Renewable energy for mining
Why mines are moving to renewable energy
In the ever-evolving landscape of Africa's mining sector, the shift towards renewable energy solutions is not just a trend, but a strategic necessity.
PAN African Resources
In 2021, PAN African Resources became the first mining company in South Africa to establish a large-scale PV solar plant. Developed and constructed by JUWI, this grid-connected solar plant provides 10 MW of clean energy to the Elikhulu Tailings Retreatment Plant at the Evander mine. Not only does JUWI oversee the operations and maintenance, but we are also committed to training PAN African Resources employees for eventual project management. PAN African Resources has ambitious sustainability goals and the JUWI construction team is already hard at work on a second 8.75 MW solar plant for their Barberton Mine.
-
Supplies 30% of the treatment plant's annual power requirements.
-
Annual cost saving of $1.7 million.
-
Reduces Scope 1 GHG emissions by 26,000 t/y CO2 equivalent.
-
Created 100 jobs during construction.
Sukari Gold Mine
The Sukari Gold Mine near the Red Sea in Egypt exemplifies the integration of solar PV and energy storage to combat climate change while offering cost savings and managing intermittency. Located in a remote desert area, the mine historically relied on diesel and heavy fuel oil for power. JUWI designed, engineered, and constructed a 36 MW solar power plant, integrated with a 7.5 MW Battery Energy Storage System. JUWI continues to manage the plant as the Operations and Maintenance service provider.
-
Reduction in diesel consumption by 22 million liters per year.
-
Annual cost savings of $20 million.
-
Reduction in Scope 1 GHG emissions by 60,000 t/y CO2 equivalent.
-
Significant reduction in exposure to fuel price volatility.
