About

ELYSIAN is a proposed 412.18 MW hybrid solar and battery energy storage project located in Fresno County, California. The development project consists of 206.09 MW of solar photovoltaic generation paired with 206.09 MW of battery storage. It is in the California Independent System Operator (CAISO) interconnection queue as queue ID CAISO-1935, with an interconnection queue entry date of April 15, 2021. The project's proposed commercial operation date is October 18, 2029, and its interconnection agreement has been executed. The point of interconnection is the Tranquility 230 kV substation.

The project, which is in the Pacific Gas & Electric (PGAE) service area, has been featured in recent news coverage.

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.
