How Rocky Mountain Power’s plans work
Schedule 2 (Residential Service). One price per kWh at every hour, all year: 11.5¢. Shifting use to other hours changes nothing on this plan; using less is the only lever. Fixed charge: $24.24 a month.
Schedule 19 (Residential Time of Use (pilot)). Peak 7 am–9 am, Peak 5 pm–11 pm on July weekdays; 8 of 24 hours carry the top price of 15.4¢. The cheapest July weekday hour costs 9.2¢, so moving 1 kWh out of the top hours saves 6.2¢. January weekdays range from 9.2¢ to 15.4¢. Fixed charge: $26.30 a month.
Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.
As a cross-check, Rocky Mountain Power billed its residential customers an average of 15.13¢ per kWh in 2025 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for Wyoming’s price change since.
