Wind Farms get paid for NOT generating electricity

WOW am I mad. I found out today that Wind Farms get paid for NOT generating electricity!

Its  bad enough that they are so subsidised to make it worth while in the first place, I've said this before but to actually be told NOT to generate electricity and then get Compensation is MAD!

Its a bit technical but the National Grid pays all Generators compensation if they don't need the electricity they are generating - effectivly throwing it away and compensating them. SO if its too windy and there is loads of Wind Energy and we don't need it they tell them to stop and compensate them. 

CRAZY.

We should use all the Wind Energy and shut down the Coal/Gas/Nuclear/Oil etc.?
