Sibanye-Stillwater

Sibanye-Stillwater, a multinational mining and metals processor, needed to improve energy efficiency of mine ventilation systems at South African gold mines. Large surface ventilation fans require continuous operation for safety, consuming massive amounts of energy.

Energy Drive deployed and optimized variable-frequency drives (VFDs) on large surface ventilation fans, using PowerFlex technology to dynamically adjust fan speeds based on actual ventilation demand rather than running at constant speed.

Delivered significant energy savings and carbon reduction for Sibanye's gold mines in South Africa. Reduced energy consumption while maintaining required ventilation standards. Helped clients achieve sustainability targets at net savings.

• VFD optimization of mine ventilation fans delivers both energy savings and carbon reduction
• Sustainability investments in mining can achieve net savings rather than net costs
• Demand-based ventilation control is safer and more efficient than constant-speed operation
