Iberian Blackout Underscores Urgent Need for Grid Stability — Solar Ireland Supports SolarPower Europe’s Call

Solar Ireland welcomes and supports SolarPower Europe’s clear statement following the Spanish Government’s report on the April 2025 Iberian Blackout. The facts are now confirmed: solar PV was not the cause of the blackout.

This incident underlines an urgent lesson for Ireland and Europe alike: rapidly growing clean energy capacity must be matched with modern, flexible grid infrastructure and enabling policies.

Ireland knows this lesson well. For over two decades, we have tackled the challenges of running a secure, high-renewables power system — through clear operational rules, pioneering stability services and investment in fast-acting storage and synchronous compensators. This forward-thinking approach ensures that more solar can be added safely, affordably, and reliably.

“The Iberian blackout shows we can’t just build renewables — we need smart grids and flexibility to back them up. SolarPower Europe is right to call for urgent investment in grid stability. Ireland’s experience proves it can be done — and must be done.” — Ronan Power, CEO, Solar Ireland

Spain’s experience shows what happens when grid investment lags solar growth. It also shows what’s possible when action is taken: Spain is on track to become a top five European battery market this year. Ireland must also act decisively to close the gap between solar deployment and system flexibility.

Solar remains Ireland’s and Europe’s strongest technology for affordable, secure energy. Let’s ensure our grids are ready to make the most of it.
