Just ran into an interesting situation with Georgia Power in Albuquerque. The TOU peak window on the bill doesn''t match the current tariff definition. Compared the interval data against the bill and found TOU allocation doesn''t match meter timestamps.
Heads up: Appalachian Power changed their demand charges policy
Pro tip: ask for the billing determinant detail, not just the bill summary. The devil''s in the details with Eversource.
