Wind in Texas only 8.7% reliable

Press release, March 29, 2007 -- ERCOT Response to U.S. Rep. Joe Barton:
With regard to renewable energy, ERCOT is proud to have more wind generation in its region than any other state in the nation. Currently, almost 3,000 MW of new wind generation is either under construction or publicly announced, in addition to the 3,000 MW already existing in ERCOT. A significantly larger amount of future wind generation is also under study. Wind energy is good, clean energy and should be used to the fullest of its capability. At the same time, wind does not blow at a constant level, and in Texas is often at a low level at the time of the peak electrical demand during summer afternoons. ERCOT studies the availability of wind generation using its historical wind generation data. Using 2006 data, ERCOT has determined that 8.7% of the installed wind capability can be counted as dependable capacity during the peak demand period for the next year. Conventional generation must be available to provide the remaining capacity needed to meet forecast load and reserve requirements.
(ERCOT [The Electric Reliability Council of Texas] manages the flow of electric power to approximately 20 million Texas customers.)
