An analysis of the incidence of negative prices in the electricity market and the strategies for the sector’s adaptation.
In a surprising turn for the European energy market, especially in Spain, negative prices in the wholesale electricity market became a constant during April, setting a record in the sector’s history. This phenomenon, which might seem beneficial for consumers at first glance, poses significant and strategic challenges for energy operators and generators.
This situation seems unthinkable: the month of April had an average of €13.67/MWh, whereas a year ago, in 2023, the average was €73.73/MWh and in 2022 it reached a peak of €191.52/MWh.
It is clear that the change in the sector is profound: a structural change is taking place in the energy system, along with an increase in efficiency.
Since the beginning of April, the electricity market has experienced days with negative prices for an unprecedented number of hours. According to data from the Iberian Energy Market Operator (OMIE), for almost half the time prices ranged between zero and negative, a situation that combines demand that has not yet recovered with high supply due to the strong output of renewable sources such as hydroelectric, wind and solar power.
Although negative prices reduce costs for consumers, they can create problems for producers, especially those that depend on sources with higher operating costs.
It will be decisive for renewable energy generation companies whether they have done their homework well and have good planning in place so as not to be affected by this situation, since we know that this sector is a long-term one, a long-distance race.
What we are currently seeing is that supply does not stop and continues to pour energy into the grid, even though prices are negative and demand is not rising. Does this mean there is an oversupply? Investments in renewable energy installations are under way; it is not a type of industry that can be brought to a sudden halt, it is slow, an installation is not achieved in the short term, and more renewable energy will be added to the energy mix in the coming years. So what will happen with so much surplus energy?
Spain has an opportunity to position itself as a generator of energy at a good price, below our European competitors, and this situation, well planned, may be what we need in Spain to shift from a production model based on the services sector (tourism) to a more balanced one with the industrial sector, which generates stable and more qualified employment.
The unexpected increase in hydroelectric power has been a surprise that has thrown off the energy generation mix, and it also seems that everything invested in self-consumption, by both companies and individuals, is taking effect, along with the awareness of the need to implement energy savings: we have become much more conscious of the need to save.
In response, experts suggest that companies should diversify their sources of income, improve operational efficiency and increase the flexibility of their operations to handle price volatility.
In a recent round table on the El Periódico de la Energía video podcast, Javier Revuelta of AFRY, together with other experts, discussed the long-term implications of this phenomenon and the strategies needed to adapt to this new energy environment. Revuelta stressed the need to integrate energy storage solutions, a crucial point, and to take part in adjustment and balancing services markets, advocating continued investment in renewable energy.
Another crucial point is the distribution network, which is a fundamental part of the entire electricity system. Recently the CEO of Endesa, José Bogas, called for an “improvement and updating” of its regulation, having warned that the “bottlenecks” in the electricity grid have prevented the company from connecting a total of 15 gigawatts (GW) of demand over the last four years; this figure, as regards Endesa, if extrapolated to national level, could amount to 30 GW, which means a large number of gigawatts of lost demand representing missed opportunities for economic growth, investments in data centres, new industries, charging points or the expansion of current industrial facilities.
As Europe advances towards a more sustainable future, continuous observation and adaptation will be crucial for all players in the energy sector. Negative prices are an indicator of the profound transformations of the market, offering challenges and opportunities to innovate and develop new technologies and business models.

The sector faces a transformation that requires rapid and efficient adaptation. It is essential that public policies and corporate strategies are aligned to ensure the stability and sustainability of the energy market in this new paradigm; ideally, the country’s two main political parties would have a clear view of this and cooperate, because the country’s sustained and balanced growth depends on it.
Adapting to these changes is not only necessary for the economic viability of the sector’s companies, but also crucial to achieving long-term sustainability and carbon emission reduction targets.
It is a path full of challenges that can help us become a leading country.
