TVA data center capacity commitment charge (2026)
Tennessee Valley Authority — Capacity Commitment Charge on Data Center Loads Above 5 MW, About $1.5M per Megawatt (Approved August 20, 2026; Effective October 1, 2026)
Tennessee Valley Authority · Tenn. Valley Auth. Bd. of Dirs. — Data Center Capacity Commitment Charge (approved Aug. 20, 2026; eff. Oct. 1, 2026)
- Status
- In effect
- Took effect
- October 1, 2026
- Applies to
- New or expanding data center customers with loads above 5 MW taking power from TVA; local power companies distributing TVA power.
- Enforced by
- Tennessee Valley Authority
The Tennessee Valley Authority's Board of Directors approved a separate, higher wholesale rate for data centers on August 20, 2026, effective October 1. New or expanding data center loads above 5 megawatts now fall under a Capacity Commitment Charge attached to TVA's data center rate schedules, designed to recover the incremental capacity costs those customers impose on the system. The headline figures are substantial: upfront capacity commitment charges of roughly $1.5 million per megawatt, payable over three to five years, and an all-in average billing increase for data center customers of about 10%, phased in across three consecutive fiscal years. The stated purpose is to keep residential rates low while still serving growing data center demand. TVA matters here out of proportion to a single utility. It is a federal corporate agency supplying power across seven states, so this is not a state rate case but a regional cost-allocation decision reaching a large share of the Southeast — and TVA is among the first large US utilities to adopt a tariff aimed specifically at AI-driven load. Where most 2026 measures in this dataset restrict where data centers may be built, this one changes what they pay to run.
Who is protected: Residential and general-service ratepayers across TVA's seven-state service territory, protected from absorbing the incremental capacity costs of data center load through a charge assigned to those customers directly.
Legal detail
Tennessee Valley Authority Board of Directors approval, August 20, 2026, of a new wholesale rate structure for data centers, adopted within the recommendations of TVA's Integrated Resource Plan; effective October 1, 2026. MECHANISM: new or expanding data center loads above 5 MW are subject to a CAPACITY COMMITMENT CHARGE attached to TVA's data center rate schedules, structured to recover the incremental capacity costs attributable to those customers. QUANTUM: upfront capacity commitment charges of approximately $1.5 million per megawatt, payable over three to five years; projected all-in average billing impact on data center customers of approximately 10%, phased across three consecutive fiscal years. STATED OBJECTIVE: hold residential rates down while continuing to serve data center growth. INSTITUTIONAL SIGNIFICANCE: TVA is a federal corporate agency, not a state-regulated utility, and supplies power across seven states, so this is a regional cost-allocation decision rather than a single-state rate case — it reaches a materially larger footprint than any state PUC order in this dataset. TVA is reported as among the first large US utilities to adopt a dedicated tariff targeting AI-driven load. INSTRUMENT CLASS: a demand-side price signal, distinct from the siting restrictions (moratoriums, zoning, bans) that dominate the 2026 municipal record and from the procurement mandates (Delaware HB 445, Nebraska LB 1261) that require large users to bring their own generation. Status recorded as `enacted` because the October 1, 2026 effective date had not arrived at verification.
