US Grid on ‘Right Track’ to Avoid Incident Similar to Spain’s April Blackout
- On Tuesday, the Spanish government announced a resilience package to strengthen the grid and support renewables, aiming to prevent a repeat of April's blackout.
- Following the April blackout, analysis showed that outdated grid rules, weak voltage control, and poor system coordination triggered the collapse.
- The government report indicates that insufficient voltage control capacity triggered a voltage-driven cascade, causing widespread disconnections across Spain and Portugal on April 28.
- Spain's government announced a resilience package to accelerate voltage control reforms, reduce renewable installation timelines, and support battery storage to prevent future blackouts.
- Beyond immediate reforms, Spain plans to accelerate grid links with France and Portugal, requesting EU market rule waivers to enhance interconnection and regional energy stability.

US grid on ‘right track’ to avoid incident similar to Spain’s April blackout
A widespread blackout like the one that plunged Spain and Portugal into darkness this spring is unlikely to happen in the U.S., according to a leading grid reliability expert. The U.S. electrical grid is better prepared than Spain to handle surges in voltage that caused the blackout. Mark Lauby, senior vice president of the North American Electric Reliability Corp., briefed federal regulators Thursday, June 26, on the April blackout that cut pow…
Spain’s 2025 Blackout and the Real Lessons for Renewable Grids
It was a sunny, unremarkable Monday in April. Demand was low, just 25 GW, well below winter peaks, and wholesale power prices hovered around €18.5/MWh as solar generation surged across the Iberian Peninsula. At first glance, the conditions seemed ideal for a high-renewables day. But behind the scenes, several things were already going wrong. A large number of high-voltage (400 kV) transmission lines in central Spain were offline for maintenance.…
The government, through the royal decree law that has approved with measures to avoid blackouts like the one suffered by the Iberian Peninsula on 28 April, has launched a lifeguard to renewable energy projects that are blocked by judicial resources and precautionary paralysis, something that is especially affecting the new parks in Galicia, where the construction of eight dozen wind installations is on hold; although it also concerns other commu…
The head of Ecological Transition stresses that the historic zero energy of April 28 "should have been avoided" with the regulatory framework then existing and encourages Iberdrola to publish his data: "Transparency is very good"The photovoltaic power plant that is at the origin of the blackout is the megaplant Núñez de Balboa de Iberdrola Secretary of State for Energy since November and former director general of the Institute for Diversificati…
On the next 28 July, the Government will present a package of measures to strengthen the security of the national electricity system following the April 28 package that affected millions of people in Portugal and Spain.
