- 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.
- Systemic complementarities and transformative change: A tentative methodology to examine bidirectionality effects across connected systems [Resumo]Publication . Padua, Muriela; Fontes, MargaridaABSTRACT: Achieving energy-sustainable goals involves large-scale production and social changes necessary to fulfil societal functions (Geels, 2004; Markard, 2011). These long-term goals imply a transformative change requiring multiple transitions involving multiple socio-technical systems and their interplay (Raven and Verbong, 2007; Geels, 2007; Papachristos, 2013; Rosenbloom, 2020). To fully address system change, it is necessary to consider that changes in one system affect the other (Geels, 2007; Papachristos, 2013), i.e., the presence of bidirectionality in system interactions. However, bidirectionality has only recently started being tackled and remains under-conceptualized.
- Bridging Regional Divides in Decarbonization: Firm Strategies, Policy Tensions, and Structural Trade-offs in Portugal [Resumo]Publication . Vale, Mário; Alves, Tiago; Fontes, Margarida; Mamede, Ricardo; Bento, NunoABSTRACT: The transition to a low-carbon economy is shaped by structural tensions and trade-offs that impact firms, regions, and policymakers. A central challenge is balancing regional equity, industrial specialization, and technological innovation in decarbonization policies (Markard & Rosenbloom, 2022). This study critically examines these tensions by analysing firm-level decarbonization strategies within the Portugal 2020 (PT2020) program, revealing how economic structures shape sustainability transitions and the effectiveness of policy interventions.
- 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.
- Typology of pathways for decarbonization [Resumo]Publication . Bento, Nuno; Alves, Tiago; Ribeiro, Ricardo; Fontes, MargaridaABSTRACT: Addressing the urgent climate change requires a clear knowledge of the options available, as well as an understanding of the possible strategies to reduce carbon emissions. Identifying realistic pathways for decarbonization is crucial to inform agents’ decisions about the relevant measures (Turnheim & Nykvist, 2018), with unawareness of these pathways often delaying climate action (Bergek et al, 2023). This paper seeks to identify, categorize, and analyze decarbonization pathways from the scientific literature, uncovering cross-cutting dimensions, interconnections, and regional trends for enhanced decision-making and accelerated change.
- Design and planning of green supply chains: a fuzzy approachPublication . Pinto, Tânia; Barbosa-Póvoa, Ana Paula; Novais, Augusto Q.Green SC can be seen as logistic structures that guarantee production and global distribution of products in an environmental manner. To achieve this goal companies must invest on the optimal design and planning of their logistic structures, while accounting for the trade-off between profits and environmental impacts. This is addressed using a generic and uniform mathematical framework, the RTN. For this bi-level optimization a SFLP approach is applied, where those objectives are treated as constraints and replaced by a new one, the aspiration level, which embodies a compromise between them.
- Interdisciplinary approach to automated negotiation: a preliminary reportPublication . Lopes, Fernando; Novais, Augusto Q.; Coelho, HelderAutonomous agents with negotiation competence are becoming increasingly important and pervasive. This paper follows an interdisciplinary approach to build autonomous negotiating agents by considering both game-theoretic techniques and bargaining procedures from the social sciences. The paper presents a generic model that handles bilateral multi-issue negotiation, describes equilibrium strategies for the bargaining game of alternating offers, and formalizes important strategies used by human negotiators. Autonomous agents equipped with the model are able to negotiate under both complete and incomplete information, thereby making them very compelling for automated negotiation.
