periods, under Schedule PEV would initially be similar to the rates, as well as peak and off-peak periods, contained in the residential time of day rate, Schedule R.S.-T.O.D., with modifications to reflect current, lower submetering costs and an off-peak period adjusted to be less likely to overlap with winter heating peaks.
According to the company’s petition, Schedule PEV also eliminates the monthly basic service charge of $9.82 and adds an additional 1.05¢/kWh on the off-peak charging rate.
The company said that it may request to modify the rates in Schedule PEV during its next base rate proceeding in 2020, the commission noted.
According to the company, the commission said, a customer with a typical EV consumption of 2,700 kWh annually that takes service under Schedule PEV and exclusively charges an EV off-peak would save an average of $86.51 annually as compared to the standard residential rate schedule, Schedule R.S., and $89.41 annually as compared to Schedule R.S.-T.O.D.
The company asserts that Schedule PEV’s rates are just and reasonable, and that enabling customers to become accustomed to charging their vehicles off-peak would help the company avoid the addition of significant generation, transmission, and distribution capacity to supply that load, the commission said.
Among other things, the commission said that its staff is to file with the clerk a report on the company’s petition by July 31, and that the company may file with the clerk any comments on that report by Aug. 15.
