- Contribution to the Development of a New Value Chain in the Marine Renewable Energy Sector [Resumo]Publication . Fontes, Margarida; Simões, Teresa; Estanqueiro, Ana; Nieto, Felix; Tsami, MariaABSTRACT: As part of the commitments made in the NECP2030 for Portugal, an increase in wind capacity is planned, including an additional 10.4 GW onshore and 2 GW offshore. In this sense, it is necessary to assess the conditions for the creation of a new industrial value chain that will accelerate this development and offer attractive conditions for the involvement of the industrial sector, providing conditions for the objectives recommended in the NECP 2030 to be met. Projects OffshorePlan - Planning for the Use of Offshore Renewable Energies in Portugal, and OceanTrans - Ocean energy technologies transformative potential analyzed the relevant socio-economic component for this sector, namely the process of creating a new industrial value chain to support the development of marine renewable energies. As part of this research, a questionnaire survey was conducted targeting companies in sectors with complementary skills and resources, directly or indirectly related to the development of projects in this area. The questionnaire yielded 114 responses from companies already active and 182 from companies willing to become involved in the future. The results allowed us to obtain a global view of the actual and potential involvement of the industrial sector, as well as to gain some insight into how companies view the requirements to operate in this area and the main barriers to their performance. This article presents the main findings obtained in the scope of this research and discusses their contribution to the advancement of the marine renewable energy sector and, as such, to the development of offshore wind energy in Portugal.
- Exploring the Offshore Wind and Wave Generation Complementarity in Portugal for a Sustainable and Resilient Power System [Resumo]Publication . Couto, António; Justino, Paulo Alexandre; Costa, Paula Silva; Simões, Teresa; Estanqueiro, AnaABSTRACT: 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.
- Offshore Wind in Portugal: Actual Situation and Future Perspectives [Resumo]Publication . Estanqueiro, Ana; Rebelo, Carlos; Baniotopoulos, Charalampos; Malekjafarian, Abdollah; Glumac, Anina; Marino, Enzo; Nieto, Félix; Hemida, Hassan; Gervásio, Helena; Tesch, Luana; Tsami, Maria; Gkantou, Michaela; Borg, Ruben Paul; Simões, Teresa; Tankova, TrayanaABSTRACT: Portugal started the deployment of wind energy onshore in the early nineties, along with the majority of the European countries and soon became one of the countries with a highest share of wind in the electric energy mix. However, unlike northern “wind countries” the offshore deployment didn’t follow the onshore success story. There are several reasons for that, the most important being the bathymetry of the Portuguese Coast, that prevents the installation of the common fixed to the bottom offshore foundations. To overcome that limitation, Portugal had a very active role in the deployment of the offshore floating technology, being the second country in the world to develop, construct and operate a successful floating wind turbine, WindFloat and, shortly after, a floating wind plant, Wind Atlantic. Those projects demonstrated the adequacy of the floating technology for the existing offshore conditions while recent projects, e.g. PO SEURE OffshorePlan, were characterizing the estimated wind potential and indicated possible planning and deployment paths. In 2022, the Portuguese government created an offshore working group (through Despacho n.º 11404/2022) with the mission to: i) identify the optimal locations, i.e. having a higher estimated potential, a lower impact on the environment and maritime activities while enabling the connection to the existing onshore grid – those areas were finally approved in February 2025; ii) address the most adequate competitive models for the sea-use concessions; and iii) characterize the capacity of Portuguese ports to support the deployment of the wind offshore sector. In 2024, the Portuguese Government announced it would initiate the auction for offshore wind plants still in 2025. The presentation addresses the planning work of the recent years and indicates the next steps for the deployment of the offshore wind sector in Portugal.
- The reform of Balancing Markets: Insights from Portugal and Spain [Abstract]Publication . Algarvio, Hugo; Couto, António; Lopes, Fernando; Estanqueiro, AnaABSTRACT: The legislation of the European Commission for regulating the European Internal Market of Electricity (EIME) establishes measures for the electricity market harmonization. These measures are designed to encourage the active participation of renewable generation in balancing markets (BMs). RESTrade (Multi-agent Trading of Renewable Production) tool models and enables the simulation of existing secondary and tertiary markets but also simulates improvements to current market designs. These changes, developed within the scope of H2020 TradeRES project (grant agreement no. 864276) are: i) 15-minute trades of reserves and penalty prices, ii) participation of smaller (0.1 MW) aggregated or single players, and iii) separate procurement and bidding of energy and capacity reserves. They are aligned with the EIME legislation. Furthermore, the tool can also compute the imbalance settlement (IS) based on the Portuguese or Spanish mechanisms such as a new approach for computing the dynamic procurement of secondary capacity. This work uses RESTrade to simulate the BMs of Portugal and Spain during 2019, where the weight penalties are around 18.5% and 21.3% of the wholesale market prices. The dynamic procurement increased the usage of its up and down capacities by 12% and 6% in Spain during the period 2019-2022, respectively. The simulation of a new IS mechanism during 2019 in Portugal and Spain, resulted in a reduced penalty of 12.2% and 4.4% of the wholesale prices paid, respectively.
