The 582 megawatt generating facility is scheduled to start operations in the second quarter of 2015.
The unit was synchronised to the grid last year using natural gas as a fuel.
Over the past 11 months critical testing was done on various components and that testing culminated with the combined cycle unit passing all applicable performance and environmental tests.
During the course of testing the Kemper combined cycle unit logged more than 1200 hours of online generating power for homes and businesses.
To date the unit has generated enough energy to supply 23,000 homes a year.
Another significant milestone – the first gasifier heat up – is scheduled for later this year.
Kemper’s gasifiers are the core of the integrated gasification progress that will be used to convert lignite into synthesis gas.
The use of Mississippi lignite adds fuel diversity at low costs and stable prices for Mississippi Power’s customers.
