The Trung Sơn Dam (Dự Án Nhà máy Thủy điện Trung Sơn) is a hydroelectric power station on the Ma River in northwestern Vietnam. Located in the Trung Sơn commune, Quan Hóa District, Thanh Hóa Province, it is approximately southwest of Hòa Bình city, and northwest of Thanh Hóa city. The dam created a reservoir which covers a large area of the Mường Lát and Quan Hóa Districts in the Thanh Hoa province as well as part of the Mộc Châu District in Sơn La Province. It is approximately from the Vietnam–Laos border. The 260 MW associated power plant became fully operational in September 2017.[1]
The Trung Sơn hydropower project is owned by Trung Sơn Hydropower Company Limited (TSHPCo), the entity established by Vietnam Electricity (EVN) in Decision No. 106/QD-ENV dated March 17, 2011. TSHPCo is responsible for the management, construction and operation of the Trung Sơn hydropower project.
The project provides both power generation and flood control. The powerhouse is designed to contain four generating units with a total capacity of 260 MW and an annual output of 1,018.61 GWh,, a significant addition to the national grid. The flood control storage of will help prevent floods downstream.
The project cost a total of VND 7,775,146 million (equivalent to US $410.68 million).[2] This includes US $330 million from a World Bank loan, which was signed by the Socialist Republic of Vietnam and the World Bank on June 28, 2011. Additionally, the project was given slightly over US $80 million from the counterpart fund of (EVN).
The project has created social, environmental and community relation programs to mitigate anticipated and unanticipated issues with populations either directly or indirectly impacted, the Resettlement, Livelihoods and Ethnic Minorities Development Program (RLDP). These populations consist of approximately 10,600 people (2,327 households), of which 7,012 (1,516 households) will be directly impacted in the main project area, resulting in a total of 533 households having to be resettled. The RLDP includes a Resettlement Plan (RP), a Community Livelihoods Improvement Plan (CLIP) and an Ethnic Minorities Development Plan (EMDP).
In addition, management has prepared a Supplementary Environmental and Social Impact Assessment (SESIA) with Environmental Management Plan (EMP) for the project. This plan includes principles, approaches, procedures and methods to be used to control and minimize environmental impacts of all project-related construction and operation activities. Compared with fossil-fuel based energy plants of the same size, the dam produces far less greenhouse gas emissions (GHGs). TSHPCo maintains a website at www.trungsonhp.vn where public information is routinely updated.
The project is composed of four components:
Category | Amount of the Loan allocated (US$) | Percentage of Expenditure to be financed (including tax) | |
---|---|---|---|
