Mississippi Power on Friday added a month to the date it expects to have the Kemper energy facility operational on lignite and increased the cost.
The date was revised from Nov. 30 to Dec. 31, and Mississippi Power said it needs an additional $25 million that will be paid by the utility and Southern Company — not customers.
On Wednesday, the company determined that improvements were needed on one of the gasifier’s ash removal system, which it said caused the need for the extension. While gasifier A is undergoing maintenance, the company said gasifier B will be brought online for testing ahead of the production of electricity with syngas.
The extension also gives more time to complete outage activities and resume electricity production on the first gasifier, the company said, and will allow them to complete integration of all systems for both units to simultaneously generate electricity with syngas.
