Barrage for energy extraction from potential energy contained in ocean tides, consists of multiple support stands installed with the same interval from each other in the ocean along the perimeter line and attached to the sea bottom. Panels are installed one above the other and fixed between pairs of neighboring support stands. Gaps between every panel and support stands are leak-tightened. Pairs of support stands from two rows of support stands for caissons. Support panels are placed between every pair of opposite support stands from the mentioned two rows so that caisson is supported by support panels, so that they form platform between two rows for caissons. In every caisson there are turbines with facilities that provide for water passing through the turbine by operator command. Electric generators are connected to at least one turbine. Barrage has no gaps or slots. As a result the ocean is separated from the area inside the barrage, excluding time, when operator provides water passing through turbine for electric power generation.
