Project Overview：

The mine previously relied solely on 18 diesel generators with a high energy cost of $0.44/kWh, exacerbated by rising fuel costs and logistics/labor expenses. Grid power ($0.14/kWh) offered lower rates but unreliable supply.

The project deployed a smart microgrid integrating solar PV, battery storage, diesel backup, and grid connectivity, prioritizing solar energy for daytime use with excess stored for nighttime/inclement weather while retaining diesel as backup.
