In the windswept plains of Zhangbei in Hebei Province, Hoymiles recently embarked on a journey to harness the wind power, helping connect a landmark 150 MW/300 MWh energy storage station to the grid as part of a 1 GW wind power project. This breakthrough not only enhances local grid flexibility but also drives the region’s clean energy transition forward.

Story

Located at an altitude between 1,400 and 1,600 meters, Zhangbei County is known for its harsh, dry climate, extreme cold, and frequent sandstorms, making it a challenging environment for renewable energy operations. Despite its abundant wind resources, the variability of wind and solar energy posed a major challenge to grid stability and energy delivery.

To fully leverage the renewable potential and stabilize the energy output, local stakeholders needed an energy storage solution capable of peak shaving, frequency regulation, and smoothing the fluctuating generation patterns. The goal was clear: support grid operations and enhance the large-scale integration of renewables into the energy mix.

Solution

Hoymiles answered the call with its cutting-edge HoyPrime all-liquid-cooled energy storage solution. At the heart of the project are multiple 3.44 MW/6.88 MWh storage units, paired with Hoymiles’ HIM3450MV all-in-one liquid cooling PCS.

 

Specifically, the system offers:

 

  • HoyPrime fully liquidcooling energy storage solution for efficient thermal management.
  • High-altitude and extreme weather resilience, operating in temperatures from -35°C to 60°C.
  • Exceptional performance under day-night temperature fluctuations, with minimalIGBT temperature difference of just 2°C to enhance reliability and lifespan.
  • IP65 protection & C5 corrosion resistance:Engineered to withstand harsh conditions, such as extreme temperatures and sandstorms.
  • Fast-response, millisecond-level grid adaptationfor seamless renewable integration.
  • Modular design for space-saving integration and easy scalability:Compared to traditional systems, it saves more than 20% of land area for the same capacity setup. The system is also easily expandable to meet future capacity needs.
  • Safety prioritized at every level: The HoyPrime containerized battery incorporatesmulti-layer insulation, four-stage short-circuit protection (from cell to combiner level), and a triple-layer firefighting system featuring PACK-level, container-level, and sprinkler protections to ensure operational security.

Success

Thanks to Hoymiles’ high-performance, intelligent storage solutions, the Zhangbei wind-storage project now plays a critical role in balancing supply and demand, enabling greater penetration of renewable energy into the grid.

Beyond improving local grid stability, the project demonstrates a sustainable model for large-scale renewable energy deployment in challenging environments.

Hoymiles’ commitment to innovation and reliability continues to empower communities to embrace green energy. As the winds of Zhangbei keep lighting up new horizons, Hoymiles’ pioneering energy storage technologies will bring the vision of “Open Energy for All” closer to reality, energizing the global transition to a greener future.
