Power Reliability and Rates

Mississippi Power provides electric service to customers in a 23-county area in southeast Mississippi. Our Company is committed to providing our customers with high reliability and exceptional customer service. We strive to maintain superior levels of distribution and transmission reliability throughout our system.

At Mississippi Power, we believe the key to meeting growing energy demands is having a diverse portfolio of energy sources. Diversifying our resources - coal, natural gas, solar energy - allows us to deploy innovative ways to generate clean, reliable and cost-effective electricity, while avoiding an overreliance on one fuel source and staying environmentally responsible. We consider a range of energy sources to balance energy supply with our growing customer demand.

Mississippi Power is a subsidiary of Southern Company, which is one of the largest producers of energy in the country. As part of Southern Company, our energy portfolio includes 11 electric and natural gas utilities capable of producing 44,000 MW of generating capacity as well as 190 Bcf of natural gas storage capacity.

By carefully forecasting energy needs and securing the most economical sources available, we are able to operate our power plants at a 99 percent level of reliability — among the highest in the nation.



Mississippi Power maintains a superior level of transmission and distribution reliability, driven by on-going investment and a strong focus on continuous improvement. That's why our team of skilled employees work everyday to ensure the safe delivery of electricity to homes and businesses across southeast Mississippi.

We have made significant investments to build and maintain a more reliable and smarter system to make, transmit and deliver electricity to our customers. Smart grid technologies, or 'self-healing,' can automatically isolate problems and restore service to affected areas. This system benefits both Mississippi Power and our customers. For our customers, they experience improved reliability and efficiency. For the company, we lower operating costs and we are better able to manage demand.

We are honored to have received the 2015 ReliabilityOneTM Award for Outstanding Midsize Utility.

Sales Tax Exemption on Energy Used in Manufacturing
