ABSTRACT
The volatility of raw material prices and the rising prices of CO2 emission allowances when using fossil fuels to produce electricity and heat are still relevant problems for owners of generating units. The decision-making tools are used in the fuel purchase process. However, these tools should also consider environmental issues.
The article’s main objective is a quantitative analysis of the potential for reducing costs associated with supplying and using hard coal in public power plants as a result of considering the costs of environmental protection and CO2 emission allowances in the process of planning this fuel supply. A mathematical model was developed to optimize the supply of hard coal for the power industry. The tool and elaborated research scenarios made it possible to calculate and analyze the impact of considering the costs of emissions of harmful substances into the environment and CO2 emission allowances on the planning of coal supplies and the reduction of costs related to acquiring and using coal by public power plants. The calculation results were presented on the example of the Polish power sector.
The model’s results confirm that the appropriate selection of coals, taking into account the quality parameters determining the amount of emissions of harmful substances, reduces the amount of these emissions and the total costs of acquiring and using coal in electricity production. However, depending on the considered scenario, the scale of this impact varies. The results of the optimization of coal supplies to power plants and their proper interpretation may constitute an important contribution to making management decisions in energy companies.

Pozyskiwanie węgla kamiennego z uwzględnieniem wybranych regulacji środowiskowych – studium przypadku polskiego sektora energetycznego
węgiel kamienny, regulacje środowiskowe, modelowanie matematyczne, dostawy węgla, sektor energetyczny
Problem zmienności cen surowców, wzrastających cen uprawnień do emisji CO2 oraz zaostrzanych limitów emisji przy wykorzystywaniu paliw kopalnych do produkcji energii elektrycznej i ciepła jest wciąż aktualny dla właścicieli jednostek wytwórczych. Budowane narzędzia wspomagające proces podejmowania decyzji przy doborze surowców do procesu spalania powinny jednak uwzględniać również kwestie środowiskowe.
Głównym celem artykułu jest ilościowa analiza potencjału redukcji kosztów związanych z pozyskaniem i wykorzystaniem węgla kamiennego w elektrowniach zawodowych, w rezultacie uwzględnienia w procesie planowania dostaw tego paliwa, kosztów ochrony środowiska oraz uprawnień do emisji CO2. Opracowano model matematyczny do optymalizacji pozyskiwania węgla kamiennego przez energetykę zawodową. Zbudowane narzędzie oraz opracowane scenariusze badawcze umożliwiły przeprowadzenie obliczeń i wykonanie analizy wpływu uwzględnienia kosztów ochrony środowiska oraz uprawnień do emisji CO2 w procesie planowania dostaw węgla, na redukcję kosztów związanych z pozyskaniem i zużyciem węgla w elektrowniach zawodowych.
Wyniki modelu potwierdzają, że odpowiedni dobór węgli wpływa na redukcję całkowitych kosztów pozyskania i wykorzystania węgla w procesie produkcji energii elektrycznej. Wyniki optymalizacji dostaw węgla do jednostek wytwórczych i ich właściwa interpretacja mogą stanowić istotny wkład w podejmowaniu decyzji zarządczych w przedsiębiorstwach energetycznych.
