Ratepayers will see lower electric bills this fall as Entergy Mississippi reports reductions in fuel-related costs.

Bills will go down about 11 percent, or from about $99.40 to $88.28 for typical residential use of 1,000 kilowatt hours a month, said Central District Public Service Commissioner Lynn Posey in a statement released Friday.

“The industry is experiencing a period of lower natural gas costs and those savings are passed along to customers,” Posey said. “I am pleased to order this rate reduction and continue to be committed to reasonably priced and highly reliable utility service.”

The reduction is due to rate adjustment requests filed quarterly by Entergy Mississippi based on what the company is paying for natural gas used in the generation of electricity, said spokesman Don Arnold. After those fuel costs soared in 2008, they’ve steadily gone down since, Arnold said.

The adjustment will take effect with bills issued after Oct. 1.

Entergy Mississippi serves about 433,000 customers statewide and about 22,000 in Vicksburg and Warren County.

Generating facilities include the natural-gas fired Baxter Wilson plant in Vicksburg, as well as coal-fired generating plants and Grand Gulf Nuclear Power Station outside Port Gibson.

Entergy New Orleans, serving about 150,000 customers, has also announced rate reductions of about 4 percent, attributed to an increase in its customer base with rebuilding in the city and the return of residents as the city recovers from Hurricane Katrina, which hit in 2005.
