Long-Duration Storage Projects Gaining Steam
Just days after the California Energy Commission announced the first application in the state for storage using compressed air, another long-term storage proposal advanced: a 500 MW project that would use pumped storage at the San Vicente Reservoir in eastern San Diego County.
The City of San Diego and the San Diego Water Authority board have begun negotiations with BHE Kiewit, a subsidiary of Berkshire Hathaway, on the financing and building terms for the estimated $1.5 billion pumped storage facility. The city and the water agency also approved two contracts totaling $6.2 million for an environmental impact analysis and for preparation of an interconnection agreement with the grid operator plus a license from the Federal Energy Regulatory Commission, all on Jan. 27.
