Otter Tail Power Co Electricity Rate per kWh (2024 EIA Data)

Otter Tail Power Co is an investor-owned electric utility that reports to the U.S. Energy Information Administration under utility number 14232. In 2024 it served 50,118 bundled residential customers in Minnesota (its largest state of 3), and its average realised residential price was 11.33 cents per kWh: $57 million of residential revenue divided by 506,692 MWh of residential sales.

Across the other sectors, Otter Tail Power Co's 2024 average prices were 9.31 cents for commercial customers (13,197 accounts) and 5.40 cents for industrial customers (11 accounts). Industrial customers paid 5.93 cents less per kWh than households, a 52% discount that is typical of high-volume, high-voltage service.

Within Minnesota, Otter Tail Power Co ranked number 8 of 47 utilities with bundled or delivery service by residential accounts served (50,118) and accounted for 2.30% of the state's residential electricity sales in 2024, measured in MWh sold or delivered rather than in customers. The state-wide average realised residential price in 2024, computed from the same EIA file, was 15.45 cents per kWh, so Otter Tail Power Co's customers paid 4.12 cents below the Minnesota average (-26.7%). For context, EIA's latest monthly figure for Minnesota is 17.52 cents per kWh (June 2026, Electric Power Monthly); that is a different, more recent measure across all utilities and is not directly comparable with a 2024 annual average.
