sourceThe ROCCASECCA BESS project is a proposed 405 MW hybrid wind and battery energy storage system located in Clark County, Nevada. The development project, which has appeared in recent news coverage related to deals, consists of a 310 MW wind farm coupled with a 95 MW battery.
The project is listed in the CAISO interconnection queue as entry CAISO-1347, with an initial queue entry date of May 2, 2016. The proposed commercial operation date is March 1, 2027. An Interconnection Agreement (IA) has been executed with GLW, effective December 3, 2018. The point of interconnection is the Sloan Canyon Switching Station 230kV.
