The Krieger’s Flak Combined Grid Solution project is a joint Danish-German project managed by the two Transmission System Operators 50Hertz Transmission, Germany and Energinet.dk, Denmark. It is a project to combine the connection of offshore plants at Kriegers Flak with interconnections between Denmark and Germany.The traditional way to connect offshore wind power plants is to use national, radial solutions. This project will develop and implement an innovative, cross-border solution which is based on the dual-purpose use of the subsea cables for both transmission of wind energy and energy trade. Hence the aim of this project is to ensure a modular-based Combined Grid Solution (CGS) for the grid connection of the offshore wind farms at Kriegers Flak area in the Baltic Sea. The purpose of this project is in other words to secure a joint interconnection solution for the German offshore wind farm EnBW Baltic 2 and the expected Danish offshore wind farm – Kriegers Flak III.The result of this project may be the first offshore grid connection of offshore wind power which will also operate as an interconnector. When this large-scale project is completed, it will have addressed the technical challenges of designing, installing and operating a Combined Grid Solution based on the new multi-terminal HVDC voltage source converter (VSC) technology. The project will also have addressed a number of cross-border, regulatory challenges.A Combined Grid Solution at Kriegers Flak will bring renewable energy to European consumers, strengthen the energy markets and increase the security of supply by providing transmission capacity.Since the concept of the CGS project is based on the prerequisite that offshore wind farms will be built and operated in the Danish and German part of Kriegers Flak, the progress of these wind farm projects is essential for the progress of the CGS project. Achievements: EnBW Baltic 1 has been designed, built and installed with a capacity of 48.3 MW in 2010. Concerning EnBW Baltic 2 (former Kriegers Flak I), the project owner (EnBW) has entered into a contract to build the platform for the offshore substation (OSS) with the option of an extension that will accommodate the additional cable connections for the Combined Grid Solution project. EnBW Baltic 2 will have an overall installed capacity of 288 MW.
