Specified Source Facilities - Registration by February 1

By February 1, 2017, EPEs must register their anticipated specified sources of power that they intend to claim in their 2016 Emissions Data Reports pursuant to section 95111(g)(1) of the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR). 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, 2017, as well as new and existing anticipated specified sources for asset-controlling suppliers (ACS).

ARB will use this information to calculate an emissions factor for each specified source. The emission factors will be published on ARB’s website and made available to reporting entities in Workbook 1. 

The link below provides the Specified Source Facilities Workbook. Completed Specified Source Facilities Workbooks must be emailed to with the subject line:  “Specified Source Registration – [company name and/or acronym]” by the February 1, 2017, deadline
