Why do Spain and Portugal remain isolated from the European Grid?Spain and Portugal stay rather isolated from the main European grid despite attempts to enhance cross-border connectivity, with an interconnection level of only approximately 6% of capacity—far below the European Union’s minimum goal of 10% and the optimal resilience threshold of 15%.
What's going on with Portugal's electricity system after a blackout?(AP Photo/Armando Franca, file) LISBON (AP) — Portuguese authorities on Monday announced a raft of measures to strengthen the country’s electricity system following the April 28 blackout that left most of Spain and Portugal without power for several hours.
How did the black start power stations help Portugal recover from a blackout?The black start power stations helped Portugal restore its power independently from Spain after the blackout. Authorities said they would spend 25 million euros ($29 million) to reinforce back-up energy sources such as solar panels and batteries at hospitals and other critical infrastructure.
How did Spain's power outage affect Portugal?The outage began shortly after noon on April 28 in Spain and lasted through nightfall, disrupting businesses, transit systems, cellular networks, internet connectivity and other critical infrastructure. Spain lost 15 gigawatts of electricity — or about 60% of its supply. Portugal, whose grid is connected to Spain’s, also went down.
How did Portugal restore power after the April blackout?Spain’s interconnections with Morocco and France were critical to restoring power after the April blackout. Portuguese authorities said they would increase the number of power stations with autonomous restart capability from two to four. The black start power stations helped Portugal restore its power independently from Spain after the blackout.
How do grid-following inverters work?Traditional “grid-following” inverters require an outside signal from the electrical grid to determine when the switching will occur in order to produce a sine wave that can be injected into the power grid. In these systems, the power from the grid provides a signal that the inverter tries to mat
