TVA Reports $4.9 Billion Operating Revenue For First 2 Quarters Fiscal Year 2021 Tuesday, May 4, 2021 The Tennessee Valley Authority reported $4.9 billion in total operating revenues on 76.4 billion kilowatt-hours of electricity sales for the first two quarters of fiscal year 2021 ended March 31. Sales of electricity were 3 percent higher due to an 8 percent increase in heating degree days over the same period in the prior year, and an increase in sales to directly served customers. Total operating revenues decreased 4 percent over the same period of the prior year driven primarily by lower effective base rates and lower fuel cost recovery revenues as a result of lower fuel rates offset by higher demand volume.
