Rates vary by utility, usage tier, e time of use.

Tiered e Tempo-of-Usar Rates

Tiered Pricing

Muitos utilities charge diferente rates based on usage levels:

Tier 1 (0-500 kWh): $0.10/kWh
Tier 2 (501-1000 kWh): $0.15/kWh
Tier 3 (1001+ kWh): $0.25/kWh

Higher usage = higher rates for additional energy.

Tempo-of-Usar (TOU) Pricing

Rates change based on time of day:

Off-peak (night): $0.08/kWh
Mid-peak (morning/evening): $0.15/kWh
On-peak (afternoon): $0.30/kWh
