With the OLI dApp you can identify and choose the source of your consumed electricity. Switch your electricity tariff on a quarterly hour basis or take part in your local energy community.

Buy from your friends and neighbours and leverage local, clean and green energy production capacities. Or become a seller yourself and use your excess electricity in an optimal way.

The main processes like tariff switching and the price setting on the market are being done with a distributed ledger to help keep things decentralized, transparent and secure.
