OptimCE simplifies the management of members, meters and energy sharing within your renewable energy community.
Everything you need to manage your energy community
Onboarding, roles, community-user links. Easily manage all participants in your community.
Track each member's energy meters and centralise consumption and production data.
Configure allocation keys and sharing operations to distribute energy among members.
A single instance for multiple energy communities. Built-in multi-tenant architecture.
Event-driven integration (SQS) allowing you to connect third-party tools such as an energy management system.
Open and transparent source code. Contribute, audit and adapt the platform to your needs.
A solution designed for European energy communities
Open, auditable and modifiable source code. No vendor lock-in.
Compliant with European directives on renewable energy communities and citizen energy communities.
Quick installation. Multilingual interface (FR, EN, NL, DE) and scalable architecture.
OptimCE is in alpha and part of an active research project. Here is what we commit to, today and long-term.
The hosted SaaS at app.optimce.be is free to use while we are in alpha. Like many open source projects, the hosted version may move to paid plans later — if so, you will know well in advance. Self-hosting stays free regardless.
The full source code is released under Apache 2.0 and will stay open. Audit it, fork it, contribute — no proprietary core, no rug pull.
Run OptimCE on your own infrastructure with zero restrictions. The open source core stays fully featured — no paid tiers, no feature gating. We may offer paid support or services on top, but never as a gate on the OSS itself.
Built with modern, open technologies
Angular frontend, Node.js/TypeScript and FastAPI backend, event-driven architecture. Contribute on GitHub or integrate OptimCE into your own tools via the REST API.
