Wind farms are losing out on tens of millions of euro because of constraints in Ireland's transmission system and the problem is getting worse, a new study shows.

Wind farms lost €75.5m worth of revenue in 2019 - up from €49.7m in 2018 - because they were forced by grid operator EirGrid to either switch off completely or turn down their power output to the national grid at certain times, according to the report from the Irish Wind Energy Association (IWEA).

That meant wind farms therefore missed out on getting paid for the electricity they were not being allowed to produce because the national grid was unable to handle the load.
