Mississippi Power has filed a Fuel Cost and Energy Cost Management Recovery request with the Mississippi Public Service Commission.
The company says it's seeking a total increase of 3.35 percent.
If granted by the PSC, Mississippi Power says the average residential customer would see bills increase by 2.66 percent per month beginning in 2014.
MPC officials said the actual rate impact of the filings to customers will be determined after the commission reviews and renders its decision.
The PSC is expected to hear the company’s fuel filing in December.
Mississippi Power says each year it projects the exact amount of fuel necessary to generate electricity for customers for the upcoming year. It says when the fuel price is lower than expected, the lower cost is passed on to the customers the following year. When the fuel price is higher than expected, the difference is requested to break even.
