Although there is overlap, especially in border areas, the electricity distribution companies cover the following areas:
- e-distribución: Catalonia, Aragón, Andalusia, Balearic Islands, Canary Islands and the province of Badajoz.
- i-DE: Basque Country, Navarre, La Rioja, Castile and León except the province of Segovia and the west of province of León, Madrid except the south of the Autonomous Community, the province of Cáceres, west of the province of Toledo, north of the province of Guadalajara, the Valencian Community and Murcia.
- UFD: Galicia, the west of the province of León, the province of Segovia, the south of the Autonomous Community of Madrid, the province of Ciudad Real, the province of Cuenca, most of the province of Toledo and the south of the province of Guadalajara.
- E-REDES: Asturias.
- Viesgo Distribución: Cantabria and some parts of southern and western Asturias.
Your distributor will charge you:
- Around 11 euros for reducing service capacity, irrespective of the size of the decrease. After the alteration, you’ll be sent a bill for “connection charges”.
- Approximately 45 euros for each kW you increase service capacity. After the alteration, you’ll be sent a bill for “access and extension charges”.
- Depending on your distributor, you may be charged for other concepts or be required to provide a deposit.
Be careful! Sometimes what appears to be cheap at first ends up costing a lot. If you reduce service capacity by too much, you might not have enough (your circuit breaker may trip when you turn on several appliances at the same time). You’ll have to increase it again and will pay quite a bit more than you had expected. Distributors are also only obliged to alter your service capacity once a year, so you may encounter problems if you need to make more changes.
You may also have to pay for a new Electrical Installation Certificate on top of all these charges ( which costs 50-200 euros).
What is the certificate and how much does it cost?
It’s a document that certifies your supply is in working order. In this section, we explain why the Electrical Installation Certificate (CIE) is so important.
Your distributor requires one in the following circumstances:
- More than 20 years have elapsed since the last one was issued.
- The service capacity you have contracted is higher than that stipulated on your certificate.
- If you have made a change in the electrical voltage.
- You ask for the service capacity to be changed for a new property that has never been lived in.
- You live in the Canary Islands and want to alter service capacity.
You’ll need to call an approved technician to get a new certificate: charges vary a lot (50-200 euros), so we recommend asking for several quotes.
What you can save by reducing service capacity
Decreasing your service capacity will have an immediate effect on your bill, and will continue to do so because it means reducing a fixed charge.
For an average home, you’ll save around 5 euros a month or 60 euros per annum for each service capacity band you drop down to.
