TotalEnergies ENEOS has commissioned a nearly 28 MWp rooftop photovoltaic system at Samsung Electronics' Ho Chi Minh City complex, the first private project under Vietnam's Decree 57 direct power purchase agreement framework.
TotalEnergies ENEOS has commissioned a nearly 28 MWp rooftop photovoltaic (PV) system at the Samsung Electronics HCMC CE Complex (SEHC) in Ho Chi Minh City, Vietnam. The installation is the first and largest rooftop solar project concluded under a private direct power purchase agreement (DPPA) framework governed by Vietnam’s Decree 57, via a private-wire arrangement. The commissioning ceremony was attended by representatives from local authorities and project partners.
Under this 20-year power purchase agreement (PPA), TotalEnergies ENEOS financed, installed and now operates and maintains the system on behalf of Samsung Electronics. The SEHC complex is Samsung Electronics’ second largest global manufacturing site, according to information provided by the parties. The project incorporates close to 45,000 PV modules and generates over 40,000 MWh of renewable electricity annually, covering approximately 26% of the site’s electricity consumption.
Over the contract period, the system would avoid more than 500,000 tons of CO₂ emissions, according to TotalEnergies ENEOS. The installation would also reduce heat gain from covered roof areas, improving the site’s overall energy efficiency. The growth of industrial rooftop solar is visible across multiple markets, as illustrated by the 1.9 MWp solution deployed by Alight for ITP Aero at its Nottinghamshire plant.
The project supports Samsung Electronics’ RE100 commitments, an international initiative requiring 100% renewable electricity sourcing. Alexandru Buzatu, Director of TotalEnergies ENEOS Renewables Distributed Generation Asia Pacific, stated that the project’s successful delivery “reflects strong collaboration” and demonstrates how onsite solar can support industrial decarbonization “while upholding high safety and quality standards throughout.” Keunha Hwang, President of the SEHC complex, described the project as a “significant milestone” in SEHC’s transition toward renewable energy.
The use of Decree 57 under a private-wire arrangement opens a new avenue for industrial operators seeking to secure renewable energy supply in Vietnam. This dynamic is part of a broader trend across Southeast Asia, where demand for decentralised solar accelerates, notably in the Philippines, which have become the world’s top solar market amid soaring electricity prices. The project’s completion highlights the opportunities that DPPA frameworks offer for large-scale manufacturing sites across the region.
