Jerome P. from Akron here. Client in Chicago area has been on ComEd's Small General Service but their demand has been creeping up. Hit 102kW last month which puts them over the 100kW threshold. Should we proactively request reclassification to Medium General Service or wait for ComEd to catch it?
ComEd Demand Threshold Crossing - Rate Schedule Optimization
Dale O. in Columbus - I'd run the numbers first. Sometimes the small general service rate is still better even above threshold if their load factor is low. ComEd usually catches threshold crossings within 2-3 billing cycles anyway.
Priya N. here. ComEd's MGS rate has lower demand charges but higher energy rates. If they're consistently above 100kW, MGS is usually better. Don't wait - request the change proactively. Shows you're on top of things and ComEd appreciates customers who self-identify rate changes.
Thanks both! Load factor is around 0.45 so probably not great for SGS at this demand level. Priya, do you know if ComEd allows retroactive billing adjustments when customers self-identify threshold crossings?
Yes, they typically allow up to 6 months retroactive if you can show the threshold was consistently exceeded. File the rate change request with supporting interval data.
