CORUN has taken a significant step forward in its energy storage deployment, recently securing approval to invest in energy storage projects totaling 1.2GW/3.2GWh across four provincial regions: Hebei, Shandong, Inner Mongolia, and Guangdong. These projects are being advanced through the company’s energy storage industry fund model. To date, approvals have been secured for eight standalone energy storage stations, with construction scheduled to begin in the third to fourth quarter of 2025.
The regional distribution of these projects highlights their targeted strategic roles. The 400MW/1000MWh project in Hebei is designed to support peak shaving for the North China Power Grid. In Shandong, a 400MW/800MWh facility will enhance renewable energy integration. The 300MW/1200MWh project in Inner Mongolia focuses on reducing curtailment of wind and solar power. Meanwhile, the 100MW/200MWh project in Guangdong will serve the load center, ensuring power balance and contributing to a nationwide storage network spanning both northern and southern China.
CORUN has a diversified business portfolio that includes HEV battery systems, nickel-based battery materials, lithium carbonate resource development, and consumer battery production. In recent years, the company has steadily increased its investment in standalone energy storage projects. Its Baoding storage system production base officially commenced operations at the end of June 2025, with an annual capacity of 2GWh in integrated energy storage systems. Upstream, CORUN’s Tong’an lithium mining project now achieves over 60% self-sufficiency in lithium carbonate production, with a total capacity of 30,000 tons per year.
According to its strategic plan, CORUN aims to invest in 4.7GWh of energy storage projects via its industry fund in 2025, with projected storage-related revenue reaching RMB 2.015 billion, positioning energy storage as its largest business segment. However, CORUN’s storage business is still in the early stages of scaled deployment. While it benefits from differentiated technology routes and strong supply chain synergy, challenges remain in market competition, cost control, and financial sustainability. The 2025–2027 period will be a critical window for the company to scale production and validate its business model—ultimately determining its standing in the energy storage sector.
