Key takeaways:
The Santanghu project combines 250 MW output with 1,000 MWh storage using LFP batteries across 81 units on 6 ha of land
The system is said to operate between challenging extreme temperatures of −27°C to +38°C
The Siyuanqiao project integrates 15 storage units, each with 2 compact charging stations for electric vehicles
Beijing HyperStrong Technology Co., LTD., a Chinese energy storage system (ESS) integrator and service provider, had 2 of its projects nominated as finalists of The smarter E AWARD 2025 under the Outstanding Projects category.
The first is a utility-scale ESS project at Santanghu, with a 250 MW/1,000 MWh capacity, and the second is a commercial and industrial (C&I) integrated charging and storage project located in Siyuanqiao, with a 1.5 MW/1.037 MWh capacity.
According to the company, the Santanghu ESS project uses lithium-iron-phosphate (LFP) batteries with varied power classes in a total of 81 units. Located about 1,000 m above sea level and spread over 6 ha of land, this system experiences extreme seasonal temperatures, ranging from -27°C to +38°C. This variation adds to the challenge of heat and cooling management in storage systems. HyperStrong states that this system, in combination with a renewable energy source, improves grid stability.
As part of the integrated charging and storage project in Siyuanqiao, 15 storage units with 2 compact charging stations were installed. According to the company, these are capable of charging up to 30 electric vehicles simultaneously. It adds that this project was deployed to ease the load on an existing distributed 10 kV system.
