LCG, August 27, 2026--Entergy announced today that new revenues from Mississippi data centers are a primary reason why Entergy Mississippi customers will not see their electricity rates increase this summer. The Mississippi Public Service Commission (MSPC) recently approved a rate plan that keeps Entergy Mississippi’s rates below the national average and prevented what otherwise would have been a $4.87 per month increase in July, compared to June rates. Entergy stated that the elimination of the rate increase is an early example of how data centers are directly benefiting their customers.

Entergy Mississippi Highlights New Benefits from Data Centers Are Reducing Customer Bills
LCG, August 27, 2026--Entergy announced today that new revenues from Mississippi data centers are a primary reason why Entergy Mississippi customers will not see their electricity rates increase this summer. The Mississippi Public Service Commission (MSPC) recently approved a rate plan that keeps Entergy Mississippi’s rates below the national average and prevented what otherwise would have been a $4.87 per month increase in July, compared to June rates. Entergy stated that the elimination of the rate increase is an early example of how data centers are directly benefiting their customers.
Entergy further expects over $2 billion in projected savings for Mississippi customers over the next two decades due to Entergy’s "Fair Share Plus Pledge" announced in March. Entergy projects that, as data center customers ramp up their operations, Entergy Mississippi will increase benefits back to customers. For example, Entergy Mississippi recently filed for an additional $0.41 rate reduction that, if approved, would become effective in October. This decrease is related to the ad valorem tax adjustment and is due in part to data center revenue. Flattening rate increases helps offset increases in other areas, especially fuel that is tied to the price of natural gas.
The president and CEO of Entergy Mississippi stated, "At a time when our company is having to replace half-century old power plants to keep up with the energy needs of our almost half-million customers, these data center revenues are providing enormous benefits by covering much of those costs that our other customers would otherwise have had to bear alone. And while we also work to strengthen our power grid against more extreme Mississippi weather for the long term, data center revenues are making those investments more cost-friendly for our customers, too."
In Entergy's announcement, Entergy Mississippi also highlighted its plan to deliver the "Superpower Mississippi" cost-saving actions designed to provide customers more and better power at a lower cost. The first strategy in achieving these goals is to cut outages in half by 2030. With the addition of new, large customers, the company will invest 50 percent more in reliability to help cut outages in half by 2030 at no additional costs to customers. Approximately $18 million of the incremental $300 million for reliability projects announced last year was included and approved in the formula rate plan.
The second strategy is to modernize Entergy Mississippi's generation fleet. The company is building three combined cycle combustion turbine natural gas plants – in Greenville, Vicksburg and Ridgeland – with a combined capacity of over 2,100 MW. Entergy Mississippi expects that accelerating the replacement of retired plants will save an estimated $1.3 billion in materials and equipment costs to build new power plants now, compared with building them on their original schedules. Additionally, the company estimates that modern natural gas plants are 40 percent more fuel efficient than its older plants, so accelerating replacement will deliver cleaner and more cost-effective power generation to Mississippi.
The third strategy is to reduce projected bill impacts through the company's diverse generation portfolio, which provides flexibility to lessen the impact on customers’ bills if one fuel source spikes in price. With more advanced power generation assets, Entergy Mississippi expects to pass on to customers an estimated savings of $700 million in future fuel costs. Customers would have shouldered the costs to make these upgrades, but instead, expected bill increases will be lower than they otherwise would have been because Amazon and other large industrial customers are paying 100 percent of their own costs to be on the grid, plus bringing these added benefits for all customers.
Entergy Mississippi's president and CEO said, "It is important to remember this has been a team effort. These benefits our customers will see on their power bills would not have been possible without Governor Reeves’ help in recruiting one of the world’s leading technology companies to our state, the Mississippi Legislature’s review and approval of it, and the guidance and oversight of the Mississippi Public Service Commission."
