Nákup energie prostřednictvím e-aukcí

Abstract

This paper deals with the purchase of energy through e-auctions. The researched issue was to determine the influence of the stock market price on the final price of the auction, the influence of the timing at auction and what is the margin of suppliers. The problem was studied using regression analysis of data obtained from the companies dealing with auctions and supplemented by data from PXE. The analysis of the data showed that there is a connection between the quoted market price auction and winning price exists. Furthermore, the timing of the auction is important especially with regard to developments in prices on the stock exchange and, finally, that the margins of suppliers for contracts for 12 and 24 months is not much different and is influenced mainly by the number of auctioned MWh. The resulting recommendations for small and medium-sized companies is therefore purchase of electricity through public auctions and other companies to fix the price for 12 or 24 months, depending on the expected development of electricity prices on the stock exchange.
