The Incheon Tidal Power Station is a large tidal power station proposed for Incheon Bay, South Korea. The facility is designed to top 1,320 megawatts (1,770,000 hp) in generating capacity with the help of 44 water turbines rated at 30 megawatts (40,000 hp) each, which would make this facility the largest of its kind in the world. The construction and developments costs are expected to reach ₩3.9 trillion (US$3.4 billion), of which would be entirely covered by private funding. The station is expected to generate up to 2.41 TWh of energy annually.

Planning for the project was halted in 2012 following environmental concerns since then there has been no news as to when it might proceed or be formally cancelled.
