If we look at the sky and our plains, the country is an undisputed giant. According to official data from the Wind Business Association (AEE)wind energy is already the first source of electricity generation in our country, covering an impressive 24% of national demand. With more than 31,600 megawatts (MW) of accumulated power distributed in 1,412 wind farms, Spain has consolidated itself as the second country in Europe (only behind Germany) and the sixth in the world in installed power.
However, behind this success of “emptied Spain” a broken bridge hides. The wind blows and the blades turn, but we lack the cables to bring that clean energy to the cities and factories where it is actually consumed. And right now, when bureaucracy threatens to suffocate the sector, Europe has just put on the table a report that shows that what we have built to date is just the tip of the iceberg: the margin for growth that Spain has left is not only large, it is overwhelmingly higher than that of the rest of the continent.
An overwhelming first place. The confirmation has come directly from Brussels. The Joint Research Center (JRC) of the European Commission has just published the second edition of the report ENPRESSO 2. This scientific document does not make estimates on the fly: it measures the feasible technical potential of onshore wind energy in Europe with a very high geographical resolution of 1 square kilometer. The results position Spain as the leader of the entire EU by a very wide margin.
As the expert Joaquín Coronado explains:the figures are stratospheric. In the reference scenario, Spain reaches a technical potential of 183.9 gigawatts (GW) of installable capacity and 415.4 TWh/year of generation. More than double that of Romania and Sweden, the next in the ranking. If we cross this with our current capacity, the conclusion is stunning: the ceiling is very far away.
How do we lead with such advantage? The merit of this first place is even greater if we understand how it has been calculated. The European Commission report has applied very strict filters For an area to be considered suitable: the mills cannot be more than 5 kilometers from a road, nor more than 3 kilometers from the electrical grid, and must respect minimum distances from population centers (1 km) and protected areas such as Natura 2000. After passing all these demanding filters, 5.8% of the Spanish territory is available and suitable to house wind turbines.
As Coronado explainsour low relative population density in those areas where it is windier gives us a brutal competitive advantage. We are much less sensitive to changes in separation distances (so-called “setbacks”) than densely populated countries such as Germany, France or Poland. Even if Europe forced us to move 2 kilometers away from towns (the most restrictive scenario), Spain would still retain 52.8 GW of potential.
It’s not all lights. The energy expert warns of a purely internal problem: “regulatory heterogeneity.” While national regulations establish a separation distance of 500 meters for populations, there are autonomous communities such as the Balearic Islands, Navarra or Valencia that require 1,000 meters, and others such as the Basque Country or the Canary Islands that request 400. This regulatory fragmentation means that the real potential varies drastically depending on which side of the autonomous border the wind blows.
The bureaucratic infarction of a “full” network. At this point in the x-ray, it is time to address the elephant in the room. As we have explained in Xatakathe Spanish electrical system suffers a serious administrative “thrombosis”. The network is not physically collapsed, but administratively “full” and underused. Panic broke out when the National Markets and Competition Commission (CNMC) was forced to delay the capacity maps until May because 90% of the nodes appeared in red.
Faced with this bottleneckthe CEO of Red Eléctrica, Roberto García Merino, defends himself by remembering that they have 1.5 billion ready to invest, but the paperwork delays works that barely require a year of physical work for up to a decade. As if the internal traffic jam were not enough, we come across France’s external plug, whose pyrrhic interconnection (2.8%) isolates us and forces us to throw away cheap energy to protect its nuclear industry.
The risk of dying of success. Spain finds itself at a historical crossroads. We have the climate, the soil, the wind and the endorsement of the EU. If we add to this wind potential the 19 GW of reversible hydraulics already in the pipeline, Spain has in its power to develop the most competitive emissions-free electricity mix in all of Europe.
But to achieve that future, heat maps and reports from Brussels are not enough. It is necessary, as experts point out, to homogenize legislation between communities, compensate local populations and, above all, urgently expedite permits to build the network. As a summary from the sector: “The plans are very nice, but they have to be built.”
