Specified Source Facilities - Registration by February 1

By February 1 of each year, Electric Power Entities (EPE) are required to register anticipated specified sources of power that they intend to claim in June 1 filings, pursuant to section 95111(g)(1) of the Mandatory Reporting Regulation (MRR).  ARB will use this information to calculate emission factors for the specified sources submitted which will be used by EPEs in their June 1 emissions data reports.  

Registration of sources anticipated to be claimed for the RPS adjustment is not required, but should be included with the June 1 emissions data report.  

The link below provides the spreadsheet template for registering specified facilities as required by section 95111(g) of the GHG Mandatory Reporting Regulation.  Please email the completed spreadsheet by the February 1st deadline to with the subject line: “Registration of Specified Electricity Import and Export Sources.”
