During the project for KGHM, BESTECH evaluated prime mover and utility battery electric vehicle (BEV) equipment and conducted a cost-benefit analysis.

They compared the development, capital, operating, maintenance, and handling costs of BEVs to diesel-powered equipment, considering energy reductions for the mine's lifespan. Additionally, they studied battery ownership versus Battery-as-a-Service (BaaS) case studies, summarized the total cost of ownership, and compared the performance and carbon emissions of BEVs to diesel equivalents.

BESTECH reviewed the KGHM electrical infrastructure to ensure its compatibility with BEVs. We conducted a comprehensive risk analysis, in consultation with the owner’s representatives, to assess potential HSE implications associated with operating and maintaining BEVs, such as fire risks related to batteries and electric shock hazards. BESTECH also examined the training requirement of people with expertise and the maintenance in BEVs, and determined the ideal locations for charging stations.

In order to determine the impact of BEV implementation, BESTECH assessed the potential savings in ventilation, cooling, and heating costs. We also conducted a risk assessment and summarized the overall reduction in greenhouse gas emissions. BESTECH also collaborated with KGHM to apply for funding through the IESO’s Industrial Energy Efficiency Program “Save On Energy.” Additionally, BESTECH conducted a Detailed Engineered Study (DES) analysis to determine eligibility for grants and incentives, including programs available through Ontario’s critical mineral strategy.
