Project Development Objective
To supply least-cost electric power in a safe and environmentally and socially sustainable way.
- Part of a national plan to satisfy increasing demands of energy in a country where electricity demand has been growing at 15% for the past several years.
- Facility to produce an additional 1,019 GWh/year out of 10,000 GWh/year additional estimated to be required (conservative scenario post 2008 crisis).
- Climate Change: CO2 emissions of about 1 million tonnes per year avoided net, taking into account the additional but low emissions from reservoir)
- Energy Mix and Energy Security: Contributes to the development of Vietnam’s low-cost medium sized hydro, part of the least cost expansion plan, which includes about 4,800MW of hydro, which is preferred to thermal alternatives.
- International Standards in Dam Safety, Social & Environmental aspects adopted
- Multipurpose, run of river, hydropower project (power generation, irrigation and flood control)
- First project to dam Ma River / contemplated within Vietnamese Energy and River Basins Master Plan
- World Bank’s first hydropower project in Vietnam
- 8 out of 10 World Bank safeguards triggered.
- Main features to include:
- a 84.50 meter-high dam on the Ma River.
- a 260 MW installed capacity for power generation with a 13.13 square-kilometer reservoir.
- a powerhouse containing four (4)65 MW Francis turbines each designed for a maximum water head of about 72 m
- a 20.4 kilometer access road connecting the road system to the project site.
- a 65 kilometer-long, 220-kV transmission line connecting to the Vietnamese national grid. Social, environmental and community relations programs to mitigate project anticipated and unanticipated impacts to a population of about 10,600 persons.
- Electricity generation for domestic consumption (residential and industrial)
- First loan to Vietnam under IBRD lending conditions (27 yrs maturity & 6 yrs grace period).
- US$330 million to be financed by the World Bank out of total cost of US$ 411.57.
- Initial road access and bridges work done under retroactive financing conditions.
Social and Environmental impacts and mitigation measures
- 10,600 persons to be directly or indirectly impacted of which 7,012 are impacted by the main project area (dam and ancillary works construction).
- 98% of affected population belonging to ethnic groups: Thai. Hmong, Kho Mu and Muong.
- Community Livelihood restoration and Resettlement programs including the construction of infrastructure (roads, power supply, water for household and irrigation, schools and housing).
- Public Health Action Plan targeting resettlers to ensure any adverse impacts are detected and mitigated.
- Environmental Management activities to support biodiversity, protected areas and physical cultural resources.
- Multilingual Consultations conducted.
- Continued consultation at Livelihood, Resettlement and Environmental programs implementation.

Results evaluation - Project’s Key development indicators
- The amount of electrical energy and peaking capacity provided by the TSHPP.
- The economic and financial cost of electricity from TSHPP.
- Livelihoods of those affected by project to be at least maintained at pre-project levels.
- Evidence of satisfactory compliance with the Environment Management Plan (EMP).
Intermediate Results and evaluation indicators
- Intermediate Results for the Dam and Ancillary Construction Component: (providing the basis on which least cost electric power is generated)
- Progress in procurement of three main contracts: main works, electro mechanical equipment and owner’s engineer
- Construction of dam and appurtenant structures
- Construction of access road and bridges
- Construction of power supply line
- Intermediate Result for the Transmission Line Construction Component: (the means by which power generated is moved to consumers).
- Construction of 220kV power evacuation transmission line
- Intermediate Result for the Social and Environment Impact Mitigation Component: (ensuring socially responsible and environmentally sustainable construction and operation of the Trung Son Hydropower Plant)
- Resettlement compensation: households fully compensate.
- Livelihoods development: capacity enhanced in all villages
- Effective awareness of all ethnic groups of health risks
- Public Health Action Plan being implemented in project communes
- Environment management plan completion and successful in reducing impacts as expecte
- Corrective actions or new adaptive management programs implemented if existing mitigation measures do not reduce or eliminate impacts.
- Intermediate Result for Capacity Development and Scale-up Component: (scaling up the impact of the environmental sustainability and socially responsible construction of the plant by leveraging the knowledge gained to other projects in Vietnam)
- Pipeline projects incorporating international technical, social and environment standards
