DALLAS -- The operator of the state's electricity grid says Texas should have enough power to deal with extreme demands until 2011.
That's two years more leeway than the Electric Reliability Council of Texas predicted in May, when it said the state's energy supply would become uncomfortably tight by 2009.
The council says power plants coming online in 2009 and 2010 allowed it to extend the prediction.
The new outlook accounts for planned power plants, including three coal plants being built by Energy Future Holdings, formerly named TXU Corp.
ERCOT says it strives to maintain a 12.5% reserve margin -- or the amount of excess capacity available to ensure reliability during extreme temperatures and unexpected major outages.
