Portugal Mandates 72-Hour Energy Autonomy for Critical Infrastructure (eco.sapo.pt)

• New 72-hour energy independence requirement proposed
• Parliamentary investigation into previous blackout
• Strengthening critical infrastructure resilience

"Following the major blackout on April 28 last year, a parliamentary working group has proposed new regulations requiring critical infrastructure operators to maintain at least 72 hours of independent energy autonomy. The initiative seeks to fortify Portugal's resilience against grid failures through mandatory backup power standards."
