4 MWh Sale to California PV + Storage project

California Energy Commission-funded Invinity VS3 batteries to provide on-demand solar power for Rincon Band of Luiseño Indians in Southern California

Invinity Energy Systems plc (AIM: IES) (AQSE: IES) (OTCQX: IESVF), a leading global manufacturer of utility-grade energy storage, is pleased to announce a 4 MWh sale to PowerFlex, part of EDF Renewables North America. The batteries will be used in a California Energy Commission-funded solar microgrid project being undertaken by the Rincon Band of Luiseño Indians.

The project will see 18 Invinity VS3 vanadium flow batteries, with a combined capacity of 4 MWh, installed by PowerFlex alongside a new 1 MWp expansion to the existing PV solar array at the Rincon Band's Harrah's Resort Southern California at the Rincon Reservation near Valley Center, California, as part of a large-scale solar microgrid project. Invinity's batteries will be used to store excess solar generation which can be discharged on-demand to provide economic, low-carbon power to the site at any time of the day or night.

California is one of the world's fastest growing battery markets and, with 7.3 GW, has the most installed battery capacity of any U.S. state. The California Energy Commission is also one of the leading funders of non-lithium-ion long duration energy storage (LDES), having already provided support worth $140m to various projects in the State throughout 2022-23 and has $190m worth of funding programmed for in the 2023-24 State Budget. The State is targeting 52 GW of battery storage capacity by 2045.

Delivery of the Invinity batteries is expected to occur before the end of 2024. The contract was included as part of the Company's Base category in its most recently disclosed commercial pipeline.
