EIA Form 923 + Form 861
Methodology
The calculation combines two EIA datasets. Form 923 provides monthly gas procurement costs and volumes. Form 861 provides annual residential customer counts. Dividing annual above-peer procurement cost by residential customer count produces the per-customer figure. The per-household figure represents the residential customer's proportional share of above-peer procurement costs — in rate case proceedings, precise customer impact requires a full revenue requirement and cost allocation analysis.

Analysis — Year-over-Year Per-Customer Gas Cost Changes
This tab translates annual gas procurement cost changes into per-household terms. South Carolina Public Service Authority cut per-customer gas costs by 52% from 2023 to 2024. Entergy Mississippi's +$11.97/month increase is particularly notable because Mississippi Power — in the same state — was the national best performer. Two utilities in the same state with dramatically different procurement outcomes is the most powerful argument for procurement performance auditing.
