EU Africa power ambition runs into a 1.4 GW bottleneck at Gibraltar
The EU's only electrical link to North Africa carries just 1.4 GW, exposing the gap between Brussels' clean-energy corridor vision and physical infrastructure.
Two 400 kV subsea cables running beneath the Strait of Gibraltar form the European Union's sole electrical connection to the African continent, Montel reported on Monday (2026-07-13). Together they carry 1.4 GW — enough to power a modest industrial cluster, not a continental clean-energy transition.6
The asymmetry in those flows matters. The cables, commissioned in 1997 and 2006, allow 0.9 GW to move southward from Spain into Morocco and just 0.6 GW in the opposite direction. For a corridor that Brussels is positioning as a future artery for North African solar and wind, the infrastructure runs almost entirely the wrong way.6
The European Commission put financial weight behind the broader vision on Tuesday (2026-06-09), pledging €5 billion of EU money toward renewables projects in North Africa and the Middle East, with the explicit aim of feeding electricity back into European grids. Whether that financing materialises into signed agreements is one question. Whether the physical infrastructure can support meaningful northbound flows is a separate one, and the answer to the second is currently no.5
Spain sits at both ends of the calculation. Its domestic renewable buildout has been one of the fastest in Europe. Preliminary data from TSO Red Electrica showed on Monday (2026-05-18) that Spain added roughly 1 GW of new green capacity in April alone — 931 MW of solar and 111 MW of wind.2 Renewables accounted for 70% of total installed power capacity of 138.8 GW by the end of April, with 43,214 MW of solar and 33,443 MW of wind on the grid.2
That buildout has already compressed power prices in Spain well below the European average. Gas-fired plants set the clearing price in 89% of EU power hours so far in 2026, Ember calculates. In Spain, the equivalent figure was 15%.4 A Bank of Spain study found wholesale electricity prices in 2024 were 40% lower than they would have been had the energy mix stayed as it stood in 2019.3 Gas still accounts for around 19% of generation, providing baseload cover when wind and solar falter, but merit-order dynamics on the Iberian Peninsula have shifted structurally.3
Those price signals make Spain a plausible export hub — surplus renewable generation, competitive clearing prices, geographic proximity to North Africa. Morocco in particular has been developing large-scale solar and wind capacity. A functional, high-capacity link would allow flows to run in both directions as conditions dictate: Moroccan solar into Spain during Iberian generation lulls, Spanish surpluses flowing south when supply outpaces local demand.6
The blackout that struck millions of homes and businesses across the Iberian Peninsula — whose anniversary Montel examined in May (2026-05-21) — provides a harder frame. Red Electrica pursued emergency stabilisation measures in the months that followed, and the episode established that interconnection serves both as an export opportunity and as a grid-stability requirement. A high-variable, renewables-heavy grid grows more vulnerable to demand-supply mismatches without the balancing buffer that cross-border flows provide.1
Still, the path from a Commission pledge to functioning cross-Mediterranean cables is long. Projects of this scale typically require a decade to permit, finance and build once political agreements exist. The existing Gibraltar links took decades from initial discussion to commissioning. New lines at meaningful scale would need to traverse deeper water, involve bilateral frameworks between EU member states and sovereign North African governments, and attract private capital alongside whatever Brussels eventually disburses.5
The arithmetic bears stating plainly. If North African solar were to export power to Europe in volumes that materially shifted EU generation balances, flows would need to reach tens of gigawatts. The current total capacity across both existing cables is 1.4 GW, and most of that runs south.6
The €5 billion Commission commitment is the figure to hold against any near-term progress marker — specifically, whether concrete project mandates emerge before 2027 and whether Southern European TSOs begin feasibility studies for additional subsea interconnectors. Without that groundwork, the political framework stays exactly that.5
