Residential energy efficiency: Turkish case

Kartal, Aysun
This study aims to analyze residential electricity demand of Turkey between 2008 and 2015, provide relative efficiency scores of provinces in electricity use and reveal the determinants of (in)efficiency through stochastic frontier approach. Empirical results indicate that having higher income, inhabiting in densely populated provinces and living at detached houses result in increasing electricity consumption at the residential sector. On the other hand, as household size increases, electricity consumption per capita decreases. The findings also point out that Turkish households do not use electricity for the purpose of heating and cooling in general. Nonetheless, prosperous provinces use electricity for cooling at high temperatures. Based on the estimated efficiency scores, 8-year mean energy efficiency of Turkey is found to be approximately 0.83. This suggests that on average Turkey could have used 17% less electricity to produce the same amount of energy services between 2008 and 2015. In other words, Turkish households have an average electricity saving potential of 17% in the study period. The results of the inefficiency effects equation suggest that being well-educated of women and being married have a positive impact on improving residential efficiency. On the other hand, provinces located in the coastal area and those with higher loss-illegal electricity use rates are more inefficient in electricity use. Furthermore, the findings of the study imply that inefficient use of electricity at the residential sector has not declined over time. This can be evaluated such that the efficiency policies implemented by the authorities after 2007 did not have a significant impact on improving efficiency in residential electricity use. Since our study is the first one that analyzes electricity consumption and efficiency at the provincial level based on frontier analysis, it can shed light on the consecutive studies of regional development and energy efficiency.


Hydro-Optimization-Based Medium-Term Price Forecasting Considering Demand and Supply Uncertainty
İLSEVEN, Engin; Göl, Murat (2018-07-01)
This paper proposes an electricity market model of Turkish electricity market for monthly and yearly electricity price forecasting in medium-term by means of supply and demand dynamics formed via a theoretical approach. The electricity market model created within this scope consists of three main components related to electricity demand, supply, and price segments along with hydro optimization submodel, which takes into account the nonlinear relation between supply and price. Electricity price is determined...
Solar energy R&D, technology and economics in Turkey
Taşdemiroğlu, E (Elsevier BV, 1990-1)
The solar energy potential of Turkey is assessed. Solar energy R&D programs and technology and the present market for flat-plate solar collectors are briefly reviewed. The potential share of solar energy in the total energy budget is estimated.
Solar domestic water heating in Turkey
Akınoğlu, Bülent Gültekin; Ecevit, A (1999-05-01)
In this report we discuss the present situation of solar water heating for domestic supplies in Turkey and give the results of a computer analysis for nine distinct regions. The analyses are carried out for four typical days of the four seasons and also on a monthly base. The results show that detailed initial work must be carried out before installing the system to determine the optimized collector area. Such analysis can provide efficient using of the Sun's energy as well as economical benefits in the ini...
Extensions for Benders cuts and new valid inequalities for solving the European day-ahead electricity market clearing problem efficiently
Ceyhan, Gökhan; Köksalan, Mustafa Murat; Lokman, Banu (2022-07-16)
© 2021 Elsevier B.V.We study the day-ahead electricity market clearing problem under the prevailing market design in the European electricity markets. We revisit the Benders decomposition algorithm that has been used to solve this problem. We develop new valid inequalities that substantially improve the performance of the algorithm. We generate instances that mimic the characteristics of past bids of the Turkish day-ahead electricity market and conduct experiments. We use two leading mixed-integer programmi...
Solar repowering of Soma-A thermal power plant
YILMAZOĞLU, MUSTAFA ZEKİ; DURMAZ, Ali; Baker, Derek Keıth (2012-12-01)
In this study, solar repowering of the Soma-A thermal power plant in Turkey is investigated using simulations. The Soma A thermal power plant began operation in 1957 and has served until 2010. In the current situation the installed capacity of the power plant is 44 MWel with two units. In the simulations full load and part load operations are considered and compared for three different cases: (1) current case; (2) solar steam generation; and, (3) solar feed water heating. Economic analyses are performed by ...
