The rate on the record
Investor-owned base rates are usually set in a state docket. Riders can change outside a full rate case. Average revenue per kilowatt-hour is total residential revenue divided by residential sales. It is not a tariff schedule.

Audit the full service average
Revenue 534,866.6 thousand dollars. Sales 3,738,727 MWh. Customers 334,336. Cents per kWh = revenue ÷ megawatt-hours × 100. Monthly bill = revenue × 1,000 ÷ customers ÷ 12.
Why the bill spikes
Season
The 2025 monthly average in West Virginia was 1,073 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.

Using 2025 EIA-861 revenue and sales, the full service average was 14.31¢ per kWh. Average use was 932 kWh a month and the average bill was $133.32. This folds in whatever customer charges and riders the utility reported. It is not the marginal rate on your tariff.
Did Mon Power raise rates?
The full service average price changed +2.4% from 2024 to 2025, from 13.97¢ to 14.31¢. That is average revenue per kilowatt-hour, not a commission order. No 2025–2026 order for this utility was retrieved for this page. A separate rider can still move a single month.
What bill assistance can Mon Power customers ask about?
LIHEAP is the federal program for home energy bills (https://www.acf.hhs.gov/ocs/programs/liheap). Mon Power may also offer an income-qualified discount, budget billing, or a medical baseline. The current offer, income cutoff, and how to apply need verification on the utility site and with the state LIHEAP office and Public Service Commission of West Virginia.
Are data centers why this bill went up?
Large computing load is raising U.S. electricity demand, and regulators can later recover new generation and wires costs from customers. EIA has not published a dollar line that isolates data centers on this utility's residential bill. That pass-through needs verification.
