Vietnam Approves 47MW Floating Solar Project on Dong Nai 2 Hydroelectric Reservoir
The People's Committee of Lam Dong Province has officially approved the investment proposal for a floating solar power project on the Dong Nai 2 Hydroelectric Reservoir, marking a significant advancement in Vietnam's renewable energy development, particularly in the Central Highlands region.
The decision simultaneously authorizes Trungnam Power Joint Stock Company - a subsidiary of Trungnam Group - as the investor to implement the Floating Solar Power Plant project on Dong Nai 2 Hydroelectric Reservoir. This innovative approach represents a pioneering initiative in utilizing reservoir surfaces for floating solar installations, offering multiple environmental and operational benefits.
Project Overview
The Floating Solar Power Plant on Dong Nai 2 Hydroelectric Reservoir is one of the first initiatives to utilize reservoir surfaces for floating solar panel installations. This model not only conserves land resources but also reduces water surface evaporation while potentially complementing hydroelectric operations to optimize electricity generation.
The implementation of this project aligns with Vietnam's renewable energy development strategy, aiming to achieve a 35-40% renewable energy share in total electricity generation by 2030 and increasing to 60-65% by 2050, as committed at the COP26 conference.
Investor Profile
Trungnam Power Joint Stock Company is a subsidiary of Trungnam Group - one of Vietnam's leading renewable energy developers. Trungnam has extensive experience in implementing large-scale energy projects, particularly solar and wind power developments across the country.
To date, Trungnam has successfully implemented numerous renewable energy projects nationwide with a total installed capacity of thousands of MW. Notably, the Trungnam 1 Solar Power Project in Ninh Thuan Province with a capacity of 450 MW was once the largest solar power project in Southeast Asia upon completion.
Project Details
The floating solar power project on Dong Nai 2 Hydroelectric Reservoir is planned with a total installed capacity of 47 MW. The project will utilize floating solar panel technology designed to withstand the harsh weather conditions of the Central Highlands climate.
According to the planning, the project will be divided into several floating solar clusters, securely anchored on the reservoir surface to ensure safety during adverse weather conditions. The system will connect to the national grid through the existing substation and transmission lines of the Dong Nai 2 Hydroelectric Power Plant.
The project is scheduled to commence in Q4/2023 and be completed by Q4/2024, with commercial operation expected to begin in early 2025. Once operational, the floating solar power plant will generate approximately 80 million kWh of electricity annually, sufficient to power around 32,000 households.
Significance and Benefits
The floating solar power project on Dong Nai 2 Hydroelectric Reservoir offers numerous significant benefits:
- Enhanced renewable energy: Contributes to Vietnam's commitment to reduce carbon emissions as pledged at COP26.
- Optimized land use: Utilizes reservoir surfaces without competing with agricultural or residential land.
- Reduced water evaporation: The floating solar panel system helps reduce water surface evaporation, conserving water resources in the reservoir.
- Improved hydroelectric efficiency: Reduced water evaporation helps maintain reservoir water levels, increasing the efficiency of hydroelectric power generation.
- Local economic development: Creates jobs and promotes socio-economic development in the local area.
Challenges and Prospects
Despite its significant potential, the floating solar power project also faces several challenges:
- High investment costs: Construction costs for floating solar are higher than traditional ground-mounted solar installations.
- Complex technical requirements: Requires specialized technical solutions to ensure the floating system remains stable under harsh weather conditions.
- Environmental impact assessment: Requires thorough research on the impact on the underwater ecosystem.
However, with support from local authorities and the investor's experience, the project is expected to succeed and open new avenues for renewable energy development in Vietnam.
Comparison of Solar Power Types
The following table compares common types of solar power in Vietnam:
| Type | Ground-mounted Solar | Floating Solar | Rooftop Solar |
|---|---|---|---|
| Typical Capacity | 50-500 MW | 10-100 MW | 1-5 kW/household |
| Characteristics | Requires large land areas | Utilizes water surfaces | Installed on rooftops |
| Investment Cost | Low to moderate | High | Low |
| Implementation Time | 6-12 months | 9-15 months | 1-3 months |
| Environmental Benefits | Reduces CO2 emissions | Reduces CO2 emissions and evaporation | Reduces CO2 emissions |
Conclusion
The approval of the floating solar power project on Dong Nai 2 Hydroelectric Reservoir represents a significant step in Vietnam's energy transition journey. With the intelligent combination of hydroelectric and solar power, the project not only contributes to energy security but also promotes sustainable development, reduces greenhouse gas emissions, and protects the environment.
This project also opens new directions for renewable energy development in Vietnam, particularly in regions with numerous reservoirs like the Central Highlands. The success of this project will serve as a foundation for expanding the floating solar model at other hydroelectric power plants nationwide.
