Next phase of Superpower Mississippi builds highly efficient, more cost-effective power generation source in Vicksburg

VICKSBURG, Miss. - Vicksburg will once again be home to an Entergy Mississippi power generation source with construction of the Vicksburg Advanced Power Station, the company's latest investment to replace retired, 50-year-old natural gas generation facilities with newer, highly efficient resources. The 754-megawatt combined-cycle combustion turbine facility will be located on the grounds of the former Baxter Wilson Steam Electric Station and, along with already-announced plants in Greenville and Ridgeland, will help ensure Entergy Mississippi's 459,000 customers continue to have efficient, reliable and affordable energy.

Replacing legacy power plants with new, highly efficient power generation sources provides long-term savings to customers. Modern natural gas plants are 40% more fuel efficient than older facilities, saving customers more money on future bills for decades to come.

In the short term, the construction of this and other new generation units at the time of new large industrial technology customers' investments in the grid - like Amazon - will reduce forecasted bill increases by 16% over the next five years.

• Savings include an estimated $1.3 billion in the materials and equipment costs to build new power plants today, compared to the cost to build those facilities on their original schedules. Given the inflationary trends in materials and construction costs, building facilities now will save customers money.
• Our diverse generation portfolio offers us flexibility to lessen the impact on customers' bills should one fuel source spike in price. Additionally, we expect to pass on to customers an estimated savings of $700 million in fuel costs over the life of the new units.

These measures are part of Superpower Mississippi, the largest grid upgrade in the company's history, which makes distribution improvements, adds new generation and prioritizes keeping customers' rates affordable while building an all-of-the-above generation mix that makes the electric grid more reliable and efficient.

While electricity costs are rising nationally, growth in our service area - including new large industrial customers like Amazon - means some of the increased costs for equipment and fuel that otherwise would be incorporated into future bills won't be passed on to our other existing customers. Customers will also share a smaller portion of the costs than they would have to build the same plants on their original schedules.

"Vicksburg is one of the four original cities we began serving in 1923, and we're proud to continue our legacy here with the Vicksburg Advanced Power Station. We're building new natural gas plants in our service area for the first time in more than 50 years. Replacing older plants has been in our long-term resource plan for several years, but we're taking advantage of the economic growth happening in our region to bring modern generation technology online sooner, while minimizing the rate impact to customers' bills," said Haley Fisackerly, president and CEO, Entergy Mississippi.

"These upgrades are not only important to keeping bills affordable for customers, but also to making sure we have the capacity to promote economic development, recruit new and higher paying jobs, and power residential, commercial, industrial and technology growth for Mississippi's future."

"Our reliability effort announced last month combined with this additional commitment to develop new power generation sources means our Superpower Mississippi plan is bringing more power and better power to customers, all at a lower cost to them," Fisackerly continued. "Our state leaders have been instrumental in recruiting large industrial customers, like Amazon, that afford us the ability to provide these significant benefits to customers. And, thanks to support for that growth from Governor Reeves, the Mississippi State Legislature and the Mississippi Public Service Commission, all customers will benefit from lower bills than they otherwise would have seen in the future. We're also grateful to local leaders, like those in Warren County, who welcome these investments that not only help their communities prosper but also serve Mississippi families and businesses throughout the western half of the state."

A $1.2 billion investment, the Vicksburg Advanced Power Station represents a significant economic impact for the area, including more than 560 construction jobs over the next several years and additional tax revenue for Warren County. Entergy will employ about 21 personnel to operate the plant once completed.

This advanced facility will be equipped with combined-cycle combustion turbine technology that primarily uses natural gas and is also designed to support blended hydrogen in the future, mirroring the other power plants Entergy Mississippi is building - Delta Blues Advanced Power Station in Greenville and Traceview Advanced Power Station in Ridgeland. Much like the legacy units that have been cornerstones of our local communities for half a century, these new plants will power life for the next generation of Mississippians and beyond.
