Working on a Duke Energy audit and found they're applying summer rates in May but the tariff says summer season starts June 1st. Client is getting billed almost $3,000 extra per month. How carefully do you all verify seasonal rate transition dates? This seems like a systemic billing system error.
Seasonal rate schedule transitions - timing is everything
Gina, that's a great catch! Duke has had issues with seasonal transitions before. I always verify the exact dates in the tariff vs what's on bills. Some utilities use billing periods vs calendar months which creates confusion. Make sure you're comparing apples to apples - is it service period dates or bill period dates?
Chuck's point about billing vs service periods is critical. I've seen utilities argue that if the bill is issued in summer, they apply summer rates even if most of the service period was in spring. Always check the tariff language carefully - some say "bills rendered during" while others say "service provided during."
This is exactly why I create a calendar for every client showing when rate changes should take effect vs when they actually do on the bills. Gina, with Duke specifically, I'd also check if they're applying the right seasonal demand charges - sometimes the energy rates transition correctly but demand charges lag behind.
Randy's absolutely right about the regulatory leverage. Gina, did you find any other months where the transitions were off? If it's happening in May, I'd bet it's also happening at the fall transition back to standard rates. Could be a much bigger refund opportunity.
Mia's calendar approach is smart - visual tools really help catch these timing errors. Gina, if you can prove this is a systematic error affecting multiple customers, Duke's regulatory team will be very interested. They don't want state commission complaints about widespread billing system problems.
