On April 10, 2025, the ESIE2025 Energy Storage Summit & Expo, one of the most prestigious global events in the energy storage industry, opened grandly at the Beijing Capital International Exhibition Center. As a leading player in China’s energy storage sector, Zhiguang Energy Storage showcased its latest grid-forming intelligent energy storage systems and multi-scenario solutions, highlighting how technological innovation is key to meeting the urgent demands of a fully market-driven renewable energy landscape.
At the summit, Mr. Fu Jinjian, General Manager of Guangzhou Zhiguang Energy Storage Technology Co., Ltd., delivered a keynote titled "The Value of Energy Storage in the Era of Market-Based Renewables."
With the official release of the National Development and Reform Commission’s 2025 directive on deepening electricity pricing reform, renewable energy prices are now fully market-determined. This shift marks a new era in which energy storage is no longer just a regulatory requirement, but a core economic asset, essential for smoothing renewable fluctuations and enhancing grid flexibility.
Under the new policy, renewable operators must bear system balancing costs, accelerating the need for multi-energy integration—including wind, solar, hydro, thermal, and storage. As a result, new-type energy storage is becoming the cornerstone of grid security and supply-demand equilibrium.
Zhiguang Energy Storage is actively advancing the R&D and deployment of grid-forming energy storage systems, breaking away from the passive response paradigm and enabling active grid participation and autonomous power trading.
The Grid-Forming Energy Storage System was the highlight of Zhiguang’s exhibit, offering three key competitive advantages:
Active Grid Stabilization
Mimicking traditional synchronous generators, the system dynamically regulates voltage and frequency to provide inertia-like response. It can rapidly support the grid during renewable output drops or faults, significantly enhancing grid resilience.
AI-Powered Energy Trading
Integrated with an AI-driven Energy Butler system, it conducts real-time analysis of electricity price fluctuations and load forecasts to autonomously optimize charging and discharging—maximizing station revenue.
Multi-Scenario Compatibility
Adaptable to commercial parks, zero-carbon microgrids, and shore power systems, the solution supports PV + Storage + EV charging integration and virtual power plant aggregation, fulfilling diverse needs across supply, grid, and demand sides.
Prior to the expo, Zhiguang signed a two-year strategic agreement with Hithium for 15GWh of battery cell supply, securing a robust supply chain for large-scale project delivery. The company also unveiled its "Storage + AI + Scenario-Driven" strategy, leveraging digital tools to optimize lifecycle costs and improve economic returns.
With renewable integration becoming fully market-based, storage value is shifting from policy-driven mandates to market-oriented returns. Zhiguang’s grid-forming system delivers closed-loop value through:
Ancillary Services Revenue
Participation in frequency regulation, spinning reserve, and capacity markets yields both power and capacity compensation.
Time-of-Use Arbitrage
Smart scheduling based on real-time pricing maximizes arbitrage opportunities across peak and off-peak periods.
System Synergy & Efficiency
In zero-carbon parks and hybrid renewable systems, integration with distributed PV and hydrogen boosts overall energy utilization.
As China's unified spot electricity market rapidly advances, storage players must innovate to manage price volatility. Zhiguang’s “intelligent grid-forming + scenario integration” model offers a clear path beyond cutthroat price competition—positioning the company to evolve from a product manufacturer to a holistic energy system service provider.
Through the successful deployment of its grid-forming cascaded high-voltage demonstration projects, Zhiguang has proven that storage is not only the “stabilizer” of the future grid but also the “accelerator” of the global energy transition.
Looking ahead, Zhiguang Energy Storage will continue scaling the industrial deployment of its grid-forming HV systems, contributing its strength to the construction of a new power system with renewables at its core.
