| - | In recent years, German experts on energy statistics have expended considerable efforts on the task of minimizing the differences between the provisional and final Energy Balances. In 2020, the Federal Statistical Office obtained the EU grant “improvement of timeliness of energy statistics” from EUROSTAT. In the framework of a dedicated project, this funding is expected to enable the Federal Statistical Office to provide data for year x-1, to the AGEB, as early as August of the relevant year. The pertinent project was launched in 2020, and it includes the statistical offices of the Länder, which are responsible for the concrete surveys involved. Key surveys for the preparation of the Energy Balance and the emissions inventories have been given temporal priority. As a result, the Federal Statistical Office, working on the basis of the data collected by the reference date, and using imputation procedures, was able – in July 2020 – to extrapolate a complete data set for the year 2019. In July 2021, the so-developed methods were used in routine operations for the first time. In October 2021, quality assurance for the methods was carried out by comparing the extrapolated results with the final 2020 survey data. In the 2022 survey year, the resulting methodological improvements made it possible to prepare a considerably improved provisional Energy Balance, now based, for the first time, on extrapolations – the 2021 provisional Energy Balance. The participating institutions coordinated their scheduling for the relevent data flow so carefully that a number of process steps were carried out in the shortest possible time, and the relevant data were made available for inventory preparation in reporting year 2023. | + | In recent years, German experts on energy statistics have expended considerable efforts on the task of minimizing the differences between the provisional and final Energy Balances.
