Chapter 01
The challenge
Luminus had identified residential flexibility as a strategic priority. The assets were in the field — household batteries paired with rooftop PV, growing fast across Belgium. The question was whether they could be operated as a structured energy portfolio, not just a fleet of devices.
The barriers were structural: fragmented hardware, real-time control under tight market windows, auditable measurement and verification, and a customer experience that couldn’t be compromised in the process.
