Initially, a Norwegian firm decided to develop Tamakoshi hydropower project, with an installed capacity of 650 mw, but discontinued due to political tension between Nepal and India. However, in 2019, two Chinese and one Nepali firm have decided to jointly develop the Tamakoshi 3 hydropower project of 200 mw with worth investment of USD 500 million on Tamakoshi river in Janakpur, Nepal. The companies included China’s YEIG International, Shanghai Investigation Design and Research Institute and Nepal’s TBI Holdings. The Energy Ministry of Nepal was uninformed of this joint venture. The commencement of joint venture was planned to begin in 2020 and to be completed within 3.5 years but the construction is likely to start in 2024 and it will be operational in 2027. The reason of delay in commencement is yet unknown.
