Luxembourg moves forward with energy sharing

Luxembourg is taking another step toward a more decentralised electricity system. The Institut Luxembourgeois de Régulation (ILR) has opened a public consultation on new rules governing how locally produced electricity can be shared between consumers and within energy communities.

The consultation follows changes introduced by Luxembourg’s electricity-market law in April 2026. It focuses on practical questions such as how shared electricity is allocated, how data is exchanged and which responsibilities fall on the different participants. The consultation remains open until 27 September 2026.

The concept is relatively simple: instead of exporting all surplus electricity from a photovoltaic installation to the grid, producers can share part of that electricity with other participants. Luxembourg’s smart meters measure production and consumption in 15-minute intervals, allowing locally generated electricity to be allocated between members of a sharing group.

This creates interesting opportunities for apartment buildings, commercial properties, industrial sites, business parks and local renewable-energy projects. A company with a large photovoltaic installation, for example, could potentially share surplus production with other participating consumers rather than treating each connection as an isolated energy system.

For engineers and energy managers, the development is particularly interesting because it connects renewable generation, smart metering, energy management and local optimisation. Combined with battery storage and flexible consumption, energy sharing could become another tool for improving the utilisation of locally generated renewable electricity.

The transition is therefore not only about producing more renewable energy — but increasingly about using the energy we already produce more intelligently.
