ÇAKIT POWER PLANT

The Çakıt hydropower plant is a run-of-river plant utilising the Çakıt River close to Karaisalı in Adana province in Turkey. It has an installed capacity of 20 MW and will have an average annual production of 95 GWh. This amounts to the electricity consumption of about 32 000 Turkish households.
