The world’s largest tidal power plant, Sihwaho Tidal Power Plant produces enough electric power to serve 500,000 people a year. The tidal power plant uses the gap between the water level of tide and ebb to produce energy. As Sihwa lake has a water level gap of nine meters, it is an optimal place for tidal power generation.
The Sihwaho Tidal Power Plant can be seen from T-Light Park, which was made out of the sand that was excavated while building the power generator. The park is home to restaurants, coffee shops, the ocean view plaza, and the light obelisk tower. It also hosts various performances, establishing itself as a must-see tourist attraction on Daebu Island.
