KNOXVILLE — Rain is a good thing for Tennessee Valley Authority customers.
The utility’s fuel cost will decrease slightly in the May billing — as much as 50 cents for average residential customers — due partly to increased hydro generation from heavy rainfall.
Effective April 1, TVA changed its 19-year-old rate structure to promote energy efficiency and reduce peak power demand.
The nation’s largest public utility provides power to distributors with some 9 million customers in Tennessee, Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.
