Clean Generation

Entergy is a leader in clean generation. More than half of the energy we supply to meet utility demand comes from efficient natural gas-fired generation and clean nuclear generation.

Entergy's investments in fleet transformation and nuclear uprates have greatly reduced both absolute air emissions and emission rates since 2000. Over the past 12 years, our operating companies and Entergy Wholesale Commodities have added approximately 6,000 megawatts of clean, highly efficient combined cycle gas turbines generation and 700 megawatts of non-emitting nuclear generation by increasing capacity at existing plants.
CCGT plants are highly efficient at reducing the amount of fuel burned per kilowatt hour of energy produced, thus greatly reducing emissions. Entergy's strategy has allowed the retirement or reduced use of 5,200 megawatts of older, less efficient legacy gas steam units.
Since 2000, our investments in clean energy capacity have resulted in:

  • 70% reduction in absolute NOx emissions and 75% reduction in NOx emission rates;
  • 32% reduction in absolute CO2 emissions and 43% reduction in CO2 emission rates; and
  • 62% reduction in SO2 emissions and 68% reduction SO2 emission rates.

Entergy's reductions in absolute air emissions were accomplished during a period when our annual electric generation grew by 18 percent.
