TenneT and Fluence will enhance transmission capacity of the German grid with two Grid Boosters

• TenneT selects Fluence to develop and build two Grid Boosters at the substations in Audorf Süd in Schleswig-Holstein and Ottenhofen in Bavaria
  
• The battery-based energy storage systems, with a combined power capacity of 200 MW, will increase transmission capacities of existing power lines, minimise grid interventions, increase renewable penetration, reduce grid expansion, improve security of supply, and help reduce costs to consumers
  
• TenneT’s innovative Grid Booster concept will use Fluence Ultrastack, an advanced energy storage product designed for transmission grids, which has been developed and tested in Fluence’s technology centre in Erlangen, Germany
  

BAYREUTH, Germany and ERLANGEN, Germany, July 11, 2023 (GLOBE NEWSWIRE) -- Transmission grid operator TenneT and Fluence Energy GmbH (Fluence), a subsidiary of Fluence Energy, Inc. (NASDAQ: FLNC) today sealed their cooperations on two Netzboosters (Grid Boosters) with a contract signing at Fluence’s technology centre in Erlangen. The Grid Boosters will deploy Fluence Ultrastack, an advanced energy storage product that’s designed to meet the high asset availability requirements of critical infrastructure. The battery-based energy storage systems will reduce system costs for consumers by minimising the need for grid interventions and reducing the need for grid expansion measures. TenneT is integrating the two Grid Boosters into the transmission grid at two strategically located grid nodes: Audorf Süd in Schleswig-Holstein and Ottenhofen in Bavaria. This allows TenneT to integrate more electricity from renewable generation, as the existing grid can be operated with a higher transmission load.

“Germany faces new challenges in a rapidly transforming power sector, including growing renewable generation capacity being situated far from load centres. Grid Boosters can be deployed faster, more cost effectively, and more flexibly than traditional grid infrastructure,” said Roman Loosen, Fluence’s Chief Business Operations and Transformation Officer. “Combining Fluence’s leading energy storage products and services with Tennet’s forward-thinking approach to grid management, the Grid Boosters play a critical role in strengthening the transmission system and symbolise the significant investment we are taking to advance clean tech innovation in Germany.”
