Just ran into an interesting situation with Austin Energy in Tacoma. We pulled 36 months of billing history and found the service voltage issue started in 2020. The TOU peak window on the bill doesn''t match the current tariff definition.
Alliant Energy Rate I-5 misapplication — $31,500/month impact
This is exactly why I always pull 48+ months of history. The pattern wouldn''t show in a shorter window.
