There was an error in the database used by our “Electricity production, source: ARE” chart (“Electrical System” tab). It concerns the electricity generation from natural gas, which turned out to be underestimated by 30-60% relative to the correct value. Users downloading data in CSV format for the period from the beginning of 2023 onwards have received files with incorrect values.

The energy.instrat.pl team has corrected the database and fixed the described error. We apologise for the issue and thank you for your understanding.
