Double-Counting Risks in New Market Accounting Frameworks for State Clean Energy Programs

This policy brief for state policymakers and regulators describes how proposed frameworks for tracking and reporting greenhouse gas (GHG) emissions in new regional wholesale electricity markets for the Western Interconnection could impact the integrity of state clean energy and GHG programs. It provides recommendations including data coordination between these markets and the Western Renewable Energy Generation System (WREGIS), requiring renewable energy certificate (REC) ownership for allocation of renewable energy, and moving towards an integrated all-resource regional certificate tracking system.
