Lines built for Texas wind power help supply Permian oil patch
* Electricity needs for oil, gas production strain grid
* Wind lines near completion as West Texas oil activity soars
* New wind lines designed for more wind-farm development

HOUSTON, Oct 25 (Reuters) - High-voltage transmission lines being built to carry electricity from wind farms in West Texas to the state's major cities are instead helping power the boom in oil exploration and production in the Permian Basin, according to a company serving the region.
Owing to the use of hydraulic fracturing and horizontal drilling to unlock oil and natural gas resources, electric demand in the prolific Permian Basin - which stretches from West Texas into New Mexico - has been growing 5 to 6 percent a year, said officials with Oncor, the Dallas-based transmission company that serves much of the Texas Permian.
That's more than twice the growth rate for electricity seen across Oncor's north Texas system that includes Dallas and Fort Worth, said Jim Greer, Oncor's chief operating officer.
In addition to having a long history as one of the country's largest oil and gas producing regions, West Texas has seen a surge in wind generation that propelled the state to No. 1 in the nation with 10,570 megawatts of wind capacity. Texas is also the top power producer and consumer in the United States.
The growth of wind farms initially created congestion on the existing power grid as electricity was unable to move to power-hungry cities like Dallas, Austin and San Antonio. Continued...
