Cernay-lès-Reims, France – TagEnergy is set to construct France’s largest battery energy storage system (BESS) in Cernay-lès-Reims. The 240MW/480MWh project will be five times larger than the country’s current biggest operational battery.
Battery storage deployment is accelerating rapidly in Europe while significant regulatory adjustments are underway in France and the EU, making this a critical moment for companies to understand and follow the evolving legal landscape before committing to projects. Battery energy storage systems (BESS) are a key lever of the energy transition.
The bankability of battery storage projects depends on the facility’s ability to deliver expected performance throughout its lifetime (capacity in MW and MWh, round-trip efficiency, availability and cell degradation).
Battery storage operators can generate revenues through their participation to the capacity mechanism. Under this system, operators must have their capacity certified by RTE in exchange for a commitment to make their batteries available during peak periods.
