Several projects of land wind farms with a full power of nearly 1 GW have a chance to implement again. This is the consequence of a decision made at the Ministry of Defence. Changes in 6 temporary airspace zones will make wind farms. This decision is followed by months of analyses and arrangements conducted jointly by the military and investors associated with PWEA. The conclusion is simple: defence and wind energy can talk to 1 another, and that is the reason for this discussion.
