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. In 2017, the most recent
benchmarking data available, Entergy’s emission rate was 601 pounds per MWh,
much lower than the national average of 1,041 pounds per MWh.
As a result of our portfolio transformation strategy, natural gas
represents 38 percent of our existing utility generation sources. Our
new-build natural gas-fired units, in operation, proposed or under
construction, represent nearly 4,000 MW of new generation. Replacing older
generation with new natural gas-fired units offers several advantages. These
units will improve system reliability, increase environmental efficiency and
reduce costs for our customers by using less fuel and improving fleet
efficiency.
New units also have lower maintenance costs, produce up to 40
percent fewer carbon emissions and require less water. Since 2000, while our
annual electric generation grew by 18 percent, our investments in clean
energy capacity have resulted in:
- 70 percent reduction in absolute NOx emissions and 75 percent
reduction in NOx emission rates;
- 32 percent reduction in absolute CO2 emissions and 43 percent
reduction in CO2 emission rates;
- 62 percent reduction in SO2emissions and 68 percent reduction SO2
emission rates; and
- 91 percent reduction in Hg emissions and 92 percent reduction
Hg emission rates.
Our energy mix includes approximately 2 million MWh of renewable energy,
which consists of hydro, solar, biomass, landfill gas, waste heat recovery
and wind renewable energy credits. This represents nearly 2 percent of our
generation sources used to meet utility demand in 2017. While still a small
portion of our utility generation, technological advances are making
renewable energy as well as certain distributed energy resources
increasingly cost-competitive.
Over the next three years we are pursuing 1000 MW of renewable resources.
Two power purchase agreements in Arkansas represent approximately 180 MW,
and of the remainder, approximately half represent ownership opportunities.
Entergy Louisiana signed a 20-year agreement to buy the output of a
proposed 50-megawatt solar photovoltaic power plant, the largest solar
facility currently planned for Louisiana, once it is up and running in early
2020.
