Long-term Contract for Purchase of Electric Power [Line Items] |
Long-term Contracts or Programs Disclosure [Text Block] | The number of LPCs by contract arrangement, the revenues derived from such arrangements for the three months ended December 31, 2022, and the percentage those revenues comprised of TVA's total operating revenues for the same periods, are summarized in the table below:
TVA Local Power Company Contracts At or for the Three Months Ended December 31, 2022
Contract Arrangements(1) |  | Number of LPCs |  | Revenue from Sales of Electricity to LPCs (in millions) |  | Percentage of Total Operating Revenues
20-year termination notice |  | 147 |  |  | $ | 2,345 |  |  | 77.8 | %
5-year termination notice |  | 6 |  |  | 361 |  |  | 12.0 | %
Total |  | 153 |  |  | $ | 2,706 |  |  | 89.8 | %
Note (1) Ordinarily, the LPCs and TVA have the same termination notice period; however, in a contract with one of the LPCs with a five-year termination notice, TVA has a 10-year termination notice (which becomes a five-year termination notice if TVA loses its discretionary wholesale rate-setting authority). Certain LPCs have five-year termination notices or a shorter period if any act of Congress, court decision, or regulatory change requires or permits that election.
