Berkeley Lab tracks and analyzes state renewables portfolio standards (RPS) and clean electricity standards (CES), in order to inform policy-makers, program administrators, and others about the design and impact of these policies. A central element to this work is Berkeley Lab’s U.S. State Renewables Portfolio & Clean Electricity Standards, an annual report published in slide-deck form that describes key trends, including recent legislative revisions, policy design features, past and projected impacts on clean electricity development, compliance with interim targets, and compliance costs.
Data files associated with several elements of this report are also available for download and are updated periodically:
- RPS & CES Demand Projections (XLSX) (last updated June 2023)
- RPS & CES Nominal Percentage Targets (XLSX) (last updated June 2023)
- Retail Electricity Sales Projections (XLXS) (last updated June 2023)
In addition to the annual status report, Berkeley Lab also conducts topical analyses of RPS- and CES-related issues, including past work evaluating the costs and benefits of state RPS policies. Drawing on this varied body of work, Berkeley Lab staff routinely provide briefings on RPS policies to state policy-makers, renewable energy stakeholders, and others.
