JACKSON, Miss. (AP) — Mississippi Power Co. says it will seek to raise rates 25 percent to cover costs of its $2.88 billion Kemper County power plant.
The company has asked the Public Service Commission for a 21 percent increase starting in April, it said Friday. That would cost the typical residential customer more than $20 a month.
The unit of Atlanta-based Southern Co. said it plans to seek an additional increase of 2 percent to 4 percent later, to repay construction costs in excess of $2.4 billion. Mississippi Power wouldn't be allowed to earn a profit on anything it spends above that cap.
The $172 million request comes one day after Mississippi Power announced a settlement in its lawsuit against the PSC. The suit began when the regulatory body rejected an earlier request to start collecting more from customers before the plant starts operation.
"We have worked hard to keep this increase as low as possible," Mississippi Power CEO Ed Day said in the statement. "This is well under the increase we had anticipated and significantly lower than what opponents to the project claimed."
There's still a chance the deal won't stick. The Supreme Court confirmed Friday that it would still hear oral arguments in the case as scheduled Monday. Hattiesburg resident Thomas Blanton, a party to the suit, wants the court to throw out the settlement and reject Mississippi Power's ability to collect money before the plant begins operation.
The settlement will give customers "certainty" about what their rates will be in the future and avoid an even larger jump in bills when the plant goes into service, Southern Co. CEO Thomas Fanning and Chief Financial Officer Art Beatty told analysts on a conference call Friday.
"Overall, the settlement agreement provides a timeline and much-needed transparency on a path forward for Mississippi Power." Fanning said.
The company's credit rating suffered after the earlier denial.
Fanning and Beatty said Mississippi Power expects to include in a traditional rate structure $2.4 billion of the plant's cost, plus the costs of the adjoining lignite mine and pipelines. Mississippi Power will earn a rate of return — a measure of profit — on the amount included in rates.
The cost for the mine is currently estimated at $245 million, while the pipelines are estimated to cost $132 million. That's a total of $2.78 billion, of which Mississippi Power owns 85 percent. The other 15 percent was sold to the South Mississippi Electric Power Association for $500 million.
