Just wrapped up my biggest single-facility recovery ever. Plastics manufacturer in Fort Wayne, IN served by I&M (AEP Indiana). They had 3 separate meters all with incorrect CT ratios in the billing system. Two were 200:1 billed as 400:1 (underbilling the utility) and one was 400:1 billed as 200:1 (overbilling the client). The net overcharge on the one meter more than offset the underbilling on the other two. Total recovery: $340,000 going back 4 years. Client is over the moon.
CT ratio error on 3 meters at same facility - $340K recovery
That's a career highlight Eugene. Three CT ratio errors at one facility is almost unheard of. Were they all installed at the same time? I'm wondering if the same electrician or utility crew made the same documentation error on all three.
Good question Jim. Two of the three meters were installed during a plant expansion in 2019. The third was original to the building from 2008. So it looks like the 2019 install crew documented the ratios wrong and nobody caught it. The 2008 meter error had been hiding for 16 years but the statute of limitations only let us go back 4.
This is exactly why every auditor should check CT ratios on every large commercial and industrial account. It takes 5 minutes to compare what's on the bill to what's on the meter nameplate and it's one of the highest-dollar errors we find. Great work Eugene.
