The objective of the ATTEST project is to develop and operationalize a modular open source toolbox comprising a suite of innovative tools to support TSOs / DSOs operating, maintaining and planning the energy systems of 2030 and beyond in an optimised and coordinated manner, considering technical, economic and environmental aspects. The consortium, from six EU countries, that has been assembled to deliver ATTEST consists of five highly experienced research organisations in the energy systems area, two utilities that manage and operate the transmission system and the distribution system in Croatia, and two industry partners that specialise in the development of advanced ICT solutions and SCADA systems. The development of this broad spectrum of energy-related ICT tools and the utilization of next generation algorithms, demonstrated in a real world environment has not been attempted before. The outputs from the ATTEST project will enable accelerated dissemination, by a wide range of research institutions, within and outside of the project consortium, of the tools that will help TSOs and DSOs to better manage their networks. The demonstration of the results of the project will be valuable for the scientific community and EU energy industry and attest to the relevance of the solutions developed. The ATTEST’s ambition is to enable a wide range of users to utilize and test the tools developed in the project, thereby contributing to spread knowledge and experience in the energy systems community in the EU and on a global scale. This will contribute significantly to addressing not only the specific challenges of the call and the Horizon 2020 Energy Work Program, but also those of the EU’s Energy Union strategy and the 2020 Climate & Energy package.

Redox flow batteries (RFBs) are designed to work up temperature of 40ºC, however, discharging the battery generates heat. A cooling system is required to avoid electrolyte degradation or battery malfunction. Cooling requires energy and reduces the battery global efficiency. Moreover, higher temperatures have advantages: low electrolyte viscosity (less pump energy), better electrolyte diffusion in electrode & increase battery power due to increase electron mobility. BALIHT project aims to develop a new organic redox flow battery suitable to work up to temperatures of 80ºC, with a self-life similar than current organic ones, but with an energy efficiency 20% higher than current RFB since cooling system is not required, less pump energy & high power. Redox-active organic molecules with promising prospect in the application of RFBs, benefited from their low cost, vast abundance, and high tunability of both potential and solubility. These organic molecules are more soluble in water, which allows more concentrated electrolyte and increased battery capacity.CMBlu has developed an organic redox flow battery technology that use electrolytes from lignin, thin non-fluorinated membrane, carbon-based electrodes and plastic frames. Lignin is a renewable resource and the largest natural source of aromatic compounds from which efficient electrolytes can be produced. BALITH concept of organic RFB makes this technology suitable for many applications where the requirements for batteries are more challenging like: - Smoothing of non-dispatchable renewable power plants (like solar or wind) - Support for Ancillary services - High performance electric car recharge points - Improvement of grid flexibility and stability (at both transmission and distribution level). - Avoid cooling needs in RFB placed in warm countries (between 40º Latitude North & 40º Latitude South).

BEYOND brings forward a reference Big Data Management Platform, on top of which an advanced AI analytics toolkit will be offered allowing for the delivery of derivative data and intelligence out of a blend of real-life building data and relevant data coming from external sources (batch and real-time). The Analytics Toolkit will enable the execution of a wealth of descriptive-predictive-prescriptive analytics on the basis of pre-trained algorithms focusing on Personal Analytics (consumer behaviour, comfort and flexibility profiling), Industrial Analytics (Energy Performance, Predictive Maintenance, Forecasting and Flexibility analytics), along with Edge Analytics towards intelligent real-time automated control of building assets. The BEYOND Big data platform and AI Analytics Toolkit will be associated with novel data (intelligence) sharing mechanisms that enable the integration of value chain stakeholders (building and market actors), thus allowing the latter ones to gain the opportunity to acquire building data & advanced analytics and build their own applications and solutions, towards (i) providing innovative energy services to the building sector, while (ii) at the same time improving their business operations and increasing their business processes and operations (de-risked EPC, informed policy planning & infrastructure sizing). To achieve this degree of intelligence and optimization, BEYOND will leverage data, primary or secondarily related to the building domain, coming from diverse sources (data APIs, historical, sensor / IoT, weather and market data, the EU Building Stock Observatory, open building data hubs) integrated to the BEYOND Platform to enable data exchange in an interoperable and standards-based manner. BEYOND will be validated in 4 large-scale demonstrators (EL, ES, FI, RS) involving (i) data collection from diverse building typologies, data sources, building systems and devices, and (ii) data (intelligence) sharing with various market actors.

Despite the large economic energy saving potential in the EU, the energy service companies (ESCOs) market for residential buildings is much less developed than in other demand sectors (e.g. the industry or public/service sectors). Besides sector cross-cutting barriers (e.g. low energy prices, lack of information and awareness, lack of appropriate forms of finance) there are specific barriers which make a large-scale application of the ESCO model for residential buildings particularly difficult (e.g. lack scale or lack the necessary energy intensity to justify investment within the structure of present-day EPC model). In this context, frESCO aims to engage with ESCOs and aggregators and enable the deployment of innovative business models on the basis of novel integrated energy service bundles that properly combine and remunerate local flexibility for optimizing local energy performance both in the form of energy efficiency and demand side management. Such new service and business models will bring under common Pay for Performance Contracts (extended form of current EPCs) two currently differentiated service offerings to enable the realization of next-generation smart energy service packages. The strong presence of the industry in the consortium (2 ESCOs, 2 aggregators, 3 ICT and technology providers and 2 engineering companies) and the end-users (1 Cooperative and 1 Hotel), supported by 3 knowledgable RTOs, will ensure the market uptake of frESCOs new business models. frESCO's new business models will be demonstrated in 4 different pilots (Spain, France, Croatian and Greece) with complementary characteristics in terms of building typology (single-/multi-family), climate, regulation, energy consumption, energy assets, consumer groups, etc., thus facilitating the replicability of frESCO's solutions across Europe. Overall, frESCO aims to directly achieve a primary savings of 464 MWh/yr and a reduction of 108 tCO2/yr and trigger 28.3M€ investment during the replication

Nowadays, the adoption of a single and unified electricity market [1] is one of the main challenges faced by Europe. Although the Western and Northern regions of Europe have been working for several years towards reaching such objective, the South-Eastern region of Europe has not followed the same roadmap and it not as advanced in this field as Western Europe. TRINITY will address this challenge in order to improve the current situation and facilitate the interconnection of South-Eastern electricity markets - among them and also within the current Multi Regional Coupling area (MRC). TRINITY will develop a set of solutions to enhance cooperation among the transmission system operators of SEE in order to support the integration of the electricity markets in the region, whilst promoting higher penetration of clean energies. This strategic goal will be driven by end-users (8 TSOs, 4 NEMOS and 1 RCC) and will be achieved through the deployment in the region of four independent, but complementary, products: T-Market Coupling Framework; T-Sentinel Toolset; T-RES Control Center and T-Coordination Platform.
