Rate Schedules & Tariff Analysis
For NSP-WI C&I accounts, demand charges dominate the bill once monthly demand exceeds 25 kW. Above 200 kW on Large General Time-of-Day Service, taking service at higher voltage (primary or transmission) earns energy discounts of 2.0% to 10.0% and lower demand charges, so metering voltage and load-factor management are the biggest levers. Time-of-day energy spreads are wide (on-peak summer ~$0.085/kWh vs off-peak ~$0.050/kWh on large service), rewarding load shifting.
Northern States Power Company - Wisconsin (Xcel Energy) Rate Schedule List
| Schedule | Applicability |
|---|---|
| Small General Service (Cg-1) | Non-residential under 25 kW |
| General Time-of-Day Service | Demand 25-200 kW |
| Large General Time-of-Day Service | Demand 200 kW or more |
| General Service (Gas) | Non-residential firm gas |
