How NINE MILE POINT compares
With 1,960 MW of capacity, NINE MILE POINT is the largest of the 72 operating power plants Bywatts maps in Louisiana and the largest of the 41 operating Natural Gas plants in the state. It accounts for about 13% of Louisiana's operating Natural Gas capacity and 7.9% of all operating capacity in the state. Nationally it is the 16th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1971, it is older than 66% of the 72 operating Louisiana plants with a recorded commissioning year. Its operator, ENTERGY LOUISIANA INC, runs 7 operating plants in Louisiana totaling 7,130 MW. It shares Jefferson Parish with one other operating plant, EXXONMOBIL GRAND ISLE GAS.
EIA-860 lists 5 generators at the site with 2,440 MW of nameplate capacity, mainly natural gas steam turbine technology (this page's HIFLD capacity figure is 1,960 MW). Net generation was 8,928 GWh in 2024 (a 42% capacity factor), up 6% from 2022. Its generators came online between 1971 and 2014.
