Industrial Hybrid BESS
Micro-Grid BESS
Background
Located on the outskirts of Harare, Zimbabwe, this quarry operation previously relied entirely on a 600kVA diesel generator to power its large stone-cutting machinery. The remote location and lack of grid connection created significant operational challenges that impacted both productivity and profitability.
-
When two large machines started simultaneously, the combined high-impact load overwhelmed the diesel generator, causing complete power outages across the quarry.
-
The diesel generator couldn't respond promptly to load surges, leading to power instability and preventing operation at optimal efficiency.
-
This inefficiency resulted in significantly higher fuel consumption, severe carbon buildup, and increased maintenance costs.
-
The high noise levels and pollution from the 600kVA diesel generator created an intolerable working environment for workers.
Turnkey Solution
Masspoint designed and implemented a comprehensive micro-grid power system specifically engineered for the quarry's demanding operational requirements and remote location.
The solution prioritizes green solar energy with the energy storage system acting as the power management center and the diesel generator transitioning to a backup role. An advanced energy management system continuously monitors and optimizes the entire power supply operation.
This innovative approach ensures reliable power for high-impact loads while maximizing the use of renewable energy and minimizing diesel consumption.
