This latest phase adds 26.8 MWp of installed capacity to the company's integrated steel complex, representing a substantial commitment to industrial decarbonisation within Southeast Asia's rapidly growing steel sector. Once commissioned, the third phase is expected to generate approximately 42.8 million kWh of renewable electricity annually and reduce carbon dioxide emissions by nearly 28,200 metric tons per year . This emissions reduction is particularly significant given the energy-intensive nature of steel production, where traditional processes rely heavily on fossil fuels for both power generation and process heat. The project's progression demonstrates Hoa Phat's dedication to its long-term development strategy, compliance with environmental, social, and governance standards, and alignment with the global energy transition. The company has emphasised that expanding the use of renewable energy has become an increasingly important strategy for steelmakers seeking to enhance competitiveness and comply with tightening environmental requirements in both domestic and international markets . Hoa Phat Dung Quat Steel began investing in the rooftop solar project in 2025 with a total investment of VND 600 billion, equivalent to approximately $24.3 million USD at current exchange rates, representing one of the largest industrial solar investments in Vietnam's manufacturing sector.

Dung Quat's Dual Decarbonisation & Solar Self-Sufficiency's Strategic Significance

The Dung Quat integrated steel complex serves as the epicentre of Hoa Phat's renewable energy strategy, leveraging the extensive rooftop area of its production facilities to capture solar energy for its operations. The project's phased approach reflects careful planning and execution, with phases one and two already installed in November 2025 and March 2026 respectively, demonstrating the company's ability to deliver complex infrastructure projects on schedule . The third phase's construction commencement in July 2026 maintains this momentum, with the entire project scheduled for completion in the second quarter of 2027. The planned total capacity of 79.2 MWp positions this initiative as one of the largest rooftop solar projects in Vietnam's industrial sector, a distinction that underscores Hoa Phat's leadership in industrial decarbonisation . Upon completion, the full project is expected to generate more than 115 million kWh of clean electricity annually and reduce carbon dioxide emissions by more than 78,000 metric tons per year . This renewable electricity generation will increase the company's self-sufficiency in renewable power, reducing its dependence on Vietnam's national grid, which remains heavily reliant on coal-fired generation. The energy self-sufficiency aspect is particularly valuable for steelmakers, who face significant energy cost pressures due to the electricity-intensive nature of electric arc furnace steelmaking and other production processes. By generating its own renewable electricity, Hoa Phat can stabilise its energy costs while improving its environmental performance, creating a competitive advantage in both domestic and export markets.

Horus Power's Harmonious Partnership & Technical Expertise's Transfer

Hoa Phat's collaboration with partner Horus Power represents a strategic alliance that leverages specialised expertise in renewable energy project development and implementation. Horus Power brings technical knowledge in solar photovoltaic system design, installation, and maintenance, complementing Hoa Phat's operational expertise in steel production. The partnership structure enables Hoa Phat to focus on its core steelmaking activities while benefiting from Horus Power's renewable energy capabilities, creating a symbiotic relationship that accelerates the project's implementation. The 600 billion VND investment is being deployed across five phases, with each phase building on the learnings and operational experience of its predecessors. This phased approach allows for continuous improvement in installation techniques and system performance, ensuring that each subsequent phase benefits from the knowledge gained in earlier installations. The collaboration also facilitates the transfer of technical knowledge to Hoa Phat's engineering teams, building internal capabilities for future renewable energy projects. This knowledge transfer is essential for the long-term sustainability of Hoa Phat's decarbonisation efforts, enabling the company to maintain and expand its renewable energy infrastructure independently. The partnership structure demonstrates how industrial companies can effectively collaborate with specialised renewable energy firms to accelerate their energy transition, creating a model that other steelmakers could potentially replicate in their own decarbonisation efforts.

Compliance's Competitive Catalyst & ESG's Essential Embrace

The Hoa Phat rooftop solar project responds to multiple pressures shaping the global steel industry, including tightening environmental regulations, increasing customer demand for sustainable products, and the growing importance of ESG performance for investors and financiers. Vietnamese steelmakers face increasing scrutiny from both domestic authorities and international customers, particularly those exporting to markets with stringent environmental requirements. The European Union's Carbon Border Adjustment Mechanism, which entered its definitive compliance phase on 1 January 2026, imposes carbon costs on imported steel, creating a competitive disadvantage for producers unable to demonstrate low-carbon production. Hoa Phat's investment in renewable energy represents a proactive response to this regulatory pressure, reducing the carbon footprint of its steel production and thereby minimising potential CBAM liabilities. The project also supports compliance with Vietnam's own environmental regulations, which are becoming increasingly stringent as the country pursues its commitments under the Paris Climate Agreement. The expansion of renewable energy use has become an increasingly important strategy for steelmakers seeking to enhance competitiveness and comply with tightening environmental requirements in both domestic and international markets . This recognition reflects a broader industry understanding that environmental performance is no longer a matter of corporate social responsibility but a fundamental driver of commercial success.

Financial Feasibility's Favorable Factors & Operating Cost's Optimisation

The rooftop solar project delivers compelling financial benefits that extend beyond environmental compliance, creating a strong business case for investment in renewable energy infrastructure. The generation of 42.8 million kWh annually from the third phase alone represents substantial electricity cost savings, particularly given Vietnam's industrial electricity tariffs, which have been subject to periodic increases. The project's total capacity of 79.2 MWp, generating more than 115 million kWh of clean electricity annually, will provide significant operating cost reductions across the Dung Quat complex. These savings are particularly valuable in the steel industry, where energy costs typically represent a significant proportion of total operating expenses, often ranging from 20-40% depending on the production route and energy prices. The project's 600 billion VND investment is expected to deliver attractive returns through reduced electricity costs, while also providing hedge against future electricity price increases. The financial benefits extend beyond direct energy cost savings to include potential revenue from carbon credits, which could be generated and sold in voluntary carbon markets. Hoa Phat's investment in renewable energy also enhances the company's access to green financing, as financial institutions increasingly offer preferential terms for projects with demonstrated environmental benefits. The project's favourable economics, combined with its environmental benefits, create a compelling investment case that supports Hoa Phat's long-term competitiveness and profitability.
