Gunsan Power Plant222 MW Coal

CoalVerified: Feb 2026

The Gunsan Power Plant, known locally as 한화에너지 군산공장, ranks as the 135th largest power generation facility in South Korea. With a capacity of 222 MW, it contributes a modest 0.09% to the country's total energy production, which amounts to 256,029 MW across 265 plants. This plant is notable for its reliance on coal, placing it as the 34th largest among 38 coal facilities in South Korea. The coal-fired generation technology utilized here is essential for providing baseload power, although it faces increasing scrutiny due to environmental concerns. Gunsan is surrounded by several significant coal plants, including the massive Boryeong Power Plant and its counterparts, which boast capacities of 5,350 MW and 4,000 MW respectively. This clustering of coal facilities underscores the region's heavy reliance on fossil fuels for energy production. In contrast, Gunsan’s relatively small capacity reflects the ongoing challenges faced by smaller operations within a landscape dominated by larger coal plants, which can better leverage economies of scale. South Korea's energy profile is heavily reliant on coal, making up a significant portion of the country's energy mix. With the government pushing for a transition towards cleaner energy sources, the role of Gunsan Power Plant is increasingly under evaluation. As part of a broader initiative to diversify energy sources, the plant's operator, 한화에너지, is tasked with adapting to new regulations and environmental standards that are shaping the future of energy production in the country. Looking forward, Gunsan Power Plant stands at a crossroads. While it continues to provide essential energy to the grid, its future will likely be influenced by the national drive toward renewable energy and reduced carbon emissions. The plant's ability to adapt to changing energy policies will be crucial as South Korea navigates the complexities of its energy transition.
