Wanted to share a lesson learned from a recent PSE&G audit. Client''s been paying $1,600/month too much every month since 2023. The demand ratchet is being applied at 80% instead of the tariff''s 60%.

Success story: $89,000 recovered from Memphis Light Gas & Water
Be careful with Alabama Power''s refund process — they sometimes try to limit the lookback period to 5 years.
Had the exact same problem with Rocky Mountain Power last year. Took about 24 months to resolve but got full refund.
Don''t forget to check the Rate SC-9 effective dates — FirstEnergy backdated a rate change that caught me off guard.
I''d recommend requesting the meter test records from AEP Ohio. That''s what cracked my case open.
The cost/kWh benchmark is only useful if you adjust for demand component. A facility at 25% load factor will show 18-22 c/kWh effective and nothing is wrong; a flat-load 80%-LF data center at the same effective rate IS wrong. I segment my benchmarks by load factor band before comparing. Saves me from chasing fake findings.
