On the afternoon of November 21, 2025, in Hanoi, GG Industries Joint Stock Company and Widex Solar Group Joint Stock Company officially signed a Memorandum of Understanding (MOU) to collaborate on the development of rooftop solar power projects integrated with Battery Energy Storage Systems (BESS).
The signing marks a strategic move to expand renewable energy models with integrated storage — a fast-growing trend in Vietnam, as the demand for stable power supply for industrial production continues to rise.
Strengthening Cooperation to Effectively Harness Renewable Energy
Under the MOU, the two companies will collaborate to identify, evaluate, and implement rooftop solar projects integrated with energy storage systems, aiming to optimize electricity usage and maximize the operational value of each project.
GG Industries will be responsible for delivering end-to-end technical solutions, including technology, equipment, and support services for BESS systems. The company is actively promoting a localization strategy for key components of the storage system, helping reduce costs and ensure supply chain autonomy.
Widex Solar, on the other hand, will take the lead in project development and management, while closely working with GG Industries to integrate customized energy storage solutions tailored to the specific needs of each client.
Targeting 300 MWp of Rooftop Solar with BESS Within Three Years
Between 2025 and 2028, the two parties aim to jointly develop approximately 300 MWp of rooftop solar capacity integrated with energy storage systems. This is considered a high-potential segment, as more manufacturing enterprises are seeking solutions to reduce electricity costs and ensure load stability.
A representative from GG Industries shared that the combination of the company’s production and engineering capabilities with Widex Solar’s project development experience will enable the creation of highly applicable renewable energy models — particularly suited for industrial zones.
Meanwhile, Widex Solar noted that integrating energy storage into solar power projects will significantly enhance energy utilization efficiency. It also enables businesses to take greater control of their electricity supply, especially in the context of rapidly increasing demand and growing pressure to reduce carbon emissions.
Contributing to the Energy Transition
The partnership between these two domestic enterprises comes at a time when the Vietnamese Government is actively promoting self-generation and self-consumption energy models integrated with storage systems. This initiative aims to increase the share of renewable energy in the national grid and reduce pressure on the power transmission infrastructure.
The MOU is expected to contribute to the advancement of more efficient clean energy models, while also opening up new investment opportunities in the renewable energy and energy storage sectors in Vietnam.
