Audit the full service average
Revenue 4,760 thousand dollars. Sales 45,165 MWh. Customers 2,335. Cents per kWh = revenue ÷ megawatt-hours × 100. Monthly bill = revenue × 1,000 ÷ customers ÷ 12.
Why the bill spikes
Season
The 2025 monthly average in South Dakota was 984 kWh. A hot or cold month can sit far from that. Compare kilowatt-hours with the same month last year before you blame the rate.

How to lower the bill
- Read kilowatt-hours first. If use is up, the dollar total can rise on an unchanged rate.
- Check whether the read is actual or estimated. The true-up rule needs verification in the tariff.
- If a supplier or aggregator is also on the account, add that charge to the utility charge.
- Ask about budget billing and an income-qualified discount. Eligibility needs verification.
- If you are on time-of-use, move flexible load out of the expensive window. Confirm the window on the tariff.
