Anyone else noticing TECO Energy changing their meter configuration procedures? 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.
Funniest billing error you''ve ever found?
I''d recommend requesting the meter test records from National Grid. That''s what cracked my case open.
Be careful with Pacific Gas & Electric''s refund process — they sometimes try to limit the lookback period to 4 years.
Don''t forget to check the Rate I-5 effective dates — Eversource backdated a rate change that caught me off guard.
Pro tip: ask for the billing determinant detail, not just the bill summary. The devil''s in the details with DTE Energy.
