In a landmark achievement for global energy innovation, the 10MWh grid-forming energy storage project at Huayou Cobalt’s Lukuni hydrometallurgical plant in the Democratic Republic of Congo (DRC) has officially commenced operations. This milestone marks the first international collaboration between Jiangsu Huayou Energy and EAST Advanced Energy (formerly known as EasyTech), showcasing a cutting-edge solution tailored for off-grid industrial applications.
The project establishes an integrated smart microgrid combining solar, storage, and diesel generation—enabling millisecond-level fault response and precise coordination among power sources, loads, and storage systems. By maximizing local renewable energy consumption, it significantly reduces reliance on diesel fuel, driving down operational costs and advancing sustainable mining practices.
Solving Off-Grid Power Challenges with Smart Energy Integration
One of the most pressing challenges in remote mining operations is the absence of reliable grid infrastructure. At the Lukuni site, there is no access to municipal electricity, leaving operations entirely dependent on diesel generators. This not only inflates energy costs but also increases carbon emissions and maintenance complexity.
To address this, the project implements a grid-forming energy storage system that synchronizes with existing 10kV diesel generators and a 3MW photovoltaic (PV) array. Unlike conventional "grid-following" systems, grid-forming technology can autonomously regulate voltage and frequency, effectively acting as a virtual power plant to stabilize the entire microgrid.

During daylight hours, solar power takes priority. Excess energy charges the battery system while smoothing out PV output fluctuations. At night, the 10MWh lithium-ion battery system discharges for over 14 hours, drastically reducing diesel generator runtime. This intelligent load management is projected to save over $2.33 million annually in diesel fuel costs alone.
Seamless Power Switching for Uninterrupted Operations
Continuous power supply is non-negotiable in mining environments where even brief outages can disrupt critical processes and compromise safety. To ensure uninterrupted operation, the project deploys EAST’s proprietary station-level EMS (Energy Management System).
This intelligent control platform enables seamless switching between different power sources—solar, battery, and diesel—without any power interruption. Whether transitioning from solar to storage or engaging backup generators during peak demand, the system maintains stable output through advanced synchronization algorithms.
Such capabilities are vital for protecting sensitive equipment and maintaining production continuity in harsh industrial conditions. The EMS also provides real-time monitoring, predictive analytics, and remote diagnostics, empowering operators with full visibility and control over their energy ecosystem.
Custom Engineering for Harsh Environments
Deploying high-tech energy systems in Central Africa presents unique logistical and environmental challenges—from extreme temperatures and humidity to limited local technical expertise and supply chain constraints.
EAST and Huayou’s engineering teams conducted a comprehensive assessment of the site’s energy profile and operational needs. They designed a fully customized grid-forming solution optimized for durability, efficiency, and ease of maintenance.
Throughout construction, delivery and commissioning engineers worked on-site under demanding conditions, ensuring every phase—from equipment installation to system debugging and safety verification—was executed with precision. Their meticulous approach ensured timely project completion and earned high praise from stakeholders.
This hands-on, localized execution model reflects EAST’s broader strategy: combining global technological leadership with on-the-ground support to deliver turnkey solutions anywhere in the world.

Frequently Asked Questions (FAQ)
Q: What is a grid-forming energy storage system?
A: Unlike traditional grid-following systems that rely on external voltage and frequency signals, grid-forming systems can generate their own stable AC waveform. This allows them to operate independently or as the primary stabilizer in microgrids—especially useful in off-grid or weak-grid environments.
Q: How does this project reduce carbon emissions?
A: By displacing diesel generator usage with clean solar energy stored in batteries, the system significantly cuts fossil fuel consumption. Over a year, this translates into thousands of tons of avoided CO₂ emissions, contributing to corporate sustainability goals.
Q: Can this solution be scaled for larger industrial sites?
A: Absolutely. The modular design of both the battery system and control architecture allows seamless scalability—from 10MWh installations like Lukuni to hundreds of megawatt-hours for larger mining complexes or industrial zones.
Q: Why is energy management software critical in hybrid systems?
A: In multi-source environments (solar + storage + diesel), real-time optimization is essential. The EMS ensures optimal dispatch of each resource based on load demand, weather forecasts, and cost factors—maximizing efficiency and economic returns.
Q: Is this technology suitable for other regions with unreliable grids?
A: Yes. Grid-forming storage is ideal for remote areas, island grids, or regions experiencing frequent blackouts. It enhances grid stability, supports renewable integration, and provides backup resilience—making it a key enabler of energy access and decarbonization globally.
