EPE Emissions Data Reporting
Submission by June 1; Verification by August 10
By midnight Pacific Time on June 1 of each year, EPEs, including asset-controlling suppliers (ACS) and multi-jurisdictional retail providers (MJRP), must submit an emissions data report pursuant to section 95103(e) of the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR) via the Cal e‑GGRT reporting system. The June 1 emissions data report includes reportable transaction and emissions for the previous calendar year. Please contact CARB if you believe you might be subject to reporting, and/or need to setup an account for reporting.
EPEs report data using Excel-based forms that provide for all the reporting requirements in accordance with the current MRR. CARB updates the reporting workbooks every year and only the most up-to-date version of the workbooks will be accepted by Cal e-GGRT for upload and reporting.

Specified Source Registration
Registration by February 1
By February 1 of each year, EPEs must register their anticipated specified sources of power that they intend to claim in their June 1 Emissions Data Reports pursuant to §95111(g)(1) of the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR). The June 1 Emissions Data Reports cover emissions for the previous calendar year. All specified sources associated with imported power, exported power, or power used to claim an RPS adjustment, including any zero emission resources, must be registered by February 1, as well as new and existing anticipated specified sources for asset-controlling suppliers (ACS).
CARB will use this information to calculate an emission factor for each specified source. The emission factors will be published on the CARB website and made available to reporting entities in the respective reporting workbooks.
The link below provides the Specified Source Registration Workbook (SSR). Completed SSRs must be emailed to email@example.com with the subject line: “Specified Source Registration – [company name and/or acronym]” by the February 1 deadline.
