The California Energy Commission staff has issued a revised staff paper for implementation of new Power Source Disclosure (“PSD”) program requirements that were added by Assembly Bill (“AB”) 1110 in 2016. AB 1110 amended the program by requiring suppliers to also report and disclose the greenhouse gas (“GHG”) emission intensities and the unbundled renewable energy credits (“REC”) associated with their retail sales.
The staff’s paper, Revised Assembly Bill 1110 Implementation Proposal for Power Source Disclosure, is part of the pre-rulemaking process for AB 1110 implementation (Docket No. 16-OIR-05). The Energy Commission expects to commence a formal rulemaking in late 2018, which will introduce proposed regulatory language and commence the statutorily mandated one year deadline to conclude the rulemaking.
PSD Program Changes to Accommodate GHG Emissions Intensity
The GHG emissions intensity, or emissions factor, is the rate of GHG emissions that results from one megawatt of generation. AB 1110 requires GHG emissions intensity to be reported on Power Content Labels starting 2020, meaning data will be reported for 2019 retail sales. The Energy Commission has developed its GHG intensity proposal in consultation with the California Air Resources Board (“CARB”), and is making efforts for consistency with that agency’s Mandatory Reporting Regulation (“MRR”) for GHG emissions.
Proposed PSD program changes to accommodate reporting of GHG emissions intensity includes the following:
Proposed Treatment of RECs and Unbundled RECs
The Renewable Portfolio Standard program has a multiyear compliance period that allows retail suppliers to retire RECs up to 36-months from the generation date. The revised staff paper differentiates this program from the PSD program’s required annual reporting of an electric portfolio’s eligible renewable electricity. As such, the staff paper states that electricity from renewable energy sources should be reported according to the year it was generated, and these transactions only count if the REC and electricity were transacted together. Additionally, staff proposes that RECs will not be used to track or reduce GHG emissions. Unbundled RECs may not be classified as renewable energy in the PSD power mix, but suppliers can disclose their retired, unbundled RECs as a percentage of retail sales in a footnote on the Power Content Label.
A workshop is scheduled for February 1 and written comments are due February 23. Please contact Brian Biering if you have any concerns regarding AB 1110 implementation or are interested in assistance participating in the Energy Commission’s stakeholder processes.
