Capacity Charges on Laundromat Electric Bills
Last reviewed 2026-09-12 by Jaken Energy editorial desk. Next review scheduled 2027-03-12.
Direct answer
A capacity charge recovers regional grid costs for ensuring enough generation capacity to serve peak system load. On some commercial electric bills—especially in markets with capacity auctions—it appears separate from kWh energy and kW demand lines. Laundromats may see capacity as a per-kW or embedded delivery component depending on utility and ISO rules.
Definition: Capacity charge
Capacity mechanisms vary by region. In PJM and similar markets, capacity prices reflect auctions and assigned obligations tied to peak contributions. Some utilities embed capacity in delivery riders; others break it out explicitly for large commercial customers.
Owners should not confuse capacity with demand: both may use kW units but reflect different grid cost drivers. Tariff sheets define how your laundromat's rate class treats capacity.
Laundromat example
A mid-Atlantic laundromat on a general service tariff sees a 'Capacity Charge' line based on coincident peak factors from prior summer, adding hundreds of dollars in months unrelated to that store's current kWh trend.
