Kemper reaches most significant milestone yet toward coal gasification
Testing supports project's dual-fuel generating capability
Company's monthly PSC report: No schedule change, cost estimate increase of $110 million

GULFPORT, Miss., Oct. 27, 2015 /PRNewswire/ -- Mississippi Power's Kemper County energy facility has reached its most significant milestone to date with the testing of one of the project's coal gasification units.

The test of the first of two coal gasification units, or gasifiers, involves the injection of sand into the equipment under operational conditions. The test is used as a major step before injecting lignite in the gasifiers for final operational testing.

"The testing of the gasifier at Kemper is a huge step toward achieving full operation of the project in the first half of 2016," said Ed Holland, chairman and CEO of Mississippi Power. "This is one of the most important steps toward completion of the project. It demonstrates the first gasifier and related systems are working as designed to support the project's generating capability of producing syngas from lignite."

Syngas, or synthesis gas, will be supplied to Kemper's combined cycle power plant from the gasification of locally-mined Mississippi lignite once the gasifiers are operational. The plant has been operating successfully using natural gas and producing power for customers since August 2014.

"By having demonstrated its reliability over the past 14 months, the combined cycle's dual-fuel design to use both syngas and natural gas should provide fuel flexibility for the benefit of customers," said Holland. "Following the completion of the testing of both gasifiers, our next step will be to inject lignite into the gasifiers and produce syngas, which is expected to occur in the first part of next year." 

Additionally today, Mississippi Power filed its monthly report for September with the Mississippi Public Service Commission. As noted in the company's August monthly report, the company was reviewing the schedule for the project. Based on the completion of the review, the Kemper project's schedule remains unchanged with completion still expected in the first half of 2016.

Also noted in last month's report was the previous cost estimate for the Kemper project that included costs through March 31, 2016. The company has revised its cost estimate subject to the cost cap for the Kemper project to include approximately $110 million in cost increases for September. This increase includes approximately $20 million of adjustments related to start-up and commissioning activities as well as operational readiness activities during the month, and approximately $90 million of additional schedule costs for the months of April-June of 2016.

These costs are in addition to previous adjustments made in the July and August reports, bringing the total adjustments subject to the cost cap for the third quarter to approximately $150 million. Customers will not pay for any of this increase in capped costs.
