How Our Electric Rates Are Set

Mississippi Power's rates are set annually by the Public Service Commission using a performance-based review procedure called PEP-4.

The Performance Evaluation Plan ties the price Mississippi Power charges retail customers to how well the company maintains low rates for customers and to performance, based on three factors that have the most impact and reliability.

EP-4 provides for annual evaluations of Mississippi Power's performance-based return on investment. Any rate change is limited to 4 percent of retail revenues per evaluation period before a public hearing is required. PEP-4 will remain in effect until the PSC modifies or terminates the plan.
