World's Largest Storage-as-Transmission Project Announced by Fluence and TransnetBW

ERLANGEN, Germany, Oct. 05, 2022 (GLOBE NEWSWIRE) -- Fluence Energy GmbH (“Fluence”), a subsidiary of Fluence Energy, Inc. (NASDAQ: FLNC), a leading global provider of energy storage products and services, and cloud-based software for renewables and storage, and TransnetBW GmbH, the transmission system operator in the German state of Baden-Württemberg, announced today they would deploy the world’s largest battery-based energy storage-as-transmission project. The project will improve energy security and significantly support Germany’s energy transition pathway by increasing the efficiency of the existing grid infrastructure.
The 250 MW battery-based energy storage system, supplied by Fluence, will be located at Kupferzell, a major grid hub. It is planned for completion in 2025 and will reduce operating costs of Germany’s transmission system. The Netzbooster project will lower the number of required preventive measures in system operation, while also increasing the utilisation of the electricity grid, thus reducing the need for traditional network reinforcement and expansion.
This 250 MW Netzbooster (“Grid Booster”) project is being deployed by Fluence and TransnetBW to increase network utilisation across the German transmission system by using battery-based energy storage.
The Netzbooster initiative was first introduced in 2019 as an innovative concept under the 2030 German grid development plan. The TransnetBW Netzbooster will allow for the more efficient operation of existing transmission infrastructure and lower preventive redispatch measures. This will reduce the need for conventional network reinforcement and operating costs, thus decreasing network charges and ultimately energy costs to consumers. The system will also ease bottlenecks stemming from transporting wind energy from Germany’s north to the country’s southern load centres. In the event of a failure in the transmission grid, the TransnetBW Netzbooster system will react within milliseconds to provide back-up capacity to maintain power system stability.
“We are proud to work with TransnetBW, a forward-thinking TSO that leads the way in the application of innovative technologies that futureproof power networks, stabilise energy costs to end-users, and increase renewable deployments. Realising the Netzbooster project marks a turning point to accelerate the buildout of energy storage at the transmission network level in Germany and across Europe,” said Paul McCusker, SVP & President EMEA at Fluence. “We look forward to delivering this highly complex energy storage application at a scale required to support the country’s energy transition. Given the current energy crisis impacting Europe and the focus on accelerating renewable buildout under the RePowerEU plans, the deployment of this project is more urgently needed than ever.”
Dr. Werner Götz, CEO and Chairman of the Executive Board at TransnetBW, said, “To secure the industry leading energy storage supplier to deliver our Netzbooster project is highly pleasing, but also underlines our high standards and expectations.”
The project builds on more than 14 years of energy storage deployments by the Fluence team. This new application in Germany will further serve as a proof-of-concept highlighting the value of battery-based energy storage for enhancing transmission infrastructure and driving deployment throughout Germany, Europe, and across the world. To support the transmission network, the highly advanced system will deliver a suite of complex services, including synthetic inertia, dynamic voltage control, contingency support, and congestion management, among others. The use of energy storage to support transmission and distribution networks is expected to scale quickly, as network congestion caused by increasing renewable penetration will require greater grid reinforcement and release interventions. Research group S&P Global forecasts 17 GW / 50 GWh of energy storage systems to be deployed globally through 2030 to enhance or defer investment into upgrading existing electricity network infrastructure.
“Fluence is committed to accelerating Germany’s energy transition. Working with TransnetBW to deliver this Netzbooster project will result in a critical contribution to the country’s energy security and the stabilization of energy costs,” said Markus Meyer, Managing Director at Fluence Energy GmbH. “Through our advanced product capabilities, extensive energy market experience, and expert knowledge of complex TSO-specific applications, Fluence is well positioned to serve as a key long-term partner to TSOs in Germany, Europe, and globally, in deploying energy storage as the backbone of modern, resilient, and decarbonised energy systems.”
Notes to Editor
About the Netzbooster Project
In Germany, most of the new on-shore and off-shore wind assets are being built in the wind-swept north of the country. Nuclear and coal power plants, many of them located in the south and near big industrial load centers like Munich or Stuttgart, are being shut down. As a result, the German grid operators are building new lines to bring ‘green power’ generated up north to the load centres in the south. However, to ensure a secure power supply, grid operators cannot utilise all transmission lines to their full capacity. They need to ensure the system would still be able to operate securely if one of those transmission lines fails.
In a new innovative approach, the German transmission grid operator TransnetBW is building a 250 MW storage asset at a strategic network node. The project, known as Netzbooster, will allow the grid operator to increase the utilisation of its existing and new power lines, and in the event of a transmission line failure, the battery will respond within milliseconds to keep the power system stable.
The Netzbooster battery system will be sized to allow it to operate at full capacity for one hour to manage contingency events. This will give the TSO sufficient time to activate slower but more enduring measures like the ramping up or down of conventional generation to manage the contingency event. After each activation, the battery will be charged and remain in that state of charge during normal system operation. The currently planned Netzbooster project is meant as an initial deployment to gain experience with the large-scale application of this new operational concept of reactive system operation. Given a positive evaluation, additional projects can be expected in the future.
