Industrial parks across Vietnam are increasingly adopting rooftop solar systems and battery energy storage solutions to improve energy security, reduce electricity costs and support sustainability objectives. The shift comes amid rising energy price volatility, growing emissions reduction requirements and increasing demand for long-term energy independence in the country’s industrial sector.
According to industry estimates, businesses can reduce electricity costs by between 20% and 40% through rooftop solar installations, with average investment payback periods of four to six years and system lifespans extending up to 30 years. Major industrial parks have already deployed large-scale systems, including approximately 90 MWp of rooftop solar capacity at Thang Long Industrial Park in Hanoi, which has been operating since 2021. Industrial parks such as Amata Industrial Park in Dong Nai Province are also expanding renewable energy deployment as companies seek to comply with environmental, social and governance requirements and strengthen supply chain competitiveness.
Industry stakeholders noted that battery energy storage systems (BESS) are becoming increasingly important to complement solar generation by storing excess electricity for use during higher-cost periods and addressing intermittency challenges. The development supports Vietnam’s broader energy transition efforts and the creation of more sustainable and flexible industrial ecosystems capable of supporting long-term manufacturing growth.
