About

The Antelope Solar 2 project is a proposed 781.88 MW hybrid solar and battery energy storage project located in Los Angeles County, California. The development project consists of a 423 MW solar array coupled with a 358.88 MW battery energy storage system. It is interconnected to Southern California Edison (SCE) via the Antelope Substation 220kV.

The project is listed in the CAISO interconnection queue as entry CAISO-1208, with a queue entry date of April 30, 2015, and a proposed commercial operation date of November 27, 2025. An Interconnection Agreement (IA) was executed on May 8, 2019. The Antelope Solar 2 project has been featured in recent industry news.

Development Risk

Realization risk from now to commercial operation — financing close, EPC and tax-equity counterparty mix, and COD probability vs the proposed date. The diligence view that determines whether the deal actually closes. Powered by InfraSure's development-stage modeling stack.
