While Chinese new energy companies are still searching for a way out of the barriers to entry in the European market, a battery giant with nearly 40 years of history has already produced locally.

Going back to November 2025, Tianneng International Co., Limited quietly established a European office in the Netherlands, while the industry's focus was still on channel development. Just a few months later, this company that emerged from Changxing, Zhejiang, showed its trump card by moving its manufacturing directly to the heartland of Europe. Recently, Tianneng International Co., Limited signed a letter of intent to cooperate with ELQ Group in Poland, and the two parties will jointly build an energy storage system assembly factory in Czestohova, Poland. This not only marks the official landing of Tianneng International Co., Limited's first production-oriented energy storage project in Europe, but also signifies that China's energy storage capabilities are deeply embedded in the local industrial chain of the European Union.

Joint venture breakthrough

This cooperation is not simply about capacity output, but a deep binding of interests. According to the agreement, both parties will establish a joint venture company, with Tianneng International Co., Limited holding approximately 50% of the shares, Polish ELQ Group holding 45%, and the remaining 5% held by local enterprise KM Grom. The diversification of equity structure ensures a balance between technology and market. The project will rely on the existing factory area of ELQ Group for renovation, and is expected to be completed and put into operation in the first quarter of 2027. This light asset start-up model not only avoids the long-term risks of building new factories, but also quickly gains recognition from the local industry.

Capacity ramp-up

The capacity release plan appears pragmatic and ambitious. In the initial stage, the factory will achieve an assembly and debugging scale of 100MWh, and the supporting production capacity will reach 1GWh in the first year of operation. According to the plan, the overall production capacity will be increased to 5GWh within three years of operation. This volume is sufficient to cover the energy storage system supply in Poland and the entire European market. With the phased advancement of the production line, Tianneng International Co., Limited will effectively shorten the supply chain in the European region, significantly reduce logistics cycles and overall costs, and respond to the urgent needs of the power grid side and industrial and commercial customers nearby.

technology implementation

In terms of division of labor, Tianneng International Co., Limited will provide a complete set of energy storage technologies, production processes, and quality control standards, and steadily supply core components; ELQ Group is responsible for the construction of factory infrastructure, production management, and sales channel coordination. As Dr. Marcin Soltisiak, President of ELQ Group, has stated, Poland's energy transformation cannot solely rely on imported complete sets of equipment. Localized assembly can help improve the industrial chain and enhance regional energy security capabilities. This coincides with the trend of localized manufacturing advocated by the European Union in recent years.

For Tianneng, founded in 1986, its vast system of over 160 subsidiaries and 18 production bases is now being revitalized through this Polish factory. Liu Jian, President of Tianneng International Co., Limited, believes that combining global R&D and manufacturing experience with local resources can not only export mature technology, but also create long-term stable cooperative relationships.keywords:New energy information network
