The Background
This Taean-based project is South Korea’s largest single onshore solar power plant, and is a bold step in the country’s renewable energy journey. Over the next 25 years, it is projected to generate 7,200 GWh of clean energy—offsetting more than 7.15 million tons of carbon emissions. It’s a commitment to South Korea’s clean energy transition, and a major milestone for its sustainable energy infrastructure
The Challenges
Located near the coast, the site presented significant exposure to salt corrosion—a major risk to conventional power infrastructure. The project was also the first in South Korea to undergo rigorous on-site testing aligned with the country’s evolving technical grid standards, which called for reliable, compliant performance under strict regulatory conditions.
The Solution
To overcome these challenges, Sungrow deployed IP65-rated equipment capable of withstanding humidity and salt corrosion. Our team also implemented advanced grid support features, including Low and High Voltage Ride-Through (LVRT/HVRT) and reactive power control, to ensure compliance and pass on-site tests. Another key factor was the flexible design of our 1+X modular inverter, which enabled a streamlined system architecture, lowered costs, and provided greater adaptability.
The Impacts
More than just a technical success, this project marks a meaningful step toward South Korea’s sustainability goals. By strengthening national energy security, reducing emissions, and supporting the transition to renewables, it serves as a powerful example of the country’s commitment to clean energy. With Sungrow’s solutions at its core, the project also sets the stage for greater energy self-reliance in the years ahead.
