The mining industry faces a dual challenge: ensuring a reliable power supply while minimising its environmental impact. As the world transitions to cleaner energy sources, solar power emerges as a compelling solution. However, to fully harness its potential, the industry must develop a skilled workforce capable of building and maintaining solar power plants.

Mining is a power-hungry industry
Mining operations are renowned for their energy-intensive nature, demanding consistent power for a myriad of processes. From powering heavy machinery like excavators and crushers to operating ventilation systems and pumps in underground mines, electricity is the lifeblood of these operations. Historically, the industry has relied heavily on the national grid, often facing challenges related to power outages, load shedding, and fluctuating electricity costs.

While recent economic headwinds have temporarily reduced industrial activity, including mining, easing the pressure on the national grid, this is a short-term reprieve. As the global economy rebounds and the demand for minerals increases, so too will the mining sector's energy consumption, which is roughly 30% of Eskom’s annual power supply, according to Minerals Council South Africa. 

The power of solar for mining
To ensure uninterrupted operations and mitigate risks associated with grid instability, mining companies are increasingly turning to on-site power generation. Solar energy is a compelling solution to power challenges, due to its sustainability and growing cost-competitiveness. By installing large-scale solar panel farms on mine sites, companies can generate clean electricity directly where it is needed, reducing their dependence on the grid. This not only helps to stabilise energy costs but also provides a hedge against future tariff increases. Moreover, solar power generation aligns with the global shift towards renewable energy sources, enabling mining companies to improve their environmental performance and reduce their carbon footprint.

Beyond cost savings and environmental benefits, solar power can enhance operational efficiency. For remote mine sites with limited grid access, solar energy can provide a reliable and cost-effective power source. Additionally, by generating electricity on-site, mining companies can reduce transmission losses, further optimising energy utilisation.

Building a skilled solar workforce
The successful integration of solar power into mining operations hinges on a skilled workforce capable of handling every stage of the solar energy lifecycle, which necessitates a significant investment in human capital development. A critical component of building a skilled solar workforce is the establishment of formal qualifications. Here, the introduction of a general technician qualification for solar installation is a vital step in ensuring that individuals possess the necessary knowledge and skills to work safely and efficiently. 

By standardising training and certification, the industry can enhance quality, safety, and professionalism. A qualified workforce not only benefits the employees themselves but also instils confidence in clients and stakeholders. It demonstrates a commitment to quality and adherence to industry best practices.

Targeted upskilling and reskilling
To address the specific needs of the mining sector, targeted upskilling and reskilling programs are essential. By leveraging existing mine technician skills and combining them with solar technology training, the industry can create a highly competent workforce. 

Additionally, the integration of solar technician training into social labour plans by mining houses provides an opportunity to empower local communities. By training community members as solar technicians, mining companies can contribute to local economic development and create sustainable employment opportunities.

As an example, the Exxaro project, which involves the development of a 60-hectare solar plant, offers a model for community engagement. By training local residents as solar technicians, the project not only supports the mine's renewable energy goals but also uplifts the community. Targeted training programmes in partnership with the Energy & Water SETA, provide the necessary skills and qualifications for individuals to excel in the solar industry. By creating a clear career path, these programmes foster a skilled workforce capable of designing, installing, and maintaining solar power plants.

A brighter future through solar power
As South Africa works towards a low-carbon economy, the mining industry has an opportunity to lead the way in renewable energy adoption. By investing in upskilling and reskilling programmes, the sector can secure its energy needs, create jobs, and contribute to a more sustainable future. The transition to solar power presents both challenges and opportunities, but with the right skills and support, the mining industry can successfully harness the power of the sun.
