Mississippi Power Plants

Generating energy: Our diverse portfolio benefits you

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.

Mississippi Power employs hundreds of highly-skilled and safety-minded workers at our generating facilities. 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.
