Energy system planning addresses the need for new capacities in generation and transmission facilities. Although this problem has been solved sufficiently well in the past, with the transition towards renewable energy-based generation, the necessity to incorporate operational flexibility has increased the computational resources required to solve this problem. Therefore, this thesis presents computationally efficient solution methods to enable operational flexibility in the planning context by proposing a decomposition framework to decompose the problem, and several other algorithms: grouping and branching to improve the performance of the framework, and adaptive time resolution approach to mitigate the requirement for high temporal resolution.
