Had a breakthrough on a OG&E case this week. The TOU peak window on the bill doesn''t match the current tariff definition. Sales tax is being charged even though the client has a valid exemption certificate on file.
TOU window shifted — TECO Energy didn''t notify
Be careful with CenterPoint Energy''s refund process — they sometimes try to limit the lookback period to 3 years.
Pro tip: ask for the billing determinant detail, not just the bill summary. The devil''s in the details with Alabama Power.

This is exactly why I always pull 12+ months of history. The pattern wouldn''t show in a shorter window.
