COLUMBUS, Neb. (AP) — Nebraska’s largest utility will keep electricity rates flat overall for next year.

The Nebraska Public Power District’s board approved the 2019 rates on Thursday.

Utility President Pat Pope says NPPD can keep rates stable because employees have been working to reduce costs.

Next year will be the sixth year in a row of stable rates for NPPD’s retail customers. The utility says 2019 will be the second year of stable rates for its wholesale customers.
