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
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.
