Wind power to light up vast portion of state

A 3,000-mile network of transmission lines designed to bring wind-generated power from West Texas to homes and businesses from Dallas to San Antonio should be fully operational by today, year's end.

"There is a vast amount of wind energy that will suddenly be accessible to cities across Texas," said Jeff Clark, executive director of the Wind Coalition, a nonprofit association focused on wind resources throughout the state and the Midwest.

Grid operators are on track to have switched on the last of the power lines developed as part of the Competitive Renewable Energy Zones initiative, a $6.8 billion effort that began in 2008.

These lines eventually will provide pathways for up to 18,500 megawatts of electricity to travel from thousands of turbines - each as tall as a football field is long - on the windswept plains around San Angelo, Abilene and Amarillo, the Texas Public Utility Commission reports.

The network also will encourage further development of wind resources, state power planners say. That is especially true in the Panhandle, they say, which had no power transmission link to the rest of Texas prior to completion of the new lines.

Texas already leads the nation in wind power with 7,960 turbines, each one with blades of 150 feet or more, capable of generating between 1 and 4 megawatts of electricity. One megawatt is enough to power 500 homes under normal conditions.

The state has capacity, under optimal conditions, to generate 12,000 megawatts, more than twice that of No. 2 producer California. The new transmission network expands the power grid enough to allow a 50 percent increase in capacity. That means more of the graceful, 300-ton turbines are likely to spin across the horizon.

The $6.8 billion price tag is nearly $2 billion higher than the 2008 estimates when construction began, mostly because it took 600 more miles than planned to navigate tricky terrain and to follow roads and fences rather than cutting directly through the properties of reluctant landowners.

Some environmentalists expressed concerns about the impact of the lines on sensitive bat and bird populations.

Several property owner groups also objected to the lines, particularly in the Hill Country, where groups such as the Save Our Scenic Hill Country Environment argued that the lines were unsightly and could lower property prices.

Texas ratepayers will see a fee of as much as $7 added to their monthly bills in the coming years to help cover the construction tab, PUC spokesman Terry Hadley said. Advocates for the lines say the economic and environmental benefits outweigh the costs.

"It is going to result in a net cost savings to ratepayers," said Glen Hodges, spokesman for renewable power company Pattern Energy. "This low-cost wind power that will come onto the grid will result in a reduction, the net effect should be a reduction in the overall bill."

The transmission lines initially will carry about 11,000 megawatts of power, with more than 7,000 megawatts in additional capacity planned in the coming years.

Supporters say the project already is turning wide-open spaces into economic powerhouses while building a renewable energy renaissance.
