Abstract

The structure of electricity production in Poland has not changed dramatically recently. Approximately 93% of electricity is currently produced from coal and lignite. Environmental charges have a significantly impact on costs of production. This paper analyses the impact of environmental charges influenced by coal quality on the production cost of power generation. A simulation of the impact of coal quality (Q, A, S) on the environmental charges was carried out. The study was extended by the analysis based on improved relationship between coal quality and emission charges. The calculations included also charges related to the NOx, CO and CO2. The results are presented per 1 ton of coal burned and per 1 MWh of electricity produced.

Abstract

According to various sources, between approximately 8.5 and even 10 million tons of Russian coal entered Polish market in 2022, which was mainly used for heating purposes by heating companies and private households (especially in the northern regions of the country). A ban on the continuation of these imports requires the identification of other sources of fuel – these could be either imports from other countries or an increase in mining volumes by domestic mines. However, both of these alternatives require a certain amount of time to be realized. Finding new foreign suppliers entails new contracts, which can be all the more difficult as many other countries, like Poland, no longer want to buy Russian coal. And then there is the issue of negotiating appropriate prices.
A possible decision to increase domestic mining is linked to other problems. This requires, first and foremost, that new portions of the deposits that could be mined be made available and cut in advance, which often entails several years of underground roadworks and significant financial outlays for their implementation and for the appropriate technical equipment of the newly prepared mining faces. With appropriate financial support from the state, this may be possible but not in every mine as there are a number of other considerations that determine the volume of extraction that can be achieved, particularly if there is a desire to increase it.
The aim of this publication is to present, analyse and identify factors that directly influence the volume of hard coal production, taking into account the dynamically changing market environment.
