Sustainable energy settles in the core of the economic activities since climate change issues have arisen. Decarbonization strategies of the electricity sector target to reach sustainable energy by liberalization movements. To adopt the sustainable energy portfolio similar to European Union ones’, Turkey took a step in decarbonization of the Turkish electricity sector by beginning with the public electricity sector. In this study, the decarbonization process of Turkish public electricity sector is projected under alternative scenarios by using the integrated model software tool, Long-range Energy Alternatives Planning (LEAP), from 2001 to 2050. Liberalization impacts on GHG emissions of Turkish public electricity sector and energy portfolio management after privatization are evaluated with the perspective of 3Es (Energy, Environment and Economy) in this study. The private electricity sector is exempt from the modeling. There are several methodologies applied at each stage of this study. Linear regression is implemented in the baseline of models such as forecasting the future resource price and electricity demand for various sectors. The model applied IPCC Tier-1 method placed in LEAP to calculate GHG emissions in the privatization period of the electricity generation sector. Levelized cost of electricity generation is the methodology used in social cost calculations. For analyzing the privatization impacts of GHG emissions, Business-As-Usual (BAU) Reference scenario, stating the current strategies in the public electricity sector, and No Privatization (NP) scenario, preserving the 2012 installed electricity generation capacity, are applied. Alternative, sustainable energy portfolios are offered in the Nuclear Energy (NE) and Renewable Energy (RE) scenarios. NE portfolio involves the 3rd and 4th nuclear power plants contrary to RE scenario, which targets the diversification in potential renewable energy sources. In conclusion, the government gets a benefit increase of 109.96 billion TL by implementing privatization in Turkish public electricity generation over the BAU scenario. In addition, cumulative GHG emission savings in BAU, NE and RE scenarios is 2.2 GtCO2eq. compared to NP scenario. The cost reduction per tCO2eq. are 47.76 TL in RE scenario and 45.57 TL in NE scenario. RE scenario distinguishes itself by its low projected costs and its diversified energy portfolio, which are complementary to 3E perspective of the sustainability.

Overcoming problems in Turkey's renewable energy policy: How can EU contribute?
Sirin, Selahattin Murat; Ege, Aylin (2012-09-01)
Fossil fuels cover most of the energy demand in the world, and this creates significant social, economic and environmental problems. Many countries have taken measures to increase the share of renewable energy sources (RES), especially in electricity generation, and the review of literature shows that the success of a country in RES diffusion depends on a comprehensive renewable energy policy which combines political commitment with stable and long-term support measures that stimulate technological innovati...
Capacity determination of pumped storage projects using market electricity prices
Çetinkaya, Semih; Tiğrek, Şahnaz; Department of Civil Engineering (2014)
Renewable and clean energy is gaining more importance after the nuclear disasters with increasing awareness of depletion of fossil fuels, concerns about the global warming and increasing energy demand. However, intermittency of renewable resources is the biggest challenge in the restructuring world energy market. Energy has to be stored against sudden changes in the production and consumption. In order to keep the continuity of the energy supply, pumped storage can be a remedy. Therefore, pumped storage pro...
Sustainable carbon constrained energy generation perspectives: Dataset
Çubukçu, Nilay; Tarı, İlker (2021-12-7)
There is a consensus that climate change, which is about to become a major disaster for humankind, is largely due to anthropogenic activities. Greenhouse gases (dominated by CO2) emissions play a dominant role there. Majority of the emissions results from energy consumption. Today, mitigating CO2 emissions consists one of the fundamental missions of the humankind. One such task is to reduce the global energy demand. Enhancing efficiency, recycling, promoting behavioral changes to reduce energy demandi...
Renewable energy planning in Turkey with a focus on hydropower
Gök, Emre; Kentel Erdoğan, Elçin; Department of Civil Engineering (2013)
As a country highly dependent on foreign fossil fuel sources, Turkey experiences many problems due to its increasing energy consumption in parallel with increasing population and rapid economic growth. Foreign fossil fuel dependency adversely affects sustainable development of the country by hindering its economic development. Because of this, renewable energy sources of the country should be evaluated and developed as soon as possible. Prioritization of the development of renewable energy sources to increa...
Evaluating maritime intelligent transportation systems: The case of using electric ferries and renewable energy in Türkiye
Pense, Caner; Akınoğlu, Bülent Gültekin; Atik, Oğuz; Department of Earth System Science (2022-10-26)
Climate Change and Global Warming are among the most critical global problems today. Their effects can be seen all over the world. The maritime sector contributes to global Climate Change and Global Warming with greenhouse gas emissions from coastal structures and ships. At the local level, it also negatively affects all life with environmental pollution, especially air and sea. Today, drive technologies are developing at a dizzying speed. In land transportation, electric vehicles are frequently seen. Elect...
