TotalEnergies has partnered with Daehwa Pharmaceutical to develop and supply 2.2 megawatts (MW) of solar energy from a new rooftop installation. This project, located at Daehwa’s pharmaceutical production plant in Osong, is expected to reduce carbon emissions by 1,600 tons annually.
Rooftop Solar System at Daehwa’s Osong Plant
This 2.2 MW solar power plant project is set to deliver annual carbon emissions savings of 1,600 tons—equivalent to planting 16,000 trees—and generate significant electricity cost savings. Under the agreement, TotalEnergies will design, install, and maintain the system, while Daehwa will use the clean energy it produces.
“We will continue to take the lead in eco-friendly management by using renewable energy, such as solar power, while striving to improve the health of the people through the development of new drugs,” said Yoon Chang-joon, CEO of Daehwa Pharmaceutical.
TotalEnergies Expands Solar Projects in Korea
This partnership is part of TotalEnergies’ active expansion of its solar power business in Korea. The company recently signed a 4.4 MW solar power supply contract with Daehan New Pharm and also completed the world’s largest floating solar power plant, which generates 10 MW of electricity annually.
Built on a reservoir in the Netherlands, that floating solar project uses specialized modules to maximize space and energy efficiency, producing enough power for approximately 4,000 households. Similar initiatives include the Bahamas solar power agreement and the Suriname solar park launch, both marking significant steps towards sustainability.
TotalEnergies’ Global Renewable Energy Goals
TotalEnergies aims to become a global leader in renewable energy, particularly solar, with a target of 100 GW of renewable capacity by 2030. The company is expanding its solar and wind portfolios worldwide, with major projects underway in India, the U.S., and Europe.
In the U.S., TotalEnergies partnered with SunPower on large-scale solar projects and acquired a 50% stake in a 2.2 GW portfolio of solar and energy storage assets from SunChase Power and MAP Energy. The company’s global efforts also include investments in solar thermal technology in China.
