    Energy Storage

    Store Potential, Empower Growth, Lead the Future with Intelligence

    Energy Storage

    Energy storage is the cornerstone of the new power system. GCL ET deploys a three-pillar strategy: Utility-Scale Storage for grid security; Grid-Side Storage for system balancing; Commercial & Industrial (C&I) Storage for value creation. Through multi-scenario, large-scale, and intelligent solutions, we provide solid guarantees for stable grid operation and create sustainable low-carbon economic value for enterprises.

    • Pumped Storage

    The Jiande Pumped Storage Power Station in Zhejiang is the largest pumped storage project in East China and has been included in national and provincial energy development plans. Upon completion, it will primarily undertake peak shaving, valley filling, energy storage, frequency regulation, phase modulation, and emergency backup tasks for the East China Grid, enhancing the grid's peak regulation capacity, facilitating the integration of wind and solar power, and improving power supply quality.

    Projects

    Jiande Pumped Hydro (Zhejiang)
    Installed capacity 2,400 MW, designed annual generation capacity of 2.4 billion kWh, annual pumping power consumption of 3.2 billion kWh. It is currently the largest pumped storage power station in East China and the largest investment project in Jiande's history.

    C&I Storage

    Focusing on regions with high electricity price differentials such as the Yangtze River Delta and Pearl River Delta, we provide commercial and industrial users with integrated "Storage + Solar + Virtual Power Plant" solutions. Basic returns are achieved through peak-valley arbitrage and demand response, and projects are innovatively connected to our virtual power plant platform. This platform can open additional revenue channels for users, such as capacity compensation and frequency regulation, significantly enhancing the comprehensive return rate and energy asset value of projects.

    Projects

    Gaoyou Chuanyi Integrated Site
    13.5 MW distributed solar + 5 MWh sodium-ion storage + 7 80kW DC chargers + 9 7kW AC chargers
    Mitsubishi Electric (Guangzhou) behind-the-meter storage
    2.9 MW/15 MWh user-side storage, configured with 3 LFP battery containers and 2 PCS containers, supplying power to the entire plant via Mitsubishi Electric's 10kV switchgear.
