Snohomish County Public Utility District, 1Energy Systems and LG Chem successfully commissioned a 1 MW, 500 kWh advanced battery energy storage system as a core component of the MESA-1 energy storage system.
The MESA-1B energy storage system is installed at the PUD’s Hardeson Substation and is built on the modular energy storage architecture (MESA) Standards Alliance communication standards.
The MESA Standards Alliance is developing non-proprietary communication standards that allow utilities or grid operators to choose interoperable components — batteries, power converters and software — to meet specific needs and use cases and implement a scalable approach to energy storage. The ability to exchange components also makes it easier and more cost effective for utilities or other customers to upgrade or replace components as new technologies emerge.
LG Chem’s energy storage solutions have been deployed worldwide for grid-scale, commercial & industrial and residential applications and are built on the technology, constant innovation and extensive field validation of the company’s overall energy solution business, which also includes battery products for consumer electronics and vehicle applications.
The MESA-1B Project, announced in 2014, also includes partners: Parker Hannifin, provider of the MESA-compliant 890GTB power conversion system (PCS); Alstom Grid, making its e-Terra control center software platforms MESA-compatible; and University of Washington faculty, providing research expertise in electric power systems and computer science.
The PUD project was made possible in part by a $7.3 million investment from the Washington State Clean Energy Fund. The Washington State Department of Commerce awarded more than $14 million in grants for demonstration projects that will help utilities better integrate intermittent renewable electricity, increase the efficiency of their systems and improve grid reliability.
