LONDON, 28th November, 2024 – JLL's Energy and Infrastructure Advisory team acted as exclusive sell-side M&A advisor to Harmony Energy France, subsidiary of leading energy transition developer Harmony Energy. The advisory was for the sale of their 100 MW / 200 MWh ready-to-build (RtB) battery energy storage system (BESS) project located in Oise, France. The project is due to commence construction in Q3 2025, with commercial operations expected to begin in June 2026.

Following a competitive process, the project was sold to Alpiq Energie France SAS, a wholly owned subsidiary of Swiss-listed Alpiq Holding AG, which specialises in energy transition and power generation services. Once operational, it will be one of the largest standalone BESS assets in France.

The completion of this sale is a significant achievement that marks JLL’s 1st BESS transaction in France and 8th European BESS close of 2024 to date, with coverage spanning 6 geographical regions. Since 2017, JLL has advised clients on 49 transactions involving 9 GW of BESS assets across multiple countries in Europe, cementing our place as the market leading financial advisor in this sector.

Max Stirling, Director, Energy & Infrastructure Advisory, EMEA, JLL, said: “The Marronniers battery project is a pivotal transaction for the French energy storage market and will prove crucial to supporting the energy transition. Harmony have developed a high-quality asset, whose scale stands out from others in the market.”

Andy Symonds, CEO, Harmony Energy France SAS, said: “Harmony Energy is delighted to have collaborated with JLL on the successful sale of the Marronniers battery energy storage project. JLL’s expertise and dedication have been instrumental in expertly initiating and leading the transaction process and bringing it to fruition in the timeframe initially set out. This sale marks an exciting step forward for Harmony Energy as we continue to grow our presence in the energy transition, advancing our mission to deliver clean, reliable energy solutions.”
