NOVELTY - The power plant has a water gate unit (1) installed at sea and land. A traffic lane is provided in water gate unit, for controlling the flow of water. A drag net (3) is installed to block the suspended material flowed into a generation unit (2). The water gate unit, the generation unit, and the safety unit are dried in the land or sea. The generation unit is installed in traffic lane, to produce the electric power by the flow of water in the aquatic structure.    USE - Power plant e.g. not in my backyard (NMBY) nuclear power plant, thermal power plant, hydroelectric power plant, solar power plant, wind power plant and tidal power plant.    ADVANTAGE - The construction period and the destruction of nature according to the power plant construction can be prevented. Since electricity is produced using natural resource, the NIMBY can be prevented. Since generation unit is operated with the flow of the flowing water, the destroy of power plant and aquatic structure due to flow of ebb tide and high tide of the sea. Hence the environment-friendly power plant is obtained. As the power plant and aquatic structure is connected with the tourist industry, the local development can be planned effectively. Since the water gate unit is connected to the bank to the land, the need for using public transportation can be avoided. Hence the tourist is conveniently moved to the power plant and aquatic structure. The sightseeing nature can be maximized. As the water gate pillar fixes the water gate column of the water gate unit on the bottom surface of the water gate unit, the power plant and aquatic structure can be installed conveniently. The suspended material flowed into generation unit can be blocked effectively. As the scour protection unit is installed at the bottom surface of the water gate unit, the power plant and aquatic structure can be safely protected from flow of water. As the vessel path is installed at the ship movement unit, the safety about the vessel can be improved.
