On December 15, 2011, the California Public Utilities Commission adopted Decision 11-12-052, implementing Portfolio Content Categories for the 33% Renewables Portfolio Standard (RPS) Program in California. The Decision implements portions of Senate Bill (S.B.) x1-2, which created the 33% RPS Program. S.B. x1-2 established three categories of RPS-eligible electricity, applicable to RPS contracts executed after June 1, 2010:
- Category One includes electricity from RPS-eligible resources that have their first point of interconnection with a California balancing authority, RPS-eligible resources with a dynamic transfer arrangement with a California balancing authority, and RPS-eligible resources scheduling their electricity directly into a California balancing authority without substituting electricity from another source.
- Category Two includes firmed and shaped RPS-eligible electricity.
- Category Three includes transactions that do not meet the criteria of Category One or Two, including unbundled renewable energy credit (REC) transactions.
