Vietnam's Grid-Stressed Energy Aspirations Challenged by VinEnergo's 43MW Solar Expansion
Vingroup's Solar-Powered Project Aims to Pioneer Clean Energy in Vietnam
Vietnam is set to significantly increase its solar capacity by 2030, with ambitious plans to reach between 46-73GW, a notable increase from earlier projections. One of the key contributors to this renewable energy drive is the VinEnergo Energy Joint Stock Company, which has announced a solar-plus-storage project in Ha Tinh province.
The project, located within the Vung Ang Economic Zone, aims to install 43 megawatts of rooftop solar power and 45 megawatt-hours of battery storage across three Vingroup manufacturing plants. The operational timeline for the project has not been disclosed, with similar projects taking 12-18 months from agreement signing to full commissioning.
The Ha Tinh project is part of Vingroup's goal of achieving net-zero emissions by 2040, a decade ahead of Vietnam's national timeline. The project is expected to generate 50 million kilowatt-hours annually and cut CO2 emissions by 33,000 tonnes per year. Industry experts estimate the project's capital investment to be between $35-50 million.
The project will utilize Vietnam's first Direct Power Purchase Agreement (DPPA) model for combined solar and battery storage. Under this model, renewable energy producers can sell power directly to corporate consumers, bypassing some traditional grid bottlenecks. This approach could influence the adoption of similar strategies in other Vietnamese industrial zones.
However, Vietnam's rapid renewable expansion has outpaced its aging electrical grid, creating new challenges. Grid congestion and renewable energy curtailment have become persistent problems, and the Ha Tinh project enters a market where infrastructure constraints could complicate ambitious timelines.
Despite these challenges, the Ha Tinh project is a significant step towards Vietnam's clean energy future. The project's projected environmental impact matches roughly 0.2% of Vietnam's current solar capacity, raising questions about its scale. Yet, it is an untested approach in Vietnam, with VinEnergo's rooftop solar-plus-storage strategy relatively uncharted territory in the country.
VinEnergo's track record in delivering large-scale renewable projects is limited compared to established players in Vietnam's energy market. However, the success of the Ha Tinh project could pave the way for more private investment in clean energy, aligning with new government policies designed to support Vietnam's transition away from coal.
Energy demand in Vietnam increased 10.9% in the first nine months of 2024, underscoring the need for sustainable energy solutions. The Ha Tinh project is part of a broader nationwide strategy for integrated clean energy solutions, with the outcome potentially highlighting the challenges facing ambitious renewable energy timelines in a grid-constrained market.
As the Ha Tinh project moves forward, it will be interesting to see how it contributes to Vietnam's renewable energy landscape and whether it serves as a model for future clean energy projects in the country.
