IES Austria

Interoperability is a key factor for the successful transition of the energy system.

The Initiative IES - Integrating the Energy System provides a common understanding and framework to develop and reuse solutions for data exchange: interoperability profiles instead of proprietary solutions. The transparency of the process ensures a sustainable investment protection for vendors and fosters competition, increases product quality and performance at lower costs.


The IES-approach

The use of harmonized technical standards is a key requirement for cost-effective system integration. Communication standards allow certain flexibility in implementation, so interoperability can only be achieved through a normative application of these standards. This is done in the specification of so-called interoperability profiles


The IES methodology provides a transparent, manufacturer-neutral and cooperative process to define interoperability profiles and to test perform interoperability testing of ICT systems.

For this IES offers a tailor-made service offer for every step of the process chain. Domain experts are accompanied in a moderated process in the specification of interoperability profiles. Manufacturers who have implemented the public available interoperability profiles are supported in the preparation and implementation of interoperability tests.


The IES methodology can be used for any data exchange in digitalization.


The greater vision: From an initiative to IES Europe

It is important that harmonization processes take place on an international level to ease implementation and facilitate the required communication of decentralised energy components as demanded by the transition of the energy system. Hence, vendors and customers need fewer resources to integrate new components into an existing IT-landscape.

The cooperation between the IES initiative and relevant actors in the energy system, further European initiatives and relevant EU projects should be encouraged. The initiative offers collaboration with interested stakeholders in other EU Member States and provides expertise such as process support, training, provision of test systems and tools to support a growing community in Europe.


The Vision IES Europe is already anchored in the SET-Plan Action 4 Implementation Plan 2018, Activity A4-IA0-5 PROCESS CHAIN FOR INTEROPERABILITY OF ICT SYSTEMS. (Download here)


The specification of the Technical Framework (TF) is the centre of the IES Process (see Fig. 2)

In the first step of the process the TF is specified by experts starting with a concrete use case. The document structure is in line with Smart Grid Architecture Model (SGAM) and IEC 62559 Use Case Methodology.

IES offers process support for the specification of the TF e.g. through moderated workshops where users and manufacturers jointly determine the requirements and functionalities.


In the second step, the Technical Frameworks are the basis for the test environment, which is made available by IES. The vendors receive tailor-made support for the preparation and implementation of the testbed.


The IES Process foresees that all the specifications are accessible online. The IES methodology provides the formation of a community that supports users and manufacturers in promoting the interoperable interconnection of ICT systems in the energy system.

Test Event Connectathon Energy

IES organises a regular test event “Connectathon Energy”, which provides a detailed implementation and testing process to enable the adoption of standards-based interoperability.

During a Connectathon Energy the vendors test their system implementations: the exchange of information with corresponding systems is done in a structured and supervised peer-to-peer testing environment, performing transactions, which are carefully defined in the interoperability profiles of the Technical Framework.


Synergies achieved through cross-sector knowledge transfer with the healthcare sector

By initiating a cross-sector knowledge exchange, the initiative IES draws from 15 years of experience and know-how in the healthcare sector, where systems interoperability has been implemented for a long time, see the global organization IHE - Integrating the Healthcare Enterprise.

  • Worldwide reference for the successful, established ISO/TR 28380 methodology comming from the IHE
  • Synergies through the use and reuse of already existing profiles, e.g. for security and privacy
  • Usage of the proven open source test platform Gazelle also for the energy sector




This was the Connectathon Energy 2019

The Connectathon Energy 2019, taking place from the 28th until the 31st of January in Vienna was a complete success. With about double the number of active participating companies and research institutes and a well visited workshop and symposium the message was clear: Interoperability is a key factor for future energy development and people can clearly see and understand its importance.
