Prospective and existing wind-energy projects appear set to face Civil Aviation Authority restrictions over their distances from VOR navigation systems.

It is believed that a ministerial decision, expected to soon be published in the government gazette, will limit the number of wind park projects to five per 15-km radius of each VOR base.

A total of 47 VOR navigation systems operate around various parts of Greece. The measure threatens to halt the licensing procedures for prospective wind-park projects. It remains unclear how many projects, including existing facilities, could be affected.

According to sources, the Civil Aviation Authority has already reacted against at least one wind energy project, a development that has raised fears of multiple blockages.

ELETAEN, the Greek Wind Energy Association, is preparing to react as the sector’s growth prospects are under threat.
