InterConnect provides a first blueprint for a Common European Reference Framework for energy applications for consumers

The EU funded InterConnect project, which gathers 50 European entities from the Energy and Internet-of-Things value chain, is focused on developing and demonstrating advanced solutions for connecting and converging digital homes and buildings to guarantee a cleaner, secure and affordable electrical system.

Following the adoption of the Digitalising the energy system EU action plan (published in October 2022), the InterConnect project has set as a new goal to contribute to the development of a Common European Reference Framework (CERF) for energy saving applications that allow them to make voluntary reductions in their energy consumption and help them in reducing their energy costs. CERF for energy saving applications will leverage the creation of consumer applications across Europe that will enable improvement of electricity grid resilience and stability through reduced and time-shifted consumer energy use that are encouraged through signals users may receive in their Energy App of choice. CERF for energy saving applications will allow for personal energy bill savings at the same time.

The CERF for energy saving applications blueprint delivered by the InterConnect project in February 2023  proposes a design (or pattern) that can be followed to implement instantiations of the CERF on national levels. The blueprint acts as a guiding principle and consists of technical and non-technical information such as, but not limited to, a system architecture, conditions for the Minimum Viable Product (MVP) characteristics that energy saving applications should fulfil, business use cases, terms of reference as well as interface specifications and an overview of relevant data sources.

The core developments carried out by InterConnect, namely the Semantic Interoperability Framework and the Distribution System Operator Interface, which are already publicly available, will be used to demonstrate the ability to interconnect consumers, grid stakeholders, technology enablers, devices and service providers to realize differentiating Energy Applications.

The InterConnect project will further expand the development and real-life testing of the CERF for energy saving applications by dedicating € 2M to project partners’ activities as well as to 3rd parties through a cascaded funding mechanism.  A first generation of energy saving applications will be tested within the scope of the InterConnect project, in a contained environment in at least 3 EU member states in which existing InterConnect pilots are running.  Additional EU member states will be included via the cascaded funding where companies that are familiar with the topic and are already developing energy saving applications will demonstrate their solutions in 7 additional geographies.

The overall ambition of the InterConnect project is to deliver at first stage by November 2023 a Minimum Viable Product (MVP) which will contain a working reference framework for interoperability using currently available data sources, such as DSO and TSO information, and an open source reference design  for energy savings applications. The second stage by March 2024 will consist of large-scale demonstrations of CERF for energy savings applications in 10 EU member states.

The main activities and pilots currently running can be followed at the InterConnect project website, where a detailed description of how the project is impacting the involved countries is presented.



Energy Applications Ecosystem: integration and visual interface


The Energy Applications can rely on an interoperable ecosystem composed of data sources and services to allow information about the electric grids to become available to be integrated into different interfaces and visualizers. As depicted below the implementation is made using traditional mechanisms as well as semantic adapters to facilitate the test and integration from the different pilots that will be demonstrating the energy applications.

Flexi App, the Italian Energy Application

​The Flexi App functionality has been embedded in production within the Planet App environment and will let available for 3 large scale Social Housing districts in Milano, namely Merezzate , Urbana, and Moneta.​ The Flexi App customization for the Italian case leverage on the following set of tools deployed/embedded within the InterConnect framework:​

  • Transparency Platform (ENTSO-E)​
  • Semantic Interoperable Framework (SIF)​
  • Interoperable recommender service​

Greek Pilot App

A mobile app for the Greek pilot participants of the EU-funded InterConnect project developed by AUEB-RC. The app is used for user interface/engagement purposes, monitoring of energy consumption, and remote control of devices. ​

This app is integrated with the Interoperable Recommender. ​

Greek pilot will collect KPIs based on 3 approaches:​

  • Indirect based on smart-meter consumption data compared to historical consumption patterns. This will reflect any change of consumption habits after the deployment of the recommender.​
  • Direct based on push notification feedback by the end-users​
  • Survey/Questionnaire that will be distributed at the end of the demonstration.​

The Wattch.r Portuguese Energy Application

A custom-designed application is currently available for selected participants in Portugal to get information about how consumers can support the grid and the energy system.
Everyday consumers are informed about the potential participation for the following day whilst keeping track of the current actions to be take in the current day.

It makes use of:

  • Interoperable Recommender (IRec), that provides information about the operating conditions of the EU grid and assigns the best hours in the day to increase of reduce the energy consumption.
  • DSO Interface (DSOi), that specialises the actions considering the geographies of Portuguese consumers and their impact in the distribution grids.
  • Semantic Interoperable Framework (SIF), that unites the different digital platforms via semantic representations of devices and systems.
  • Tips of the day, to help consumers to reduce their carbon footprint by adopting more sustainable behaviours.

Get to know the 2nd Open Call Energy Applications


From the 2nd Open Call a set of 7 companies started to develop their own energy applications as part of their business in creating digital solutions for buildings and grids. They are making use of the project interoperability results, namely the Interoperable Recommender, the DSO Interface and the Semantic Interoperability Framework to learn, develop and implement custom tailored energy applications to engaged their end-users. The applications are underdevelopment and soon will be announced. See their profiles below.
