Fluctuations of Natural Gas Prices for Households in the 2017–2022 Period—Polish Case Study
Abstract
The considerable share of natural gas in the aggregated gross available energy clearly indicates the resource’s importance for the energy security of EU states. Natural gas shortages caused by energy crises result in the resource’s price increases in foreign markets. The condition of the global energy system translates directly to the prices of natural gas for households. The main research objectives were the analysis of prices of household natural gas in the EU, and identification of key factors affecting the prices of household natural gas in Poland and their effect on the prices established in domestic tariffs. The secondary data analysis method (desk research) was used in the research. The 2017–2022 data were acquired from Eurostat, the Polish distributor’s (PGNiG SA) tariffs, the Energy Regulatory Office and exchange information. The paper fills a research gap in the disparity of prices of natural gas supplied to final individual recipients in the EU. It was established that the sudden increases in natural gas purchase prices on energy resource exchanges translated into a similarly dynamic increase in the household gas fuel prices. The price data concerning Poland were compared to analogous data from other EU member states. It was established that in the period between the first half of 2021 and the first half of 2022, gas prices in the EU increased by over 34% on average (maximum of 150%). It was concluded that the household natural gas prices in Poland, established in the officially approved distribution tariffs of PGNiG SA, are substantially affected by two factors: energy resource purchase prices on the Polish Power Exchange (TGE), and purchase prices on foreign markets. The main reason for price increases was the unforeseen substantial changes in the conditions of conducting business activity by PGNiG SA in terms of gas fuel trading, resulting from the increase in high-methane natural gas purchase price at the TGE. On the other hand, the increases in purchase price of natural gas imported from EU or EFTA member states by 2021 have moderately translated into increases in prices established in officially approved tariffs. A similar effect of household natural gas price increase has also occurred in other EU member states but was not uniform. The effect depended on the volume of gas production and consumption in the given country, and on the diversity of gas sources that determined the resource’s purchase price.
