Entergy Mississippi is building its first new gas plant in 50 years

For the first time in 50 years, Entergy Mississippi is building a new natural gas-fired plant, which will be the first combined-cycle combustion turbine power station the company has built from the ground up.

While natural gas is the primary resource, Entergy said the facility will be designed to support blended hydrogen to produce energy as well.

The company said it will “eventually” retire the Gerald Andrus Steam Electric Station, which is currently located in Greenville. Entergy Mississippi claims it is producing more electricity from the same amount of fuel while reducing carbon emissions by replacing older power plants with “more advanced and efficient” technology.

Over the past two decades, the utility has bought three natural gas power stations – Attala Plant in Sallis (2006), Hinds Energy Facility in Jackson (2012) and Choctaw Energy Facility in French Camp (2019).

In addition to the current natural gas units, the Sunflower Solar Station near Ruleville (built in 2022) and the Grand Gulf Nuclear Station in Port Gibson (built in 1985) are generating electricity and contributing to the company’s power generation mix. Entergy Mississippi purchased the solar facility and owns a portion of the nuclear plant.

The new power station is expected to be completed in 2028.
