The proposed HUMMINGBIRD ENERGY STORAGE project is a 75 MW battery storage development in Santa Clara County, California. Interconnection is being managed through the CAISO queue (queue ID CAISO-1454), with an entry date of April 16, 2018, and a proposed commercial operation date of September 25, 2025. The interconnection agreement for the project was executed on April 15, 2021. The point of interconnection is the Metcalf 115 kV substation.
The project is linked to the existing Hummingbird Energy Storage LLC operating plant (EIA plant ID 65395). The HUMMINGBIRD ENERGY STORAGE project has been mentioned in recent news coverage.
