They are usually lower because they do not include taxes or tolls.

More than 50% of electrical substations are in municipalities with less than 20,000 inhabitants
55.5% of the electrical substations in Spain, that is, 3,387 out of a total of 6,102, are located in municipalities with less than 20,000 inhabitants, which places rural and semi-rural Spain as a key pillar of the energy system. According to an analysis by the Industry and Energy Forum (FIE) together with Opina 360, these territories not only concentrate more than half of the infrastructure, but also play an essential role in industrial development and the energy transition.
The study highlights that this distribution is structural in many provinces, especially in Huesca, Ourense, Soria and Teruel, where the weight of small municipalities exceeds 87%. Even in areas with an urban industrial tradition, such as Guipúzcoa or Vizcaya, the rural presence continues to be decisive, while in large provinces such as Barcelona, Valencia or Seville its relevance continues to be significant.
Furthermore, these municipalities concentrate 58.6% of the available electrical capacity, with 4,335 of the 7,400 MW still unused. This makes them a strategic element for future industrial growth, since, as the director of Opina 360 highlights, they represent a key opportunity for reindustrialization that should be taken into account in energy policies.
