Portugal must significantly improve how it monitors electricity production and manages its power grid, according to a new government-commissioned report examining vulnerabilities exposed by a recent blackout.
The findings come from a technical advisory group established by the government about a year ago to anticipate risks and assess weaknesses in the Sistema Elétrico Nacional. The report, released on Monday, outlines a series of recommendations aimed at reinforcing stability, resilience, and responsiveness in the country’s energy infrastructure.
One of the most notable proposals is the creation of a “digital twin” of the Iberian electricity system, a virtual replica designed to simulate real-time conditions and predict potential disruptions. The concept would allow operators to test scenarios, anticipate failures, and respond more effectively to sudden changes in supply or demand.
The advisory group emphasized that maintaining system stability will require stronger dynamic voltage control and faster reaction mechanisms to disturbances. These measures are considered essential in a rapidly evolving energy landscape increasingly shaped by renewable sources.
The report also highlights structural inefficiencies in the planning process. It suggests removing the formal involvement of the Assembleia da República in network planning, arguing that current approval timelines, often delayed by three to four years, result in outdated strategies by the time they are implemented.
To address these challenges, the government led by Luís Montenegro is already reviewing investment priorities. Authorities are focusing on advanced voltage control technologies and streamlining approval processes to accelerate modernization efforts. A comprehensive study on the total costs of the system is also planned.
The transition toward renewable energy has added complexity to grid management. While essential for long-term sustainability, it has introduced greater volatility into electricity markets and increased the risk of instability within the system.
In response, the report calls for stronger coordination at the national level, deeper cooperation across the Iberian Peninsula, and closer alignment with European energy frameworks. It also stresses the importance of clear leadership in managing the transition and ensuring the system remains robust under pressure.
As Portugal continues to shift its energy mix, the report underscores a central message: technological innovation and proactive planning will be critical to preventing future disruptions and ensuring a reliable electricity supply.
