Your energy community, managed to the quarter-hour

OptimCE is the open source platform that brings together your community's members, meters, allocation keys and billing. Use it online or host it yourself.

Free software under the Apache 2.0 licence, on GitHub

Each square is a quarter-hour: 96 a day.

Example: a 24 kWp roof and 12 households in Namur. Generation computed with PVGIS and the 2023 weather on the same dates; consumption from a typical profile of 3,500 kWh per household per year.

How it works

Three steps, from registering members to the invoice.

  1. Register members and their meters

    Each member joins the community with their meter. OptimCE brings its readings together, quarter-hour by quarter-hour.

  2. Choose the allocation key

    Build it in a grid or step by step, then compare scenarios on your own data with the simulation.

  3. Bill and report

    For each billing period, OptimCE bills each member for the shared energy and prepares the filings for the Walloon regulator (CWaPE).

What the app does
