Illustrative summary — the filed tariff is always the governing document.

| R-1 — Residential | Residential multifamily buildings using district energy for heat and hot water | Metered use with seasonal pricing that reflects winter demand |
| B-2 — Large Commercial | Large buildings and campuses with high, steady loads | Demand and usage charges tailored to large-volume service |
How District Energy Is Billed
By the megawatt-hour
District energy is metered in megawatt-hours of thermal energy (MWht) delivered. Your bill combines a fixed service charge, usage charges that vary by season, and a fuel-cost adjustment that passes through the actual cost of producing thermal energy without markup.
Winter usage typically dominates annual cost for heating customers, which is why demand-reducing upgrades — controls, traps, insulation — pay back quickly.
