Huawei Showcases Intelligent Solar Storage Solutions at ESIE 2025 to Shape the Future of Energy Integration

Fusion of Light Storage: Building a Smart Future | Huawei Shines at ESIE 2025 with Intelligent Light Storage Solutions!

On April 10, the 13th International Energy Storage Summit and Exhibition (ESIE 2025) was successfully inaugurated at the Beijing Capital International Convention Center. This summit gathered leading global energy storage brands and industry leaders to discuss the trends and challenges in energy storage development. As a global leader in digital energy products and solutions, Huawei Digital Energy showcased its latest achievements in the field of energy storage, including intelligent light storage solutions for power stations and commercial industries.

During the exhibition, Huawei was invited to participate in a high-level forum and a forum on grid-forming energy storage technology, where it shared its latest technological solutions and practical applications. Huawei also received several awards at the 9th International Energy Storage Innovation Competition.

With the ongoing pursuit of global carbon neutrality, a new power system has ushered in the era of solar, wind, and storage integration. Grid-forming energy storage has become a necessity throughout the entire process of power generation, transmission, distribution, and consumption, enabling the stable operation of new power systems.

Zhang Guanghui, Head of Huawei's Digital Energy Intelligent Solar Storage Expansion Department in China, addressed the forum, stating that despite the rapid development of the light storage industry, challenges such as low usable capacity, poor constant power characteristics, high electricity costs, and significant safety concerns still remain. In response, Huawei has launched an intelligent solar and wind storage generator solution centered around "solar storage grid cloud," offering four key benefits: comprehensive architecture safety, all-scenario grid formation, full lifecycle economics, and end-to-end digitalization. This solution aims to transform solar power generation from merely following the grid to actively supporting it, enhancing the integration of renewable energy through three stability reconstruction technologies: voltage, frequency, and power angle.

In the Red Sea area of Saudi Arabia, Huawei assisted its client in establishing the world's largest solar storage microgrid project, achieving independent and stable grid formation to provide 100% renewable energy power supply for millions of visitors in the Red Sea New City. In Tibet, Huawei collaborated with the Tibet Development Investment Group to deploy a string-based grid-forming energy storage system, creating the world's first innovative demonstration of grid-forming energy storage in ultra-high altitude, ultra-low temperature, and ultra-weak grid environments, providing a replicable technical path and empirical experience for renewable energy grid connection in extreme environments.

The energy storage project at the Golmud Green Development Multi-Energy Complementary Power Station in Qinghai successfully verified Huawei's intelligent solar and wind storage generator's grid-forming performance and its ability to operate in coordination with various power sources and multiple parallel connections. With the advancement of carbon neutrality goals and the rapid development of renewable energy, several policies have begun to encourage the development of grid-forming energy storage, which is becoming a key technology for supporting the stable operation of the grid and gaining recognition in the industry.

At the grid-forming energy storage technology forum, Yang Zhi, Senior Product Manager of Huawei Digital Energy's Energy Storage Solutions in China, stated that Huawei, through years of expertise in power electronics and grid-friendly technology, has innovatively proposed a smart string-based grid-forming energy storage technology system, leveraging self-developed high-performance power devices, string-level dual architecture, and intelligent grid control algorithms. This system achieves stable and reliable grid formation across all scenarios, operational conditions, and lifecycles.

Yang emphasized that the solution has completed validation from modeling and simulation to empirical testing, successfully demonstrating effective results across various projects ranging from MWh to multiple hundred MWh levels, receiving high recognition from authoritative industry organizations and users. In the future, Huawei will steadily advance the smart string-based grid-forming energy storage from demonstration validation to large-scale application, ensuring stable and reliable support for new power systems and accelerating the transition of renewable energy into the primary energy source, thereby contributing to the realization of carbon neutrality goals.

Huawei has also received numerous awards at the 9th International Energy Storage Innovation Competition. Notably, the "Tibet Development Investment Group's Ali Gaze 30MW Solar (with Energy Storage) Project" won the "2025 Energy Storage Application Innovation Model TOP 10" award and was recognized as an excellent project in the application innovation category. In the technology innovation group, the "Intelligent String-Based Grid-Forming Energy Storage System Based on Voltage Source PCS Multiple Machine Parallel Technology" also received accolades for its excellence, further demonstrating Huawei's industry strength.

Driving by policies, commercial interests, and technological advancements, integrated energy solutions for parks are gradually maturing. Major reforms in distributed solar grid integration and market pricing for electricity transactions are anticipated. On the commercial side, the cost of solar storage power generation is entering a parity era. Moreover, technical innovations in solar storage integration and grid-forming technologies are establishing integrated energy solutions as the best practice for addressing energy challenges in parks.

At the exhibition, Huawei introduced its integrated energy solution for commercial and industrial users, attracting significant interest from professional audiences. This solution transitions from pure solar to solar-storage integration, enhancing the green electricity absorption ratio and optimizing the full-cycle benefits of commercial solar storage. On the grid side, it assures better power quality, higher reliability, and stronger load capacity, while supporting high-quality electricity for enterprises through all-scenario grid formation. The load side, utilizing "solar-storage charging + grid-forming technology," mitigates the impact of megawatt-level ultra-rapid charging on the grid and increases overall returns. The first wind-liquid intelligent cooling energy storage cabinet offers enhanced efficiency, long-term reliability, and a lifecycle return increase of over 10%. Additionally, the system-level active safety solution ensures the long-term sustainable development of park energy usage. Furthermore, Huawei collaborates with partners to provide a comprehensive energy/virtual power plant management system for parks.

The integrated energy solution for commercial and industrial users aims to achieve ultimate safety and long-term returns, digitally empowering low-carbon transitions in parks. Looking ahead, Huawei Digital Energy will continue to focus on research and development innovations, working with customers and partners to build a new power system dominated by renewable energy, promoting solar energy as a primary power source and enabling green electricity to benefit various industries.
