Would redirecting wind toward a turbine cost less than adding another turbine?

Most countries that have a subsidy base it on the amount of electricity generated so it's in the interests of the wind farm developer to generate as much as possible. So it's not subsidies that stop developers installing larger turbines. Most new onshore turbines in the UK are 120-136m tall. Larger turbines are available (190m) but they aren't normally used onshore due to the impact on the landscape. They are however used offshore. If you use big turbines you need fewer of them and fewer foundations, cables etc so the capital cost per MW is lower. There are lots of reasons why developers would like to install bigger turbines.

It's not too late to be asking the OP what kW rating alternator is being planned. There are two threads progressing, unaware of each other and in parallel, I think. Comments about one do not apply to the other.
