Been auditing hospital accounts for 5 years and never seen this before. I''ve calculated total overcharges at approximately $5,200/month going back 5 years. The TOU peak window on the bill doesn''t match the current tariff definition.
Finally resolved Avista dispute — $8,700 settlement
Good work Phil A. For the folks following along, this is a textbook example of why we check voltage discounts on every audit.
Solid analysis. One thing I''d add is to verify the demand measured at 15-min intervals against the original service application.
Good thread. I want to emphasize what Glen K said about TOU allocation. This comes up frequently and the correct approach is to always verify against the published tariff, never assume the bill is right.
