Renewables opening doors for innovative energy solutions in mining

The year 2019 was the turning point for renewable energy projects at remote mines. More than a dozen projects were commissioned or announced. Mining companies have adopted solar and wind power to reduce their energy cost and carbon footprint in a rather lengthy process. In the last years, successful flagship projects have removed concerns about production loss and independent power ...

New THEnergy-Voltalia report: Renewables for mining in Africa enter the next stage – focus shifts to cost optimization

In the last few years, more and more mining companies in Africa have adopted wind and solar systems to reduce their energy costs at remote off-grid mines. In this first phase, the initial focus was on the integration capabilities as miners were afraid that adding intermittent renewables such as solar and wind could affect the reliability of power supply and ...

THEnergy analysis: Solar-diesel and Wind-diesel Microgrids for Off-grid Mines Gain Momentum – New Projects Expected

Iamgold has announced it is adding a new 12.5 MW solar PV plant to its Essakane gold mine in Burkina Faso. The Canadian company has signed a power purchase agreement (PPA) with the French independent power producer (IPP) EREN for an initial period of 15 years. The multinational Wärtsilä headquartered in Finland will integrate and build the solar plant. Another ...

PFISTERER/THEnergy study: Mobile solar/wind and storage solutions for reducing diesel consumption in the mining industry

Due to the remote locations, power generation for mineral exploration camps is particularly expensive. Typically, power is generated by gensets, and the diesel fuel needs to be transported over long distances by truck or sometimes even by helicopter. The cost of solar and wind energy has declined dramatically over the last decade. Renewable energy could potentially contribute substantial cost savings ...

Analysis: Momentum for solar-diesel hybrid microgrids in the Zambian mining industry

In recent years, an ongoing drought has caused a severe power crisis in Zambia. The new analysis “Power crisis and consequences for solar energy in the Zambian mining sector” from the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, Eschborn/Germany, in its role as facilitator of the Project Development Programme (PDP) and the consulting company THEnergy, Munich/Germany, shows that the framework ...

Ripasso/THEnergy study: Renewables for mining go baseload with a hybrid fuel-solar solution

The study “A hybrid solution with concentrated solar power (CSP) and fuel for baseload mining operations” analyses the fit of Stirling Hybrid solutions for the mining industry. The Stirling engine based solution combines in an integrated system solar with gas or diesel as an energy source. The CSP-solar component relies on making it particularly appealing for extremely sunny regions. In ...
