PacifiCorp-687 is a proposed energy storage project located in Klamath County, Oregon. The project, under development by Swan Lake North Hydro, LLC, is a 415.8 MW battery storage facility utilizing "Other Storage" technology. Interconnection is planned with PacifiCorp's Malin 500 kV substation.
The project is in the PacifiCorp interconnection queue with an entry date of July 28, 2015. The proposed commercial operation date was December 31, 2022, but the interconnection agreement status is currently listed as "Suspended". The project has been mentioned in recent news coverage related to development.
