On July 7, 2025, HyperStrong, a leading China-based energy storage system (ESS) integrator and solution provider, entered into a strategic partnership agreement with Repono AB, a key European developer specializing in large-scale energy storage infrastructure. The collaboration is focused on delivering 1.4 GWh of grid-scale battery energy storage systems (BESS) across Europe by the year 2027. This strategic move underscores the growing emphasis on grid flexibility, decarbonization, and the critical role of storage systems in Europe’s evolving energy landscape.

The partnership brings together complementary strengths from both organizations. Repono AB will leverage its expertise in end-to-end project development, encompassing site selection and acquisition, regulatory permitting, environmental compliance, and grid interconnection. These competencies form the foundation for technically robust, financially viable, and regulatory-compliant energy infrastructure projects. Repono's in-depth understanding of local market dynamics and its track record in securing complex approvals position it as a key enabler for accelerating project execution across multiple European jurisdictions.

HyperStrong will serve as the technology and integration partner for the collaboration. The company will deliver comprehensive BESS integration services that include engineering design, component procurement, system assembly, and turnkey deployment. Additionally, HyperStrong will oversee long-term operational support, including system commissioning, performance optimization, routine maintenance, and lifecycle management. This ensures high reliability, safety, and maximum system availability throughout the life of each project, while also providing investors and stakeholders with confidence in long-term asset performance.

The collaboration is strategically aligned with broader European Union energy objectives, including the expansion of renewable energy, energy storage, and the reduction of dependence on fossil fuels. By deploying scalable, high-capacity battery storage systems, the partnership will help support grid stability and flexibility, which are essential for managing the variability of renewable energy sources such as wind and solar. These systems will enable demand shifting, peak shaving, frequency regulation, and enhanced energy security—critical components of a resilient and future-ready energy infrastructure.

A core component of the agreement is the establishment of a joint planning framework. Both HyperStrong and Repono will engage in regular technical and commercial reviews of their development pipeline, with the aim of ensuring alignment on engineering specifications, financial planning, delivery timelines, and compliance with evolving regulatory requirements. This structured collaboration will streamline execution, improve project risk management, and enable efficient scaling across multiple regions.

In addition to enabling clean energy deployment, the partnership supports Europe's ambition to build a resilient, competitive energy ecosystem by promoting local value chains, encouraging advanced manufacturing, and fostering skilled employment. The agreement also reflects both companies’ commitment to sustainability, innovation, and long-term growth.

HyperStrong and Repono are well-positioned to play a significant role in Europe's grid-scale energy storage expansion. Their joint approach sets a precedent for future international collaborations focused on building clean, secure, and intelligent energy systems that support the region’s climate goals and industrial competitiveness.
