Entergy Mississippi Powering Up Madison County Mega Site

Company to invest $57 million in project to attract economic development, improve reliability


JACKSON, Mississippi –The Mississippi Public Service Commission has approved Entergy Mississippi’s construction of a $57-million substation at the
Madison County Mega Site. The project, which also involves transmission upgrades, will give the industrial site a competitive edge in attracting
large economic development projects. It will also increase service reliability in the fast-growing area of northwest Madison County.

The Madison County Mega Site is in a prime location off Interstate 55 close to the Nissan automotive plant in Canton.

The project is expected to initially serve up to 80 megawatts of electric power and has 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 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.” The Madison County Economic Development Authority is marketing the site to
automotive suppliers, advanced manufacturers and knowledge-based industries.


“Entergy Mississippi’s commitment to Madison County will positively affect the lives of our citizens and the region for generations to come,” said
Joey Deason, executive director of the Madison County Economic Development Authority. “Having a substation that can serve some very large loads
will position our community and region to compete for larger projects that were once considered out of reach due to the availability of electrical
