Together with students, Delta21 developed an integral concept focusing on renewable energy, flood safety and nature restoration. It is a concept applicable at dozens of locations worldwide in and around estuaries, but further elaborated together for the south-western delta near the Haringvliet.

At this specific location, it not only addresses important elements of the National Climate Agreement, but also offers an alternative to the damage to the river landscape caused by dyke reinforcement. With the pumping capacity needed to discharge excess river water to the North Sea in case of emergency, a large-scale "battery" to store sustainable electrical energy will also become available, making the plan economically very attractive.

If the Delta21 plan is realised, the Energy Storage Lake can be drained at any time with the excess wind and solar energy and, when the demand for electric power increases, function as a power plant. Due to its strategic location against Maasvlakte 2 and near the landfall of the BritNed cable, it can also add a mega-grid and requires hardly any cost to connect to the Dutch power grid.

However, if during a heavy storm, high river discharge or a combination of both, the water level in the area from Gorinchem to the sea continues to rise, the excess river water can be pumped directly to the North Sea at a flow rate of about 10 thousand m3/s.
