KEY POINTS
- Portugal’s government says its return to REN, via a 13.7% stake rising toward 20%, will not affect China State Grid’s 25% holding, which it wants to keep.
- The state exited REN 12 years ago during Portugal’s bailout, the period when State Grid became the operator’s largest shareholder.
- The Finance Ministry framed the investment as strategic, citing energy security, the transition and the electrification tied to AI and data centres.
Portugal’s government said its move to buy a stake in power and gas grid operator REN will have no bearing on the 25% holding of China’s State Grid, which Lisbon wants to keep on board as a key shareholder.
The state agreed last month to acquire 13.7% of REN, returning 12 years after it exited during Portugal’s bailout. Notably, that crisis-era retreat opened the door for the Chinese state-owned utility to take a 25% stake and become REN’s largest shareholder. Moreover, the government now plans to lift its own holding to as much as 20%.
Reassurance for Beijing
Lisbon moved quickly to calm any concern in China. According to the Finance Ministry, the government told Beijing that the state’s entry into REN would not change State Grid’s 25% position. Furthermore, it said the opposite is true, stressing that “it is in the Portuguese government’s interest for State Grid to remain a reference shareholder in REN.”
The ministry cast the investment as strategic rather than defensive. Specifically, it pointed to rising geopolitical uncertainty and the growing importance of energy infrastructure, arguing that electricity and gas networks underpin energy security, the transition and industrial growth.
Part of a wider trend
Portugal framed the step as catching up with its neighbors. Additionally, the ministry noted the country had been the only European Union member without a state stake in its national electricity grid operator, while most EU peers retain state ownership or significant shareholdings. Consequently, officials argued the move aligns Portugal with a broader shift toward government involvement in strategic sectors.
The AI angle featured prominently too. Meanwhile, the ministry said the push to electrify the economy and attract investment in artificial intelligence and data centres strengthened the case. Ultimately, Lisbon wants greater oversight of a critical asset while signaling to Beijing that its long-standing partner remains welcome.
