Beginning January 1, 2028, all retail electricity suppliers must annually report to the Energy Commission their electricity sources used to serve load, associated greenhouse gas emissions, annual total emissions, emissions intensity, and avoided emissions for the previous calendar year.

The Energy Commission must adopt rules by July 1, 2024 to implement reporting requirements, and shall annually publish aggregated summaries of reported data on its website while sharing information with the Public Utilities Commission, State Air Resources Board, and the Independent System Operator as needed.

Sellers of electricity from generation facilities, energy storage facilities, and entities allocating electricity from specified sources must timely provide hourly data on electricity shares and associated greenhouse gas emissions to purchasers subject to reporting requirements.

The Public Utilities Commission must calculate and publish annually the percentage of each load-serving entity's resource adequacy requirements met through eligible renewable energy, zero-carbon resources, or energy storage resources from the previous calendar year.

The Public Utilities Commission and local publicly owned electric utility governing boards must review reported annual greenhouse gas emissions and emissions intensity to assess whether entities are making adequate progress toward established greenhouse gas reduction targets.
