How to Use the Industrial Electricity Bill Calculator
Unlike residential rates, industrial electric bills in the U.S. are typically built from two separate components: a demand charge based on your peak billed demand (kW), and an energy charge based on actual consumption (kWh). This calculator takes both rates plus your demand and usage figures and breaks down the bill into each component.
The demand charge is billed every month based on your peak demand regardless of total energy consumed โ it reflects the capacity the utility has to keep available for you. The energy charge scales directly with how much electricity (kWh) you actually use during the billing period.
Unlike Korea's single unified industrial tariff, there's no one national industrial electric rate in the U.S. โ every utility sets its own demand and energy charges, which also vary by state, rate class (small vs. large industrial), season, and sometimes time-of-use period. This calculator uses a simplified demand + energy structure for estimation; check your utility's actual published tariff or a recent bill for your real rate numbers.
The result here also excludes taxes, fuel adjustment charges, and other riders that many utilities add on top of base demand and energy charges, so your actual bill will typically come out somewhat higher than this estimate.
Frequently Asked Questions
The demand charge is a fixed monthly amount based on your peak demand (kW), billed regardless of how much energy you actually use. The energy charge is based on actual energy consumed (kWh). Most industrial rate structures bill both together.
Rates vary significantly by utility, state, rate class, and season โ there's no single national industrial rate in the U.S. Check your utility's published tariff sheet or a recent bill for your actual demand charge ($/kW) and energy charge ($/kWh).
