Corporate social responsibility
The operators of these wind farms are diverse. Some are operated by companies that specialize in wind power like Aspiravi or Electrawinds. Others by traditional electricity producers Electrabel and Luminus. Several are operated by cooperatives like Ecopower or Aspiravi Samen. Finally a few are operated by organisations with a different core business like retail network Colruyt or pharmaceutical company Pfizer as part of a Corporate social responsibility strategy. Colruyt's turbines produce an estimated 13.75 GWh annually.
