3.1. Data description

In Italy there are three ONAs that deal with energy statistics and are responsible for Eurostat data transmission.

  • The Ministry of Ecological Transition is responsible for fossil energy: Oil, natural gas , coal.
  • GSE – Gestore dei Servizi Energetici is responsible for renewable energy (REN AQ), for renewable target monitoring (SHARES tools) and for some specific topics as Household energy consumption (Household AQ) and District Heating and District Cooling (DH-DC Questionnaire)
  • Terna, National TSO, is responsible for data of the Italian electricity sector (ELE AQ) and for data on CHP plants (CHP Questionnaire).

The statistics produced are consistent with each other.

National metadata reflects data collection included in National Statistical Program and are divided by ONAs, when possible. The National Statistical Program (PSN) is the regulatory act, based on art. 13 of the legislative decree n. 322 of 1989, which sets the statistical data collection of public interest among the National Statistical System and the related information purposes.

Name of the national data collection Most important quality problem of this data collection Measures taken in the last 5 years to improve quality of the data collection
Data collection on renewable energy in heating sector - direct use and of derived heat (GSE-00001) Data are available on number and territorial distribution of plants, but sometimes not on their use (hours/year, days/year)

Quality and quantity of data available from local administrations are not homogeneous		 We are in a continuous process to improve the quality, by improving questionnaires, double checks, internal coherence checks etc.
Numerous calculation files have been redesigned and enriched with information, in order to allow anyone to continue the activity even in the absence of those who had done the work in previous years, significantly reducing the probability of error.
Some indicators for monitoring the effectiveness of the processes and the quality of the acquired data have been introduced.
The burden on respondents was reduced through specific agreements in case of double surveys.
In general, every year data acquisition process improves: on one side, the questionnaire is simplified by removing useless questions; on the other side, new questions are added, if needed.

  • Gestore dei Servizi Energetici: Each time series released by the Statistical Office is fully consistent both in terms of variables and units of measurement
  • Terna: For all variables, except consumption, there have been some changes but not enough to warrant the designation of a break in series; most of the changes involved the addition of information. Instead, for consumption there have been sufficient changes to warrant the designation of a break in series. In 2019 the classification of economic activities (from ATECUE95 to ATECUE 2007) changed and was updated, creating a break in series.
15.2.1. Length of comparable time series
  • Ministry of Ecological Transition : Some data are available from 2003 (Bollettino petrolifero), other from 1998 (Bilancio energetico nazionale).
  • Gestore dei Servizi Energetici: Some data are available from 1990, other from 2004. Time series is fully consistent, there have not been any relevant breaks.
  • Terna: Regarding the most important variables: for production there are ((2020-1990)+1)*12 comparable time points (one per month since 1990) and for capacity there are (2020-1990)+1 comparable time points (one per year since 1990). For consumption, when comparing consumption by economic activity (see 15.2) there are (2019-1990)+1 comparable time points before 2019 and two comparable time points after 2019.

18.3. Data collection
  • Ministry of Ecological Transition: Respondents provide data through an online web application I-Sisen developed specifically for all products covered by this data survey.  A several automatic controls are combined with manual checks performed by internal operators and ensure the data reliability
  • Gestore dei Servizi Energetici: Depending from different variables. We use data from internal and external administrative archive, market data, direct surveys, online web application Biocar. All data collection includes constant checks on different topics: coverage of the reference universes, adequacy of classifications and definitions, completeness of the acquired data, internal consistency of the data, consistency with other sources also with the help of experts. Appropriate procedures are applied to develop and test the questionnaire. To define the starting lists, to contact and motivate the respondents (limiting their effort as much as possible), to guarantee the correct management of the acquired data; appropriate procedures are also adopted to limit criticalities associated with the possible non-coincidence of the definitions used as well as to process, verify and use the data.
  • Terna: Respondents provide data through an online web application Gstat developed specifically for the electricity data survey. The application is progressively and internally developed, updated and tested. It includes a set of controls to minimise recording errors, both “hard” and “soft”. Automatic controls are combined with manual checks performed by internal operators. Massive checks are made regularly to compare our data with other sources. The questionnaire is self-administered. Data acquired from external sources are in turn entered into the web application and checked like all other data.

Institution Comment
Ministry of Ecological Transition No comment
Terna The starting date of the coverage period is set at 1990 in this quality report because it represents the first year available in the Eurostat database. However, data are available from 1963 onwards in Terna’s statistics office website.
Terna In 2020 Terna’s Statistics office did not have an administrative source; however, at the end of 2021 a public institution (Acquirente Unico) was appointed by Legislative Decree as the source of data on electricity consumption for the Ministry of Ecological Transition. Therefore, in 2022 Acquirente Unico was added Terna’s administrative source in the National Statistical Programme (2020-2022). It has only recently become an administrative source for our ONA. Indeed, procedures and timing for data transmission are yet to be defined.
Terna The monthly electricity questionnaire and the mini questionnaires are not cited in this quality report since they are based on provisional data.
Terna The quantities reported in 18.1 refer to the number of respondents interviewed, i.e., electrical operators.
GSE The mini questionnaires are not included in this quality report since they are based on provisional data.
