NEC Energy Solutions is supplying its first lithium-ion grid energy storage pilot system GSS® to Southern California Edison (SCE).
The deal with the NEC Corporation subsidiary comes under a pre-approved energy storage procurement program initially announced by SCE last year.
The solution product line is the first in the ‘plug-and-play’ procurement strategy being employed by SCE.
GSS® includes 3.4MWh of containerised lithium-ion batteries, a 3MW power conversion system, and NEC ES’s proprietary AEROS® controls software suite.
It enables renewable integration, T&D support and peak shaving to support grid reliability.
The Grid Battery System, the heart of the GSS, contains energy storage system, a battery management system, and the controls.
The power AC/DC conversion system is an integral part of the GSS®.
The ESS will be installed to defer traditional distribution grid upgrades that are becoming increasingly challenging in dense urban environments.
Bud Collins, CEO, NEC ES, said: “Commercialiation of energy storage in a way that allows quick and easy procurement has always been a goal of ours.”
