In a significant milestone for the energy storage sector, Sineng Electric has recently achieved a major breakthrough in the long-duration energy storage field. The company’s 100 MW/400 MWh energy storage project in Inner Mongolia has successfully passed critical performance testing under China’s new national standards, GB/T 36547-2024 and GB/T 36548-2024. This accomplishment highlights Sineng Electric's leadership in the energy storage industry, particularly in integrating long-duration storage technologies to enhance grid stability and facilitate the adoption of renewable energy sources.
Overview of the Energy Storage Project
Located in Wuchuan County, Hohhot City, Inner Mongolia, the energy storage project stands as a testament to Sineng Electric’s innovation in energy storage technologies. Sineng was entrusted with providing a 5 MW centralized converter boost system solution for the project. This system is equipped with four new-generation 1250 kW centralized storage inverters connected in parallel, designed to significantly enhance the efficiency of the entire energy storage station.
This large-scale energy storage facility will play an essential role in balancing the regional grid’s energy load, integrating intermittent renewable energy sources such as wind and solar power, and ensuring continuous energy supply during peak demand periods. The high capacity and innovative technology of this project ensure it will meet the future energy needs of the region, which is a crucial step in Inner Mongolia's energy transition process.
Adherence to New National Standards
The energy storage project passed rigorous performance evaluations in line with China's newly introduced national standards, GB/T 36547-2024, and GB/T 36548-2024. These standards emphasize enhanced support for emerging battery technologies and introduce stricter requirements for energy storage systems, including grid integration functionalities such as inertia response and continuous fault ride-through (FRT). These capabilities are critical for maintaining grid stability and reliability, especially when integrating renewable energy sources that may fluctuate in output.
Sineng Electric’s participation in the development and implementation of these standards underscores its commitment to advancing the technical requirements for energy storage systems. As one of the primary contributors to the drafting of GB/T 34120-2023, GB/T 36547-2024, and other related national standards, Sineng Electric continues to focus on network-centric technologies and their application in grid-supporting energy storage solutions.
Performance Testing and Key Features
Sineng Electric’s successful execution of this project was supported by the close cooperation of its on-site service team, which ensured that all 184 low- and high-voltage ride-through scenarios and 24 continuous fault ride-through scenarios were comprehensively tested. These tests assess the system’s ability to withstand grid disturbances and ensure reliable operation during power failures, which is essential for the stability of large-scale energy storage facilities.
The successful completion of these tests not only affirms Sineng’s technical capabilities but also demonstrates the company’s ability to provide solutions that adhere to the highest industry standards. The performance of the energy storage system has garnered high praise from clients, reflecting Sineng Electric’s expertise and commitment to delivering state-of-the-art energy storage solutions.
Supporting Local Energy Transition
With the energy storage system now operational, it is expected to make a substantial contribution to the stability of the power grid in Inner Mongolia. The project is designed to optimize the integration of renewable energy into the grid, helping to reduce curtailment of wind and solar power while enhancing the region's energy security. By enabling more effective energy storage and distribution, the project will aid in the smooth transition to cleaner, more sustainable energy sources in the area.
As the project progresses, it will continue to support the local energy transition, facilitating the integration of renewable power into the national grid and contributing to the overall energy efficiency of the region.
Sineng Electric’s successful implementation of the 100 MW/400 MWh long-duration energy storage project in Inner Mongolia marks a significant achievement in the energy storage industry. By adhering to the stringent requirements of China’s new national standards, Sineng Electric has once again demonstrated its technological prowess and leadership in the field of energy storage. This breakthrough not only reinforces the company’s position as a key player in energy storage but also provides valuable insights into the future of large-scale energy storage technologies.
As the energy storage industry continues to evolve, projects like this will play an increasingly important role in shaping the future of global energy systems, ensuring the stability and efficiency of power grids while supporting the transition to a sustainable energy future.
