This plan's 12-month term would run roughly November 2026 to October 2027.

Kilowise read this plan's own Fact Sheet formula as an all-in $4.06/month fixed charge (REP base charge plus TDU delivery, combined) plus 11.992¢/kWh (REP energy charge plus TDU delivery, combined), the same formula behind the estimate above. It has no usage-threshold credits, so no bill-credit cliff.

Among the 153 fixed-rate Oncor plans available right now, this one's rate is in the cheapest quarter. Compared at each plan's price across a range of household usage, not at one point a bill credit could be tuned around.
