Site Approval No. PA-2200137

The Project would involve grading of the project site for the new construction and operation of a 400-megawatt battery energy storage system to provide reliable and flexible power to the local electrical system. The Project would interconnect at the Tesla Substation immediately adjacent to the site in Alameda County via a 230-kilovolt interconnection generation tie (gen-tie) line. The energy storage facility is anticipated to house lithium-ion batteries totaling 400 megawatts of energy. Project construction would begin in 2024 and is anticipated to come online in 2025. The Project would contain pad-mounted energy storage units, in addition to inverters, supervisory control and data acquisition (SCADA) equipment, a collector substation, and an interconnection gen-tie line to the Tesla Substation. The Project would also include related and supporting facilities such as on-site service roads, gates, security fencing, and temporary laydown and construction areas. The Project seeks the following entitlements/approvals from San Joaquin County: • Site Approval (application number PA-2200137) • Williamson Act Cancellation
