The announcement, made by Environment and Energy Minister Maria da Graça Carvalho, highlights the country’s commitment to resilience, sustainability, and long-term infrastructure strength.
Speaking before the Environment and Energy Committee, the minister outlined a comprehensive strategy designed to modernise both the transmission and distribution networks.
Of the proposed investment, €3.04 billion is earmarked for distribution systems, ensuring efficient delivery of electricity to homes and businesses, while €497 million will support core transmission projects.
A further €775 million is allocated to complementary initiatives, alongside €133 million already approved for urgent upgrades.
This ambitious programme follows the nationwide blackout of April 2025 and reflects Portugal’s proactive response.
Rather than simply reacting, the government is taking decisive steps to reduce the likelihood of future disruptions while ensuring faster recovery times should they occur.
As the minister noted, while no country can entirely eliminate such risks, Portugal is determined to remain among the best prepared.
Key measures extend beyond grid reinforcement. The government has introduced a package of 31 initiatives, including €137 million dedicated to improving grid operation and control systems.

In parallel, energy storage is receiving a significant boost, with €180 million from the Recovery and Resilience Plan allocated to battery projects, an essential component in stabilising renewable energy supply.
Innovation also plays a central role. Pilot projects worth €25 million will explore battery storage combined with renewable energy for self-consumption in critical infrastructure such as hospitals, care homes, and emergency services.
This ensures that essential facilities maintain autonomy even during system stress.
Additionally, Portugal has strengthened its “blackstart” capability.
These are systems that allow power plants to restart independently after a shutdown.
By maintaining four such facilities instead of two, the country significantly enhances its ability to recover quickly from outages.
Taken together, these measures position Portugal as a resilient, modern, and investment-ready economy. Its commitment to clean energy, infrastructure development, and technological innovation continues to attract international attention.
For investors seeking stable, forward-looking opportunities within Europe’s energy transition, Portugal offers a compelling landscape.
