Power Plants

Mississippi Power has a generating fleet made up of both coal and natural gas power plants. This diversity is key to keeping energy costs stable. With hundreds of highly-skilled and safety-minded workers, we currently operate six power plants.

The key to meeting our growing energy demands is having a diverse portfolio of energy sources. Diversifying our resources allows us to deploy innovative ways to generate clean, reliable and cost-effective electricity, while avoiding an overreliance on one fuel source.


Mississippi Power continually considers a range of energy sources to balance energy supply with our growing customer demand, which is updated and presented for approval annually to the Mississippi Public Service Commission.
