FERC accepts interconnect deal for repowered, 30-MW Sunray facility in California

The Federal Energy Regulatory Commission on Feb. 10 accepted Southern California Edison‘s Jan. 6 filing of a Large Generator Interconnection Agreement with Sunray Energy LLC and the California Independent System Operator that is needed due to a planned repower of a Sunray solar facility.

Sunray owns and operates a 30 MW (net) solar thermal, parabolic trough facility named the SEGS II Project, located in Daggett, California. The SEGS II Project is an existing interconnected generation resource interconnected to SCE’s transmission system via a tap on the Coolwater-Tortilla 115-kV line.

Sunray has been selling the capacity and energy produced by the project entirely to Southern California Edison under a power purchase agreement (PPA) subject to the jurisdiction of the California Public Utilities Commission, dating back to 1984. The PPA includes an interconnection facilities agreement. The parties agreed to terminate the PPA effective at midnight on Dec. 31, 2015, and to establish interconnection arrangements under the LGIA.

Sunray plans to replace the existing solar thermal technology and steam-turbine generator with inverter-based photovoltaic technology. The repowered facility is due for commercial operation around Nov. 1 of this year.

Said the LGIA in describing the revamped facility: “Following the completion of the Repower, the Large Generating Facility will be a 30 net MW, (33.6 gross MW) solar photovoltaic generating facility located at 35100 Santa Fe Street, Daggett, California, as disclosed by the Interconnection Customer, which consists of (i) forty-two (42) SMA Sunny Central 800CP-US 800kVA inverters (ii) the associated infrastructure (iv) meters and metering equipment, and (v) appurtenant equipment. Capacity at the Point of Interconnection for Interconnection Service will be 30 MW incurred on the Tortilla-SEGS II- Coolwater 115 kV Transimission Line.”
