The goal is to come up with a feasible, cost-effective and lasting solution, that can store green energy, pump out 10 000 m3/s of water and retain design storms, the classic design steps are followed. The method followed, starts with an analysis of the problem, giving insight to the relevant stakeholders and functions that should be included. These elements lead to the Program of Requirements, which contains research into the tailor-made pump-turbine system and present-day water levels. The analysis ends in presenting the boundary conditions. This thesis continues with several concepts that fulfil the functions and requirements. For those concepts, the possible construction methods are described, and checks are performed to verify the stability, including 1) piping, 2) rotational stability, 3) sliding, 4) bearing capacity and 5) (static) floating stability. Using the evaluation criteria from the analysis, described after the Program of Requirements, and weighting factors, following from the stakeholder analysis, the value of the different alternatives is calculated via a Multiple-Criteria Decision Analysis and compared to each other, by including costs. Lastly, one more iteration is made to check the strength of the walls and floors of the most desirable alternative. It can be concluded that the most straightforward alternative, called `Unity', is more cost-effective than an alternative integrated into the dune surrounding the energy storage lake. Also, the minimum width of that caisson, which is 53 m and follows from the pump-turbine system, can be achieved according to the stability checks. The author recommends checking the interaction between the spillway and the in- and outlet structure and model the foundation of the caisson more thoroughly.
