Özet:

This thesis analyses the necessity for the establishment, main functions and the viability of the Turkish Wholesale Electricity Trading and Contracting Company, TETAŞ in the short, mean and the long term. In order to understand the necessity for the establishment of TETAŞ, Turkish Energy Policies such as the state-led energy policies and the competition based market orientation are put under scrutiny. The thesis also discusses whether Turkish Government has carried out a comprehensive, deterministic and effective “Liberalization Policy” in the electricity sector by looking at the present situation and the principles outlined in Laws No: 4628, 5654 and 5686 and the Strategy Paper. The dissertation then examines the life span of TETAŞ by looking at the impacts of the strategy paper, liberalization procedure of the overall electricity market and newly enacted laws such as Law No: 5654 and 5686 in the short, mean and the long term. In addition, TETAŞ is examined whether it is a “monopoly” or not in Turkish Electricity wholesale market by calculating the supply concentration of TETAŞ using the Herfindahl Hirschman Index. Despite the studies on the establishment of the liberal market such as the envisagement of Law No: 4628 and the strategy paper, this thesis study envisages that it is still not possible to talk about a liberal electricity market. In addition, it is also concluded that the statements outlined in Laws No: 5654 and 5686 hinder the overall liberalization efforts since these laws are postponing the liberalization of electricity sector and making the life span of TETAŞ longer. As a result, liberalization efforts on the electricity market are unsuccessful in the mean term and TETAŞ seems to hold its dominance position in the wholesale market as a state-owned wholesale trading company in the long run.
