Taxes versus riders versus base rates
Base rates cover energy, demand, delivery, and customer charges approved in rate cases. Taxes include sales tax, gross receipts tax, or utility user tax depending on municipality. Riders are tariff amendments—often labeled with acronyms—that recover specific programs, fuel adjustments, storm costs, or energy efficiency surcharges.
For laundromats where utilities represent roughly 20–25% of revenue nationally per CLA due diligence materials, unnoticed rider stacking materially affects margin even when vended load is flat.
| Type | Typical label | Driver |
|---|---|---|
| Municipal franchise fee | Franchise fee | City agreement with utility |
| Sales tax | State/local tax | Taxable utility service |
| Policy rider | RPS, EE surcharge | Legislative program funding |
| Cost recovery rider | Storm, fuel adjustment | Regulatory approved recovery |
| Credit rider | Credit or refund line | Settlement or overcollection return |
Electric versus gas bill placement
Electric bills in Texas REP markets may show supply taxes separately from TDU delivery riders. Gas LDC bills under Railroad Commission oversight in Texas stack delivery, commodity, and tax lines differently from Atlanta Gas Light marketer statements.
Always sum electric and gas taxes/riders when responding to CLA survey concerns about utility expense—owners often analyze kWh alone and miss rider rows.
Procurement and riders
Shopping supply in eligible territories per EIA changes competitive energy price—not necessarily state-mandated riders on delivery. Fixed supplier contracts may still pass through statutory charges defined in the contract fine print.
Distinguish procurement (supplier price) from consumption (fewer kWh) from regulatory surcharges (riders)—three separate levers on the same total due.
Tracking framework
Build a rider register when investigating why-a-bill-increased questions.
- Copy each rider line label and amount monthly into a ledger.
- Note regulatory docket or notice number when mailed.
- Compute rider $ as percent of pre-tax subtotal to spot outliers.
- Compare same month year-over-year before blaming equipment.
- Ask utility whether rider is temporary with sunset date.
- Include rider history in 1–3 year bill archives for due diligence.
