Last week we were re-united with our old friend, the Westwind 10 turbine. The turbine was taken down in May to return to the factory. Along with turbines from Galson, Back and Barvas, our machine was re-engineered and brought upto the latest specification. The turbines were shipped back in September, but have been sat in DR MacLeods yard awaiting a gap in the installers schedule. The only difference that’s visible is the new tail design. We now have a horizontal wing on the tail. This will hopefully create lift making it easier for the turbine to furl and unfurl in strong winds.
On Thursday, Tarbert awoke to the sound of a helicopter circling and landing at Urgha. This was the guy who installed the turbine originally – coming back to see it go up again. He since went on to sell his company and get a helicopter to visit turbine sites from his Shetland home.
Anyway, the turbine was erected successfully at lunchtime, in a good stiff breeze. We’ve had some good wind since then and are generating once more. We can also now use the Logic Energy remote monitoring facility. This was installed in the summer, but has obviously not been much use without the turbine. Now, without leaving the warm office, we can see how windy it is and how much we are generating. After the first few days, it appears as though the wind direction is not reading true. That’ll have to wait till the tower comes down again. The figures update every 10 minutes and will show 7 days of readings. The monitoring is also highlighting a maximum of 8kW in the windiest of conditions. The turbine is designed as a 10kW machine, so despite the return to the factory, we still appear to have a problem.
