Directional reads like this describe the listed inventory, not a prediction of future prices.

Data caveats
- Figures are unweighted averages of 4 weekly snapshots of the publicly listed residential inventory; a week belongs to the month containing its Monday, and months with an ingest gap average fewer snapshots. The weekly detail table above is the complete set behind this report.
- Averages describe listings, not enrollments — a plan listed all month counts the same whether one household or ten thousand chose it, and offers sold only through provider channels aren't captured.
- Month-over-month comparisons use the same method for both months. Structure shares (bill credits, minimum-usage fees, free periods) reflect what our EFL parsing detected on listed plans.
Figures reflect plans as listed during September 2026 and are historical records, not current offers. Estimated costs depend on usage, TDSP territory, plan terms, and availability. Users should confirm final pricing and terms with the provider before enrolling. TrueBill Energy is a free comparison tool and does not sell electricity or enroll customers.
