Dive Brief:

• Eos Energy Storage has formed a partnership with Siemens to integrate, install and service energy storage solutions.

• The partnership will combine Eos’ 1-MW, 4-MWh battery system with Siemens power conversion and control systems that will enable modular installation of the batteries.

• The partners aim to offer storage solutions to the grid-connected and off-grid markets, and say they have several projects lined up for the first half of this year in California.

Dive Insight:

Large corporations are taking a growing interest in energy storage.

In aggregate, corporations invested nearly $660 million in storage in third-quarter 2016, a five-fold increase from third quarter 2015, according to the U.S. Energy Storage Monitor from GTM Research and the Energy Storage Association.

Large corporations are also partnering with smaller energy storage companies to leverage their capabilities.

“By combining Eos’ cost and performance advantage with Siemens’ capabilities in system integration and project execution, we are able to offer solutions that reduce risk and complexity for the customer while setting a new benchmark for energy storage reliability and cost-effectiveness,” Michael Oster, Eos’ CEO said in a statement.

The partners says they are testing storage systems that are setting the stage for MW-scale installations in the first half of 2017, including a California Energy Commission funded project with Pacific Gas and Electric and a behind-the-meter project at the University of California, San Diego.
