The 114 m high embankment dam is part of the Çoruh Development Plan, a 17-dam-cascade hydropower scheme designed to tap Çoruh River's hydropower potential. Aksu Dam will be located immediately upstream Arkun Dam (237 MW), and immediately downstream Güllübağ Dam (96 MW), both of which are already operational.[2]
It is expected to generate an average 382.5 GWh of electric power annually, which will contribute to 3.78% of Çoruh basin' hydropower generation and 0.54% of Turkey's.[3]
Its construction is supervised by Turkey's State Hydraulic Works.[4] Construction on access roads and diversion tunnels began in 2010.[5]
