Electric Program Investment Charge - EPIC
Partnered with the California Energy Commission (CEC), Eos Energy Storage (Eos) was awarded grant “EPC-18-023” to implement and demonstrate their Gen 2.3 Battery Energy Storage System in a commercial application. This installation consisted of (1) singular Eos Gen 2.3 Energy BlockTM rated for 125kW / 500kWh at a 4-hour energy discharge system. The system was installed and became commercially operational at the end of 2021.
This project showcased Eos’ technology as an alternative to battery storage systems, such as lithium-ion. The technology uses a zinc aqueous electrolyte manufactured and designed for a long-term duration and non-flammable energy storage system. This technology is the first zinc aqueous electrolyte battery to be used commercially and is a stepping stone in the industry to provide longer-term energy.
This grant provided by the CEC allowed Eos to install its technology and gather data through different testing procedures. Eos then gathered, analyzed, and used this data to help advance its technology for itself and its stakeholders.
