Green Power Development Project – Construction of Dagachhu Hydropower Development in Bhutan
1) The Technology In Use === Hydroelectric Power Generation
The tiny nation of Bhutan, nestled high in the Himalayan Mountains, is poised to become an energy superpower. Its prime position between two populous and growing nations – China and India – means it has the opportunity to utilize vast natural resources of flowing water and cutting edge technology of hydroelectric dams. In a quest to attract clean, green and sustainable businesses, the nation continues to construct mega dams including:
Tala hydroelectric project (2007): located on the Wangchu River; gravity dam technology generates 3.821 GWh power solely for India and is delivered through transmission lines.
Chhukha hydroelectric project (1970s): located on the Wangchhu River; gravity dam technology generates 1.700 GWh.
Kurichhu hydroelectric project (2001): located on the Kuri Chhu River; gravity dam technology generates 0.379 GWh.
Basochhu hydroelectric project (Plant I & Plant II, 1997-2004): located near Wangdue Phodrang; dam technology generates 0.334 GWh.
Dagachhu hydroelectric project (Feb. 2015): located on Dagachhu River; gravity dam technology generates power for India. First cross-border CDM of the UNFCCC.
2) The Sustainability Problem ===
Population: China and India represent 20% and 17% of the world’s population, respectively. At the current growth rate, India is expected to surpass China in the next few decades.
Economic Growth: As more people in India rise out of poverty, per capita energy consumption increases.
Clean Energy: Coal, kerosene and wood burning are the common methods of energy generation in poor households and small villages where electricity is not available. Hydroelectric power is a renewable energy source which does not emit harmful GHGs.
Ecological Preservation: Harnessing hydro electric power while maintaining national commitment to environmental sustainability.
3) The Technology Stakeholders ===
Contractors (designers, workers, operators)
Suppliers of component parts
Government of Bhutan
Bhutan Utility subsidiary
India Utility distributor
4) Process for Technology Implementation ===
Identify needs of India consumers/population
Determine economic efficiency/profitability; cost of tech vs ROI
Educate/Inform Bhutan residents of impact on natural environment
Monitor energy output from plant and consumption in India
Foster collaboration between nations under multilateral organization
Share new technology and best practices
