Hoa Phat Dung Quat expands rooftop solar projec

Hoa Phat Dung Quat Steel JSC (HPDQ) has begun construction of phase two of its rooftop solar power project, developed in partnership with Horus Power JSC (HRP), with a total installed capacity of 22.5 MWp.

The project is part of the company’s efforts to increase its use of clean energy, reduce production costs and support environmental protection by cutting carbon emissions.

Phase two of the rooftop solar system has a total installed capacity of 22.5 MWp, marking a significant step in expanding clean energy use at the facility.

The rooftop solar project at HPDQ has a total investment of nearly VNĐ600 billion and is divided into five phases, with a combined capacity of 79.2 MWp. It is scheduled for completion by the second quarter of 2027. Once fully operational, the system is expected to generate more than 115 million kWh of clean electricity annually, reducing over 78,000 tonnes of CO₂ emissions each year. It is among the largest rooftop solar installations on industrial facilities in Vietnam.

The first phase, with a capacity of 5 MWp, was launched in November 2025. Building on that progress, phase two is now underway and is expected to generate around 32.8 million kWh of clean electricity per year, helping increase the share of green energy and further strengthening the plant’s energy self-sufficiency.

Phase two of the rooftop solar system is expected to generate approximately 32.8 million kWh of clean electricity annually, boosting the plant’s green energy supply.

The solar panels are being installed across multiple facilities, including rolling mills 1 and 2, the hot rolled coil (QSP) plant, metal warehouses, technology storage areas, as well as water treatment and reservoir systems.

Hoang Ngoc Phuong, Deputy Director of the company, said the rooftop solar project reflects HPDQ’s commitment to adopting cleaner energy solutions.

“We expect this phase to build on the success of the first, delivering practical benefits in terms of cost efficiency while creating added value for the environment and the community,” he said.

The system uses N-type TOPCon solar panels combined with high-efficiency inverters to optimise power generation and ensure a stable electricity supply for production lines. Phase two alone is expected to cut more than 22,000 tonnes of CO₂ emissions annually, supporting greener and more sustainable manufacturing while enhancing the company’s competitiveness, particularly in export markets such as the EU.

Hoa Phat Group is currently the largest steel producer in Southeast Asia, with total capacity projected to reach 16 million tonnes per year by the end of 2026. The Dung Quat steel integrated complex accounts for 12 million tonnes annually.

In 2025, HPDQ generated 2.85 billion kWh of electricity in-house, meeting around 90 per cent of its production demand through solutions such as waste heat recovery, environmentally friendly dry quenching technology and continuous casting and rolling processes.
