Invoice

At first glance it seems a contradiction: we produce more solar and wind energy than ever, and yet The invoice continues. Sometimes it seems that everything returns to the same thing: gas. And, in part, it is true. The gas continues to enter every night to sustain the electrical system when the sun falls. But behind that reality there is another less visible: Spain is getting the structural link between electricity and fossil fuels. Reducing the power of gas. According to an Ember analysisthe influence of gas and coal in electric prices has been reduced by 75% since 2019. In the first half of 2025, the gas only determined the price of light 19% of the time, compared to 75% of six years ago. The result is overwhelming: the wholesale price of electricity in Spain was 32 % lower than the European average. While Germany or Italy have barely reduced the influence of gas by 12%and 13%, respectively, Spain has done it in 75%. It is a much faster jump than in any other large European electric market. Spain stopped the power of gas and coal, becoming one of the cheapest markets in Europe This fall reflects a deep transformation of the system. The country has made renewable energy – more cheap and stable – progressively replace gas and coal in pricing. So why don’t you notice the invoice? The answer, as we will see, has to do with the network, the storage and a blackout that changed the rules of the game. An exponential growth. Since 2019, Spain added more than 40 GW Of new wind and solar capacity, which has allowed the renewables to cover 46 % of the electrical demand in the first half of 2025. In that same period, the generation with gas and coal fell to 20 %, compared to more than 40 % that still register Germany and Italy. This transformation has had a direct effect on the market: gas and coal are barely marked the price of light. “Spain has broken the dire bond between electricity and fossil fuels”, summarize Chris RossloweEmber analyst. However, this technical achievement does not mean that the system is free of shadows. The imperceptible success. Here comes the less encouraging part. The problem is not only how much it costs to generate electricity, but how the system remains stable. After the blackout of April 28, 2025, Ree adopted an “reinforced” operational modeactivating more combined gas cycles to stabilize the network. That strategy avoided new cuts, but had a high cost. The use of gas for network services – as voltage control or frequency regulation – doubled in May 2025 compared to the previous year. These services went from representing 14% of the final price before the blackout at 57% that month, According to Ember. In addition, the missing renewable energy (Curtailment) It tripled after the blackout, moving from 1.8% in the two years prior to 7.2% between May and July 2025. In practice, a part of the clean energy generated is lost because the system cannot manage it. A power with bottlenecks. Despite being a renewable power, Spain only invests 30 cents in electrical networks for each euro allocated to renewables, compared to the 70 cents on average in Europe, As the report explains. And although it is the fourth largest electrical market of the continent, it occupies the 13th position in battery capacity, with just 120 MW installed. In some points of the network, Ree has recognized losses of up to 30% of the renewable generation due to lack of infrastructure. This imbalance prevents the clean energy from fully taking advantage of and forces to resort to gas as support. As we have pointed out in Xatakathe system is still vulnerable and rigid: only one in ten new facilities manages to access the network. After the blackout. The blackout marked a before and after. Although European experts have published A factual report, the official report is not expected until the end of the year. Following that episode, the government approved Royal Decree-Law 7/2025with measures to reinforce the network, encourage storage and make access to hybrid facilities. Although the text was rejected by Congress on July 22, part of its measures are being applied by other ways. Among them, As Ember points outthe incorporation of eight synchronous compensators – devices that stabilize the tension without using fossil fuels – and the impulse of 2,600 MW of new batteries, of which 340 MW already have permission. The Executive also plans to launch capacity auctions before 2026 to keep gas plants operational while structural solutions are displayed. But the message of the sector is clear: it will take time, investment and brave political decisions. The European Energy Laboratory. The Spanish case has become a mirror for the rest of the continent. It has shown that growing in solar and wind reduces the wholesale price and gas dependence, but also that without network and storage investment the benefits do not reach the consumer. In Brussels and in neighboring markets, Spain’s example is closely followed as a transition model: a country that has reduced its fossil dependence without sacrificing competitiveness, but still fights to transfer that advantage to the citizen. In Rosslowe’s words: “Spain has shown the way, but to keep it you need to invest in clean flexibility and modern networks.” Electricity is already cheaper to produce. It is also necessary to pay.
