Functions and viability of Turkish wholesale electricity trading and contracting company (tetas) in the short, mid and the long term

Ketencioğlu, Sinan
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.


Mathematical modeling and solution approaches for balancing Turkish electricity day ahead market
Yörükoğlu, Sinan; Avşar, Zeynep Müge; Kat, Bora; Department of Industrial Engineering (2015)
In the Turkish Electricity Market, electricity trade is carried out largely through Bilateral Agreements and the emerging short term imbalances are settled in the Balancing Power Market, particularly the Day Ahead Market. In the Day Ahead Market, the participants submit their bids for each hour of the next day in the form of price-quantity pairs and the Market Operator evaluates those bids using an optimization tool. After the evaluation of the bids, a Market Clearing Price at every hour of the next day and...

Şahin, Cem; Erkmen, İsmet; Department of Electrical and Electronics Engineering (2010)
Operation of the electricity markets is subject to a number of strict and specific constraints such as continuous load-generation balance, security of supply, and generation technology related limitations. Contributions have been made to two important problems of the Electricity Markets, in the context of this study. In this study, Price Based Unit Commitment problem in the literature, which is a tool for the GENCO for operations planning, is extended considering the interdependencies between the Natural Ga...
Analyzing the profit efficiency of the Turkish banking sector after the BRSA restructuring program in 2001: an empirical study using stochastic frontier approach between the years of 2002-2009
Hatunoğlu, Hande; Akbostancı Özkazanç, Elif; Department of Economics (2012)
This thesis analyzes the profit efficiency of the Turkish banking sector after the restructuring program by using Stochastic Frontier Approach. 28 banks are included in the analysis and the data belongs to the period 2002-2009. Profit efficiency scores of 28 banks are estimated by SFA. When the efficiency scores are analyzed according to the ownership status, profit efficiency scores of the state owned banks are found higher than other bank groups. Moreover, according to the asset size, large scale banks’ p...
Day ahead markets
Kütaruk, Kaan; Sevaioğlu, Osman; Department of Electrical and Electronics Engineering (2013)
Day Ahead Market is a mechanism in electricity markets for adjusting the supply-demand energy and capacity balance by providing bids one day before the clearing. Market operator needs to know the available energy and capacity for reaching minimal-cost supply-demand balance one day earlier than the market has been cleared. Minimizing cost of the electricity and capacity during 24 hours of a day requires accurate information concerning the available electricity and capacity. Day-ahead marketing activity is pe...
An Empirical Analysis of the Bank Lending Channel in Turkey
Ozsuca, Ekin Ayse; Akbostancı Özkazanç, Elif (2013-07-01)
The purpose of this paper is to empirically analyze the role of the banking sector in monetary policy transmission in Turkey covering the period 1988-2009. By exploiting dynamic panel data modeling approaches, the heterogeneity in banks' lending response to changes in policy interest rates is analyzed. Given the changes in the policy stance and developments in the financial system following the 2000-01 crisis, the analysis is further conducted for the two sub-periods, 1988-2001 and 2002-2009, to examine whe...
