  1. Texas Wind Energy American Meteorological Society Summer Community Meeting – Norman Oklahoma Henry Durrwachter, P.E. August 12, 2009

  2. Installed Wind Capacity

  3. Electric Reliability Council of Texas (ERCOT) • The only intra-state electric grid in the U.S. • 3 Direct Current (DC) ties to the Eastern Interconnect (2) or Mexico (1) • Serves about 20 million customers (85% of Texas load) over 200,000 sq. miles of territory (75%) • 38,000 miles of high voltage transmission lines (345 kV, 138 kv and 69 kV) • Non-profit organization regulated by the Public Utility Commission of Texas (PUCT) Graphic courtesy of ERCOT

  4. ERCOT Reserve Margin and Energy Mix 2008 • 169 generating plants (72,500 MW of capacity at peak) • 2008 Peak demand = 62,174 MW • 16.6% Reserve Margin* (12.5% minimum) • 580+ thermal generation units • Over 8,000 MW of wind generation *Estimated 309 Million MWh

  5. Installed Wind Generation in Texas 8,290 MW Installed as of 12-31-2008 31 33 In ERCOT Outside ERCOT

  6. Monthly Energy Production – West Texas Wind Farm

  7. Peak Load Hour 11.7% ERCOT Summer Peak Month Coincidence (Hourly Average) - 2008

  8. High ramp rates Hourly Variability of Wind January 5, 2007 – Total Installed Wind Capacity = 2,790 MW

  9. Scenario 2 - 18,456 MW of Wind - $4.93 Billion Miles of New ROW: 345 kV = 2,334 138 kV = 42

  10. Questions Q: What is the proper role for government, industry and academia? • Government – provide access to appropriate weather data • Industry – willingness to utilize the latest tools and techniques to better forecast wind energy production • Academia – research better ways to forecast wind energy production Q: What are the primary knowledge gaps? • Correct modeling and forecasting of low-level jets and their impact on wind generation production (according to our staff meteorologist) Q: How can all parties leverage their expertise to move the nation forward to improve the adoption of renewables? • Learn from others’ experiences • Recognize the shortcomings of renewable technologies (variable fuel supply, non-dispatchability) and • create innovative methods, procedures or incentives to address those shortcomings through new or existing generating technologies or control systems.
