Market Value of Electricity Generated Based on RES Utilization

Abstract

Proper calculation of required support for elektricity generation from RES needs information about market value of the electricity with respect to the electricity market rules and unique features of electricity from individual RES. The production of typical independent power units (IPU) is valuated by prices of electricity from competitive power plants. The economy of transition network and other high voltage networks has been considered as well because the IPU is usually not connected to the transition network. The production diagram of IPU and the production diagrams of entire electricity system in general do not fit. The differences of the diagrams are valued by short term (spot) market prices. Other factors being taken into account are deviations of the actual elektricity delivery from agreed diagrams due to heating regimes or we-ther conditions like wind speed variance. These deviations are appraised from data from electricity market operator. The article presents results of RES elektricity market valuation for the Czech Republic. Those market prices of IP electricity can be used for economic evaluation of investment to IPU or for regulation body for setting of green certificates or for other applications.
