Research series Consumer price index electricity and gas
Erratum:
With the April 2026 update, two values of the research series of 'Year-on-year change CPI' in table 1 have been corrected. The original values were incorrectly rounded. It concerns the figures for March 2022 (changed from 4.3% to 4.2%) and April 2023 (changed from 10.3% to 10.2%). In addition, a value of the research series of 'Year-on-year change electricity’ in table 2 has been corrected. It concerns the figure for April 2022 (changed from 0.5% to 0.4%). This value was also incorrectly rounded in the original version.The new method is implemented as of reporting month June 2023. The article presents the so called research series with reporting months January 2020 – May 2023 of the CPI, for both the index and inflation (% year-on-year change). These figures are available in table 1. Tables 2 and 3 present the index and year-on-year change in percentages for the research series of electricity and gas separately. In addition to the regular series, the derived series are presented. They present the price index without the effect of changes in consumption related taxes and subsidies. For all tables present in this file, the published figures are presented next to the research series.
In April 2026, this publication has been supplemented with tables 4 and 5. These tables also contain the research series for all higher aggregates and special aggregates that include electricity and gas. Tables 4 and 5 are compiled based on the exact same source information as the figures from 2023. It is merely an extended presentation. Table 4 contains the regular indices and table 5 contains the derived indices.
