Financing cross-border cooperation

The scope and the components covered by the CB RES status are described in a technical document accompanying the regulation (July 2026). 

• ELWIND a joint hybrid offshore wind park between Estonia and Latvia with a total capacity up to 1 GW
• Goerlitz Zgorzelec: a cross-border district heating in a twin city at the border between Germany and Poland, aims to replace all of its energy sources with a combination of renewable energy technologies such as biomass, heat pumps and solar thermal
• CICERONE (Alliance Cross-Border-European Green Hydrogen Value Chain): it aims to set up a cross-border European green hydrogen value chain between Italy, Spain and Germany. Renewable electricity produced in Spain and Italy will be converted to green hydrogen, and transported to the Netherlands and Germany
• SLOWP (Saare-Liivi Offshore Wind Park): a joint hybrid offshore wind park between Estonia and Luxembourg, with a total capacity of 1.2 GW
• ULP-RES WP (Utilitas Lode-Penuja RES wind park): an onshore wind park between Estonia and Latvia, consisting of new generation wind turbines with joint connection to the transmission grid in Latvia, with total power production capacity of 200 MW
• TMNHSA (Turnu Magurele – Nikopol Hydraulic Structures Assembly): a project that aims to build twin run-of-the-river hydropower plants with a total capacity of 840 MW on the Danube at the level of the cities of Nikopol, in Bulgaria, and Turnu Măgurele, in Romania
• BEI (Bornholm Energy Island):a hybrid project that consists of 2 offshore wind farms of 3 GW each, to be connected to converter stations on the Danish island of Bornholm. The island will be connected to both Denmark (mainland) and Germany through high-voltage direct current cables
• Liivi Bay Offshore Wind Farm: the project aims to deliver a large-scale offshore wind farm in the Baltic Sea. Built in Estonian waters in the Gulf of Riga, it will be radially connected to the Estonian national grid, and is expected to reach 1 GW of installed capacity and to start generating electricity from 2031. The wind farm will contribute to Estonia’s goal of producing 100% of electricity from renewable sources by 2030, while also supporting Latvia’s energy transition
• Utilitas Eleja-Jonišķis Wind Park: spanning across the Latvian-Lithuanian border, the onshore wind park will reach 200 MW of installed capacity from 2028, offering a strong boost to renewable energy supply in both countries. The project is strategically located to connect to the 330 kV Viskaļi–Mūša transmission line, enhancing regional grid stability and energy independence
• Comprehensive Offshore Renewable Energy Studies (CORES): the project paves the way for groundwork for the future cross-border deployment of floating offshore wind energy in Portugal in cooperation with Luxembourg. It will assess offshore wind zones, grid reinforcements, and auction models, helping to unlock up to 10 GW of offshore wind capacity in Portugal. The project also fosters collaboration around green hydrogen, port infrastructure, and energy system planning
• Medlink Renewable Generation (MedGen): this landmark North-South cooperation project aims to install 10 GW of solar and wind capacity in Algeria and Tunisia, with dedicated battery storage systems. Two 2 GW HVDC interconnectors will export up to 22.8 TWh/year of clean electricity to Italy (outside the scope of the CB RES project). This makes MedGen a flagship initiative, boosting sustainable development, regional integration, and the EU’s energy diversification efforts
• Twin Heat: the project will decarbonise the district heating systems of the twin cities Słubice (Poland) and Frankfurt (Germany) through the installation of renewable-based heating infrastructure, including biomass boilers and cross-border heat exchange. The project is an example of thermal energy integration, contributing to lower emissions, cleaner air, and increased energy efficiency in urban heating systems
• Wind Integration for Network Decarbonization – WIND: the project consists of a 650 MW onshore wind farm at Poltavska in Ukraine with foreseen exports to Romania
• Deploy: the project is a cross-border integrated powerplant between the cities of Guben in Germany and Gubin in Poland. It will connect 115 MW of onshore wind and 65 MW of solar PV installations located on the Polish side of the border to the industrial customers and a grid connection point in Germany. The project also involves converting the electricity produced to heat into both sides of the border
• ZEGA-LINK: the project consists of connecting a 5 MW heat pump to the district heating network of Simbach, Germany, and building a geothermal plant of 15 MW in Braunau, Austria, along with complementary heat network reinforcements

• The fifth call for works and studies will be published in Q4 2026 once the 5^th CB RES status list enters into force. 
• A fourth call for works and studies was published on 4 November 2025 and closed on 12 March 2026. On 17 September 2026, the Commission selected 3 projects to receive a total of €125.8 million for construction works. The projects will support cross-border energy infrastructure and contribute to the EU’s decarbonisation and energy integration objectives. 
• A third call for studies and works opened on 22 October 2024 and closed on 16 January 2025. On 22 September 2025, the Commission selected 3 projects to receive a total of €76.3 million to help foster cross-border cooperation in renewable energy, increase the deployment of clean energy solutions, and contribute to achieving the EU’s energy and climate objectives.
• The second CEF Energy call for studies and works closed on 6 February 2024. The Commission decided to grant a total of €67.4 million to 2 project proposals for works and 3 for studies. The projects cover various renewable energy technologies, such as offshore and onshore wind, district heating and green ammonia processing and involve 5 EU countries: Estonia, Germany, Latvia, the Netherlands, and Poland.
• The first dedicated CEF Energy call was published in 2022. As a result, 2 of the projects - ELWIND and CICERONE - were selected to receive grants for studies worth a total of €22 million to help them advance the projects through environmental impact assessment, geological and sea basin research, spatial planning and front-end engineering.
