Entergy to Invest $57M in New Mississippi Site

The Mississippi Public Service Commission recently approved Entergy Mississippi’s construction of a $57 million substation in Jackson, Mississippi. The site is expected to initially serve up to 80 megawatts (MW) of electric power and will have the capacity to provide up to 300 MW in the future.

Entergy will break ground on the substation in December 2020 with a planned in-service date of December 2021. The company has already qualified the site to reduce the risk and time needed to occupy it.

The project, which will involve transmission upgrades, is intended to increase service reliability in northwest Madison County while also attracting other economic-development projects to the area.

“The Madison County Mega Site has more than 1,000 acres, so we’re targeting larger projects with significant power requirements and high levels of reliability,” said Ed Gardner, Entergy Mississippi director of business and economic development. “The substation has been designed and configured to provide highly reliable transmission service that will ultimately have three independent sources. That means triple redundancy — critical to providing these large manufacturers with extremely reliable power.”

Entergy currently delivers electricity to 2.9 million utility customers in Arkansas, Louisiana, Mississippi and Texas, with an annual revenue of $11 billion.
