Neoen has announced two new BESS projects in France and Japan, as part of the Franco-Japanese Economic Forum in Tokyo during an official visit by French President Emmanuel Macron.

The company, a subsidiary of Canadian asset manager Brookfield, is developing its first large-scale installation in Japan while expanding its storage portfolio in France.

The French project, located in Vernou-la-Celle-sur-Seine in the Seine-et-Marne department, will have a capacity of 248 MW and 496 MWh. It is expected to be the largest battery in the country and the first to connect to the 400 kV transmission network operated by RTE.

Situated near the Chesnoy substation, the system will provide frequency and voltage regulation services to the Île-de-France grid. Construction is scheduled to begin in summer 2026, with commissioning planned for 2028, subject to additional environmental studies.

This marks Neoen’s second major storage project in France, following the Breizh Big Battery (92 MW/183 MWh) in Pleyber-Christ, Brittany, which the company said is nearing completion.

Neoen said the project also reflects its ongoing industrial partnership with Japan-based Nidec, with this being the twelfth battery project the two companies have developed together. Nidec will supply the battery units, assemble them at its production facility in La Fouillouse near Saint-Étienne, and provide maintenance services for 20 years.

In parallel, Neoen is launching its first investment in Japan with the Ako Battery project in Hyogo prefecture. The facility will have a capacity of 100 MW and 400 MWh. The company is partnering with France’s Equans and Japan’s Toho, and signed a grid connection agreement with Kansai Electric Power Company (KEPCO) in January 2026. Construction is expected to begin in the coming months, with commissioning targeted for 2028.

Globally, Neoen has a battery portfolio of 2.8 GW and 8.1 GWh in operation or under construction across Australia, Germany, Finland, France, Italy, Sweden, and El Salvador. The company aims to install an additional 10 GW of capacity by 2030.

India-based EV battery manufacturer Neuron Energy plans to enter the grid-scale storage market with a 5 GWh battery energy storage system (BESS) manufacturing facility in the Indian state of Maharashtra.

From pv magazine India

Neuron Energy has announced plans to build a fully automated battery energy storage system (BESS) manufacturing facility in Talegaon, in the western Indian state of Maharashtra, marking its entry into the grid-scale storage segment.

The 7-acre facility is being developed with an investment of INR 1 billion ($10.8 million) and is designed as a robotic manufacturing plant for containerized energy storage systems. Once fully operational, it will have an annual production capacity of 5 GWh and the capability to produce up to 1,000 BESS units per year.

The modular systems are intended for deployment across solar and grid infrastructure, enabling storage of surplus energy during peak generation periods and dispatch during periods of high demand.

The company said the facility will create more than 500 direct and indirect jobs across engineering, manufacturing, system integration, installation, and technical services.

Neuron Energy said its go-to-market strategy will target solar developers, commercial and industrial (C&I) customers, and utilities, with a planned business mix of 60% domestic and 40% export markets.

The company added that it plans to expand its energy storage portfolio as it builds on its existing battery manufacturing capabilities.

With conventional renewable PPA momentum slowing, Europe’s flexibility market soared in 2025, driven by a surge in fixed-offtake agreements and BESS optimization structures. At the same time, co-located storage gained unprecedented traction, signaling a shift toward more integrated and flexible energy solutions.

From ESS News

In a record-breaking year for flexibility in Europe, nearly 12 GW/24 GWh of BESS capacity was contracted under flexibility purchase agreements (FPAs) and optimization agreements, triple the volume recorded in 2024, according to Pexapark’s Renewables Market Outlook 2026. FPAs have emerged as the backbone of BESS bankability, unlocking infrastructure-style capital and enabling rapid expansion beyond Great Britain into Germany, Italy, and the Netherlands.

Contract innovation accelerated, with tolls, floors, and financial structures such as day-ahead swaps becoming mainstream, while new buyer profiles – including traders, insurers, and hedge funds – entered the flexibility market. By contrast, traditional European PPA momentum cooled in 2025 as markets adjusted to lower capture expectations. Total disclosed contracted PPA capacity fell to 13.1 GW across 247 deals, down from 15.3 GW in 2024.
