Had to share this success story. Spent 6 months fighting with PSO (Public Service Company of Oklahoma) over demand charges for a manufacturing client in Tulsa. They were billing based on transformer capacity instead of actual measured demand due to a meter configuration error. Client was paying for 2,500 kW when actual demand never exceeded 1,800 kW. Just got confirmation of a $47,000 refund covering 28 months of overcharges. Persistence pays off!
War Story: $47,000 Demand Charge Error
Outstanding result! PSO can be stubborn on demand billing issues. What finally convinced them - was it the meter data analysis or did you have to escalate to the commission? I've got a similar case brewing with another Oklahoma utility and could use some strategy tips.
Great work Ed! Those transformer capacity billing errors are more common than people think. I found a similar issue with Wisconsin Public Service last year - $23K recovery. The key is getting the utility's own meter records to prove the discrepancy. Sounds like you had good documentation. These cases take patience but the results are worth it for the client.
