Çayırhan power station
Coal fired power station in Turkey
From Wikipedia, the free encyclopedia
Çayırhan power station is a 620 MW operational coal fired power station in Turkey in Ankara Province.[1] In 2019 land was expropriated for another lignite mine, to feed the a proposed extension, which was opposed as uneconomic and eventually had its licence revoked.[2][3]

History
In 2017 the government privatized the Çayırhan-B lignite coalfield on condition a coal-fired power plant is built, in the hope that it would be the first of a wave of similar deals for various lignite coalfields around the country.[4]
Ownership
The project was a joint venture between Kolin, Kalyon and Çelikler.[5] But in 2020 the licence expired and as of 2024 it belonged to EÜAŞ.[6] In 2025 it was sold to Akçadağ Holding for 20 billion lira.[7]
Finance
Economics
The winning consortium bid $60.4 per megawatt, but according to opponents of the extension expanding Turkey's solar power would save taxpayers money in the long term.[2]
Employment
The company said it would employ 500 people in the plant and 1,500 for coal mining.[5]
Coal supply
As Turkish lignite is heavy compared to its energy content coal must be sourced locally. According to one source Çayırhan is a longwall mine (therefore underground),[8] but Global Energy Monitor says it is opencast. Coalfields in Ankara province include Beypazarı-Çayırhan, Gölbaşı-Karagedik, Gölbaşı-Bahçeköy, Ayaş-Kayıbucak and Şereflikoçhisar.[4]
Environmental Impact
Despite the environmental impact assessment having been approved opponents of the extension claim the environment will be damaged.
Dust
As of 2020[update] the plant is operating with inadequate dust filters[9] and Turkey has no legal limit on ambient fine particules (PM2.5). Opponents claim that Nallıhan bird sanctuary, 6 km away, could be damaged.[2]
Sulfur Dioxide
As of 2020[update] the plant is operating with inadequate sulfur treatment,[10][9] and the area is a sulfur dioxide air pollution hotspot[11]
Nitrogen oxides
As of 2020[update] the plant is operating without sufficient NOx filtering.[9]
Greenhouse gases
After extension the power station would contribute an estimated 4 megatonnes (Mt) a year to Turkey's greenhouse gas emissions.[2] As Turkey has no carbon emission trading it would not be economically viable to capture and store the gas.[12]
Opposition
The Chamber of Mechanical Engineers has questioned why the existing plant was granted a 2020 operating license without meeting air pollution standards.[9] Opponents include Ankara 350.org and singer Tarkan.[2]
In 2022 the NGO Climate Change, Policy, and Research Association alleged that the power station did not comply with flue gas regulations, was burning coal from a mine which did not have a permit, and risked collapsing.[13]: 30 [14][15]
