Abstract

A TidalPowerPlant (TPP) is being constructed in the middle section of the existing LakeSihwa dike located near the southern Incheon Port in Korea. The project, which will be completed in 2010, is to harness the largest tidal energy in the Kyeonggi Bay in the eastern Yellow Sea. While noting the current progress in terms of plant construction, this paper outlines the overall project in the tidal regime and uses predictive local flow modeling. The results of two-dimensional finite element method simulations that predict the real-time tidal characteristics during the construction and after the completion of the tidalpowerplant are presented, including a method to estimate the electricity output from the plant in the future.
