How WPS’s plans work
Rg-1 (Residential Service). One price per kWh at every hour, all year: 14.9¢. Shifting use to other hours changes nothing on this plan; using less is the only lever. Fixed charge: $17.93 a month.
Rg5-OTOU (Residential Three-tier Optional Time-of-Use). Mid-peak 7 am–1 pm, Peak 1 pm–7 pm, Mid-peak 7 pm–10 pm on July weekdays; 6 of 24 hours carry the top price of 33.8¢. The cheapest July weekday hour costs 8.5¢, so moving 1 kWh out of the top hours saves 25.3¢. January weekdays range from 8.5¢ to 33.8¢. Summer pricing applies May–Sep; winter pricing Oct–Apr. Weekends differ: off-peak all day. Fixed charge: $17.93 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, WPS billed its residential customers an average of 17.20¢ 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 Wisconsin’s price change since.
