A solar panel owner sells surplus electricity back to the grid at 5 cents per kWh. Their neighbor buys from that same grid at 20 cents. The 15-cent spread goes to the grid operator — even though the energy doesn't physically move anywhere.
EU Directive 2024/1711 mandates energy sharing in all member states by July 2026. European Commission estimates €500–1,100/year savings per household.
Collective self-consumption law (ACC, DL 15/2022) lets neighbors form an energy group and trade directly — with reduced network tariff (CIEG exempt for 7 years). The producer earns 60% more than grid feed-in, the neighbor pays 47% less. Parahub acts as EGAC and handles DGEG registration.
If you have solar panels
- 1Connect your inverter to Parahub — once, at installation
- 2Parahub automatically distributes surplus to neighbors by priority
- 3The system handles flows automatically: home → battery → neighbors
- 4Receive monthly payments at the group market price
If you're a neighbor
- 1No installation needed — just a smart meter (already in 90% of homes)
- 2Get notified when cheap energy is available
- 3Optional: auto-start your boiler or heat pump when the green signal is on
Technical constraints
All group members must be served by the same transformer substation. Maximum radius: 2 km for low voltage, 4 km for medium voltage. This is a physical grid constraint — not a platform limitation.
First markets: Portugal (DL 15/2022) and Spain (Real Decreto 244/2019). Similar laws exist across most EU countries under the RED III directive.
