Transcription notes recorded when this tariff was encoded, including anything deliberately left out.
THE RIDER SUMMARY IS NOT THE WHOLE ADDER. Leaf No. 99 prints a TOTAL and the components reconcile to it exactly, but Schedule RS separately names charges that are not in that total and says they are added to the bill. This tariff was first encoded without them. Reconciling to a printed total proves the components of that total and nothing more.
The rider factors as filed already include revenue-related taxes and regulatory fees, and both leaves say so, so no further tax uplift is applied here. Sales tax and municipal fees are added by the utility on top and are not part of the tariff.
THE DEFAULT RESIDENTIAL RATE in Duke Energy Carolinas' South Carolina territory, and structurally unlike the North Carolina one on the same operating company: TIERED at 1,000 kWh a month rather than flat, five riders rather than twelve, a different commission and unrelated leaf numbering.
THE TIER IS INVERTED - the second block costs MORE, not less. First 1,000 kWh a month at the lower rate, everything above it at the higher one.
THE STORM CHARGE IS BIGGER THAN EVERY RIDER COMBINED: 0.4583 c/kWh against a rider TOTAL of 0.2504. It is not in the rider summary. Leaf No. 101 is explicit that these rates 'are not included in the MONTHLY RATE provision of the applicable schedule used in billing and shall therefore be added'.
SOUTH CAROLINA HAS NO FUEL RIDER, and that is not an omission. Leaf No. 11 says the cost of fuel, variable environmental cost, PURPA avoided capacity and DERP avoided cost 'is incorporated as a part of, and will apply to all service supplied under, this Schedule', and Leaf No. 50C confirms these are 'recoverable in base rates' - it prints them as F1..F5 totalling 2.8854 c/kWh for residential, already inside the 13.8125/14.4661 figures. North Carolina by contrast bills fuel as two separate riders. Adding an SC fuel component would double-count it.
Eight residential schedules (RS, RE, ES, RT, RB, R-STOU, RSTC, RETC) share the rider total on SC Leaf No. 99 - a different set from North Carolina's six. Only RS is encoded.
The Minimum Monthly Charge is the Basic Customer Charge, $11.96. It can never bind, because the encoded fixed charge is $12.48 once DERP is included, so it is recorded here and not encoded as a separate floor.
NOT ENCODED: sales tax, municipal service agreement fees and business licence fees, which Leaf No. 11 says are added to the charges determined above. They are jurisdiction-specific.
