Snohomish PUD to deploy 1 MW battery energy storage system

Snohomish County Public Utility District (PUD), 1Energy Systems and LG Chem announced that LG Chem will supply a 1 MW, 500 kWh advanced battery energy storage system as a core component of the MESA-1 energy storage system.

The MESA-1 system, to be deployed at a PUD substation later this in 2014, will be built on Modular Energy Storage Architecture (MESA).

Unlike conventional energy storage systems, MESA provides a standard, non-proprietary, scalable approach to energy storage in which electric utilities or grid operators can choose interoperable components — batteries, power converters and software — to meet specific needs and use cases. 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 utility-scale storage solutions are built on the technology, constant innovation, and extensive field validation of the company’s consumer and automotive battery businesses. This selection by the PUD and 1Energy Systems expands LG Chem’s presence in the U.S. following award of the 32 MWh Tehachapi Wind Storage Project in California in 2013.

The MESA-1 Project, announced in late 2012, also includes partners: Parker Hannifin, provider of the MESA-compliant 890GTB power conversion system (PCS); Alstom Grid, making its control center software platforms MESA-compatible; and University of Washington faculty, providing research expertise in electric power systems and computer science.
