Jackson Prairie Underground Natural Gas Storage Facility
From Wikipedia, the free encyclopedia
Jackson Prairie Underground Natural Gas Storage Facility is a natural gas storage facility in Southwest Washington. The site is owned by Puget Sound Energy, Avista and Williams Companies's Northwest Pipeline GP.[1][2] With 25 billion cubic feet working capacity (47 billion cubic feet total capacity), it is the largest natural gas-storage reservoir in the Pacific Northwest and the 14th largest in the United States.[3][4]
Located in the community of Mary's Corner, Washington,[5] the gas storage is in an aquifer contained by the sandstone Skookumchuck formation, about 1,000 to 3,000 feet underground.[6][7][8]: Slide 4
