TotalEnergies ENEOS Powers Samsung With 28-MWp Rooftop Solar

• TotalEnergies ENEOS powers Samsung Vietnam with nearly 28 MWp rooftop solar under a 20-year PPA—over 40,000 MWh yearly, cutting 500,000+ tonnes CO2 and fueling Samsung’s 100% renewables push.

TotalEnergies ENEOS has commissioned nearly 28 MWp of rooftop solar at Samsung Electronics’ manufacturing hub in Vietnam, the company said. The Vietnam plant will supply Samsung with more than 40,000 MWh of renewable electricity each year through a power purchase agreement.

The 20-year PPA was tied to Samsung’s HCMC CE Complex in Ho Chi Minh City, covering about 26% of the site’s electricity use and avoiding more than 500,000 tonnes of CO2 emissions over the contract term. TotalEnergies ENEOS financed, built, and will operate and maintain the facility equipped with roughly 45,000 PV modules, supporting Samsung’s push for 100% renewable power. The firm plans to deploy 2 GW of decentralised solar across Asia by 2030, after starting construction in April 2025.

How will TotalEnergies ENEOS’ 28 MWp rooftop solar PPA cut Samsung Vietnam emissions?

• Supplies clean electricity to Samsung’s Vietnamese manufacturing operations under a long-term PPA, displacing electricity that would otherwise be generated from fossil fuels in the grid.
  
• Enables Samsung to replace a measurable share of onsite electricity consumption (about one-quarter of the referenced complex’s demand), which directly reduces the site’s scope 1/2–related emissions depending on Samsung’s accounting approach and the contract structure.
  
• Cuts greenhouse-gas emissions over the 20-year contract period by locking in renewable generation versus ongoing “business-as-usual” grid power use.
  
• Avoids emissions by matching continuous industrial electricity demand with contracted solar output, reducing the amount of energy procured from higher-carbon sources during operating hours.
  
• Delivers renewable electricity volumes of more than 40,000 MWh per year, supporting annual reductions and improving trajectory toward the company’s broader renewable electricity goals.
  
• Reduces operational carbon intensity at the plant level because the generated power is produced on-site, meaning less reliance on centralized power generation that often has higher average emissions.
  
• Improves emissions reporting clarity for Samsung by providing a contractual, measurable renewable energy supply (metered/credited through the PPA), making annual decarbonization targets easier to audit.
  
• Creates additional, near-term decarbonization impact through commissioning and operation of distributed rooftop capacity rather than waiting for future grid-scale projects.
  
• Supports lower lifecycle emissions compared with fossil alternatives by using solar photovoltaic generation with no direct combustion emissions during operation.
• Provides long-duration certainty: the 20-year structure helps sustain emission reductions consistently through the contract term, rather than relying on short-term renewable procurement.
