Entergy investing big in 4 GW of new gas-fired capacity over coming years

Entergy Corp.’s utilities in Louisiana, Arkansas, Texas and Mississippi are either building, close to completing or acquiring more than 4 GW of gas-fired generation capacity over the coming year.

The New Orleans-based utility announced the projects in its Integrated Report released this week. Entergy also has plans on adding both utility-scale and rooftop solar as it replaces three older generation plants.

The first coming online will be the St. Charles Power Station, Entergy Louisiana’s 980-MW combined-cycle gas turbine (CCGT) unit in Montz. Construction is continuing at St. Charles and projected to go into service by this summer.

Another online project is the Lake Charles Power Station. The 994-MW CCGT facility is expected to be completed by 2020.

Entergy Louisiana also has gained state regulatory approval to acquire the Washington Parish Energy Center, a 361-MW simple-cycle combustion turbine plant in Bogalusa. Washington Parish should be in action by 2021, according to the integrated report.

Energy’s Mississippi unit plans to close later this year on its acquisition of an 810-MW CCGT power plant in French Camp, Miss. Earlier this year, Entergy New Orleans began construction on the 128-MW New Orleans Power Station, which will be gas-fired reciprocating internal combustion engines and gensets expected to be online and offering grid support by 2020.

Entergy Texas began work this year on the Montgomery County Power Station with completion by 2021. The 993-MW Montgomery County project, one of the its first in decades in that region, will be located next to the company’s existing Lewis Creek power units.

In November, Entergy Corp. reached a deal with the Sierra Club and National Parks Conservation Association to retire coal-fired generation at certain facilities, the report reads. The deal allowed Entergy to move ahead with the gas-fired and solar plans to replace retiring capacity.
