Item 8.01        Other Events.

On November 26, 2019, Mississippi Power Company (“Mississippi Power”) filed a base rate case (the “2019 Base Rate Case”) with the Mississippi Public Service Commission (the “PSC”). The filing includes a requested annual decrease in Mississippi Power’s retail rates of $5.8 million, or 0.6%, which could be effective as early as 30 days after the filing unless suspended by the Mississippi PSC.   The decrease in rates is driven primarily by changes in the amortization rates of certain regulatory assets and liabilities and cost reductions, partially offset by an increase in depreciation associated with the filing of an updated depreciation study. The revenue requirements included in the filing are based on a projected test year period of January 1, 2020 through December 31, 2020, a 53% average equity ratio, and a 7.728% return on investment. The filing reflects the elimination of separate rates for costs associated with the Kemper County energy facility and energy efficiency initiatives; those costs are proposed to be included in the Performance Evaluation Plan, Environmental Compliance Overview Plan and ad valorem tax adjustment factor, as applicable. Mississippi Power expects the Mississippi PSC could issue a final order in this matter within 120 days of the filing.  

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.
