CSOLAR IV to share interconnect for its 130-MW project

CSOLAR IV South LLC on May 28 filed with the Federal Energy Regulatory Commission various documents, including a Co-Tenancy and Shared Use Agreement, related to its nearly-completed solar project in California.

The agreement, which is among CSOLAR, Imperial Valley Solar 1 LLC (IVS-1), and Imperial Valley Solar LLC (IVS), provides for the shared construction, ownership, and use by these companies of an above-ground 230-kV double circuit radial generator tie-line interconnection facility and related facilities for their respective solar photovoltaic facilities. The filing noted that the IVS-1 facility is scheduled to generate first electricity on or around July 1, 2013.

CSOLAR is owned by Tenaska CSOLAR South Holdings LLC (99%) and Tenaska CSOLAR South LLC (1%). Tenaska CSOLAR South is a wholly owned subsidiary of Tenaska Energy, an independent developer and owner of power production facilities located throughout the United States and abroad.

CSOLAR owns and is developing Phase I of the Imperial Solar Energy Center Project (called the “South Project”), a ground-mounted photovoltaic system to be located in El Centro, Calif. Phase I of the South Project, to be completed in 2013, is under construction and will have a capacity of approximately 130 MW. The full 130 MW of the South Project’s output is committed under a 25-year power purchase agreement with San Diego Gas & Electric (SDG&E). CSOLAR will be interconnected with transmission facilities owned by SDG&E and under the operational control of the California Independent System Operator (CAISO). CSOLAR is an exempt wholesale generator (EWG) and is authorized to sell power at market-based rates.

Phase II of the Imperial Solar Energy Center Project (called the “East Project”) is a 70-MW ground-mounted photovoltaic system that is in the advanced stage of development by CSOLAR’s affiliate Wistaria Ranch Solar LLC, with commercial operation targeted for 2016. Interconnection of the South Project and the East Project is governed by a non-conforming Large Generator Interconnection Agreement (LGIA) among the CAISO, SDG&E, CSOLAR, Wistaria, and Tenaska Solar Management LLC.

IVS-1, together with IVS, Imperial Valley Solar 2 LLC, Imperial Valley Solar 3 LLC and Imperial Valley Solar 4 LLC are developing a photovoltaic facility, located in Imperial County, Calif., with a combined capacity of 600 MW. These companies will own a phase of the IVS Project as follows: 200 MW Phase 1 to be owned by IVS-1, and now under construction; 150 MW Phase 2 to be owned by IVS-2; 150 MW Phase 3 to be owned by IVS-3; and 100 MW Phase 4 to be owned by IVS-4.
