Breakthrough, low-cost wind turbine technology moves closer to commercialization

The Wind Turbine Company (WTC) has been awarded an $800,000 contract with the U.S. Department of Energy’s National Renewable Energy Laboratory (DOE, NREL) to continue prototype testing and development of the company’s WTC 750 kilowatt wind turbine. “Our new wind turbine technology provides the potential to reduce wind electricity cost by approximately one-third,” said Larry Miles, President of the Wind Turbine Company. Prototype testing will occur at the DOE’s National Wind Technology Center at NREL, which also will provide technical assistance on the project. Hamilton Sundstrand Corporation, a subsidiary of the United Technologies Corporation, has been awarded a subcontract to support WTC in its turbine development efforts.”The absence of new wind project development in the U.S. so far this year clearly illustrates there is a compelling need for a wind turbine that does not require on going operating subsidies in order to compete in the electricity marketplace,” noted Miles. He added, “We are very close to delivering our break-through wind turbines to the commercial market.”WTC’s 750 turbine features 2 rotor blades, oriented on the downwind side of the tower. This design has long been recognized as having the potential to significantly reduce the cost of wind-generated electricity. Under a previous contract with NREL, and with additional support from the California Energy Commission, WTC built and tested two prototypes, the first rated at 250 kW, the second at 500 kW. The current contract is focused on optimizing the design and preparing the new machine for the commercial marketplace.Hamilton Sundstrand brings aerospace control system, rotating machinery and rotor blade expertise to the effort. Hamilton Sundstrand can also draw on the vast technical resources found in sister companies of UTC including Sikorsky and Pratt & Whitney as well as its parent’s United Technologies Research Center. Hamilton Sundstrand has previously provided WTC with technical support.

About WTC

The Wind Turbine Company was formed in 1990 to design and manufacture wind turbines capable of producing unsubsidized electricity at prices a third less than current manufacturers. WTC is headquartered in Bellevue, Washington. Additional information about WTC and its wind turbine technology can be found on the company’s web site at:

NREL is the U.S. Department of Energy’s premier laboratory for renewable energy research and development and a leading laboratory for energy efficiency R&D. NREL is operated for DOE by Midwest Research Institute and Battelle.
