Professional Experience

National Renewable Energy Laboratory, Director, National Wind Technology Center (1994-2008)

Prior to his appointment to Research Fellow, Dr. Thresher led the research and development for the Federal Wind Energy Program. Under his direction, the Center managed the development of advanced wind turbines with rotor diameters in excess of 90 meters and power outputs of several megawatts. In addition, Dr. Thresher had responsibility for the startup of the new Federal Waterpower Program, including the development of advanced hydrodynamics and aerodynamic models, structural, and electrical power analysis methods required to design innovative and more costeffective advanced wind turbines and ocean devices.

National Renewable Energy Laboratory, Director, Utility Systems Division (1993-1994)

When Dr. Thresher was promoted to manage NREL's Utility Systems Division, he worked with DOE upper management to secure use of a 280acre site at Rocky Flats and developed the National Wind Technology Center. As Director of the new facility, Dr. Thresher worked closely with DOE to make the Center a focal point for national wind research. He successfully partnered with the Sandia National Laboratory to collaborate with NREL on wind technology development initiatives that impacted R&D programs at both laboratories. He also created new codes, new methods of analysis for wind turbine testing and new methods to develop advanced research turbines. The wind turbines at the Center were tested according to international standards required by the commercial power industry throughout the world.

National Renewable Energy Laboratory, Manager, Wind Research (1989-1994)

By 1989, the DOE wind program had grown to $12 million with $8 million assigned to NREL. The wind program's focus shifted from research to development of new wind technology. To achieve this goal, NREL promoted Dr. Thresher to manage the wind research program and a staff of 35 employees. Dr. Thresher's group was responsible for the next generation wind turbine development and to precondition the wind power market for new commercialized technology. Dr. Thresher initiated development activities by fostering relationships with wind industry members that included Zond, Atlantic Orient Corporation, Kenetech, Advanced Wind Turbines, Inc., and Northern Power Systems. To build confidence in these new turbines and accelerate commercialization, an operational testing program was created to condition the market. The wind program was a success under the direction of Dr. Thresher, and by 1994, Dr. Thresher was directing more than 45 people and managing a budget of $20 million per year.

National Renewable Energy Laboratory, Principal Scientist (1984-1989)

Eighteen years ago, NREL sought out Dr. Thresher to help integrate NASA's large machine program that was phasing out of NASA and into the NREL wind program. He began as a Principal Scientist with technical oversight of 2030 employees and a $5 million program to establish codes, carry out analysis to prove the ability to predict performance and loads for wind turbines and research to determine the effects of atmospheric turbulence.

Oregon State University, Full Professor (1970-1984)

In his position as professor at Oregon State, Dr. Thresher demonstrated his abilities as a leader in research and development, and project management. In 1976, Dr. Thresher was asked to work for two years with DOE in Washington D.C. to manage the innovative wind turbine research project through an intragovernmental personnel loan program. The innovative wind research program was managed through the DOE wind program office and started with a $3 million budget and contracted about 10 researchers at various universities around the country.

In 1978, he returned to Oregon State to lead and direct the research efforts on the effects of turbulence on structural dynamics of wind turbines and developed new modeling techniques. He was a major contributor to the engineering analysis and development of advanced wind turbine configurations. In 1976, the Oregon State University and DOE recognized him for his research in structural dynamics and analysis of the dynamic response of wind turbines exposed to turbulence. He developed the original "flap code" that provided the starting point for the structural dynamic analysis models of wind turbines that are currently researched at NREL today.

At Oregon State, Dr. Thresher also served as Director of the Energy Research and Development Institute from 1981 to 1984. This position involved obtaining funding and directing energy research efforts for graduate students and professors.

Throughout his tenure at Oregon State University, Dr. Thresher focused his research on wind energy. He worked with local and regional utilities, NASA, Battelle National Laboratories and DOE to develop wind technology and to research wind energy systems. He directed research assistants and managed a small budget from DOE.
