Traditionally known as a pivotal industrial and maritime hub, Sines is now the site of major infrastructure investments, including large-scale data centers, battery production facilities, hydrogen and green steel plants, and expanded port operations. In parallel, the region is witnessing significant deployment of renewable energy assets, such as solar parks and offshore wind projects, which present a timely opportunity to reimagine its energy system. A USEC presents an innovative approach to energy governance by decentralizing production, promoting local consumption, and integrating renewable energy through smart grid infrastructure. Unlike conventional centralized systems, this model enhances local energy resilience, improves economic circularity, and empowers municipalities to directly influence energy pricing, access, and sustainability outcomes. The closure of the country’s largest coalfired power station in Sines in 2021 has further accelerated the region’s transition toward a cleaner, more distributed energy paradigm. Drawing on the context of Sines, this thesis explores the potential role of municipal leadership in spearheading a USEC. It examines governance models, financing mechanisms, stakeholder engagement strategies, and regulatory barriers. The study also considers broader questions around equitable energy access, long-term affordability, and integration with national and European climate goals. By presenting a structured decision-making framework and highlighting key trade-offs, the case study offers practical insights for policymakers and energy planners seeking to scale utility-scale energy communities in industrialized regions.engmaster thesis204309670
