We’re excited about this first project investment because it uses some of the latest wind turbine technology and control systems to provide one of the lowest-cost sources of renewable energy to the local grid. The turbines can continuously adjust the individual blade pitch angles to achieve optimal efficiency and use larger blades with 15 percent more swept area than earlier generations, allowing capture of even more wind energy for each turbine. The control systems for these wind farms are also advanced and dynamic, allowing for remote 24/7 monitoring and operation to ensure maximum turbine up-time and power production. A couple of us got a chance to climb 80 meters up one of the 113 turbines to see firsthand how the rotating blade motion goes through a gearbox to turn the generator that makes the electricity. The climb to the top also provided a great view of the entire wind farm (don’t worry — we all had harnesses and turned the turbine off!).

We look forward to finding more opportunities to invest in renewable energy projects that use the latest technologies to push the envelope for delivering low cost clean energy. We’ll let you know what we find.
