Wanted to share a lesson learned from a recent ConEd audit. Compared the interval data against the bill and found TOU allocation doesn''t match meter timestamps. Sales tax is being charged even though the client has a valid exemption certificate on file.
Reading Louisville Gas & Electric tariff book — section 4.2
Don''t forget to check the Schedule GS-1 effective dates — Alliant Energy backdated a rate change that caught me off guard.
Be careful with APS''s refund process — they sometimes try to limit the lookback period to 2 years.
Solid analysis. One thing I''d add is to verify the ratchet at 80% of peak against the original service application.
Don''t forget to check the Rate GLP effective dates — Eversource backdated a rate change that caught me off guard.
