The SF6 Emission Reduction Partnership for Electric Power Systems is a collaborative effort between EPA and the electric power industry to identify and implement cost-effective solutions to reduce sulfur hexafluoride (SF6) emissions. SF6 is a highly potent greenhouse gas used in the industry for insulation and current interruption in electric transmission and distribution equipment. Currently 84 utilities participate in this voluntary program.

Established in 1999, the Partnership has been effective at reducing the SF6 emission rate from the Electric Power Industry. The Partnership’s SF6 emission rate has dropped from 14 percent in 1999 to 2.2 percent in 2012. More detailed information can be found in the 2013 Partnership Report.

As of 2011, mandatory emissions reporting is required for users of electrical transmission and distribution (T&D) equipment with nameplate capacity over 17,820 lbs (subpart DD of the 40 CFR Part 98). See the GGRP homepage for more information.

The SF6 Emission Reduction Partnership for Electric Power Systems continues with its mission to identify and implement cost-effective methods for reducing SF6 emissions from electrical T&D equipment. The Partnership provides a forum for Partners to share best practices on methods to track SF6 gas flows and training and resources to support the objective of accurately estimating SF6 emissions.

Please visit the Reporting page of the Partnership website for more information.
