Project overview

This project is located in the northern part of Sumatra Island in Indonesia and involves the construction of a 5-meter-high concrete weir, which is connected to a 715 m long tunnel measuring 3 x 4 m. Water from the tunnel is fed through a low-pressure GRP pipe and high-pressure steel pipe to a newly constructed powerhouse. Two vertical Pelton turbines are installed inside the powerhouse, harnessing a 285-meter head, and rated power is 13.8 MW.

As part of the project have been designed a new access road to the dam, tunnel end, and powerhouse. The access road to the powerhouse is situated on a steep slope and therefore had to be designed as a system of several serpentines.
