Learn how commercial electricity bills work — demand charges, time-of-use (TOU) energy rates, and ratchet clauses — and how battery energy storage systems can be sized and operated to minimize commercial energy costs.
Commercial electricity bills have two primary components that residential customers don't typically see:
Energy Charges — charges for the total kilowatt-hours (kWh) consumed, often in a time-of-use (TOU) structure where energy consumed during on-peak hours (e.g., 2–9 PM on weekdays) costs 2–4× more per kWh than energy consumed during off-peak hours.<
