Tennessee Valley Authority

TVA's service area, the area in which it sells power, is defined by the Tennessee Valley Authority Act of 1933, as amended ("TVA Act"). TVA supplies power in most of Tennessee, northern Alabama, northeastern Mississippi, and southwestern Kentucky, and in portions of northern Georgia, western North Carolina, and southwestern Virginia. Under the TVA Act, subject to certain minor exceptions, TVA may not, without the enactment of authorizing federal legislation, enter into contracts that would have the effect of making it, or the wholesale customers that distribute TVA power ("local power company customers" or "LPCs"), a source of power supply outside the area for which TVA or its LPCs were the primary source of power supply on July 1, 1957. This provision is referred to as the "fence" because it bounds TVA's sales activities, essentially limiting TVA to power sales within a defined service area.

Note

(1) TVA locations shown here were in service as of September 30, 2025.

(2) In addition to the locations above, TVA owns approximately one megawatt ("MW") of nameplate capacity among nine operating solar installations across the Tennessee Valley region with six installations in Tennessee, two in Alabama, and one in Mississippi. See Power Supply and Load Management Resources for a description of all of TVA's power supply resources.

In addition, the Federal Power Act ("FPA") includes a provision that helps protect TVA's ability to sell power within its service area. This provision, called the "anti-cherrypicking" provision, prevents the Federal Energy Regulatory Commission ("FERC") from ordering TVA to provide access to its transmission lines to others to deliver power to customers within TVA's defined service area. As a result, the anti-cherrypicking provision reduces TVA's exposure to loss of its customers. However, there have been some efforts to circumvent the anti-cherrypicking provision, and the protection of the provision could be limited and perhaps eliminated by federal legislation at some time in the future. See Competitionand Item 1A, Risk Factors— Regulatory, Legislative, and Legal Risks — TVA could lose its protected service territory.

In 2025, the revenues generated from TVA's electricity sales were $13.5 billion and accounted for virtually all of TVA's revenues. See Note 18 —Revenue for details regarding revenues by state for each of the last three years.
