While the Iberian Peninsula registers a surplus of unprecedented renewable energy at bargain prices, the rest of the continent continues to be suffocated by triple-digit bills. In the middle of these two realities a wall rises, not of stone, but of political and nuclear interests: France. The northern neighbor acts as a plug that prevents cheap energy from the south from flowing north, protecting its atomic industry at the expense of European consumers’ pockets.
Two Europes disconnected. The data from February 11 are a blow to the table of European integration. According to the records of OMIE and ESIOSthe average daily market price in Spain has plummeted to €4.23/MWh, with hours in which producers have had to pay for injecting energy (negative prices of -€0.42/MWh). The situation in Portugal is even more extreme: the megawatt hour is paid at €0.34, that is, practically free.
However, it is enough to cross the Pyrenees for reality to change drastically. The price map ESIOS turns central and northern Europe red: Germany pays electricity at €100.62/MWh, Belgium at €72.04/MWh and the Netherlands at €88.70/MWh. France, strategically located in the middle, enjoys a comfortable price of €13.61/MWh, benefiting from buying cheaply from the south without missing out on the flow to its northern neighbors. This disparity perfectly visualizes the concept of “energy island”: a peninsula overflowing with resources that does not have enough bridges to share them.
The great uncoupling of February. What we are experiencing these first two weeks of February is what experts call a “total decoupling.” According to the analysis of Aleasoft Energy Forecastingthe arrival of several Atlantic storms has triggered wind and hydroelectric generation on the peninsula. By adding the solar contribution, the supply has far exceeded the internal demand.
The Iberian market (MIBEL) has seen how their prices They fell by 43% in Spain and a staggering 74% in Portugal in just one week, reaching daily averages of €0.54/MWh, values that had not been seen since April 2024. Meanwhile, the Energy Charts graphs show that Germany has continued with prices oscillating above €100/MWh for much of January and early February, still depending on non-renewable sources.
The drama of throwing away energy. Having cheap electricity seems like excellent news for the domestic consumer, but it hides a serious systemic inefficiency. As there are not enough cables to export this surplus to a Europe thirsty for cheap energy, Spain is forced to carry out curtailment (technical discharges). As we have already explained in Xatakawe are literally throwing away around 7% of clean energy because it “does not fit” into the grid and has no outlet.
This scenario causes zero prices that, paradoxically, can ruin renewable investors, who need profitability to continue deploying parks. Furthermore, the situation has uncovered the seams of the Spanish internal network. The network is administratively “collapsed”: the CNMC has had to delay until May 2026 the publication of the capacity maps because, under the new security criteria, 90% of the network nodes appear saturated. Only 12% of connection requests are being approved, which means that we have the energy, but the cables are missing to bring it to new industries and homes.
The French nuclear “bunker”. If there is excess energy in the south and lack in the north, why not build an electric highway? The answer has its own name: nuclear protectionism. President Emmanuel Macron has declared that interconnections They are a “false debate”arguing that Spain’s problem is a “100% renewable model that its own network does not support.” However, the data refute the Elysée story. As expert Joaquín Coronado explainsSpain is not 100% renewable (it closed 2025 at 55.5%) and, in fact, it was Spain that came to the rescue of France in 2022 and 2025, exporting electricity through its combined cycles when the French nuclear park failed due to corrosion and heat problems.
The reality, according to the CEO of RedeiaRoberto García Merino, is that the blockade “is not technical, it is pure geostrategy.” France needs to make profitable a pharaonic investment of 300,000 million euros in its nuclear park and fears that the massive entry of Spanish solar energy, much cheaper, will sink the prices and competitiveness of its reactors. Therefore, Paris has explicitly excluded of its 2025-2035 network plan the key interconnection projects for Aragon and Navarra, keeping the Iberian Peninsula as an island with only 2.8% interconnection, very far from the European objective of 15%.
Any solution on the table? Brussels’ patience is running out. The European Commission has already issued an ultimatum to Francegiving him a period of nine months to unblock the situation and present a political declaration of commitment.
Meanwhile, the only project that advancesalthough slow, is the submarine cable through the Bay of Biscay. Redeia confirmed that the laying campaigns will begin this summer of 2026, with an eye on its entry into operation by 2028.
An unsustainable contradiction. Within the European Union, it is happening that while one member country desperately seeks energy autonomy and competitive prices for its industry, it allows another of its key partners to keep the door to the south closed. Spain could be Europe’s green battery, but without export capacity, that wealth is diluted in negative prices and technical waste. Everything happens while France acts as a strict customs officer that protects its atoms, preventing the European Union from truly being an energy union.
