IES process

IES develops a manual and guidelines for the practical implementation of the adapted process for ensuring interoperability in the energy sector as well as a software tool for interoperability testing. The project team designs and demonstrates a modular process chain for data exchanges in the energy sector:

  1. Identify use cases where interoperability is an issue and specify these by identifying system borders and requirements.
  2. Jointly identify how certain interoperability issues can be prevented best and specify it normatively as Integration Profile.
  3. Test independent prototype solutions against each other on annual plugfest 'Connectathon Energy' and improve the Integration Profiles until it is fix.
  4. Publish successful testing activity: who has successfully tested an Integration Profile

The core idea of this methodology is lively cooperation. Users and vendors participate in the process as peers and jointly contribute to the development of demand oriented solutions. All peers participating in a test case have a common goal: they want to pass the test. The Connectathon Energy provides the environment and time to learn and make corrections to the implementations. Comments and errors recorded at the Conenctathon are valuable and powerful input for improvement of the Integration Profiles. This feedback is practice driven and thereby supports the Integration Profiles in becoming a reliable basis for interoperable systems development.
