Public Policies and Investment in the Portuguese Energy Transition
Portugal’s energy transition has been driven by a strategic combination of ambitious public policies aligned with European and international climate commitments. The Portuguese Government has played a central role in defining and implementing measures that accelerate the decarbonisation of the economy, promote energy efficiency, and expand renewable energy sources. Among the most relevant instruments are the revision of the National Energy and Climate Plan 2030 (PNEC 2030) and the investments channelled through the Recovery and Resilience Plan (PRR), which allocate more than €3 billion to climate action. All these efforts share a common goal: ensuring that future generations do not face a devastating scenario.
The PNEC 2030, initially approved in 2019 and later revised in 2023, is the main national strategic framework guiding energy and climate policy until 2030. Its revision was driven by the need to strengthen greenhouse gas (GHG) emission reduction targets, increase the share of renewable energy in final gross consumption, and improve energy efficiency. One of the most significant milestones was the reinforcement of the renewable electricity target, now set at 85% by 2030 — one of the most ambitious levels in the European Union. This goal is reflected, for example, in the expansion of photovoltaic capacity, with projects such as the Alcoutim solar park in the Algarve or the Ourika complex in Évora, which together represent hundreds of megawatts of new clean energy.
In parallel, the PRR — the EU’s post-pandemic funding instrument — has played a transformative role in accelerating the energy transition. Of the €16.6 billion allocated to Portugal, more than €3.2 billion is directly channelled into climate-related measures, covering areas such as sustainable mobility, energy efficiency in buildings, green hydrogen, and modernisation of the electricity grid. One practical example is the “Casa Eficiente 2030” programme, which supports energy refurbishments in homes, offering incentives for installing solar panels, heat pumps, and thermal insulation. By the end of 2023, tens of thousands of families had already benefited, contributing both to emission reductions and to combating energy poverty.
In the mobility sector, the PRR finances the electrification of public transport, including the acquisition of electric buses by municipalities such as Lisbon, Porto and Coimbra, as well as the expansion of the public charging network, which now exceeds 5,000 stations nationwide. Additionally, the “Vales Eficiência” programme supports companies in adopting clean technologies and reducing their carbon footprint, promoting the gradual decarbonisation of the industrial sector.
Another key pillar is investment in green hydrogen, considered essential for hard-to-electrify sectors such as heavy industry and aviation. The “H2Sines” project, located in the industrial complex of Sines, aims to create a renewable hydrogen production hub capable of supplying both the domestic market and exports to the rest of Europe. Co-funded by the PRR and the EU Innovation Fund, this project represents one of the largest green hydrogen investments in the Iberian Peninsula.
The governance of these policies is ensured through interministerial coordination, with the Ministry of Environment and Climate Action and the Ministry of Economy leading implementation. The Portuguese Environment Agency (APA) and the Directorate-General for Energy and Geology (DGEG) play crucial operational roles, ensuring technical oversight and compliance with national targets.
