About

Briggs Storage is a proposed 70.39 MW battery storage project in Haskell County, Texas. The project, developed by Briggs Solar, LLC, is located within the ERCOT region and consists entirely of battery storage. It is listed in the ERCOT interconnection queue as entry ERCOT-24INR0058, with a queue entry date of May 31, 2021, and a proposed commercial operation date of April 15, 2028. The project's interconnection status is currently in the Facility Study phase.

The proposed project's point of interconnection (POI) is on the tap 345kV 60515 Clear Crossing - 60507 Pendulo line. Briggs Storage has been mentioned 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.
