Distribution in the delivery stack
After transmission moves bulk power, distribution utilities step voltage down and feed your panel. For a laundromat running CLA's mean 16.6 hours per day, that local network must support continuous lighting, washer loads, and HVAC. Distribution tariffs recover capital and maintenance for that local grid through kWh, kW, and fixed components.
Oncor describes delivery charges as regulated TDU costs distinct from competitive supply—distribution is the local portion of that delivery stack.
| Bucket | What it pays for | Laundromat example |
|---|---|---|
| Supply | Energy commodity | kWh for water heat and lighting |
| Transmission | Bulk lines | Regional grid fees |
| Distribution | Local wires and transformers | Demand kW, customer charge |
| Taxes/riders | Policy surcharges | Franchise fees, program riders |
Demand and distribution
Interval demand charges—15 minutes on Oncor-style tariffs or 30 minutes on Pepco DC GSLV examples—are implemented through commercial distribution rate schedules. A peak when washers and electric water heating align sets billed kW even if gas dryers handle drying therm separately.
Effective $/kW from demand line items describes distribution capacity pricing for that month, not supply $/kWh.
What changes when you switch supplier
EIA notes utilities continue delivering in choice states. Changing REP or supplier alters supply lines only. Distribution charges update through TDU rate cases and riders—visible on bills regardless of who sells you kWh.
Virginia typical stores face limited electric choice; Georgia laundromats often see bundled distribution and supply on one regulated bill—format differs, but distribution remains regulated.
Owner action list
Separate distribution from supply before budget meetings.
- Extract distribution subtotal ÷ kWh for delivery-only trend line.
- Track billed kW against tariff threshold (e.g., Oncor >10 kW note).
- Read TDU rider notices—not REP marketing—for distribution updates.
- Call TDU for outages and meter issues; call REP for supply contract terms.
- Include distribution trends in CLA-style 1–3 year bill packets for buyers.
