GULFPORT, Miss. – Mississippi Power today announced it is extending the expected in-service date of the Kemper County energy facility until late February 2017.

The company continues final start-up activities at the project, achieving integrated operation of both gasifiers, including the production of electricity from syngas in both combustion turbines, on Jan. 29, 2017, with sustained operation through the present time. This is the facility’s most significant milestone to-date.

The updated schedule reflects an approximate one-week outage necessary to repair and make modifications to further improve the plant’s ability to achieve sustained operations sufficient to support placing the plant in service for customers.

The company has revised its cost estimate subject to the cost cap for the Kemper project by $51 million. These increased costs will be paid by Southern Company and Mississippi Power – not by Mississippi Power customers. 

Mississippi Power also today announced that as a result of a revised estimate of ongoing operating costs for the project and a decrease in the most recent forecasting of long-term projected natural gas costs, the company is updating its economic viability analysis of the project. This analysis is expected to be complete before the end of February 2017.

Mississippi Power, a subsidiary of Southern Company (NYSE: SO), produces safe, reliable and environmentally responsible energy for more than 186,000 customers in 23 southeast Mississippi counties. Mississippi Power earned the 2015 ReliabilityOneTM Award for outstanding midsize utility for excellence in storm restoration and recovery efforts as well as being a leader in reliability, customer service and safety.
