PSE-54 is a proposed 198.8 MW gas-fired generation project located in Grays Harbor County, Washington. The project is being developed by Puget Sound Energy (PSE) and interconnected to the Olympia Substation. It entered the Puget Sound Energy interconnection queue on December 27, 2017, with a proposed commercial operation date of June 1, 2026.
The project's interconnection status is currently listed as "suspended," and its interconnection agreement (IA) status is also "suspended."
