German premiere: the first “Wind + Storage” innovation project soon to be implemented


A landmark project for the German energy transition will be built about 100 kilometers north-east of Berlin in the municipality of Randowtal (Uckermark). Juwi, the Wörrstadt-based specialist for project development and operations management, is set to build two multi-megawatt class wind turbines and a battery storage facility at the Schmölln II wind farm in the coming weeks. In September 2020, the company won a call for tenders for this innovative project as part of the first national innovation call for tenders from the Federal Network Agency. So far, this is the only such ‘Wind + Storage’ project in Germany. Electricity is repaid with a fixed market bonus as well as with a Power Purchase Agreement (PPA) that juwi jointly developed with MVV Trading GmbH. Project and PPA has now been acquired by CEE Group, based in Hamburg.

“We are delighted that we were able to get the project thanks to our expertise in tendering,” says juwi board member Dr Stephan Küßner. “The award for the wind energy storage combination is a testament to our innovative approaches to integrating renewable energies into the grid. ”

The CEE Group, asset manager for renewable energies and buyer of the project, also considers this merger as an important next step for the energy transition. Detlef Schreiber, CEO of the CEE group, explains: “Security of supply and grid stability are key challenges in the energy transition. The interaction of energy production and energy storage within a single renewable energy project indicates a solution to this particular challenge. For this reason, we decided early on to acquire this project from juwi with an appropriate PPA from MVV Trading. We have a long-standing and extremely successful collaboration with juwi, which continues in this innovative project. ‘

The on-site infrastructure is currently being prepared for the construction of the two Vestas V136 wind turbines, each with an installed capacity of 3.6 megawatts. The components of the system are to be delivered and installed from mid-November, so that commissioning can take place by January 2022. Although this part of the project is more of a routine activity for the juwi group more 25 years, the construction of the additional storage unit is uncharted territory in Germany. Planned is a lithium-ion storage unit with a capacity of three megawatt hours of Smart Power and the corresponding measurement and control technology. The components will be integrated into a container (1 x 40 feet) and a 20 foot frame for the power plant. “With this solution, we are able to supply electricity to the grid more consistently than before, especially in times of low wind,” explains Frank Elbers, juwi project manager. The storage will be built towards the end of the construction phase of the wind turbines. The commissioning of the storage is planned after the commissioning of the wind turbines.

Not only is the technical concept innovative. In terms of project financing, juwi is also innovating with its parent company MVV and its partner CEE Group. In addition to the fixed market bonus that juwi obtained for a period of 20 years as part of the innovation call for tenders of September 2020, the future operator CEE Group also benefits from the Power Purchase Agreement (PPA), which juwi and MVV offer for an initial period of ten years. “In addition to several post-EEG power purchase contracts and numerous overseas PPAs, this is already the second German project with PPA for us,” says Frederik Faißt, project finance manager at juwi AG.

MVV Trading acquires the electricity from the wind farm developed by juwi and takes charge of the marketing of the flexibility resulting from the additional battery storage operated by EEC at a fixed price guaranteed over the ten-year term of the PPA. “Commercializing wind power over a 10-year period under a PPA poses particular challenges for an energy trader. And implementing this in combination with a marketing solution for the flexibility of an associated battery storage system was a very special challenge, ”says Stefan Sewckow, Managing Director of MVV Trading. Sewckow continues: “We are proud to be able to contribute to the success of the energy transition with this product solution.

Debt financing for the project was taken over by Berliner Volksbank.

Project partners juwi, CEE Group and MVV Trading will sign the project contracts on September 15 from 11:00 a.m. to 12:00 p.m. at the joint MVV, juwi and Windwärts booth in hall 4, booth 4C10, and answer questions afterwards.

From September 14th to 17th, those interested will find juwi, MVV and Windwärts at their joint stand in Hall 4, Stand 4C10.
