Princeton, N.J.-based Princeton Power Systems said on Dec. 1 that it completed delivery of the latest generation of its 100 kW grid-tied inverters for an energy storage project in Boothbay, Maine.
Lockheed Martin’s 3 MWh energy storage system, which was launched by Convergent Energy + Power, is part of a program to study the use of non-transmission alternatives in the Boothbay area to avoid or defer infrastructure upgrades.
“This is a groundbreaking project that uses a location-specific, third-party owned and operated energy storage asset to defer a far more expensive upgrade to the traditional transmission and distribution system,” Convergent CEO Johannes Rittershausen said in a Dec. 1 statement. “The Boothbay project demonstrates that the electricity grid can be improved and made more reliable in a clean, efficient way – while saving electricity users money.”
PPS said that its GTIB-100 G1.2 inverter was chosen for its energy storage integration features for the project in the Boothbay region. According to the company, the inverter is the world’s first UL-1741 safety standards certified commercial-scale microgrid converter. The technology is a three-phase 100 kW four-quadrant converter with advanced microgrid functions, designed for batteries, solar, on-grid and off-grid applications.
The 3 MWh energy storage system was designed to alleviating peak summer power reliability issues in the Boothbay area.
“As distributed energy storage performance has improved, and costs have come down, it is becoming a viable solution to a wide variety of efficiency and reliability concerns on the electric grid,” Darren Hammell, co-founder and chief strategy officer at PPS, said in a statement. “Advanced power electronics and controls software are critical pieces of a highly-functional energy storage solution.”
