We visited the museum for wind turbines which is located up by the actual turbines. The taxi driver and the guide at the museum didn’t speak English so we got the gist of the explanations but not details. Still very interesting.
Wind turbines are usually good for about 20 years and then they have to be dismantled because the concrete foundation can become unstable. That was a surprise. The turbine itself could still be fine.
This demonstration project (11 Chinese made turbines) in Loja has been successful and they are planning to add additional turbines. Don’t remember the payoff period but I think it was something like 5-7 years. Pretty short time; very cost effective.
