The Public Utility Commission of Texas (PUC) selected a transmission scenario that will eventually transmit a total of 18,456MW of wind power from West Texas and the Panhandle to metropolitan areas of the state.

The PUC selected scenario 2, which is estimated to cost US$ 4.93 billion, or approximately US$ 4.00 per month per residential customer once construction is complete and costs are reflected in rates. It is expected that the new lines will be in service within four to five years. Earlier this year, the Electric Reliability Council of Texas (ERCOT), the agency which oversees the state's electric grid, responded to a PUC order to provide several scenarios to the commission. The four scenarios contained a total of 12,053, 18,456, 24,859, and 24,419MW of installed wind generation distributed among five Competitive Renewable Energy Zones (CREZs) in West Texas and the Texas Panhandle. Senate Bill 20, which the state legislature passed in 2005, directed the PUC to select the most productive wind zones in the state and devise a transmission plan to move power generated from these zones to various populated areas in the state.
