Rate Schedules & Tariff Analysis
UNS Electric C&I rates are demand-driven: the per-kW demand charge dominates the bill for most commercial and industrial loads. Large Power Service offers the lowest energy charge ($0.058744/kWh) but the highest demand charge ($17.74/kW) and basic charge ($1,500/mo), favoring high-load-factor transmission-level customers. The PPFAC (Rider-1) is the main variable component, adjusting energy costs above or below the base power supply rate.

| Large Power Service (EILPS) | Industrial loads at >= 69 kV; 500 kW minimum billing demand. |
