Astrol Electronic AG (hereinafter referred to as Astrol), a subsidiary of Sun.King Technology, is proud to announce a new milestone in the field of large-scale thermal energy storage. After years of close collaboration and joint development with the customer, Astrol has received the first order for its newly developed medium-voltage distribution platform.

This customized turnkey solution integrates the complete set of electrical equipment required for operating a thermal energy storage system. It plays a critical role in connecting megawatt-scale charging power to the grid and features advanced protection and monitoring functions that are essential for ensuring the safety of both the storage system and the power supply network.

Thermal energy storage systems are expected to play an increasingly vital role in the future of the power grid. As renewable energy generation becomes more decentralized, efficient energy storage has become indispensable for balancing generation fluctuations. By combining its expertise in thermal energy storage technology with state-of-the-art power switching technology, Astrol enables the stable 24-hour utilization of renewable energy — delivering both direct heat output and convertible electrical energy.

Astrol’s newly developed medium-voltage distribution platform is designed based on the concept of standardized system components across voltage, current, and power levels, a principle the company has successfully implemented in multiple fields in recent years. With this modular and scalable design, identical components can be adapted to various projects worldwide, regardless of differences in project scale, environmental conditions, or regulatory requirements.

This design philosophy aligns perfectly with the customer’s key demand for a globally scalable and deployable solution. Astrol is now preparing for subsequent orders and will continue to leverage opportunities in the rapidly growing and high-potential thermal energy storage sector, further strengthening its position in the global energy transition.
