FuelCell Energy Awarded 5.6 Megawatts of Ultra-Clean and Efficient Fuel Cell Power Plants by United Illuminating for Renewable Distributed Generation Development

Contracts Executed for a 2.8 megawatt Power Plant in Bridgeport Connecticut -- Second Connecticut Site to be named in the next 30 days

FuelCell Energy, Inc. (Nasdaq:FCEL), a global leader in the design,

manufacture, operation and service of ultra-clean, efficient and reliable
fuel cell power plants, announced another utility-scale award for two 2.8
megawatt DFC3000(r) fuel cell power plants by United Illuminating (UI), part
of UIL Holdings Corporation (NYSE:UIL). One power plant will be located in
Bridgeport, Connecticut as part of a distributed renewable power generation
project that also includes a solar array. The second installation will be
located within the UI service territory at a site to be named in the next 30
days. These two fuel cell plants will provide continuous baseload power to
the electric grid adequate to power approximately 5,600 homes, generated in
a highly efficient and environmentally friendly manner. FuelCell Energy will
install the power plants and operate and maintain them for 20 years under
long term service agreements. The plants are expected to be operational in
early 2015.

"Sustainability at UIL means that we are committed to business practices
that are environmentally and economically responsible," said James P.
Torgerson, President & Chief Executive Officer, UIL Holdings Corporation.
"Purchasing these fuel cell power plants supports our goal of investing in
renewable distributed generation to enhance the reliability of our power
delivery system and offer our customers cleaner energy. We are helping to
implement the State of Connecticut mandate for increased energy production
from renewable sources and help promote energy independence."

"This new fuel cell project plays a significant role in making Bridgeport
one of the greenest cities in America," said Bridgeport Mayor Bill Finch.
"As part of our green efforts, we're creating a new renewable energy park at
the site of an unused landfill by combining this new fuel cell with a solar
field. This renewable energy park will create jobs, generate millions of
dollars in tax revenue, and provide residents with clean and affordable
electricity. In Bridgeport, FuelCell Energy is helping us take the sins of
our past and turning them into shining examples of our city's green energy
future."

The Bridgeport installation will be part of a renewable energy park at
Seaside landfill, with the power plant efficiently converting natural gas
into continuous electricity that is virtually absent of pollutants.
The site will also host an array of solar panels. The total project will
occupy approximately 9 acres of land with the fuel cell power plant using
about one quarter of an acre to produce 2.8 megawatts and approximately
1,000 solar panels occupying about 8 1/2 acres to generate approximately 5
megawatts.

"Megawatt-class fuel cell power plants are helping to transform the power
generation industry with clean, on-site power that enhances the resiliency
and security of the electric grid," said Chip Bottone, President and Chief
Executive Officer, FuelCell Energy, Inc.
"Leadership by the State and Public Utilities Regulatory Authority
(PURA) that acknowledged the need to enable utility ownership of renewable
power combined with the vision of UI culminated in these two transformative
projects to benefit power users and the communities at large."

FuelCell Energy was the successful fuel cell bidder in a competitive
solicitation issued by UI in 2013 under its "Renewable Connections"
program. The program was enabled by the Connecticut legislature under Public
Act 11-80 in 2011, which granted each Connecticut electric utility
authorization to directly own up to 10 megawatts of Class 1 renewable power
generation, including stationary fuel cell power plants. The program was
subsequently approved by PURA and a bill expanding the program by an
additional 50 MW is currently under consideration in the State legislature.

Multi-megawatt fuel cell installations address power generation challenges
for utilities as the combination of near-zero pollutants, modest land-use
needs, and the quiet operating nature of fuel cell power plants facilitates
their siting in urban locations. Fuel cell parks offer a multitude of
advantages for utilities and neighboring communities, including:

-- Environmentally friendly power generation with virtually zero nitrogen
oxide (NOx) that causes smog, sulfur dioxide (SOx) that contributes to
acid rain, or particulate matter (PM10) that aggravates asthma, and the
power is delivered with a low carbon footprint
-- Distributed power generation places power near where it is used,
enhancing the resiliency of the grid
-- Highly efficient power generation process that is economical
-- Continuous renewable power around the clock that is not reliant on
weather or time of day

DFC(r) power plants utilize carbonate fuel cell technology, which is well
suited for megawatt-class applications due to its scalability and favorable
cost profile. Another advantage is that carbonate cells operate efficiently
without the need for noble metal catalysts, such as platinum, which are
required by some other types of fuel cell technology.

The fuel cells bought from FuelCell Energy will serve UI customers by
enhancing the resiliency of the electric grid and delivered in an
environmentally friendly manner.
