Project Overview
Recently, Gooree Energy successfully completed the commissioning and delivery of its energy storage system for a mining microgrid project in Nigeria. This project marks a significant milestone in Gooree’s global journey, validating the adaptability and reliability of its products under the harsh conditions of remote regions in Africa.
By deploying high-rate liquid-cooled energy storage cabinets integrated with on-site solar PV and diesel generators, the project established a multi-energy complementary microgrid. It now provides the mining area with stable, efficient, and low-carbon power, effectively addressing long-standing challenges such as unstable electricity supply, high energy consumption, and costly maintenance.
Project Scale: 1.25 MW / 1.29 MWh
System Features: Flexible response to variable loads, ensuring 24/7 stable power supply
Power Challenges and Transition Needs
For years, mining sites in Nigeria have faced severe power supply constraints due to their remote locations and complex grid conditions. Common pain points include:
Unstable power supply: Limited grid access and high diesel generator maintenance costs.
High load fluctuations: Heavy equipment startup currents causing frequent voltage drops.
High energy use and emissions: Conventional energy models incompatible with sustainable goals.
Under the dual pressures of high demand and high energy intensity, mining operations urgently require a stable, safe, and low-carbon renewable energy solution.
Gooree’s Energy Storage Solution
With deep expertise in energy storage, Gooree Energy provides full-chain R&D and integration capabilities spanning PACK design, system integration, and EMS development. For this project, Gooree delivered a high-rate energy storage solution tailored to the demanding mining load profile:
High-safety LFP battery chemistry with excellent thermal stability.
Modular liquid-cooling design with ≤3 °C temperature difference.
Smart EMS scheduling for sub-second power response.
AI-based health management algorithms enabling predictive maintenance and extended lifecycle.
System Architecture and Dispatch Logic
To handle complex loads and fluctuating energy conditions, Gooree Energy designed a multi-energy complementary system integrating Solar PV + Energy Storage + Diesel Generator + Load + EMS, achieving dynamic balance and intelligent energy coordination.
Guided by the principle of “Build on Reliability” the system combines high-safety energy storage with intelligent scheduling to ensure every kilowatt-hour is safe, efficient, and controllable.
Daytime: PV generation supplies power; energy storage performs peak shaving and valley filling.
