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 nine million customers in Tennessee, Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.
