NREL technical report: Gearbox Reliability Collaborative phase 3 gearbox 2 test plan

Gearboxes in wind turbines have not been achieving their expected design life; however, they commonly meet and exceed the design criteria specified in current standards in the gear, bearing, and wind turbine industry as well as third-party certification criteria. The failures are widespread across manufacturers and turbine sizes, and the majority of these failures are

NREL drives research on hydrogen fuel cells

Editor’s note: This article comes from NREL and is written by Bill Scanlon.  It is significant because the hydrogen to fuel the cells will have to be electrolyzed and that is a good job for wind generated power. Further developments would let such car owners drive on wind power, another good thing.  Hydrogen fuel cell

EPRI unveils study on the integrated electric grid

The Electric Power Research Institute has launched a study on the transformation of the electric power grid.  The rapid rise of Distributed Energy Resources (DER) — such as rooftop solar panels and high-tech microgrids — could change the structure of the electric grid.  Yet even as these technologies rise rapidly, few organizations have looked at

The map show an expanded area of potential wind energy available by increasing hub height from 96 to 140m. Projects supported by the funding will engineer design concepts for fabricating and installing turbine and tower systems with a minimum hub height of 120m.

Energy Department announces funding to access higher quality wind resources and lower costs

The Energy Department has announced $2 million to help efficiently harness wind energy using taller towers. These projects will help strengthen U.S. wind turbine component manufacturing, reduce the cost of clean and renewable wind energy, and expand the geographic range of cost-effective wind power in the United States. This effort supports the Energy Department’s broader Clean

NREL Study: Active power control of wind turbines can improve power-grid reliability

The National Renewable Energy Laboratory (NREL), along with partners from the Electric Power Research Institute and the University of Colorado have completed a comprehensive study to understand how wind power technology can assist the power grid by controlling the active power output being placed onto the system. The rest of the power system’s resources have

NREL releases Renewable Energy Data Book detailing industry growth in 2012

The National Renewable Energy Laboratory (NREL) has released the 2012 Renewable Energy Data Book on behalf of the Energy Department’s Office of Energy Efficiency and Renewable Energy. The annual report is an important assessment of U.S. energy statistics for 2012, including renewable electricity, worldwide renewable energy development, clean energy investments, and data on specific technologies.

The new facility at NREL will test wind turbine drivetrains with capacity ratings up to 5 MW.

NREL, DOE dedicate new 5 MW wind turbine dynamometer and test facility

The Energy Department’s National Renewable Energy Laboratory (NREL) will dedicate its new Dynamometer Test Facility at NREL’s National Wind Technology Center (NWTC) on November 19. The facility offers industry engineers the unique opportunity to conduct a wide range of tests on the mechanical and electrical power producing systems of a wind turbine. As one of
