• Claiming that “there is no industry that has been unable to connect due to a lack of Red Eléctrica infrastructure” is inaccurate.

  • In five months, Andalusia has lost 921 MW of available electrical capacity, more than the entire capacity currently in its grid (630 MW).

  • The problem is not saturation itself, but saturation without expansion: when the grid is full, but not reinforced to accompany demand growth.

Dear Ms. Corredor,

I am writing to you as president of the Foro Industria y Energía after reading your statements published a few days ago in OK Diario. I should begin by saying that I have no doubt about the professionalism and expertise of the people working in the company you lead. I also do not doubt that, although REE and Redeia are making significant efforts to solve the problem of grid access, a very large part of the responsibility is administrative and therefore falls under the public administration.

Your position, so clearly defined, only confirms that the problem does indeed exist and, therefore, stating—as you do—that “there is no industry that has been unable to connect due to a lack of Red Eléctrica infrastructure” is inaccurate. In fact, at the Foro Industria y Energía we are aware of companies that have even had to renounce PERTE funding because they lacked that possibility. You are probably unaware of these difficulties because those companies have preferred not to make the situation public, we understand, among other reasons, out of institutional respect.

Others, however, have not hesitated to do so, even if it has gone largely unnoticed by public opinion. A few weeks ago, for example, we published on our website an article on how access to the electricity grid is putting a ceiling on Asturian industry, which included statements by the president of Asturiana de Zinc, Carlos Navalpotro, stating that “there are industries that want to decarbonise and cannot because they do not have access to the grid.”

Believe me, Ms. Corredor. The ostrich technique—hiding one’s head and denying the evidence—will not solve the problems. For this reason, I would like to invite you to visit our Map of demand capacity by electrical substations, which we have developed jointly with Opina360, where you can check the availability of more than 6,000 electricity distribution substations and confirm that the trend is truly worrying: there is ever less access, and the available capacity is not necessarily located where industry needs it, despite being the main consumer of electricity in our country.

Allow me to give you an example: if you analyse substation availability in the province of Barcelona, the data may appear positive, since in gross terms there is 30% availability. However, if we look at each substation individually, you can see that a very significant portion of the available capacity is located in the centre of Barcelona, where, as is obvious, large industries are no longer located. Substations such as Maragall or Vilanova, located in areas that were once industrial but are now fully urban centres, alone concentrate almost 100 GW of the just over 800 available in the province. They have capacity available, but it is impossible for an industrial company to be located there today. And it will be difficult to consume it through the washing machines and air conditioners of the citizens who now live there. These are facilities designed for the industry of the 20th century, but poorly adapted to the real needs of the 21st century.

The situation in Andalusia is also particularly concerning. In five months, Andalusia has lost 921 MW of available electrical capacity, more than the entire capacity currently in its grid (630 MW). This figure, in itself, is not necessarily negative. On the contrary: available capacity is meant to be used, and excessive capacity growth is not good news either, because it likely means that industries are shutting down and therefore abandoning their activity. A saturated substation is not, in itself, a problem, but a sign that productive activity is making use of the available grid capacity. The problem is not saturation itself, but saturation without expansion: when the grid fills up but is not reinforced to accompany demand growth.

What is truly serious is that the capacities being accessed are not being expanded and, therefore, a point will come when they run out. In the case of Andalusia, if the current pace continues, the grid could run out of margin in the coming months because electricity connection infrastructure is not growing at the pace industry requires, and this has direct consequences for the ability to attract industrial investment.

As the person responsible for the transmission grid, you also cannot hide behind the argument that saturation is a distribution companies’ problem. Red Eléctrica’s own data from June shows that at least 42% of transmission substations (394 out of 937) do not have available access capacity for demand. And one third (313) have unknown availability due to a lack of agreement on the reference value, meaning they can also be considered blocked. As a result, only one in four transmission substations (24.5%) has capacity for demand.

In light of this situation, a medium-term vision is necessary. Even accepting your claim that no company has been “disconnected”—which, as I have said, is not true—the situation is worrying, because even if it has not happened yet, it will certainly happen if the necessary measures are not taken now. Industry cares little about who is responsible. And the best advice we can give is to apply the slogan of the famous sports brand: Just do it.
