[Simona Vazio] «Electricity data is a fundamental asset for the national economy. Terna, the national transmission grid operator, collects and processes this data as part of the daily operations of Italy’s electricity system. This same data forms the basis of statistical processing, scenarios and analyses, as well as processes, maintenance and strategic infrastructure development, which are all essential in the context of the energy transition».

[Simone D'Ascenzo] «The electricity system is a structured and complex mix of assets, processes and data. Today I want to focus on data: managing measurements has significant implications for managing Italy’s electricity system and their disclosure serves as a thermometer of our country’s economic performance».
[Simona Vazio] «Throughout the year, Terna constantly measures all systems connected to the high-voltage and extra-high-voltage grid and estimates the portion of what we call “distributed generation”, i.e. small plants connected via medium and low voltage, and also estimates the portion of energy produced and injected into the grid. Around six months later, my Statistics Office, which is part of the National Statistical System, publishes the definitive data of Italy’s electricity sector following a census-type survey with 5,200 operators, distinguished between producers and distributors. Simone, how do you build the national electricity balance sheet, published monthly on Terna.it?».
[Simone D'Ascenzo] «The Balance Sheet is all the information taken from the field (measurements, remote measurements and programmes), which is aggregated and processed according to logics and algorithms that make it possible to guarantee the total measurability of the system. This is how Terna publishes the Requirements each month, i.e. the demand for electricity that the system must satisfy, plus the production items for each kind of source. Simona, how do you use the Balance Sheet data that we give you each month?».
[Simona Vazio] «Hmm… As you know, this data is fundamental for economic analyses, which my team processes each month and provides to various institutional stakeholders. We’ll cover this topic in an upcoming episode, but I can reveal that the requirements data is ‘purged’ of the calendar, temperature and seasonality effect to make it comparable with the same month in the previous year. Our data must be considered as anticipatory data needed to interpret the dynamics of the national economy».
[Simone D'Ascenzo] «And it also provides an overview of strategy documents and fundamental analyses, such as those dedicated to provisional energy forecast scenarios and processed with the aim of evaluating the benefits of transmission grid development projects, as well as contributing to the achievement of national policy objectives».
«We’ve been Simona Vazio and Simone D’Ascenzo and you’ve been listening to the first episode of Sala Dati, the podcast about electricity consumption in Italy explained by Terna professionals».
