Wind Turbines

Another renewable energy source concerns smaller wind turbines, i.e. with a capacity of up to 50kW, which are substantially subsidised at quite high selling prices by virtue of Law 3851/2010. These are no- or low nuisance installations (depending on the power capacity installed) at small, electricity-producing wind farms, which have no impact on their surrounding environment, since they require no special infrastructure interventions – as opposed to major wind generating plants – nor produce high noise emissions. Another advantage of small wind turbines is that, depending on their technology, they can operate with very low wind velocities, and, therefore, they need not be installed on remote sites of very high wind potential.
 
Modern wind turbines may have a horizontal or vertical axis. Currently, the horizontal axis type prevails in the market. Indicatively, a small 50 kW wind turbine, installed on a site with a mean wind velocity of 7m/s produces 150,000 kWh a year. This, combined with favourable pricing, makes small wind turbines an attractive investment.
