-- AMSC"s HTS Wire, Motor and Wind Turbine Design Strengths to be Coupled with Advanced Stator Technology and Manufacturing Expertise from TECO-Westinghouse
-- National Institute of Science and Technology to Fund Development of Technologies for 10 Megawatt-Class, Direct Drive Offshore Wind Generators Powered by HTS Wire
WESTBOROUGH, Mass. & ROUND ROCK, Texas----American Superconductor Corporation, a leading energy technologies company, and TECO-Westinghouse Motor Company (TWMC), a leading manufacturer of motors and generators, announced today that they have formed a research joint venture to develop high temperature superconductor (HTS) and related technologies for high-power, direct drive wind generators for offshore wind farms.
Direct drive wind generator systems utilizing HTS wire instead of copper wire for the generator"s rotor are expected to be much smaller, lighter and more efficient than conventional generators and gearboxes. The net effect is expected to be a lower cost of wind generated electricity, particularly for offshore wind farms. AMSC and TWMC also announced that they have received an award from the National Institute of Science and Technology"s (NIST) Advanced Technology Program (ATP), which is providing $3.4 million in funding toward the $6.8 million research project to be conducted under the joint venture.
"The objective of the TWMC-AMSC research joint venture is to develop technologies that will enable the deployment of offshore 10 megawatt class, direct drive wind generators - double the power capacity of conventional systems," said AMSC founder and chief executive officer Greg Yurek. "The result will be more power delivered from each offshore wind turbine, which would significantly reduce the total costs of offshore wind farms. This advanced system will provide a powerful option for our Windtec customers and others who want to capitalize on the rapid growth of the offshore wind market."
According to BTM Consult ApS, the installed base of offshore wind generated electricity at the end of 2006 was approximately 877 megawatts (MW), representing approximately one percent of the world"s wind power capacity. By 2011, BTM predicts this figure will increase to 7,606 MW, representing eight percent of wind power capacity worldwide. Research firm Douglas-Westwood expects there will be $11.8 billion in offshore wind power capital expenditure over the next five years.
"HTS technology provides a new, powerful option for enabling large-scale offshore wind farms," said Dr. H.C. Meng, President, TWMC. "Our wind generator business is growing rapidly, and today"s turbine manufacturers are increasingly focusing on offshore locations and higher power systems. Our research joint venture with AMSC gives us the opportunity to expand our product offerings in the global wind energy market."
Wind generators up to 5 MW are now being sold commercially on the market. However, higher power systems have not been introduced due primarily to generator weight and cost limits.
Lower weight HTS direct drive generator systems are expected to provide more power in a smaller package for about the same cost as conventional direct drive generators. By replacing copper with HTS on the generator"s rotor and utilizing a new high-efficiency stator design to be developed under this project, AMSC and TWMC estimate that they could produce 10 MW class direct drive generator systems that would weigh approximately 120 metric tons, or about one-third the weight of conventional direct drive generators with this power rating. Technically, weight reductions could be greater, albeit at a higher cost, giving wind energy system manufacturers and developers new options to design and deploy cost-effective offshore wind farms.
The 30-month cost-shared research project to be conducted by the joint venture with NIST funding calls for the development of new HTS wire and coil technologies that will help enable the design and manufacture of 10 MW class, direct drive AC synchronous generators for off-shore wind turbines. The targeted ultra-low-speed, high torque generators are expected to produce full power at 6 kilovolts at 11 revolutions per minute.
