IntMAS - The Interoperability Management and Audit System

31 October 2025

IntMAS provides organizations with a structured framework and certification pathway for managing interoperability maturity.

The energy sector is moving fast, and interoperability is key to making the transition work. To support this, the int:net project launched the “IntMAS approved” label — a registered brandmark awarded to organisations that have successfully implemented the Interoperability Management and Audit System (IntMAS).

What is IntMAS?

IntMAS is a management framework designed to help organisations across the energy ecosystem — from technology providers and test labs to associations and communities. Inspired by proven management tools such as EMAS, ISO 9000, and ISO 50001, IntMAS provides a structured process for achieving interoperability maturity.

Rather than a one-off effort, IntMAS ensures continuous improvement and encourages collaboration across sectors such as buildings, mobility, manufacturing, grids, and beyond.

Why does it matter?

By adopting IntMAS, organisations can:

Ensure reliable and future-proof integration of energy solutions.
Promote structured, continuous improvement.
Build trust with partners, customers, and regulators.

In a rapidly changing energy landscape, IntMAS helps companies demonstrate their commitment to quality, collaboration, and innovation — giving them a clear competitive edge.

How to implement IntMAS?

A guideline, an assessment system, and templates have been developed within the framework of the EC-funded int:net project. For now, candidates receive direct support from the int:net consortium.

After the project’s completion, support tools will be hosted on the IntMAS platform, where an AI-supported certification and label awarding process will also become available.

Tested and approved

Several organisations have already tested IntMAS. At the int:net Final Conference, the very first organisations achieved IntMAS approval had been officially awarded and celebrated on stage — a major milestone for the energy interoperability community.
