Client has 15 locations across Ohio served by different FirstEnergy companies - Ohio Edison, CEI, and Toledo Edison. Found systematic demand billing errors where the billed demand is higher than the actual recorded demand. Affects about 8 of the 15 locations. FirstEnergy claims their billing is correct.
FirstEnergy Ohio multi-site demand billing errors
FirstEnergy Ohio has been having billing system issues since their merger integration. Get copies of the actual meter demand records and compare them line by line to the billed amounts. Document everything.
I've seen this with FirstEnergy. Sometimes they bill ratchet demand when the tariff doesn't call for it, or they use wrong demand multipliers. Check the rate schedules carefully for each location.
File formal disputes with supporting meter data. FirstEnergy Ohio usually resolves these quickly once you provide documentation. The key is getting the actual interval demand readings from the meters.
