Coal-Fired Power Stations in Turkey
Turkey's energy landscape relies on a diverse array of coal-fired power stations to maintain its electrical grid. These facilities range from massive utility-scale plants providing thousands of megawatts to small captive power plants—facilities designed to provide electricity specifically for an industrial site rather than the general public grid.
The infrastructure utilizes various types of fuel, primarily lignite (a soft, brown coal), but also incorporates imported bituminous coal, anthracite, and asphaltite to meet energy demands.

Key Facts
- Total Installed Capacity: Listed at 19,223 MW, though the energy ministry reports a higher figure of 21,931 MW.
- Primary Fuel Sources: Lignite is widely used, alongside imported bituminous coal and anthracite.
- Advanced Technology: The fleet includes subcritical, supercritical, and ultra-supercritical plants to improve efficiency.
- Major Operators: Key owners include EÜAŞ, Çelikler Holding, and Eren Holding.
- High-Output Hubs: Zonguldak and Çanakkale are significant regions for high-capacity generation.
Technological Classifications
The efficiency of a coal plant is largely determined by its boiler technology. Most older plants in Turkey are subcritical, meaning the water is heated to a temperature below its critical point. Newer installations, such as the Cenal plant, utilize ultra-supercritical technology, which operates at much higher pressures and temperatures to generate more electricity from the same amount of fuel, thereby reducing emissions per megawatt.
Fuel Types and Their Usage
The choice of fuel often depends on local availability. Lignite is common in regions like Muğla and Kütahya. In contrast, plants like Atlas and Cenal rely on imported bituminous coal, which generally has a higher energy density than lignite. Specialized fuels are also used, such as anthracite in the Çatalağzı plant and asphaltite in the Şırnak Silopi station.
Major Power Stations and Performance
The ZETES complex in Zonguldak represents some of the highest capacity in the country, with ZETES-3 alone providing 1,400 MW of installed capacity. Similarly, the Cenal plant in Çanakkale is a powerhouse of efficiency, utilizing ultra-supercritical technology with an installed capacity of 1,320 MW.
Performance is often measured by the capacity factor, which is the ratio of actual energy output over a period of time to the maximum possible output. For example, Bekirli-1 shows a high capacity factor of 89%, while others, like Afşin Elbistan A, operate at much lower rates (16%).

Industrial Cogeneration and Captive Plants
Beyond utility-scale power, Turkey employs many cogeneration plants. These facilities produce both electricity and useful heat (steam) for industrial processes. Examples include the Adapazarı Sugar Factory and various Alkim Alkali Chemicals sites. Some of these, such as the Göknur plant, are strictly captive, meaning they produce no output for the national grid.
Frequently Asked Questions
What is the difference between the listed capacity and the ministry's capacity?
The listed total is 19,223 MW, while the energy ministry reports 21,931 MW. This discrepancy may be due to the difference between net capacity (actual power delivered to the grid) and gross capacity (total power produced before internal plant use).
Which plants are considered the most technologically advanced?
The Cenal plant is among the most advanced due to its ultra-supercritical technology. Other high-efficiency plants include the ZETES-2, ZETES-3, Atlas, and Bekirli-2 stations, which utilize supercritical technology.
What is a captive power plant?
A captive power plant is a facility dedicated to supplying electricity to a specific industrial site. For instance, the Göknur food plant is a captive facility that provided no output to the general grid in 2019.
Which fuel is most commonly used in these stations?
Lignite is the most prevalent fuel used across the various stations, particularly in the subcritical plants located in provinces like Muğla, Kütahya, and Manisa.
Are any of these plants used for residential heating?
Yes, the Soma B power station uses its steam output for residential heating during the winter months.
