NW, French leader in battery energy storage systems (BESS), is working through its subsidiary NW Finland to become the strategic platform for battery energy storage in the ordic countries by 2027. This expansion will enable Finnish expertise to be exported to Sweden and the Baltic countries in the first instance.

Recognized as one of Europe’s leading energy groups, NW aims to deploy 1GW/3GWh in the Nordic and Baltic countries. This pan-European expansion is supported by its subsidiary NW Finland and enables the export of Finnish expertise. In Finland, more than 200 storage units, known as JBox^®, are already in service to support the country’s ambitious energy transition.

JBox^® units play an essential role in local and national electricity grids. They provide a balancing solution in Finland where more than 55% of the energy mix is supplied by renewable energies. They enable the integration of wind and solar energy into the electricity system and mitigate price fluctuations in the electricity markets. Deployed in remote locations, they also help to ensure a reliable electricity supply for municipalities and businesses.

In order to expand into Sweden and the Baltic countries, NW will draw on the expertise it has acquired in Finland and France. This expertise is part of a local approach and long-term vision, with supervision of all projects from development and commissioning through to operation. This expertise guarantees the quality, sustainability, and successful integration of each project into the electrical system.

« NW is already the largest developer and operator of battery energy storage systems (BESS) in France,with more than 1000 MWh of assets in operation. The group aims to become a key player in Europe’s energy transition. We are proud to be at the forefront of a more resilient energy future that can withstand shocks, adapt to crises, and continue to function even in the event of disruptions », said Jean-Christophe Kerdelhué, Executive President of the NW Group.

NW, one of Europe’s leading energy pure players operating battery energy storage systems (BESS), has secured a landmark €220 million HoldCo debt financing from EIG, a leading institutional investor in the global energy and infrastructure sectors. This non-dilutive growth capital will be used to advance the group’s expansion.This non-dilutive growth capital will be used to advance the group’s expansion.

The financing will support the development and construction of NW’s small-scale, distributed BESS assets – known as JBox^® – across France, Finland, Italy and Sweden, enabling NW to reach 4.6 GWh of operating capacity by the end of 2027. The facility underpins the company’s continued pan-European expansion as demand for flexible and decentralized storage solutions intensifies.

NW is already the largest BESS operator and developer in France, with approximately 1.0 GWh of operating assets, and in Finland with approximately 0.6 GWh by the end of 2025. The company operates under a highly contracted and flexible business model, leveraging modular technology to enable streamlined development, permitting, and construction timelines. NW is fully integrated across the BESS value chain, from development and construction through to operation and commercial optimization.

The facility, provided by EIG, demonstrates the growing availability of innovative financing solutions for differentiated BESS business models and reflects strong lender confidence in NW’s robustness and execution capabilities. This facility is among the first of its kind in this space, providing non-dilutive capital at scale at the platform level to accelerate the growth of NW’s portfolio and triple its operational capacity by the end of 2027.

With this financing, NW will have raised over €1 billion since its inception in 2018, keeping its founder, Jean-Christophe Kerdelhué, as its majority shareholder with over 70% of the capital.

Jean-Christophe Kerdelhué, CEO and founder of NW, commented: “This financing, which is rare in our field of expertise given its size and structure, is yet another indication of the strength of our subsidy-free business model, which covers three areas: Infrastructure, Energy and Tech. NW is currently the market leader in BESS storage in France and Finland. We are proud, together with EIG, to be at the forefront of the energy transition.”

Walid Mouawad, EIG’s Global Head of Energy Transition, said: “EIG is proud to support NW’s ambitious vision for a cleaner, more resilient energy future. This innovative financing reflects our confidence in NW’s demonstrated business model and leadership in battery energy storage. Together, we are accelerating the deployment of flexible, decentralized solutions that are essential for the energy transition across Europe and beyond.”

Augusta & Co acted as exclusive financial adviser to NW on this transaction.

Mobilize, the Renault Group brand dedicated to new mobility, and NW, the French leader in electricity storage and the first French unicorn in energy transition, announce the signing of an agreement to create a joint-venture in the field of electric vehicle charging combined with energy storage.

The future joint venture aims to reduce charging costs for electric vehicle users while maximizing the use of decarbonized electricity. Through this partnership, Mobilize and NW are committed to implementing innovative solutions to facilitate more sustainable and accessible mobility for all.

The joint-venture will leverage on the complementary strenghts of Mobilize and NW. Mobilize brings its in-depth knowledge of electric vehicles and charging infrastructure. Its ambition is to facilitate the transition to electric vehicles by offering charging solutions tailored to the needs of individuals and businesses, whether at home, at work, or on the go.

On the other hand, NW provides its expertise in electricity storage and charging infrastructure, with a global capacity of nearly 1 GWh and recognized expertise in managing the needs of the electricity market.

“At Mobilize, we are committed to playing a key role in the energy transition. This alliance with NW allows us to combine our expertise to offer charging and energy storage solutions that are both innovative and sustainable. Together, we aim to transform the European energy landscape and address the energy challenges of tomorrow,” says Gianluca De Ficchy, CEO of Mobilize.

For NW, the concept of Industry 4.0, also known as the fourth industrial revolution, represents a new way of organizing production resources.

This industry of the future enables the convergence of digital technology and digitalization with products and/or physical world infrastructures.

We have the potential to create a unique and innovative offering that will accelerate the use of the watture*”

*According to Petit Robert 2024, “watture” is a feminine noun referring to a wheel-based vehicle powered by electricity, intended for the terrestrial transport of a few people and their luggage. It is a play on the word “voiture”, which means “car” in English.

With the ambition to take concrete actions for the energy transition, Nidec, a world leader in stationary energy storage systems, and NW, the first French unicorn in the energy transition, are joining forces to deploy 2.5GWh of storage capacity in France by 2028. These future developments are part of the collaboration between Nidec and NW that began in 2018.

Two solid areas of expertise in the storage sector. Nidec is a specialist in the supply of customized electrical systems that improve energy efficiency, backed by over fifty years of experience. With more than 500 MW installed, NW is the French leader in energy storage.

Working together for the development of renewable energies… Today, Nidec is joining forces with NW to deploy 2.5 GWh of storage capacity in France over the next four years. With the growth of renewable energy, which is by nature intermittent, the power grid needs more flexibility. Energy storage meets this need.

… by offering French solutions. A large number of JBox® distributed energy storage units will be installed throughout France. Developed by NW since 2018, the JBox® is a solution based on lithium-ion battery technology. It takes the form of a plug-and-play container assembled at Nidec’s Saint-Etienne plant. These energy storage units provide frequency ancillary services to the power grid. The first deployments are planned for June so that these units can participate in the automatic frequency restoration reserve market, which will open at that time.

“We are very pleased to continue our collaboration with Nidec, our long-standing partner. These new projects are an important step in the development of our storage units in France. With its commitment to energy efficiency, Nidec shares NW’s vision of providing innovative technological solutions that make the energy transition accessible to all”.”
