The Federal Energy Regulatory Commission on Nov. 20 accepted a filing on Oct. 16 by Southern California Edison (SoCal Edison) of an amended large generator interconnection agreement (LGIA) for a 500-MW solar project in California.
The amended LGIA is with NextEra Desert Center Blythe LLC and the California Independent System Operator (CAISO). It provides the terms and conditions under which SoCal Edison will construct, own and operate the interconnection facilities required to interconnect NextEra’s proposed 500-MW Genesis McCoy solar facility to SoCal Edison’s planned Colorado 220-kV substation.
Under a 2011 orginal LGIA, SoCal Edison, NextEra Desert Center and CAISO agreed to various terms, including a transmission path that would only allow Full Capacity Deliverability Status for the project in early 2019, at the earliest.
But then NextEra Desert Center asked for interim grid fixes that would push that full capacity status up to mid 2013. The fixes include the temporary installation of series reactor banks on SoCal Edison’s four existing 220 kV transmission lines out of the Devers substation. These fixes would be in place until the permanent grid upgrades are completed. The amended LGIA includes costs and charges for these temporary fixes.
