Integration of batteries into a sustainable energy system

CROSSBOW project was successfully completed in April 2022. It was demonstrated that CROSSBOW solutions have high potential to contribute to a more secure and cost-efficient operation of power systems on a regional level in SEE. CROSSBOW has a great impact on the increased penetration of RES generation as a key element for a clean energy transition and as the main goal of the region for the future. Another impact is found on the development of electricity markets in close to real-time as well as their regional integration, integration of new technologies for the provision of flexibility, and increased security in the system operation as prerequisites in the process of the clean energy transition.Communication and press releases on H2020 project CROSSBOW:

    Crossbow – Kick-off and project introduction (2017)

he European Commission’s vice president in charge of the Energy Union, Maroš Šefčovic, said “[batteries] development and production play a strategic role in the ongoing transition to clean mobility and clean energy systems”.

Projects such as EU-funded CROSSBOW are underway to integrate batteries into a sustainable energy system to leverage the battery value chain, from materials to system integration and recycling.

Project CROSSBOW’s long title “Cross-border management of variable renewable energies and storage units enabling a transnational wholesale market” explains the overall objective: The development of clean energy sources involving storage units will boost the EU Commission’s efforts to secure Europe’s competitiveness in this market. Also, the reduction of the cost of the regional energy system represents another strategic goal with societal benefits, as well as the planning for the development of the electricity grids in Southeastern Europe.

cyberGRID’s role

As an ICT solution provider, cyberGRID is nominated as Task Leader in one of CROSSBOW’s technical work packages. Our involvement will entail the development of the cooperative ownership of flexibility assets and the creation of a toolset for the transnational ancillary and wholesale market, respectively. Also, substantial efforts will be invested in preparing for demonstration and validation of the platform. In particular, cyberGRID will analyze the minimum requirements for market harmonization and consult on a coordinated multi-nodal market design.

CROSSBOW results will be evaluated by 8 TSOs in Eastern Europe, validating the project’s impact through 9 common high-level use cases in at least three different countries.

Partners: CROSSBOW was kicked off in November 2017 in Sofia, Bulgaria. It currently represents one of the European Union’s most critical projects in the field of smart grids. The CROSSBOW consortium consists of 24 commercial, non-profit and academic partners, among which there are technological partners from Austria, Germany, Spain, Slovenia, and UK. The transmission system operators (TSOs) come from eight Southeastern countries in Europe (Bosnia-Herzegovina, Bulgaria, Croatia, Greece, Montenegro, the Republic of Macedonia, Romania, and Serbia).
