Assessing the efficiency of solar and wind power plants at three levels

Abstract

The article substantiates why indicators designed for conventional generation are insufficient for assessing the efficiency of solar and wind power plants. A system of indicators assessing efficiency at the technological, enterprise and power system levels is proposed, together with rules for converting technological losses into the enterprise's financial result and the enterprise's generation into system integration costs. The method is tested on open data for the Nur Navoiy Solar photovoltaic plant.
