Equal Payment Plan (EPP) Gas Bill Guide — What It Is and When to Dispute: bill spike and estimated read review
EPP spreads your estimated annual gas cost into equal monthly payments. Each month you pay the same flat amount regardless of actual usage. At year-end, the utility reconciles the difference — if you underpaid through the year, the catch-up charge can be large. This guide shows how to verify both your monthly installment and the reconciliation calculation.
Key fields to verify
- Scheduled EPP payment amount
- Actual usage charges this month
- Cumulative EPP balance (under/over payment)
- Year-end reconciliation date
- Annual usage estimate used to set EPP amount
- Rate used in EPP calculation
Risk signals worth questioning
- Monthly EPP payment is more than 2× your summer actual charges
- Year-end reconciliation bill is more than 30% above your normal EPP amount
- Utility used an outdated annual estimate to set your EPP rate
- Reconciliation period does not match your EPP start date
Dispute-prep checklist
- Compare each month's EPP payment to actual charges — note the monthly gap
- Sum all monthly gaps to verify the year-end reconciliation amount
- Ask your utility for the annual usage estimate used to set your EPP rate
- If estimate is more than 20% off from your actual annual usage, request a rate adjustment
