The Siwha Lake Tidal Power Station is a key infrastructure asset in South Korea's power generation grid, located on the continent of Asia. Designated as a renewable electricity generation station, the facility features an installed capacity of 254 MW. Its primary operation relies on harnessing wave and tidal energy resources to generate bulk electricity. Operational management and ownership of the facility are handled by the 한국수자원공사, which oversees daily maintenance and grid dispatch integration. An exact commissioning date for the installation is not registered in official historical logs. In terms of domestic production capacity within South Korea, Siwha Lake Tidal Power Station occupies the #1 position among all operational wave and tidal power plants. Its 254 MW capacity represents a 33.33% share of South Korea's total installed wave and tidal generating capacity, which currently stands at 762 MW. Notably, this facility currently stands as the largest active wave and tidal power installation in South Korea, serving as a benchmark for localized wave and tidal technology deployment. Across all fuel types and electricity generation technologies country-wide, this facility accounts for 0.0993% of South Korea's aggregate generation capacity of 255,681 MW. Based on historical capacity factors characteristic of wave and tidal power plants (modeled at 30% for analysis), the facility's expected annual electricity generation is calculated at approximately 667,512 MWh. Applying domestic consumption statistics where an average household in South Korea consumes 3 MWh of electricity annually, this level of production is sufficient to meet the energy demands of roughly 222,504 homes. As a clean and sustainable energy project, Siwha Lake Tidal Power Station contributes to the direct displacement of greenhouse gases, preventing substantial quantities of carbon dioxide from entering the atmosphere and helping South Korea advance toward its renewable energy integration targets. The physical site of the station is located at geographic coordinates 37.3135° latitude and 126.6126° longitude. Analysis of local grid infrastructure shows a density of other assets within a 50-kilometer radius. These nearby facilities include the Taean Thermal Power Plant (gas-fired, 6446.33 MW), the Dangjin Power Station (coal-fired, 6040 MW), the Dangjin Thermal Power Station (coal-fired, 6040 MW), representing a cluster of localized power assets. This geographic placement is vital for reinforcing regional distribution infrastructure and minimizing transmission line losses across this sector of South Korea.

Wave and Tidal Power Generation: An Overview of Marine Renewable Energy
Wave and tidal energy are forms of marine renewable energy harnessed from the movement of water. Wave energy is derived from the surface motion of the ocean, while tidal energy is generated from the gravitational pull of the moon and sun, which causes periodic changes in sea levels. These energy sources are increasingly recognized for their potential to contribute to a sustainable energy future. As of now, there are approximately ten wave and tidal power plants worldwide, located across four countries, with a total installed capacity of about 0.6 gigawatts (GW). The leading nations in this domain include South Korea with one plant generating 0.3 GW, France with one plant producing 0.2 GW, the United Kingdom hosting seven plants with 0.0 GW, and Canada with one plant also at 0.0 GW.
