Sempra seeks rate authority for Copper Mountain Solar 4 project

Copper Mountain Solar 4 LLC applied April 1 at the Federal Energy Regulatory Commission for acceptance of its Market-Based Rate Tariff and the granting of certain blanket approvals.

Applicant is a wholly-owned direct subsidiary of Sempra Solar Holdings LLC, which in turn is a wholly-owned direct subsidiary of Sempra Renewables LLC, which in turn is a wholly-owned direct subsidiary of Sempra Global, which in turn is a wholly-owned direct subsidiary of Sempra Energy.

The company is constructing and will own and operate a solar photovoltaic (PV) facility near Boulder City, Nevada, with a nameplate capacity of 93.6 MW, located in the California ISO balancing authority area (BAA). The facility also includes certain interconnection facilities, consisting of a 34.5/230 kV collector substation and a 230kV generator tie line approximately 0.5 mile in length, used for the sole purpose of connecting the facility to the CAISO-controlled grid.

Applicant will sell the entire output of the facility pursuant to a 20-year power purchase agreement (PPA) commencing Jan. 1, 2020, with the Southern California Edison Company. The project is due in-service this year.
