Neoen Inaugurates Breizh Big Battery in Brittany
French independent power producer Neoen has officially inaugurated the 92 MW/183 MWh Breizh Big Battery located in Pleyber-Christ, Brittany. This significant milestone marks the company's fourth battery energy storage system (BESS) in France, reinforcing its commitment to the national energy transition and grid stability.
Grid-Forming Technology Trial
The Breizh Big Battery is not only a major capacity addition but also a pioneering testbed for advanced grid management. The facility is participating in a specialized trial led by the French transmission system operator, RTE. The objective of this trial is to switch the inverter operation from a traditional grid-following mode to an advanced grid-forming mode through a software retrofit.
Grid-forming inverters are crucial for maintaining grid stability as the share of renewable energy increases, providing essential inertia and voltage support without relying on conventional synchronous generators.
Project Execution and Future Developments
The construction and assembly of the Breizh Big Battery were executed by Huawei and Equans, who successfully completed the project within an impressive 18-month timeframe. This rapid deployment highlights the maturing supply chains and development processes within the French BESS market.
Beyond the Breizh project, Neoen continues to expand its footprint across France. The company is currently constructing a massive 248 MW/496 MWh facility at Vernou-la-Celle-sur-Seine. Once completed, this site will be recognized as the largest battery storage installation in the country, further solidifying Neoen's position as a leading player in the European energy storage sector.
