The Kyunggi Bay is famous for its large tidal amplitude in the Yellow and East China Seas and some effort is made to use the large tidal energy for the generation of the electricity. Siwha tidal power plant with capacity of 254 Mw is being built inside the Kyunggi Bay and it will be completed by 2010. Again feasibility study with much larger capacity of power is being carried out in the neighboring site named as Inchon Bay. Both medium and large scale of tidal power generation schemes are under consideration for the Inchon Bay.
