About

The AZALEA project is a proposed 99.3 MW hybrid solar and battery energy storage project located in Kern County, California. The development project consists of a 61.3 MW solar array coupled with a 38 MW battery energy storage system. It is listed in the CAISO interconnection queue as project CAISO-1493, with an initial queue entry date of April 16, 2018, and a proposed commercial operation date of September 12, 2025. The interconnection point is Arco 70 kV, and the interconnecting utility is PG&E.

The project's interconnection agreement (IA) has been executed as of June 11, 2020. The AZALEA project has been the subject of recent news coverage, with nine articles appearing in industry and development publications.

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.
