NPPD Rates To Stay Unchanged Posted by Deja Andersen Date: December 15, 2019 5:15 pm Leave a comment 8 Views COLUMBUS, Neb. (AP) – Nebraska’s largest utility will keep electric rates flat next year and give customers a small credit on their bills starting in February. The Nebraska Public Power District board approved the 2020 rates on Thursday. Next year will be the seventh year in a row of stable rates for NPPD’s retail customers, who will also receive a monthly credit of between 2% and 4% of their bills. NPPD’s wholesale customers, which include cities and some rural public power districts, will receive slightly larger credits of about 6.2% a month on average in their bills.
