Test event Residential Flexibility

Wednesday June 17th 2026 / Thursday June 18

Organised by ElaadNL with support from TNO and FAN

Join the second Residential Flexibility Test Event and help shape the future of interoperable energy solutions.
To support the development of seamless communication between Flexible Energy Intensive Devices (FEID) and Home Energy Management Systems (HEMS), ElaadNL is organising the second edition of this test event.

Participants will have the opportunity to test their hardware and software with products from other market parties in a practical, multi-vendor setting. It is a unique chance to validate interoperability, exchange insights and contribute directly to the next steps towards market-wide alignment.

Our shared ambition is to establish a certification process for interoperable HEMS and FEIDs by the end of 2026.

Watch the short film of the first test event last February.

Why join?

Test interoperability in practice, learn from other participants and contribute to the development of future certification.

The test event is open to all producers and manufacturers of equipment that is within scope: HEMS, either physical or via the cloud, and EV chargers, stationary batteries, solar inverters and heat pumps.
