Gulfport, Miss. – Mississippi Power announced today it had achieved another major milestone with electricity generated in the second gasifier at the Kemper County energy facility by synthesis gas, or syngas, from lignite. Last month, the company announced electricity had been generated in the first of the facility’s two gasifiers.

“This is a substantial step forward for the project,” said Mississippi Power Chairman, President and CEO Anthony L. Wilson. “We are now closer to integrating all of the systems at the facility to deliver on our mission to provide clean, reliable energy for our customers. I cannot be happier with this step in the process.”

The company announced earlier this month it was completing maintenance on the first gasifier at the plant, which followed six weeks of successful syngas production including generation of the plant’s first electricity using syngas.

The remaining major milestones for the IGCC include successful carbon capture and integration of all systems necessary for both combustion turbines to simultaneously generate electricity with syngas. The expected date for the plant to be placed in service is Dec. 31.
