Many mines are located in remote sites that are not grid-connected. Electricity is often produced by diesel gensets. Driven by high fuel-transporation costs, the price for electricity generation is normally high. Renewable energy is an optimal add-on to diesel-gensets and can generated considerable fuel- and total electricity cost-savings. The objective of this platform is to communicate how mining companies are already applying renewable energy (Solar & Wind project database) and to give some background information about the topic. Regularly, reports and white papers are published for further insights.
There is quite a number of factors on both sides that have lead in the last years to a better fit of renewable energy and the mining industry. Many experts expect a boom of renewable energy applications at remote mines in the near future (see section developments).
Mining companies can get involved to different degrees into renewable energies. They can invest or co-invest into wind or solar power plants. There are several providers who offer leasing contracts for solar power plants. Finally, mines can buy electricity through PPAs from renewable plants.
The plant database contains power plants with the following technologies:
There are different applications:
At this stage neither biomass (or biogas) nor hydro power plants are included. In addition, cases in which a mining company invests into renewable energy plants and does not consume the energy are not included either.
