Wholesale electric revenues from power sales were as follows:

20242023 (in millions)Capacity and other$652 $630 Energy1,779 1,837Total$2,431 $2,467 

In 2024, wholesale electric revenues decreased $36 million, or 1.5%, as compared to 2023 due to a decrease of $58 million in energy revenues, partially offset by an increase of $22 million in capacity and other revenues. Energy revenues decreased $45 million at the traditional electric operating companies and $13 million at Southern Power primarily due to fuel and purchased power price decreases compared to 2023. Partially offsetting the Southern Power decrease was an increase in the volume of KWHs sold primarily under natural gas and solar PPAs. The increase in capacity revenues was primarily due to a net increase in revenues from capacity contracts at Georgia Power and an increase in capacity revenues associated with natural gas PPAs at Southern Power. The changes in capacity and energy revenues also reflect decreases resulting from power sales agreements that ended in 2023 at Alabama Power and Mississippi Power.

Wholesale electric revenues consist of revenues from PPAs and short-term opportunity sales. Wholesale electric revenues from PPAs (other than solar and wind PPAs) have both capacity and energy components. Capacity revenues generally represent the greatest contribution to net income and are designed to provide recovery of fixed costs plus a return on investment. Energy revenues will vary depending on fuel prices, the market prices of wholesale energy compared to the Southern Company system's generation, demand for energy within the Southern Company system's electric service territory, and the availability of the

Southern Company system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income. Energy sales from solar and wind PPAs do not have a capacity charge and customers either purchase the energy output of a dedicated renewable facility through an energy charge or through a fixed price related to the energy. As a result, the ability to recover fixed and variable operations and maintenance expenses is dependent upon the level of energy generated from these facilities, which can be impacted by weather conditions, equipment performance, transmission constraints, and other factors. Wholesale electric revenues at Mississippi Power include FERC-regulated MRA sales under cost-based tariffs as well as market-based
