NRG Energy Highlights Green Projects at USCAP`s Clean Technology Showcase

USCAP`s Clean Technology Showcase demonstrates innovative methods of reducing
carbon intensity
WASHINGTON--(Business Wire)--
NRG Energy, Inc. (NYSE: NRG) participated in the United States Climate Action
Partnership (USCAP) Clean Technology Showcase held today in Washington, DC.
Legislative staffers and Members of the US Senate were able to learn about NRG`s
investments in nuclear, solar, biomass, clean coal technology and other green
energy technologies, including smart grid technology.

"Climate change is the defining issue for our generation of American leadership,
and further delay in addressing this challenge will be self-defeating in that it
would require a severity of policy that would be damaging to the American public
in a way that addressing the challenge now would not be," said David Crane,
President and CEO, NRG Energy, Inc. "Sound federal climate change legislation
has many important components but a bedrock principle of such legislation must
be that it will promote private sector investment in vital low and no carbon
technologies that will create new jobs and provide a foundation for economic
recovery. Legislation must also protect consumers, vulnerable communities and
businesses while ensuring economic sustainability and environmental
effectiveness."

NRG`s no and low carbon initiatives include:

ABWR nuclear technology-NRG, along with Toshiba Corporation, formed Nuclear
Innovation North America (NINA) to bring proven Advanced Boiling Water Reactor
(ABWR) technology to North America. NINA is currently permitting two additional
nuclear units at the South Texas Project in Bay City, Texas. Expected to be
online in 2016 and 2017, these new units will produce 2,700 megawatts of
carbon-free baseload power-enough to support more than two million homes-while
offsetting more than 21 million tons of greenhouse gases annually. For more
information, please visit www.nuclearinnovation.com.

Solar-NRG is developing solar thermal power plants in California and New Mexico
using eSolar technology. This technology uses a field of small, flat mirrors and
a revolutionary calibration system to track the sun during the day and then
concentrate that sunlight onto a thermal receiver mounted on 195-foot-high
"power towers." The captured sunlight heats water to produce high-pressure steam
that powers a turbine electric generator. Using solar thermal technology, NRG
will produce zero-emission, zero-fuel cost electricity that is coincident with
peak demand on the hottest summer days.

Carbon capture and sequestration-NRG`s post-combustion carbon capture and
sequestration (CCS) demonstration project at WA Parish near Houston, Texas, will
be among the first of its kind and is expected to begin operating in 2013. Using
Fluor`s Econamine FG PlusSM (EFG+) technology, the project will process flue gas
from the plant, capturing approximately 90 percent (or just under half a million
tons) of carbon dioxide (CO2) in the flue gas annually. Captured CO2 will be
either used for enhanced oil recovery or sequestered deep underground at
geological storage sites.

Biomass-NRG recently launched a 20-acre test farm at the Company`s Big Cajun II
plant in New Roads, Louisiana to evaluate the ability of the local environment
to grow dedicated energy crops that can offset a portion of the fossil fuels
consumed by the plant. Since the carbon emitted from the grasses was previously
absorbed from the atmosphere during the growing season, when the biomass is used
as a fuel, it is carbon neutral. NRG is also pursuing biomass co-firing at
existing facilities in Connecticut, Massachusetts and New York. For more
information, please visit www.nrg-econrg.com/biomass.html

Wind-NRG currently owns directly or through a joint venture two west Texas wind
farms and is currently constructing a third which is expected to be online by
the end of the year. This third wind farm will help Texas meet its energy needs
by bringing additional zero-emission, zero-fuel cost electricity to the State.

Smart grid/Electric vehicle-NRG, through its Reliant subsidiary, is developing
Smart Grid offerings such as a new time-of-use rate structure that provides
customers with an incentive to shift their usage to nights and weekends when
electricity is less expensive, and an in-home display that provides real-time
visibility into how much electricity is being used and how much it is costing.
Smart Grid deployments will eventually enable the integration of more
intermittent generation sources such as wind and solar and establish the
infrastructure necessary to support an electric vehicle ecosystem.
