• Bridge

    From familiar bridges used in daily life through to long span bridges

    Since its foundation, Komaihaltec Inc. has continuously been building numerous high quality products in the steel bridge domain, including road bridges and railway bridges. In addition to steel bridges, we have branched out in recent years to build bridge structures made from composite materials comprising steel and concrete, and we are actively involved in preventative safety as well as maintenance and preservation work in order to extend the life of our bridges.
    In the future, we will further contribute to the establishment of social infrastructure by maximizing the technological capabilities that we have built up over many decades, and by working diligently in the research and development of a wide range of areas.

Construction of the first wind farm
for the Kingdom of Bhutan

Overview of wind turbine construction works in the Kingdom of Bhutan

Location: Wangdue Phodrang District, Bhutan
Owner: Bhutan Power Corporation Limited ('BPC')
Max. power output:600kW (2 x KWT300 turbines)
Construction perio

Komaihaltec Inc. has been commissioned by Bhutan Power Corporation Limited ('BPC') to construct the country's first wind farm. This construction work will involve the installation of two of Komaihaltec's 300kW wind turbines in Wangdue Phodrang District in western Bhutan.
Bhutan boasts abundant water resources, and almost all of the country's power demand is dependent on hydroelectric power generation. However, the Bhutanese government is concerned that the country's water resources may be insufficient in the long term, and has therefore decided to diversify its power generation by promoting renewable sources of energy.
This construction will be implemented as a pilot project for wind-generated power, with financial support from the Asian Development Bank. The Bhutanese government aims to implement wind-generated power on the scale of 5MW by the year 2020.
The Wangdue Phodrang District is located approximately 2 to 3 hours by car from the nation's capital, Thimphu, and features the Puna Tsang Chu River, which is one of several rivers traversing Bhutan from north to south. The region is known for its strong winds, and is characterized by a powerful southerly wind that blows up-river.
