Generate your renewable energy with Spain’s natural resources (sun, wind and hydro) and use it wherever you choose.
Tap your country on the map (or choose your continent first). We’ll show you what you can do from there and take you to the website in your language.
Every country in blue can purchase. Dark blue ones have the website and videos in their own language; the rest, in the closest language (English, Spanish, French…).
You live between your country and Spain. Your energy can too.
An energy nomad is someone who splits their life between two countries —their usual home and their home in Spain— and wants to take advantage of the Spanish sun wherever they are: they generate renewable energy here, offset it on their bill and take the savings with them.
- Retirees and families with a second home on the Mediterranean coast or in the Canary Islands.
- People who spend the winter in Spain and the summer in their own country (or the other way round).
- People who want to help their family in Spain by paying their electricity from abroad.
Energy produced per year by 1 kWp of solar panels (kWh, approx.)
The same panel in the Canary Islands produces about 1.8 times as much as in London or Berlin. Indicative values.
Digital nomad, energy nomad… or both
💻 Digital nomad
A digital nomad works remotely thanks to the internet and lives on the move: a few months in one country, a few months in another.
Be free. No long queues, no waiting and no abusive rates at exchange offices.
- Move around the world with a single card and a single currency.
- Top up from wherever you are and pay in local currency.
- With sustainable impact: your card is topped up with renewable energy generated in Spain.
- You don’t need a home in Spain.
☀️ Energy nomad
You live between your country and Spain. The Spanish sun generates your energy and turns it into balance for your card.
- You generate renewable energy in Spain.
- It offsets your bill or becomes VOLT.
- You spend that balance in any country, in local currency.
An energy nomad can also be a digital nomad: the two add up.
Do you have a supply point (CUPS) in Spain?
Yes, I have a home in Spain
- Acquire rights to renewable energy with the “Match 96” tariff.
- Your generation is offset against your consumption, quarter-hour by quarter-hour.
- You receive the surplus as VOLT cashback on your card.
No, I live outside Spain
- Renewable energy participations for residents of any country.
- Make your free, no-commitment reservation: you join the waiting list.
- The more KWPN (nominal peak kilowatts: power capacity with acquired energy rights) you reserve, the sooner your turn comes. We’ll let you know when capacity is available.
