About the Ilisu Dam

The Ilisu dam site will be situated on the Tigris river, just 65km upstream from the Syrian and Iraqi border. It is currently the largest planned hydropower project in Turkey.

The Ilisu is planned as a rockfill dam, 1820m long and 135m high. Its reservoir would cover a surface area of 313 square kilometres and contain up to 10.4 billion cubic metres of water. The Ilisu power station will have a capacity of 1,200 MW, and is expected to produce 3,800 GWh of power per year.

The Ilisu dam is expected to cost $1.52 billion – though that does not include financing costs, which could boost the price up to $2 billion or more. Building of the dam is due to start in 2000 and finish in 7 – 8 years.
