The increase in height and expansion of the existing dam for the Blue Lake reservoir by 25 m increases the efficiency of the hydroelectric power station by 27 % to 15 MW. The new arch dam now has a 70 m overall height with the dam crest more than 80 m long. In addition, new intake structures and penstocks for power plant operations were realized.

The formwork provided by PERI for the dam, especially for the cantilevered spillway, was critical to the success of this remote project. Customer support and logistics were top notch in delivering formwork via a 5 day trip by barge.
