On January 23, 2015, Puget Sound Energy (PSE) announced it will deploy a 2MW/4.4MWh energy storage system utilizing lithium-ion batteries, designed to MESA’s set of open standards.

Excerpts from PSE’s press release included below:

The first battery system PSE will deploy is being designed to the Modular Energy Storage Architecture (MESA) set of open standards for energy storage. MESA is an association of electric utilities and energy storage vendors based in California whose mission is to define and promote the use of open standards in the creation of energy storage systems.

The system will use 1Energy’s Intelligent Controller™ software to demonstrate several core use cases such as shaving peaks in demand, grid flexibility, and backup power.

“Having PSE’s leadership on this issue will certainly inspire others and give our efforts more momentum,” said Darcy Wheeles, Program Director for the MESA Standards Alliance.
