Need some experienced eyes on a Pacific Gas & Electric billing issue. The meter nameplate shows 600:5 but the billing system has 200:5. Sales tax is being charged even though the client has a valid exemption certificate on file.

FPL TOU window misapplication on cold storage account — $12,400 overcharge
Had the exact same problem with Empire District Electric last year. Took about 12 months to resolve but got full refund.
Don''t forget to check the Schedule LPS effective dates — Alliant Energy backdated a rate change that caught me off guard.
I''d recommend requesting the meter test records from TVA. That''s what cracked my case open.
Pro tip: ask for the billing determinant detail, not just the bill summary. The devil''s in the details with CPS Energy.
