SINEXCEL's Pioneering Efforts in Grid-Forming Energy Storage Standards Enhance Industry Development

Advancing Energy Storage Standards: SINEXCEL's Impact

SINEXCEL, a renowned entity in the modular energy storage sector, has made significant strides in the development of energy storage technology standards. On July 2, 2025, they announced their critical involvement in drafting two essential technical specifications aimed at enhancing grid-forming energy storage systems in China. These standards were initiated by the Shenzhen Power Supply Bureau and co-developed with reputable academic institutions such as Tsinghua Shenzhen International Graduate School and Harbin Institute of Technology (Shenzhen).

Recognizing the growing demand for reliable energy storage solutions, the first standard — T/SPSTS 035-2024 — delineates technical specifications for grid-forming electrochemical energy storage systems. This document offers vital definitions concerning the performance and functionality that such systems must meet, paving the way for clear technical guidance crucial for effective planning and deployment in densely populated urban areas, including Shenzhen.

Furthermore, the second specification — T/SPSTS 036-2024 — presents crucial guidelines for black start technology related to grid-forming systems. This standard outlines key principles and operational protocols necessary for the recovery of grid systems following extensive outages or failures, ensuring that communities can restore power swiftly and efficiently.

These groundbreaking standards are not merely theoretical but build on SINEXCEL's practical achievements, notably the successful deployment of the world’s first grid-forming energy storage system at a low-altitude logistics hub. This initiative stands as a significant milestone under the Guangdong province's principal research and development initiative titled "Research on Core Technologies and Equipment of Grid-Forming Energy Storage Inverters."

The comprehensive nature of these standards offers a framework that encompasses the entire lifecycle of grid-forming storage systems — from their design and manufacturing to integration into the grid and ongoing operational functionality. SINEXCEL, leveraging its rich experience and innovative technologies, has crafted a robust portfolio of high-voltage grid-forming storage solutions. These include advanced control algorithms, various high-power inverter topologies, and fault ride-through support features.

Furthermore, these solutions have shown impressive adaptability across diverse scenarios, whether in strong or weak grid conditions or even off-grid settings. Such versatility contributes essential insights for shaping the new standards, which are increasingly vital as energy demands rise across urban centers.

SINEXCEL's involvement in the establishment of these standards highlights its enduring commitment to fostering innovation and leadership in the field of grid-forming storage technology. As the company looks to the future, it is determined to continue driving collaborative research and development initiatives that advance the implementation of these standards in the energy sector.

In addition to the academic collaborations, SINEXCEL partners with industry leaders, including EVE Energy and Schneider Electric, to propel energy autonomy and sustainability on global scales. Founded in 2007, SINEXCEL has successfully installed approximately 12 GW of energy storage capacity, with a significant installation of 140,000 EV chargers and nearly 20 million amperes of AHF deployments, setting a benchmark for others in the industry.

In closing, SINEXCEL's strategic role in the creation of these energy storage standards marks a pivotal moment in the transition towards sustainable energy solutions. With a vision that extends beyond mere compliance to exceed global standards, SINEXCEL is dedicated to creating a more resilient and sustainable energy future for all.
