1617 Cole Blvd, Golden, CO, 80401-3393, USA ABSTRACT The United States Department of Energy (DOE) Wind Energy Research Program has begun a new effort to develop wind technology that will allow wind systems to compete in regions of low wind speed. The sites targeted by this effort have annual average wind speeds of 5.8 m/s measured at 10-meter height. Such sites are abundant in the United States and would increase the land area available for economic development twentyfold. DOE has initiated a three-element approach through a competitive request for proposals. The three elements in the RFP include concept design, component development, and system development. This work will build on previous activities under the WindPACT Program and the Next Generation Turbine Program. The new program is targeting a levelized cost of energy of
