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 1.9 percent in 2014. More detailed information can be found in the 2014 Partnership Report (PDF) (15 pp, 2.64MB).
