Energy efficiency programs; incremental annualsavings. Provides that it is in the public interest and the policyof the Commonwealth to deploy demand-side management programs andenergy efficiency measures throughout the Commonwealth to achievethe greatest possible reductions in energy consumption. The billpermits the State Corporation Commission to increase or decreasean investor-owned electric utility's combined rate of return basedon the utility's success in complying with energy efficiency programtargets in existing law. Additionally, the bill states that "in thepublic interest" for the purpose of assessing energy efficiency programsmeans that the Commission determines that the program is cost-effective.Finally, the bill directs the Commission to promulgate regulationsno later than December 31, 2025, establishing a single, consistent cost-effectiveness test for use in evaluating proposed energy efficiency programs. Energy efficiency programs; incremental annual savings. Provides that for the 2029 program year and all subsequent years, "in the public interest" for the purpose of assessing energy efficiency programs means that the State Corporation Commission determines that the program is cost-effective. The bill directs the Commission to promulgate regulations no later than September 30, 2025, establishing a single, consistent cost-effectiveness test for use in evaluating proposed energy efficiency programs. The bill requires Dominion Energy Virginia and Appalachian Power Company to track, quantify, and report to the Commission the incremental annual savings, as defined in the bill, achieved by such utility's energy efficiency programs. This bill is identical to SB 565. Energy efficiency programs; incremental annualsavings.
