Found something odd at a plastics manufacturer in Ohio on AEP's GS-2 rate. They're clearly running three-phase equipment but getting billed as single-phase. Demand charges are way too low and there's no three-phase service charge. How do I approach AEP about this without creating a huge back-billing situation?
Three-phase billing error at plastics plant
That's a tough spot Lee. If they're actually getting three-phase service but billed as single-phase, AEP will definitely want to true up once they discover it. The service charge difference alone could be significant. I'd document everything carefully before contacting them and try to negotiate a limited lookback period.
You're right Ken. Looking at the meter setup, it's definitely three-phase service with a single-phase billing multiplier. This could be a $50K+ correction going back several years. Client is going to freak when they find out.
