Well, luckily, everything is not bigger in Texas, especially electricity rates. Our study of Dallas electricity rates shows that folks who live in the Dallas suburb of Plano pay some of the lowest electricity rates in Texas. Based on EIA (Energy Information Administration) data. The average electricity rate paid in the US is 10.27¢/kWh while the average rate for electricity in Plano, Texas is 8.12¢/kWh - that??™s a 26% difference. The following rates include TDSP (Transmission and Distribution) charges from Oncor, which reflect the “All in” cost of electricity and makes it easy to compare electricity plans side by side.
