Solar Voluntary Renewable Electricity Program

The Voluntary Renewable Electricity (VRE) Program allows purchasers of eligible voluntary renewable electricity to request retirement of allowances on their behalf under the Cap-and-Trade Program. The VRE Program supports renewable electricity purchases that are not mandated by the Renewables Portfolio Standard (RPS), and provides a mechanism for the recognition of voluntary purchases of renewable electricity in the Cap-and-Trade Program. The Cap-and-Trade Regulation specifies a percentage of allowances to be set aside each year for VRE purposes.

ARB will retire allowances each year for eligible voluntary renewable electricity generated in the previous year. The regulation provides one half percent of the annual budget for the budget years in the first compliance period, and then a quarter of a percent for the budget years in the subsequent compliance periods, to be dedicated to a voluntary renewable electricity account, from which allowances may be retired. The total allowances that may be retired for each vintage year are reflected in the table below.
