ECONOMIC EFFICIENCY OF COMBINED-CYCLE POWER PLANTS AT BIOFUELS

Abstract

The prospects of use of biofuels for power plants as one of the priority way for energy development of Ukraine and world energy are considered. The ways to improve the economic efficiency of power generation systems based at alternative fuels for rising energy security of countries, improving the environment and preservation of traditional energy sources are estimated. A method of determination of economic efficiency the combined-cycle power plant by comparing its payback period which depends of electric power and the type of fuel is worked out. The analysis of the economic feasibility of using combined-cycle power plants at biofuel and feasibility study of use of biogas power plants that provide thermal energy for heating and hot water supply both the production of clean bio-fertilizers are presented. Justification of the prospects for using combined-cycle power plants at biofuels and the ways of reducing the payback period at principles of energy-saving technologies are given.
