Frequently Asked Questions

General Questions

Other legal entities that participate in Horizon 2020 by carrying out some tasks in an action, but which do not sign the Grant Agreement (including entities linked to the beneficiaries) are considered as “third parties involved in an action” (Article 8 of the Annotated Model GA). They are not bound by the terms and conditions of the Grant Agreement and consequently, the European Union (represented by the Commission or another funding body) has no obligation vis-à-vis third parties. If necessary to implement the action, beneficiaries may use contracts and sub-contracting for the purchase of goods, works or services, in-kind contributions provided by third parties and also linked third parties carrying out tasks under an action.

Eligibility & Entry Process

INTERRFACE Open Call is open to any organization eligible under Article 10 of the H2020 rules of participation, i.e. any start-ups, SMEs, companies or research institutes/organizations, with legal entity in a member state of the European Union, a H2020 associated country or in a H2020 International Cooperation Partner Country (ICPC). Entities have to possess a validated Participant Identification Code.

Please check the list of eligible countries in the following link:

Yes, Research and Technology Organisations including universities are eligible to receive funding.

No, consortia cannot participate. Only single legal entities can apply for funding.

Only one proposal per applicant can be submitted. If more than one proposal per applicant is identified, only the first one which has been submitted in order of time will be evaluated.

This is a general criterion to avoid receiving multiple proposals from the same applicants. What you describe is specific to your organisation’s structure and could be considered once and if multiple proposals are received by your institute. In this case, and should more than one proposals from your institute are successful and pass the thresholds, we would ask further information (in the form of official document) that the proposals were originated from different departments that work isolated (as you also mention, as separate entities with no common scientists, etc.).

Apply Process

No, the proposals will only be evaluated after the end of the Open Call that is the 30th of June 2021. Until then, even if you have already submitted your proposal, you will be able to resubmit your proposal.

Questions for Business Use Cases

Normally, Local Energy Communities gather prosumers with generation capacities up to a few hundreds of kW. Nevertheless, limitations for this aggregation come not only from the size but also from the distance between participating peers.

As the successful candidate will be using the platform developed in Demonstrator 5.2, the resources from the building where the IDN is installed should be considered. Hence, the minimum in terms of resources will be those from the demo building. i.e., PV with ~40pkW, Storage with 200kW and +400kWh, Max dem from building users of ~120kW, and 6 EV charging points.

The objective of BUC6 is to extensively test a wide range of distribution and transmission systems
benchmark topologies (e.g., CIGRE European HV transmission network, CIGRE European MV distribution network, IEEE 33 bus test system, IEEE 118 bus test system and others) via a scenario based approach in order to identify generic indicators that can be used for the quantification of congestion management requirements.

The BUC6 implementation requires a detailed knowledge of various softwares (PowerFactory-Digsilent™, MATPOWER™  and Power System Analysis Toolbox™). 

The Demo Area covers the Greek, Romanian and Bulgaria power systems.
As a consequence, the knowledge of the Greek power system is a prerequisite and also an expert knowledge of the Romanian and Bulgarian power systems is desirable. 

As the demo, also the algorithms and solutions to be provided should run in an “on premise” mode and these SW requirements are the technologies used in the demo.

The voltage levels refer to medium and high voltages. Both transmission and distribution networks will be equally studied and evaluated. The study will be focused on the transmission and distribution networks of Romania, Bulgaria and Greece. 

IEGSA architecture as the physical scope of the software solution was introduced during the 3rd INTERRFACE Open Call webinar on May 31st.

A software development company should represent Flexibility Service Provider(s), i.e. independent aggregator(s), and its business use case needs. The aim is to decrease barriers for Flexibility Service Providers to provide flexibility services as mFRR and congestion management products. This may involve creating Flexibility Service Providers’ interfaces to IEGSA and / or attracting more flexibility assets from the market both from residential and non-residential customers. Here innovation is sought in solutions which are offered to residential customers. has the latest versions of documents used for Transparency data and  “urn-entsoe-eu-wgedi-codelists.xsd” is just updated to the latest version.
