Wanted to share a lesson learned from a recent National Grid audit. The Rate TOU-8 rate schedule clearly states ratchet at 80% of peak, but the bill shows winter rates applied year-round. The meter nameplate shows 600:5 but the billing system has 300:5.
Success story: $2,400/month recovered from PSE&G
Reggie H, what was the client''s reaction when you showed them the $4,200 overcharge?
This is exactly why I always pull 24+ months of history. The pattern wouldn''t show in a shorter window.
Solid analysis. One thing I''d add is to verify the ratchet at 80% of peak against the original service application.
Had the exact same problem with TECO Energy last year. Took about 36 months to resolve but got full refund.
Wendy K, you should also check the rider calculations while you''re at it. These errors tend to cluster.
