North Carolina (NC) data center power coverage
Real, sourced large-load tariff and interconnection research on file for North Carolina — never inferred, never scraped, never implied beyond what's actually been checked.
Large-load tariffs
Tennessee Valley Authority (data center rate / Capacity Commitment Charge)
ThresholdNew or expanding loads above 5 MW
StatusNew standard data center rate effective Oct 1, 2026, approved at the Aug 20, 2026 TVA Board meeting. A Capacity Commitment Charge (CCC) applies to new or expanding loads above 5 MW as part of each data center B, C, and D rate schedule, to recover incremental capacity costs. All-in average billing impact to data center customers is expected to be about 10%, phased in over three consecutive fiscal years. A Power Interruption Provision sets terms for a data center that wants to come online before its generation capacity is available. In-flight data centers must meet specific criteria to qualify for transitional provisions (criteria not detailed in this deck). Separately, the Board updated its policy for new power requirements above 100 MW. The CCC's exact dollar amount or formula was not found in this deck.

Interconnection & regulatory guidance
North Carolina — statewide repeal of the data-center electricity tax exemption (SB 257)
Contact guidanceNo dedicated North Carolina utility large-load tariff is on file here yet (Duke Energy serves most of the state; TVA serves a small western sliver -- see the TVA multi-state entry for that specific territory). Contact the serving utility directly for interconnection process.
ThresholdNot an interconnection/MW threshold -- this is a sales-tax-base change applying to any qualifying or eligible internet data center buying electricity in North Carolina.
ProcessGov. Stein signed SB 257 (the Current Operations Appropriations Act of 2026) on July 7, 2026, repealing the state sales-and-use tax exemption specifically for electricity purchased by qualifying data centers and eligible internet data centers. HB 56 added a 30-day grace period, so the repeal applies starting the first billing period on or after Aug 6, 2026 (varies by the customer's own billing cycle). Electricity is now taxed at the standard 7.0% state sales tax rate regardless of locality. Exemptions for data-center EQUIPMENT and support infrastructure purchases are unaffected -- only the electricity-consumption exemption was repealed.
