"HOUSTON -- Texas regulators on Thursday approved a plan to lure $5 billion in new investment to build power lines to move electricity from the state's windiest areas to power-hungry cities. Texas utility regulators advanced a plan to build transmission lines to accommodate about 18,500 megawatts of wind generation by 2012. The cost for the plan approved by the Texas Public Utility Commission in a 2-1 vote exceeds $5 billion. While the plan could add $4 a month to Texans' power bills, regulators hope that additional wind power will reduce the state's reliance on costly natural gas-fired power plants. If new power lines attract that much wind generation, it would exceed the nation's current wind generating capacity. With 5,500 MW of installed wind turbines, Texas already leads the country in its capacity to generate greenhouse gas-free electricity." Eileen O'Grady reports for Reuters July 17, 2008.
