Blog | Ending the use of SF₆ in power grids | Eaton | UK

As electrical power distribution systems become more decentralized to integrate skyrocketing renewables, the demand for switchgear, and thus the use of SF 6, is expected to rise dramatically. Where we once had a few, centralized fossil fuel facilities, soon we will have many times more renewable solar arrays and wind turbines—each requiring their own set of switchgear.

Electricity Transmission and Distribution Greenhouse Gas

Sulfur hexafluoride is a commonly used insulator in electricity transmission and distribution equipment. Because of its high global warming potential (GWP), CARB adopted the Regulation for Reducing Sulfur Hexafluoride Emissions from Gas Insulated Switchgear in 2010. As new technologies using lower or zero GWP insulators emerge, CARB staff are proposing to amend the current regulation to further reduce greenhouse gas emissions and to increase flexibility in complying with the standards.
