NREL Collaborative Improves the Reliability of Wind Turbine Gearboxes (Fact Sheet)

    Research output: NRELFact Sheet


    Gearbox failures have a significant impact on the cost of wind farm operations. To help minimize gearbox failures, in 2007 the National Renewable Energy Laboratory (NREL) initiated the Gearbox Reliability Collaborative (GRC), which consists of manufacturers, owners, researchers, and consultants. Based on all the lessons learned from the past five years, the GRC has now produced a new and improveddesign, which is projected to yield an operating lifetime of 12 years, more than triple that of the previous redesigned gearbox. The GRC findings will result in increased gearbox reliability and an overall reduction in the cost of wind energy.
