Mississippi Power says Kemper will cost more, take longer

Mississippi Power on Tuesday added two months and $110 million toward getting the lignite portion of its Kemper County power plant operational.

In the December report to the state Public Service Commission, Mississippi Power increased its cost estimate by $110 million. The company said $40 million of that is for charges related to startup and commissioning activities in December, including repairs and modifications to the refractory lining inside the gasifiers, and $70 million for the extension of the expected start date from the end of June to the end of August.

The company says it expects the lignite startup by Aug. 31.
