Had a breakthrough on a NIPSCO case this week. Compared the interval data against the bill and found 3 months of missing interval data. We pulled 24 months of billing history and found the demand reset failure started in 2017.
Client in Bismarck — CenterPoint Energy seasonal rate misapplication for 3 years straight
Solid analysis. One thing I''d add is to verify the seasonal rates apply May-October against the original service application.
I''d recommend requesting the meter test records from Southern California Edison. That''s what cracked my case open.
Excellent discussion everyone. Diana R, your approach on this CPS Energy case is solid. For newer members, this is a great example of why thorough tariff review is essential.
