Southern California Ed files revised interconnect deal for 40-MW solar project

Southern California Edison on Aug. 8 filed with the Federal Energy Regulatory Commission a revised Clustering Large Generator Interconnection Agreement that had initially in 2014 been under one company, Windhub Solar LLC, for the Windhub Solar Project, with that project now split between two companies.

Windhub Solar LLC has assigned its entire interests in this agreement to Windhub Solar A LLC and Windhub Solar B LLC, as Co-Tenants. The agreement covers all equipment and facilities comprising the Windhub Solar generating facility in Kern County, California. The facility is to be interconnected to Southern California Edison’s Windhub Substation via the Windhub-Sunspot 66 kV Line. The solar facility has a total gross output of 41.62 MW as measured at the inverter terminals.

The project net output is 40.36 MW as measured on the high-side of the main transformer banks which takes into account the internal project losses of 1.26 MW. The facility will be required to limit output to not exceed 39.7 MW as measured at the high-side of main transformer banks in order to limit the capacity at the Point of Interconnection for interconnection service to 39.65 MW when taking into account the incremental generation tie-line losses of 0.36 MW on the shared Winhub-Sunspot 66 kV line. Collectively, the total capacity corresponding to the Windhub Solar Project will be 39.65 MW at the Point of Interconnection.

Under this revised deal the commercial operation target date has been changed from Oct. 31, 2016, to a new date of Feb. 1, 2018.
