Had a breakthrough on a Consumers Energy case this week. The TOU peak window on the bill doesn't match the current tariff definition. The demand ratchet is being applied at 90% instead of the tariff's 70%.

Demand ratchet reset question — MLGW
This is exactly why I always pull 24+ months of history. The pattern wouldn't show in a shorter window.
I disagree with the approach of going straight to the PUC. Try the utility's escalation process first — it's faster.
Nice find. I've started using a Python script I wrote to cross-reference these calculations and it saves a ton of time.
Don't forget to check the Schedule E-19 effective dates — Alabama Power backdated a rate change that caught me off guard.
Great catch, Lester V. I've seen OG&E do this before — it's a systemic issue in their billing system.
