JACKSON, Miss. – Entergy Mississippi is meeting customers’ power needs to provide more and better power by making a five-year investment in reliability, while keeping rates far below the national average. And the large industrial investments that companies like Amazon have made in Mississippi will help fund the effort.

Superpower Mississippi is the largest, most comprehensive grid upgrade in the company’s history and will save customers millions in costs that otherwise would be included in future bills. Although Entergy Mississippi makes power reliability investments every year that are already included in customer bills, we will be asking the Mississippi Public Service Commission for approval to increase total spending on grid improvements by 50%, or $300 million, at no cost to Mississippi customers. This spending increase to strengthen the power grid is possible because of new revenues provided by Amazon and other large industrial customers’ investments in Mississippi, and it will help us target a significant goal for the first time – to cut power outages for Entergy Mississippi customers in half within five years. With $600 million in grid improvement investments already included in current and future plans, these new investments will bring the total improvement project to almost $1 billion toward a stronger grid.

The plan aims to reduce the overall frequency and duration of outages for the average Mississippi customer by approximately 50%, excluding major weather events. The reliability work includes:

• Installing stronger poles that are designed to withstand extreme weather conditions
• Implementing more smart devices and real-time monitoring systems, and exploring additional self-healing networks that automatically identify faults, reroute power and restore service faster
• Increasing tree-trimming and dead tree removal measures to help prevent and decrease outages throughout Entergy Mississippi’s service area

“Superpower Mississippi will transform the power grid like we’ve never seen before with better power at a lower cost. With this additional $300 million dollars, we’re investing 50% more in reliability to reach a 50% reduction in outages, all at 0% added cost to our customers,” said Haley Fisackerly, president and CEO, Entergy Mississippi.

Any large, industrial or data center customer helps pay for the upkeep and expansion of the power grid that everyone uses, easing the costs that residential customers bear for their own household power needs.

“We were facing a moment where the growth in our service area was not moving as quickly as our projected costs, which would have resulted in significant rate increases. The solution we needed – and found – was to attract growth to our service area in the form of a large customer that could help share in the costs to serve all our customers and bring down future costs for everyone,” said Fisackerly. “We appreciate Governor Reeves and the Mississippi Legislature’s foresight to pass legislation that is bringing large customers, like Amazon, to the state. We’re also grateful for the Mississippi Public Service Commission continuing to ensure benefits for customers and provide oversight of these investments.”

Vegetation-related outages have increased in recent years due to the millions of dead trees caused by the 2023 drought and intensified severe weather, from thunderstorms to tornadoes. Outages caused by fallen trees, many of which are outside the areas Entergy Mississippi can trim, have nearly doubled in the first eight months of 2025 compared to the three-year average in the same time period before the drought.

“In addition to our normal trimming practices, we’ve already trimmed or removed more than 25,000 dead trees this year to help ease the effects of the drought on the grid. Superpower Mississippi helps us tackle even more vegetation risks while also improving resiliency,” Fisackerly said.

Customers can expect to see reliability work begin immediately across Entergy Mississippi’s 45-county service area and continue over the next five years. In addition to these improvements, customers can look forward to power generation portfolio benefits in the future, as we transform the power grid through Superpower Mississippi and help keep costs lower than they otherwise would be in the future.
