          - [Project No. 14642-002]

                    On May 1, 2018, the San Diego County Water Authority and the City of San Diego, California, jointly filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the San Vicente Energy Storage Facility, to be located at San Vicente reservoir, in Lakeside, California. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.                          ( print page 31748)    

The proposed project would consist of an integration of existing facilities and the construction of new facilities:

The lower reservoir portion of the proposed project would consist of the following: (1) The existing San Vicente reservoir with a storage capacity of 246,000 acre-feet and a surface area of 1,600 acres at a normal maximum operating elevation of 766 feet above mean sea level (msl); (2) the existing 1,430-foot-long, 337-foot-high San Vicente roller compacted concrete (RCC) gravity dam; (3) a lower reservoir inlet/outlet structure equipped with trash racks and either one or two slide gates; (4) a new 230-kilovolt (kV) substation containing step-up transformers, circuit breakers, and disconnect switches; (5) a new switchyard constructed at the point of interconnection at the western edge of San Vicente Reservoir; (6) an approximately 5-mile-long, 230-kV overhead or underground transmission line that would extend from the northern end of San Vicente reservoir to the 230-kV Sycamore substation and interconnect with San Diego Gas and Electric's existing 500-kV Sunrise Powerlink; and (7) appurtenant facilities.

The upper reservoir portion of the proposed project would be constructed near Foster Canyon, approximately one-half mile northwest of the San Vicente reservoir and would consist of: (1) A reservoir with a storage capacity of 7,842 acre-feet and a surface area of 100 acres at a full pond elevation of 1,490 feet msl; (2) five RCC saddle dams impounding the reservoir and measuring, respectively: (i) 1,425 feet long and 230 feet high, (ii) 838 feet long and 80 feet high, (iii) 838 feet long and 80 feet high, (iv) 1,006 feet long and 240 feet high, and (v) 3,100 feet long and 30 feet high; (3) an upper reservoir inlet/outlet structure; (4) a 2,050-foot-long, 22-foot-diameter power tunnel transitioning into two 326-foot-long, steel-lined penstocks extending between the upper reservoir inlet/outlet and the pump/turbines below; (5) a 360-foot-long, 83-foot-wide, 119-foot-tall subsurface powerhouse containing four 125-megawatt vertical Francis variable speed reversible pump/turbine/generator units; (6) a 2,244-foot-long, 25-foot-diameter concrete-lined tailrace tunnel connecting the pump-turbine draft tubes to the lower reservoir inlet/outlet structure; (7) a 2,200-foot-long, 230-kV, underground transmission line extending from the upper reservoir to the northern end of San Vicente reservoir; and (7) appurtenant facilities.

The project would generate an estimated 1,300 gigawatt hours annually.
