Eos Energy Storage & Northern Power to supply integrated battery storage solutions


Eos and Northern Power initiated the partnership focusing on development and optimization in 2016, and plan to deliver fully-integrated products to major utilities in the second quarter of 2017.

The initiative combines the Eos Aurora DC battery system with Northern Power’s advanced energy storage inverter, controls, and engineering expertise. The suite of integrated solutions provides four hours of usable energy using modular 250kW battery building blocks that are scalable for multi-MW applications.

Eos Aurora Znyth battery solution is powered by an aqueous, zinc hybrid cathode technology and available at a volume price of $160/kWh for the DC system, which includes an expected life of 5,000 full depth-of-discharge cycles.

Northern Power’s FlexPhase power converter technology leverages a modular, compact, and efficient design that is easy to service. The platform allows for a wide range of DC voltages suitable for a variety of battery types. The company’s proprietary PowerRouterTM controls allow for seamless transitions between grid and islanded operation, as well as black start capability.

“Batteries represent a significant portion of the performance and cost of an energy storage system,” said Chris McKay, Director of Sales at Northern Power Systems. “By using the Eos Aurora, we can deliver a fully integrated ESS solution at an all-in, installed price of less than $400/kWh — depending on project size and location but always with the quality, functionality and reliability that is characteristic of Northern Power.”

Northern Power and Eos are jointly developing and supplying industry-leading, turnkey ESS solutions offering seamless integration of batteries, power conversion, and controls along with installation and maintenance services as needed. The joint product represents a cost-effective option for utilities who want to provide relief in grid constrained areas, lower capacity payments, defer substation upgrades, and/or better integrate renewable energy. The integrated product is also appropriate for large commercial and industrial facilities looking to lower demand and peak energy charges, or provide resiliency against grid outages.

“Northern Power’s patented converter architecture and advanced controls technology are an excellent match for Eos’ battery offering. The team’s engineering capabilities will ensure successful system integration and performance for major utilities around the world,” said Eos Vice President of Business Development, Philippe Bouchard. “We are gratified to work on these projects with Northern and their clients, and Eos looks forward to deepening this relationship through the collaborative Eos Aegis integration program.”
