NEW YORK, Sept. 13, 2011 /PRNewswire/ -- Ener1, Inc. (NASDAQ: HEV), a leader
in lithium-ion energy storage solutions, today announced it has completed
several milestones for its contract with Russia's Mobile GTES, a wholly-owned
subsidiary of Federal Grid Company (FGC) of Unified Energy System (MICEX:
FEES), to co-develop lithium-ion-based distributed energy storage systems as
part of a nation-wide grid modernization program.

As part of the $40-million supply and consulting agreement, Ener1 has
developed and manufactured two distributed energy storage systems, which have
been tested and certified by KEMA, one of the leading independent testing and
certification companies for the energy and utility industry. The KEMA
certificate provides assurance that the system has been tested to meet the
standards required under Ener1's agreement with Mobile GTES, as well as
certain reliability and safety requirements.

"Achieving the KEMA certification milestone gives us the confidence that our
systems are designed and manufactured to the standards required for these
particular energy and utility applications," stated Ener1 President Chris
Cowger. "Once installed, we believe these units will be viable solutions in
providing back-up power for two power substations and for future integration
of intermittent renewable energy sources, as part of Russia's electric grid
modernization effort."

Ener1's first system was delivered to the Black Sea port city of Sochi, where
it is currently being installed, tested and commissioned to provide
large-scale emergency power backup for the micro-grid being built to support
the 2014 Winter Olympic Games. The second unit is anticipated to be shipped
to St. Petersburg -- where it will be installed, tested and commissioned --
later this year. Having achieved these milestones with Mobile GTES, Ener1 has
received several additional payments since August 25 totaling more than $13
million. To date, Ener1 has received more than $20 million as part of the
supply contract.

In addition to these commercial scale distributed energy storage systems,
Ener1 also developed a fully operational, 70-kWh demonstration unit, which it
previously shipped to Russia. The Federal Grid Company will display the
operational unit in its exhibit at the upcoming Sochi International Investment
Forum to be held September 15-18. The exhibit will provide attendees with a
better understanding of how these two companies could strategically manage
energy storage for the country's electric grid.
