Two New Partners Join MESA-1 Energy Storage Project

Mitsubishi International Corp. will provide the first battery deployed in the MESA-1 energy storage project. The 1-MW, 500-kWh advanced battery storage system will be installed at Snohomish County Public Utility District’s Hardeson substation in Everett, Washington, U.S., later this year.

The MESA-1 installation will be the first energy storage system built on the Modular Energy Storage Architecture (MESA), an innovative approach to energy storage based on open, non-proprietary industry standards.

Mitsubishi International has delivered the advanced technology lithium-ion battery modules to Parker Hannifin Corp.’s Energy Grid Tie division, which will supply the power inverter and system housing. The battery modules contain battery cells manufactured by Lithium Energy Japan, a joint venture between GS Yuasa International Ltd. and Mitsubishi Corp. 1Energy Systems, LLC, located in Seattle, Washington, will supply advanced MESA-compliant system control software and integrate the complete energy storage system.

The lithium-ion battery equipment will be installed into a 40-ft (12-m) ISO shipping container. This modular system design allows for multiple containers to be combined into larger systems so customers can size energy storage systems for their specific needs without incurring the additional engineering costs of custom designed systems.
