Just ran into an interesting situation with Puget Sound Energy in Arlington. Compared the interval data against the bill and found TOU allocation doesn''t match meter timestamps. We pulled 12 months of billing history and found the rate classification error started in 2012.
DTE Energy Rate GST misapplication — $3,100/month impact
Don''t forget to check the Schedule LPS effective dates — Rocky Mountain Power backdated a rate change that caught me off guard.
Deborah T, you should also check the demand charges while you''re at it. These errors tend to cluster.
Great catch, Bob W. I''ve seen Eversource do this before — it''s a systemic issue in their billing system.
