Chinese battery manufacturer CORNEX New Energy (楚能新能源) and Denmark-based KK Group have signed a strategic agreement covering 5 gigawatt-hours of energy-storage capacity for the European market.
The agreement expands cooperation between the two companies from product supply to a broader range of services, including system design, equipment delivery, operations and maintenance, and battery recycling.
CORNEX said the partnership is intended to create a full-lifecycle energy-storage service model for European customers. Financial terms, specific project locations and a detailed delivery schedule were not disclosed.
The agreement follows an earlier cooperation arrangement signed by the companies during The smarter E Europe 2026, a major renewable-energy and storage industry event. The latest deal provides a larger framework for their activities in Europe.
KK Group is part of the portfolio of A.P. Moller Holding (A.P.穆勒控股). The Danish industrial group operates across areas including power conversion, cooling and engineering solutions for the renewable-energy sector.
The partnership comes as European countries accelerate the deployment of battery storage to support increasing amounts of wind and solar power. Because renewable output changes with weather conditions, storage facilities can absorb surplus electricity and release it when demand rises or renewable generation declines.
Battery systems can also provide frequency regulation, capacity support and other services required to maintain grid stability. Demand for these capabilities is increasing as Europe reduces its reliance on conventional fossil-fuel generation.
For Chinese battery manufacturers, the European market offers growth opportunities but also imposes demanding requirements. Suppliers must address product safety, grid compatibility, cybersecurity, environmental standards and battery traceability. European regulations are also placing greater emphasis on recycling and lifecycle carbon emissions.
CORNEX’s inclusion of operations, maintenance and recycling in the agreement suggests that the company is seeking to compete through integrated services rather than battery-cell prices alone.
This reflects a broader change in the globalization of China’s energy-storage industry. Manufacturers that initially expanded through equipment exports are increasingly building local engineering teams, service networks and partnerships with European developers and industrial groups.
The announced 5 GWh figure represents the overall framework of the cooperation and should not be interpreted as capacity that has already been delivered. Actual deployment will depend on individual customer contracts, project approvals and grid-connection schedules.
If implemented as planned, the partnership could strengthen CORNEX’s position in Europe while giving KK Group access to large-scale battery technology and manufacturing capacity.
