Request for Proposal for interoperability in Home Energy Management
Open Date: 24 July 2025
Close Date: 19 Sept 2025 (17:00 CET)
Eligible organisations
Suppliers of HEMS solutions (HEMS vendors, EMS providers, manufacturers, and aggregators) and Suppliers of flexible energy-intensive devices (manufacturers of batteries, inverters, EV chargers, or heat pumps)
Description
The Dutch Ministry of Climate Policy and Green Growth (Klimaat en groene groei) has issued several measures to deal with the challenges that arise from the energy transition. These measures are combined in the Dutch National Grid Congestion Action Program (LAN). An important measure involves innovative design and standardisation. In April 2025, ElaadNL and Flexiblepower Alliance Network, have started a project on this measure, entitled “An interoperable solution for Home Energy Management Systems and energy-intensive equipment”.
Main goal
To develop open-source, standardised software connectors that enable seamless communication between HEMS and selected FEIDs.
Main outputs
- Enable interoperability by supporting consistent communication across different devices and vendors by implementing selected protocols (S2, EEBUS and Matter).
- Support local and cloud integration to function both in local HEMS deployments and cloud-based HEMS, including hybrid solutions with cloud device relays.
- Ensure secure and reliable communication by implementing security features as defined by each protocol, ensuring authentication, encryption, and session integrity across all components.
- Support selected use cases. Any logic and additional interfaces required to support these use cases are expected to be part of the HEMS solution and are not included in the development scope of this RFP.
- Adopt a modular, documented, and testable architecture that allows multiple development teams (consortia) to contribute effectively and ensure long-term maintainability.
