Eos Energy Storage, a US-based grid-scale battery technology, has raised $15m in its series B round from a syndicate of 21 strategic and financial investors, including energy utility NRG Energy and real estate developer Fisher Brothers.
Eos is NRG’s first investment in the energy storage industry and the portfolio company will begin deploying its Aurora product next year as the portfolio company said it was “in advanced discussions with several states regarding the location of its pilot manufacturing facilities”.
Denise Wilson, president of new businesses at NRG, which is also a limited partner in the Energy Technology Ventures fund managed by General Electric, said: “Eos’s technology is of strategic interest to NRG as we seek to enhance the value of our generation assets and evaluate novel energy storage business opportunities.”
Winston Fisher, a partner at Fisher Brothers, added: “Energy storage can bring building operations and the electricity grid into the 21st century. Eos’s groundbreaking technology will reduce costs for building owners and help integrate renewable energy on the grid.”
Fisher Brothers owns New York City-based Plaza Construction, a contractor with experience building urban power plants and renewable energy projects.
Fisher Brothers is also a co-sponsor of the City Investment Fund (with Morgan Stanley), a founding member of Perella Weinberg Partners and a founding partner of Convergent Energy + Power, an energy storage asset development company with a pipeline of projects in New York, California and elsewhere.
