Exploring the offshore wind and wave generation complementarity in Portugal for a sustainable and resilient power system

ABSTRACT: Exploring variable energy sources generation complementarity can, among several benefits, help in the reduction of the negative impacts of variability from individual sources, and lower the system’s flexibility requirements. This study focuses on the complementarity between offshore wind and wave energy aiming to identify its overall value to the power system. Using Portugal as a case study, this work examines two offshore regions of the Plan for the Allocation of Offshore Renewable Energy in Portugal using standard approaches to assess the level of complementarity. The findings show a clear seasonal mismatch in the summer between wind and wave energy, which supports their complementary nature and helps smooth out seasonal fluctuations in offshore renewable generation. The results indicate that wave energy brings value to diversifying the offshore energy mix. When compared with onshore renewable generation, the combined use of offshore wind and wave power significantly enhances the stability of energy supply, reduces extreme events, which can contribute to decrease the need for additional system flexibility in future nearly 100% renewable-based power systems.

ABSTRACT: This document is related to Deliverable 3.1 of the Man0EUvRE project, in which we report modelling activities of nine case studies from various countries. Each case study addresses a question from a regional perspective while considering the general assumptions of the consortium through established scenarios. We follow a consistent reporting format across all case studies, allowing readers who are interested in a specific region or question to skip other cases without losing essential context. Based on our preliminary findings, European energy systems across the case studies collectively show that Europe can become both self-reliant and an exporter of low-carbon energy carriers if policies and investments unlock regional strengths and the right flexibility instruments are put in place. Southern states with abundant solar energy (e.g., Portugal, Spain, Greece, Turkey) can scale renewables and electrolysis. Scandinavia’s hydropower offers system-scale flexibility that stabilises high variable renewable energy (VRE) penetration, and cross-model comparisons demonstrate that combining broad, cross-sectoral modelling with detailed power-system studies reveals complementary roles for exports, seasonal storage and short-term balancing. Studies of Germany and Hungary underline the critical role of dispatchable, negative-emission options—such as bioenergy with carbon capture and storage (BECCS)—to avoid reliance on fossil backstops, while agent-based macroeconomic results show that changing global energy factor prices will reshape (not necessarily hollow out) industrial activity.
