Bhutan has an estimated hydropower potential of 30,000 MW and 12 TWh mean annual energy generation. So far 23,760 MW has been identified and assessed to be technically feasible. Only 1.488 MW,  i.e., 5% of the feasible potential is harnessed so far. Royal Govt.

Bhutan's ability to harness the hydropower resources has been made possible because of the close and friendly ties with its neighbour India. India has been providing both technical and financial assistance to develop the numerous hydropower projects in Bhutan. India has huge power shortage where as Bhutan has large hydropower potential. The relationship developed in the hydropower sector has been a win-win situation for both the countries.

Generating units for hydro power plants are tailor made to meet the specific requirements of site conditions. In the large units of the size of Tala Hydro Power Plant, major assemblies are required to be done at site due to transportation limitations.

The 720MW Mangdechhu Project is located on Mangdechhu River in Trongsa Dzongkhag (District) of Central Bhutan. The dynamic analysis for the Mangdechhu Concrete Das is still to be carried out and the site specific seismic design parameters are under vetting by the National Committee for Seismic Design Parameters (NCSDP), India
