About NW
Company overview
NW (private group, led by Jean-Christophe Kerdelhué)
Paris, France
Not specified
Approximately 150 employees worldwide, with one third women (source: nw-groupe.com).
What they do
NW is a technology and energy infrastructure company based in Paris, specialising in distributed battery energy storage, electric vehicle charging, energy market optimisation and grid services (source: nw-groupe.com). The group structures its activities around three integrated pillars: infrastructure, energy and technology. NW develops, finances, builds, operates and digitally optimises battery energy storage systems (BESS) and rapid charging infrastructure for electric vehicles (source: nw-groupe.com). Its flagship product, the JBox®, is a modular electricity storage unit connected to the distribution grid, while the IECharge® is a high-power charging station integrated with the JBox, enabling rapid charging without overloading the local grid (source: nw-groupe.com). NW also offers TIEBox® for commercial and industrial clients, as well as TIECharge® for rapid charging (source: nw-groupe.com). The company stands out for its fully vertically integrated approach, covering development, construction, operation and commercial optimisation of its assets, with a strong focus on digitalisation and software innovation (source: nw-groupe.com).
Projects and achievements
In France, NW operates around 1,000 JBox units and nearly 150 IECharge stations, 20% of which are interconnected to provide both storage and rapid charging (source: nw-groupe.com). The first JBox project was installed in Jonzac (Charente-Maritime), while the first IECharge station was inaugurated in Vezin-le-Coquet (Ille-et-Vilaine), illustrating NW’s integrated model (source: nw-groupe.com). NW claims more than 1 GW of operational capacity and is targeting 5 GWh of capacity by the end of 2027 (source: nw-groupe.com). In Finland, over 200 JBox units are already in service, making the country a key platform for Nordic expansion, particularly due to the high share of renewable electricity and the need for grid flexibility (source: nw-groupe.com). In Germany, NW has signed an agreement with KlarVolt to deploy 500 JBox units by 2029, to strengthen supply security and grid stability (source: nw-groupe.com). The Nordic and Baltic expansion strategy aims for 1 GW/3 GWh of storage, with the Finnish subsidiary serving as a springboard to Sweden and the Baltic countries (source: nw-groupe.com).
Recent news
In 2023, NW Storm, a subsidiary of the group, was selected for the French Tech Next40 cohort, highlighting the JBox and IECharge technologies and their ability to enable rapid charging without destabilising the grid (source: nw-groupe.com). NW announced an investment plan of €1.2 billion by 2030 in energy storage and charging stations, with 2 GWh of batteries and more than 600 high-power charging stations already in operation at the time of the announcement (source: nw-groupe.com). The group also secured €220 million in HoldCo financing from EIG, aimed at accelerating expansion in France, Finland, Italy and Sweden, with a target of 4.6 GWh of operational capacity by the end of 2027 (source: nw-groupe.com). The agreement with KlarVolt for 500 JBox units in Germany and the Nordic-Baltic strategy are also major milestones in recent expansion (source: nw-groupe.com; source: nw-groupe.com).
