About

The Grace Energy Center is a proposed 1017.12 MW hybrid solar and battery project located in Riverside County, California. The development project consists of 508.56 MW of solar generation and 508.56 MW of battery energy storage. Interconnection is being pursued through the CAISO queue under queue ID CAISO-1761, with an interconnection request date of April 15, 2020, and a proposed commercial operation date of January 13, 2027. The project has an executed Interconnection Agreement (IA) with Southern California Edison (SCE).

The Grace Energy Center has been the subject of recent news coverage, with 18 articles categorized as industry-related and regulatory.

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.
