Interesting development with my ComEd dispute. Sales tax is being charged even though the client has a valid exemption certificate on file. Compared the interval data against the bill and found a 15% variance in peak demand.
State-by-state backbilling limits reference?
Had the exact same problem with Salt River Project last year. Took about 18 months to resolve but got full refund.
Solid analysis. One thing I''d add is to verify the seasonal rates apply May-October against the original service application.
Dean G, what was the client''s reaction when you showed them the $112,000 overcharge?
I''d recommend requesting the meter test records from Southern California Edison. That''s what cracked my case open.
