Portugal: An Energy & Natural Resources Overview
Portugal’s energy sector is undergoing a significant transformation, driven by ambitious renewable energy targets under the National Energy and Climate Plan for 2030 (reaching 51% renewable energy in final energy consumption by 2030).
In this context, Portugal continues to position itself as a leader in the energy transition, with a strong focus on decarbonisation, innovation and sustainability. However, legal complexities and economic and infrastructure challenges pose both opportunities and hurdles for stakeholders, who must navigate certain constraints.
In fact, despite the consistent renewable energy policies and the successful phase-out of coal-fired power plants in 2021, Portugal faces challenges related to public opposition to large-scale solar projects, increasing grid congestion, and the need to accelerate decarbonisation in sectors such as industry and transportation.
At the same time, the current international geopolitical context has heightened concerns over energy security, price volatility and reliance on imported fossil fuels. This environment reinforces the strategic importance of domestic renewable generation, grid resilience and energy independence, creating additional investment opportunities.
Portugal is also well positioned to benefit from the development of renewable‑powered data centres, supported by its high share of renewables, competitive electricity prices and role as a digital connectivity hub.
The expansion of energy‑intensive infrastructure, combined with EU‑level efforts to reduce exposure to geopolitical shocks, is increasing the need for substantial investment in electricity networks, including grid reinforcement, interconnections, storage and flexibility solutions. Further opportunities arise in grid modernisation, electrification of transport and industrial decarbonisation, aligning Portugal with broader European energy security and climate objectives.
Economic Conditions and Investment Trends
Portugal’s economy in 2026 continues to demonstrate resilience, with moderate GDP growth and sustained investment in strategic sectors. Portugal continues to present a compelling environment for renewable energy investment and to strengthen its role as a key energy gateway within Europe, underpinned by a strategic geographic location with expanding interconnection capacity with Spain and the broader European network, significant offshore wind potential, increasing demand from energy-intensive sectors, and a supportive policy landscape.
Regulatory and Legislative Developments
The legal and regulatory framework governing the Portuguese energy sector, which is set out in Decree‑Law No 15/2022, has been subject to successive amendments aimed at aligning national law with EU energy policies and the objectives of the European Green Deal. Amendments adopted in December 2024 sought to streamline licensing procedures for renewable energy projects and partially transpose Directive (EU) 2023/2413 of the European Parliament and of the Council of 18 October 2023 (the “RED III Directive”), while maintaining the overall structure of the National Electricity System.The Portuguese government has continued to work to address administrative bottlenecks and uncertainties in renewable energy projects permitting processes, notably by extending the exceptional administrative simplification measures for renewable energy projects licensing to 31 December 2026.
Following the Iberian blackout of 28 April 2025, the government presented a System Security Reinforcement Plan comprising a package of measures with an overall budget of approximately EUR400 million, aimed at strengthening the resilience and operational security of the National Electricity System. Within this broader framework, which includes investment in network operation and control, adjustments to grid access mechanisms and accelerated licensing procedures, battery energy storage systems (BESS) have been identified as a key flexibility and system‑security resource. In this context, in addition to the ongoing implementation of a public funding scheme launched in 2024 supporting around 500 MW of energy storage capacity, a dedicated competitive procedure to remunerate the provision of system services by battery storage has been announced as part of the same resilience package, although it has not yet been formally launched. Recently, the government announced the allocation of EUR60.25 million under the Recovery and Resilience Plan (PRR) to support the installation of battery storage systems directly connected to the public grid, through non‑refundable grants covering up to 20% of eligible costs.
In addition, the government has adopted measures that allow BESS to access grid injection capacity previously reserved for renewable energy generation projects, improving the framework for integrating storage solutions alongside renewable generation.
In February 2025, the results of the first centralised auction for green hydrogen and biomethane (held in 2024) were published and, in May 2025, Decree‑Law No 79/2025 was published, which amends the National Gas System regime to integrate renewable and low‑carbon gases, including hydrogen, into the legal framework. The law expands the definition of gas to cover renewable gases, introduces legal recognition of renewable hydrogen, updates infrastructure provisions, and designates the authorities responsible for licensing and regulation, thereby strengthening the institutional basis for renewable gas markets.
Regarding the Iberian Electricity Market (MIBEL), the applicable regulatory framework has continued to evolve to accommodate higher shares of renewable generation and increased flexibility needs. Recent adjustments include changes to market design and system operation, notably the progressive alignment with a 15‑minute market and settlement interval, affecting intraday trading, imbalance settlement and system services.
In parallel, regulatory and policy initiatives addressing energy‑intensive infrastructure, notably data centres, have gained prominence. A national strategy specifically addressing data‑intensive digital infrastructure has been adopted, reflecting a co-ordinated approach that links energy regulation, grid planning, licensing procedures and industrial policy. This framework recognises the relevance of data centres and provides for simplified permitting regimes, the identification of pre‑approved zones with infrastructure readiness and co-ordinated engagement with public authorities. These measures are intended to ensure that the development of such infrastructure is aligned with network capacity, energy policy objectives and sustainability considerations.
Challenges and Potential Hurdles
While Portugal offers a promising environment for renewable energy development, several challenges remain.
Grid congestion in certain regions resulting from the rapid expansion of renewable energy capacity remains a relevant constraint and access to the electricity network has therefore become a central consideration in project planning, with implications for both timelines and site selection.
Licensing and permitting procedures, while subject to ongoing simplification efforts, remain complex, particularly where multiple authorities are involved. Co-ordination between energy, environmental, planning and municipal bodies continues to require careful management and can, in certain cases, extend administrative timelines. Environmental constraints, land‑use restrictions and the need to address local stakeholder concerns also remain relevant elements of the licensing process.
Overall, these challenges reflect the complexity of balancing renewable deployment, increasing demand and system stability within an evolving regulatory framework, rather than indicating structural barriers to sector development.
Opportunities and Strategic Considerations
Within the existing legal and regulatory framework, companies operating in the Portuguese energy sector are required to adopt a structured and proactive regulatory compliance approach. Familiarity with the National Electricity System framework, licensing requirements under Decree‑Law No 15/2022 and grid access rules is essential for effective project development and transaction planning.
From a strategic perspective, early engagement with grid operators and licensing authorities, careful assessment of connection capacity and proactive management of permitting processes are increasingly relevant. Energy storage solutions, including battery storage, are also gaining relevance from a regulatory and system‑integration standpoint, particularly in relation to flexibility and congestion management.
More broadly, the increasing co-ordination between energy regulation, infrastructure planning and sector‑specific policy initiatives (including those applicable to data‑intensive installations) is shaping the current regulatory environment.
