The Federal Energy Regulatory Commission on June 26 accepted a Co-Tenancy and Shared Use Agreement among CSOLAR IV South LLC, Imperial Valley Solar 1 LLC (IVS-1) and Imperial Valley Solar LLC (IVS) (collectively called the Co-Tenants).
On May 28, CSOLAR IV South had filed this agreement with the commission. CSOLAR is an exempt wholesale generator and is authorized to sell power at market-based rates. CSOLAR is owned by Tenaska CSOLAR South Holdings LLC (99%) and Tenaska CSOLAR South LLC (1%).
CSOLAR owns and is developing the first phase of the Imperial Solar Energy Center Project (CSOLAR South Project), a ground-mounted photovoltaic system to be located in El Centro, Calif. The 130 MW output of the CSOLAR South Project is fully subscribed under a 25-year power purchase agreement with San Diego Gas & Electric (SDG&E). The CSOLAR South Project will interconnect to transmission facilities owned by SDG&E and operated by the California Independent System Operator (CAISO).
IVS-1, together with IVS, is developing the first phase of a 600-MW photovoltaic solar facility located in Imperial County (called the IVS Imperial Project). The IVS Imperial Project will interconnect to the CAISO-controlled grid at the Imperial Valley Substation, which is owned and operated by SDG&E. CSOLAR told FERC that the 200-MW first phase of the IVS Imperial Project, owned by IVS-1, is currently under construction, and subsequent phases to be owned by other Imperial Valley Solar companies will also be developed.
The Co-Tenancy Agreement provides for the shared construction, ownership, and use by the Co-Tenants of an above-ground 230-kV double circuit radial generator tie-line interconnection facility and related facilities for their respective solar facilities. CSOLAR said that both it and IVS-1 have closed financing on their respective solar facilities, and that IVS-1 will begin to use a portion of the shared facilities, under the terms and conditions of the instant agreement, for the first time beginning on or about July 1, 2013, when IVS-1 commences generating test power.
Imperial Valley Solar 2 LLC will own the 150-MW second phase of the IVS Imperial Project; Imperial Valley Solar 3 LLC will own the 150-MW third phase of the IVS Imperial Project; and Imperial Valley Solar 4 LLC will own the 100-MW fourth phase of the IVS Imperial Project.
