Funding
The owner was the Norwegian,
Statkraft, at a cost of US $678 million. The Contractor was Yϋksel-iLci Joint Venture. Veidekke Industri AS was the subcontractor for Cetin dam. In September 2017,
Limak invested $400 million to purchase the rights, in order to complete the whole project by 2020–21.
Timeline
Construction on the main dam began in December 2011 and the power plant was first expected to be complete in 2015, with a planned capacity of 401 MW.
The project experienced delays due to

attacks on the construction site and equipment. In February 2016, Statkraft suspended construction.
Works resumed in July 2017.
Construction was 84% complete as of September 2019 ; at that time, as many as 15,000 m
3 of concrete are poured onto the structure every day.
The dam started impounding water in January 2020.
The first two units of the power station started generating electricity in April 2020, whereas the two remaining ones are expected to be commissioned by May 2020.
