Mississippi Power pushes back Kemper IGCC in-service date by a month

Kemper PEPWR

Mississippi Power said Nov. 4 that it continues making progress on the completion of the Kemper County integrated gasification combined cycle power plant.

Last month, the project reached a milestone to date when it generated electricity using syngas from Mississippi lignite coal. As the company continues start-up and commissioning activities at Kemper, Mississippi Power announced it is revising the facility's scheduled in-service date to Dec. 31, 2016.

This one-month extension is needed because on Nov. 2, Mississippi Power determined a maintenance outage on gasifier A, one of the facility's two gasifiers, was needed to make improvements to the ash removal systems. This maintenance to gasifier A follows six weeks of successful syngas production including generation of the plant's first electricity with syngas. During the outage for gasifier A, the company plans to bring gasifier B online to implement the necessary testing ahead of the production of electricity with syngas.

The remaining schedule reflects the time expected to achieve production of electricity using gasifier B, complete outage activities on gasifier A and resume electricity production on gasifier A, as well as to complete the integration of all systems necessary for both combustion turbines to simultaneously generate electricity with syngas.

The company also revised its cost estimate subject to the cost cap for the Kemper project – since the last monthly report to the Mississippi Public Service Commission – to include an additional $25 million related to the schedule extension. All of those costs will be paid by parent Southern Co. and Mississippi Power – not by Mississippi Power customers.

Mississippi Power produces energy for more than 186,000 customers in 23 southeast Mississippi counties.
