In addition to the 2019 Base Rate Case, Mississippi Power made its annual retail fuel filing, which includes a requested decrease in annual retail rates of $23.8 million, or 2.6%, as a result of lower fuel costs. Mississippi Power expects the Mississippi PSC to authorize these rates to go into effect no later than the first billing cycle of February 2020.

The ultimate outcome of these matters cannot be determined at this time.
