In 2024 alone, 1.7 TWh of renewable energy was curtailed—a 13% increase from 2023. Meanwhile, congestion management costs have surged, from an annual average of €390M (2017–2020) to €1.7B in 2023, and up to €2.5B in 2024, adding financial strain to market participants.
Curtailment remains highly concentrated: just 15 provinces, including Badajoz, Zaragoza, and La Coruña, accounted for 81% of all curtailment in the past three years. With hydrogen expansion and rapid wind buildout, these risks will continue to escalate unless properly addressed. Even with planned grid reinforcements, transmission constraints persist as renewable capacity grows faster than infrastructure upgrades.
