The Polish government’s cold hostility to wind power has thawed in recent months, leading to hopes of a revival for the sector. Yet its actions and statements on the subject have been so confusing and contradictory that it has been hard for companies to plan a strategy for Eastern Europe’s largest economy.

Since coming to power in 2015, the nationalist-populist Law and Justice (PiS) party has ended a green certificate scheme, increased property taxes for wind farms and introduced the highly damaging 10H rule, which stipulates that no turbines can be erected within a distance equal to ten times its blade-tip height from a neighbouring property.
