Our distribution grid
On this page, we explain how our electricity distribution network works and how we bring electricity to your home or business.
Where do we operate?
At e‑distribución, we operate in:
- 24 Spanish provinces.
- 8 autonomous communities: Andalucía, Aragón, Baleares, Canarias, Cataluña, Extremadura, Castilla y León, and Galicia.
- Ciudad Autónoma de Ceuta.
Our network supplies nearly 21 million people.
Main components of the distribution network
Our distribution network consists of the following elements:
Electrical substations
- They transform high-voltage electricity into medium voltage, allowing it to be distributed to consumers.
- They are usually located near generation plants or on the outskirts of cities.
Transformer substations
They convert medium voltage into low voltage, which is necessary to supply electricity to homes, shops, and businesses.
Power lines
They transmitenergy from substations to consumption points.
They can be high, medium, or low-voltage lines, depending on the amount of energy they transport.
Metering equipment
They record electricity consumption at each supply point.
- Meters are usually located outside the home or business.
- Smart meters send information through the electricity grid itself using PLC (Power Line Communications) technology.
- Data is collected at the transformer substations and reaches our systems remotely.
