  NEW YORK, June 15, 2011

NEW YORK, June 15, 2011 /PRNewswire/ -- Ener1, Inc. (NASDAQ: HEV) and the
Russian Federal Grid Company (FGC) (MICEX: FEES) today announced they will
display a fully operational, lithium-ion, distributed energy storage system as
part of the 15th annual St. Petersburg International Economic Forum which will
be held June 16-18 in Russia. The Forum will be attended by more than 2,500
people. Leading the roster of government leaders and corporate CEOs from
around the world are opening speeches by the President of the Russian
Federation, Dmitry Medvedev, and the President of the People's Republic of
China, Hu Jintao.

Ener1 and FGC will be displaying a 70 kWh distributed energy storage system.
While the unit is a smaller version of the large-scale solutions the
companies are co-developing as part of an agreement signed last November, it
will provide attendees an understanding of how the two companies can
strategically manage power storage for the country's electric grid. The
large-scale distributed energy storage systems being developed -- which will
be used for emergency back-up power at FGC substations in St. Petersburg and
the Black Sea port city of Sochi, site of the 2014 Winter Olympic Games -- are
scheduled to be installed in Russia in the next few months. The first unit
will be shipped in the next few weeks.

"Ener1 is committed to working with FGC as part of its effort to support
Russia's $15-billion investment to modernize the country's electric grid
infrastructure through 2012," said Ener1 Chairman and CEO Charles
Gassenheimer. "Together, we're developing energy storage solutions that we
hope will leap-frog the current infrastructure and leverage the benefits of a
smart grid technology, which could ultimately save FGC and its customers
millions of dollars."

"We've been working with FGC's Mobile GTES subsidiary to develop and
manufacture two distributed energy storage systems," said Bruce Curtis,
president of grid energy storage solutions for Ener1. "When the units are
installed this fall, we believe they will provide viable solutions to help
strengthen Russia's electric grid in two demanding regions, provide emergency
back-up power for substation auxiliaries, and offer future integration for
intermittent renewable energy sources."

Due to the growth in renewable energy sources like wind and solar and the need
to modernize electric utility grids, the energy storage market is expected to
grow to approximately $2.5 billion globally by 2015*. With expertise
developed over the last few years, Ener1 hopes to work with utility partners
and contractors in countries like the U.S., Japan, Germany, Russia, India and
Brazil to deliver the right energy storage system -- including distributed,
community or bulk energy storage solutions -- to address their power needs.

"We've been collaborating with Ener1 to develop lithium-ion-based energy
storage solutions for Russia's Unified National Power Grid to help improve the
reliability of power delivery to our customers," stated Oleg Bragin, general
director, Mobile GTES. "At the Forum, we plan to demonstrate just how far
we've come in such a short time in developing the distributed energy storage
systems we're installing this fall in St. Petersburg and Sochi."

As part of the St. Petersburg event, the FGC is also sponsoring an
invitation-only roundtable entitled "Smart Grids: Projects of the Future,"
which is designed to educate and encourage debate around issues critical to
wide-spread smart grid deployment around the world. Ener1 Chairman and CEO
Charles Gassenheimer will be one of the industry experts providing
perspectives on the future direction of lithium-ion-based bulk energy storage
solutions for smarter electric grids. The roster of six speakers includes
from the U.S.:

  *George Arnold , national coordinator for smart grid interoperability,
    National Institute of Standards and Technology (NIST)
  *Terry Boston , president and chief executive officer, PJM Interconnection
