Project Overview
Project Background
An LVK 5MWh heavy-duty BESS container with 500kW STS and 3MWp PV powering a remote Nigerian gold mine's 24-hour crushing and excavation operations.
Customer Needs
The mine is situated in a remote area without grid access, yet heavy-duty crushers and excavation equipment require continuous 24-hour operation. Long-distance diesel transport is costly. Furthermore, the startup and shutdown of heavy equipment generate massive current surges; these frequently caused the diesel generators to trip due to instantaneous overload, resulting in unexpected production shutdowns across the entire mine.
Application Focus
Solar-Storage-Diesel Off-Grid Microgrid
Solution Design
Integrated ESS Design For Site Operations
Deployment of an LVK 5MWh modular heavy-duty energy storage container, featuring an optional 500kW STS (Static Transfer System) at the core power distribution output. Coupled with the EMS scheduling platform, the high-response battery system serves as the core dynamic regulator for the mine's microgrid.
