This research analyzes the vision of NSWPH for a North Sea energy island using environmental planning methods. It follows the backcasting method’s four phases to establish visions, identify measures, and analyze EU directives. The Baseline phase creates a bidding zone, addresses challenges, and examines the energy market. Proposed solutions include bidding zone review, grid expansion, and Power To X implementation for a sustainable EU energy system and island development. Implementation is crucial for a sustainable EU energy system and island development.
