Louisiana Generating, a wholly owned subsidiary of NRG Energy, Inc. (NYSE:
NRG), will continue emissions reductions at the Big Cajun II Electrical
Generating Station while providing affordable power to cooperative customers
in Louisiana.

After buying Big Cajun II, Louisiana Generating upgraded the burners and fuel
that reduced nitrogen oxide (NOx) and sulfur dioxide (SO[2]) emissions by a
third.These additional changes and upgrades announced today will further that
progress. Work will be done during regularly scheduled outages and completed
by April 2015.

“We are very proud of the work we have done to reduce emissions at Big Cajun
II over the decade we have owned the plant,” said Jennifer Vosburg, President
of Louisiana Generating. “We are equally proud of the work we will do over the
next three years to make Big Cajun II even cleaner.”

To meet EPA’s Mercury Air Toxics Standards (MATS) requirements, Louisiana
Generating will convert one of the three units at the plant from coal to
natural gas, eliminating virtually all mercury and particulate matter from the
unit’s emissions. Louisiana Generating will also install activated carbon
injection on another unit and upgrade the electrostatic precipitators. MATS
goes into effect in April of 2015.

“This conversion will allow us to meet new EPA regulations as we see greater
diversity and flexibility in our ability to meet the power needs of our
customers on the hottest and coldest days,” said Vosburg. “All plants across
the nation will have to meet these new EPA requirements and through this
natural gas conversion, we have selected the route that ensures our co-op
customers will benefit from cleaner and more diverse power as they continue to
enjoy electricity costs that are among the lowest in Louisiana.”

Separate from the new regulation, Louisiana Generating has also settled
decade-old charges by the Environmental Protection Agency and the Louisiana
Department of Environmental Quality for work done by the previous owner of the
Big Cajun II Electric Generating Station.With this agreement, Louisiana
Generating will:

  *Install Selective Non-Catalytic Reduction (SNCR) control equipment to
    reduce nitrogen oxide on all three units.
  *Install Dry Sorbent Injection equipment on Unit 1 to reduce sulfur

The capital cost of making the plant modifications and achieving the emission
improvements are within the total environmental capital costs previously
disclosed publicly by NRG.

“This agreement provides greater strength for Big Cajun II through additional
controls that will allow the plant to comply with environmental regulations
both now and in the future,” said Vosburg. “In addition, the mitigation
projects covered by the agreement will provide an opportunity to give back to
our community as it showcases NRG Energy's alternative energy solutions such
as solar and electrical vehicles in Louisiana. This is a win-win-win situation
– a win for the environment, a win for our customers and a win for our
