One of the primary infrastructure-related obstacles in the development of electromobility is currently the deficit of fast charging points, whose range would cover the incomplete road network in Poland and whole Europe. The rapid development of transport based on electricity will pose an enormous challenge for electricity producers and distributors but will also give them an even 20% increase in the market of consumers. Bearing the above aspects in mind, KGHM Polska Miedź S.A. commenced decisive actions towards broadly understood electromobility in 2018 through the gradual and consistent replacement of own transport fleet with zero-emissions electric vehicles, but above all through the development of ultra-fast charging stations available to the public in the LGOM area. The first station was created at the KGHM Head Office already in December 2018 and it was followed in 2019 by successive ones at the Głogów Copper Smelter, Legnica Copper Smelter and Lubin Mine Divisions. Each “charger” has three types of connectors, which ensures full compatibility with the vehicles that are available on the market. The stations are included in the IT system of Tauron Dystrybucja Serwis. The support for the electromobility development program provides for free charging for the users, which is beneficial to the environment and climate.
In addition, as part of actions for protection of the environment and climate as well as health and working comfort of the employees, KGHM Polska Miedź S.A. performs works aimed to reduce dust and gas emissions from mining machine engines, in particular of nitrogen oxides and solid particles. The objective is to reduce employees’ exposure to nitrogen oxide at workplaces and to achieve concentrations below 2.5 mg/m³ and to reduce the exposure to carcinogens to the level of 0.05 mg/m³ in terms of elemental carbon.
At present, KGHM pursues an investment process related to the purchase of machinery, as part of which engines according to the Stage IV and V are gradually introduced, which enables several-fold reduction of emissions. Currently (in 2020), about 10% out of 1,261 machines used at KGHM are low-emission. All new machines are purchased complete with engines complying with strictest flue gas purity standards. Replacement of all the machinery will be possible at the end of 2026.
KGHM Polska Miedź S.A. also cooperates with external manufacturers on testing the functionality and effectiveness of mining machines with a battery-powered electric drive. The effects of these measures include tests of a battery anchoring car at the Lubin Mine. A drilling car and a self-propelled electric transport vehicle will be delivered for testing in Q2 2021. Moreover, determinations concerning the commencement of testing of an electric charger at the Rudna Mine are at an advanced stage.
