LF Energy Summit Europe 2026

OpenADR is a protocol to connect the grid to smart energy. Utilities send events to EMS & aggregators, who adapt scheduling for their flexible assets to improve thr local grid situation.

In this session, we bring OpenADR to an actionable implementation, fully based on open-source software (two LF Energy projects, in fact!). We present a new plugin to the Cloud EMS FlexMeasures, which enables FlexMeasures sites to receive OpenADR events (acting as an Virtual End Node or "VEN", in OpenADR terms). OpenLEADR is used to add such signals from the utility side (acting as a Virtual Top Node, or "VTN").

The use case we present in this session is that a utility sends congested time slots on a daily basis to charge point operators in its network. This use case is currently being piloted in the Netherlands with OpenADR.
We will show how utilities can enter and broadcast these congestion signals with OpenLEADR. The CPOs will take these dynamic limits into account in their optimized charge scheduling. We'll show how an existing behind-the-meter orchestration is built in FlexMeasures (where much more than "just" EV charging can be modelled), and how the new event will influence this planning.
