ENERGY EFFICIENCY OF WIND POWER PLANTS, CASE OF LITHUANIA

Abstract

The use of energy from wind power plants in a building must be subdivided into renewable and non-renewable energy. Wind power efficiency increases with less auxiliary, i.e. non-renewable energy to produce the same share of electricity. The conditions and circumstances of wind power use are assessed in the calculation of the values of the primary renewable and non-renewable energy factor. The European Standard EN 15603 covers the main principles for calculating primary factors for renewable and non-renewable energy. However, the specific factor values for electricity produced in different wind power plants are determined in accordance with national conditions and requirements. In this article, in accordance with the main regulations of EN 15603, the main factor of nonrenewable energy of different power-generating wind power plants was calculated using electricity generation and Lithuanian wind power data and Lithuanian climate conditions in 2007. -2014. Research has shown, that the values of non-renewable primary energy factor for wind turbines operated in Lithuania and calculated according to EN 15603 methodology is 97 % lower than the numeric indicator from the same standard used for calculations.
