Need some experienced eyes on a Xcel Energy billing issue. We pulled 36 months of billing history and found the estimated billing started in 2016. I've calculated total overcharges at approximately $196,000 going back 3 years.

State-by-state backbilling limits reference?
I disagree with the approach of going straight to the PUC. Try the utility's escalation process first — it's faster.
Don't forget to check the Rate GLP effective dates — TVA backdated a rate change that caught me off guard.
Don't forget to check the Rate SC-9 effective dates — MLGW backdated a rate change that caught me off guard.
Pro tip: ask for the billing determinant detail, not just the bill summary. The devil's in the details with Oncor.
