WattSwap is a Luxembourg start-up that organises energy sharing between neighbours: people who produce solar electricity sell it to people who consume it, at a better price than on the grid.
Who they are
- Luxembourg start-up founded by Tom and Pierre, based in Roodt-sur-Syre
- What they do: they connect you to an energy community and handle the paperwork
- No works: sharing runs through the smart meter you already have
- No change of supplier: your current contract takes over when solar power is not enough
- Their fees: 1.5 cents per kWh, no installation fee and no fixed cost
Why we work with them
trigger helps you cut your spending in Luxembourg. Energy sharing is part of that, but you need to join an energy community: WattSwap does it for you.
When you leave us your details about energy sharing, your request is passed on to WattSwap. trigger articles are still written and checked by the trigger team.
