Schedule of Long-term Contracts for Purchase of Electric Power

The number of LPCs by contract arrangement, the revenues derived from such arrangements for the three and nine months ended June 30, 2022, and the percentage those revenues comprised of TVA's total operating revenues for the same periods, are summarized in the tables below:

TVA Local Power Company Contracts At or for the Three Months Ended June 30, 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						146						$	2,250					75.8		%
5-year termination notice						7						412						13.9		%
Total						153						$	2,662					89.7		%

Note

(1) Ordinarily, the LPCs and TVA have the same termination notice period; however, in a contract with one of the LPCs with 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.

TVA Local Power Company Contracts At or for the Nine Months Ended June 30, 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						146						$	6,473					76.7		%
