NEW YORK -- April 30, 2013

Eos Energy Storage and Con Edison, a subsidiary of Consolidated Edison, Inc.
(NYSE: ED), today announced a trailblazing partnership to install and test
Eos’s cutting-edge energy storage technology within the utility’s New York
City facilities. Eos is currently commercializing a safe, low cost, and
long-lasting grid-scale battery technology that can reduce customer costs,
defer utility infrastructure upgrades and enhance power quality and
reliability.

Supported by funding from the New York State Energy Research and Development
Authority (NYSERDA), the pilot will demonstrate the benefits of distributed
energy storage.

“Through this pilot and partnership with Con Edison, we have the opportunity
to install our safe, efficient battery technology in a dense load center like
New York City, where the benefits of energy storage are particularly
significant,” said Eos President Steve Hellman.

Eos stated that the pilot, targeted to begin in early 2014, is a milestone in
the scale-up and commercialization of Eos’s core product, a 1MW/6MWh
grid-scale battery called the Eos Aurora. The Aurora is backed by Eos’s novel,
low-cost and proprietary zinc hybrid cathode technology, which has a 75%
round-trip efficiency rate and a 10,000-cycle/30-year lifetime.

“Our belief is that affordable energy storage will improve the efficiency and
resilience of the electricity grid while reducing costs for utilities and
customers alike, and it is a great opportunity to prove this together with a
pre-eminent utility like Con Edison.” Eos CEO Michael Oster said.

“Con Edison looks forward to installing and measuring Eos’s new battery. As
pioneers in the delivery of electricity, Con Edison sees the potential of
another pioneer, which is why the company is working with Eos,” said Troy
Devries, Con Edison’s director of Research and Development. “Energy storage is
one of the last frontiers for electric utilities and Eos Energy Storage holds
promise for smooth integration.”
