The Zonguldak Eren Termik Santrali (ZETES) power stations in Zonguldak are 3 coal-fired power stations in Turkey totaling 2790 MW owned by Eren Holding via Eren Enerji.

Built between 2010 and 2016, ZETES-1 is 160 MW, ZETES-2 is 1230 MW and ZETES-3 is 1400 MW.^[1] Together they are the largest installed capacity coal-fired power stations in Turkey and are estimated by Climate Trace to emit over 15 million tons (Mt) CO₂ per year, over 2% of Turkey's greenhouse gas emissions.^[2] Located within about a kilometer of each other and the Black Sea the plants burn bituminous coal imported via the nearby Eren Port. ZETES-3 was financed by IşBank and Garanti Bank.^[3]

The plants received 13 million lira capacity payments in 2018,^[4] and 10 million lira in 2019.^[5] In 2022 the plants generated over 16 TWh of electricity.^[6] The emission factor was estimated at about 870g CO2eq per KWh in 2020.^[7]

Their licences end in 2053. For ZETES-1 it is estimated that closing the plant by 2030, instead of when its licence ends, would prevent over 1000 premature deaths. For ZETES-2 it is estimated that closing the plant by 2030, instead of when its licence ends, would prevent over 4000 premature deaths. For ZETES-3 it is estimated that closing the plant by 2030, instead of when its licence ends, would prevent over 5000 premature deaths.^[8]
