Interesting development with my Oncor dispute. We pulled 18 months of billing history and found the voltage discount missing started in 2012. The TOU peak window on the bill doesn''t match the current tariff definition.
Client in Memphis — National Grid billing period overlap for 4 years straight
Be careful with Entergy''s refund process — they sometimes try to limit the lookback period to 3 years.
Good thread. I want to emphasize what Elmer R said about demand charges. This comes up frequently and the correct approach is to always verify against the published tariff, never assume the bill is right.
