Smart grid protocol: OpenADR

As the use of distributed energy resources increases, secure smart grid protocols are necessary to optimize the use of our existing physical grid infrastructure.

One such protocols is OpenADR, which stands for Open Automated Demand Reponse. This is an open standard / protocol developed by the OpenADR Alliance.

OpenADR can be used by Distribution System Operators (DSOs) to implement so-called demand response programs. These send price signals or usage limits to large consumers when needed, thus reducing peak loads and alleviating pressure on the grid.

Our project, called OpenLEADR-rs, offers an open source implementation of OpenADR version 3, that is suitable for many environments. Written in Rust, it's a lightweight and reliable a building block for a multitude of digital products and services underpinning the energy transition.

What We've Done

Tweede golf started development in June 2024 with initial funding from ElaadNL, the Knowledge & Innovation center for the joint Dutch grid operators that researches and tests smart and sustainable charging of electric vehicles.

To enable global collaboration and ensure neutral governance, the project became part of the Linux Energy Foundation OpenLEADR project in October 2024.

Current Status

As of August 2025, the project is gaining traction, in particular in the Netherlands. Funding for maintenance until mid-2026 has been secured. Additionally, the project is actively seeking funding for future development and community involvement.

Priorities

  • Publishing an official field-test-ready release
  • Implementing OpenADR 3.1
  • Implementing an alternative (non-MQTT) notification mechanism
  • Improving the testing infrastructure
  • Continuing involvement in the development of the OpenADR specification
  • Continuing community building and contributor support
