Test Event and Conference Residential Flexibility

Thursday February 12th 2026 / Friday February 13th

Organised by ElaadNL with support from TNO and FAN

ElaadNL is pleased to invite you to participate in the first Residential Flexibility Test Event. In order to optimally support the development of interoperable communication between FEIDs and HEMS, ElaadNL expands her proven concept of testivals for EVs and chargers to domestic Flexible Energy Intensive Devices (FEIDs) and Home Energy Management Systems (HEMS).

During each test event, the performance of hardware and software brought by participants can be tested against other market products. The aim is to have established a certification process for interoperable HEMS and FEIDs by the end of 2026.

This first event will take place on Thursday February 12 and Friday February 13 in the Testlab of ElaadNL in Arnhem, the Netherlands.
Follow-ups are scheduled in 2026 for June 17 and 18 and October 28 and 29.
