PGE Phases Out sf 6 Greenhouse Gas | TD World

Like carbon dioxide, SF 6 is a greenhouse gas. While CO 2 has a global warming potential (GWP) of one, SF 6 has a GWP of 23,500. Although PGE reduced its SF 6 leak rate to nearly 1%, this came with an extreme operating cost. Eliminating the use of SF 6 would eliminate future leaks and result in reduced operating cost.
