title: GoiEner smart meters data

description: <strong>Name</strong>: GoiEner smart meters data <strong>Summary</strong>: The dataset contains hourly time series of electricity consumption (kWh) provided by the Spanish electricity retailer GoiEner. The time series are arranged in four compressed files: <strong>raw.tzst</strong>, contains raw time series of all GoiEner clients (any date, any length, may have missing samples). <strong>imp-pre.tzst</strong>, contains processed time series (imputation of missing samples), longer than one year, collected before March 1, 2020. <strong>imp-in.tzst</strong>, contains processed time series (imputation of missing samples), longer than one year, collected between March 1, 2020 and May 30, 2021. <strong>imp-post.tzst</strong>, contains processed time series (imputation of missing samples), longer than one year, collected after May 30, 2020. <strong>metadata.csv</strong>, contains relevant information for each time series. <strong>License</strong>: CC-BY-SA <strong>Acknowledge</strong>: These data have been collected in the framework of the WHY project.

"Measuring the flexibility achieved by a change of tariff" (DOI 10.5281/zenodo.7382924), where the metadata has been extended to include the results of a socio-economic characterization and the answers to a survey about barriers to adapt to a change of tariff. <strong>Update policy:</strong> There might be a single update in mid-2023. <strong>Ethics and legal aspects:</strong> The data provided by GoiEner contained values of the CUPS (Meter Point Administration Number), which are personal data. A pre-processing step has been carried out to replace the CUPS by random 64-character hashes. <strong>Technical aspects:</strong> <strong>raw.tzst</strong> contains a 15.1 GB folder with 25,559 CSV files; <strong>imp-pre.tzst </strong>contains a 6.28 GB folder with 12,149 CSV files; <strong>imp-in.tzst</strong> contains a 4.36 GB folder with 15.562 CSV files; and <strong>imp-post.tzst</strong> contains a 4.01 GB folder with 17.519 CSV files. <strong>Other:</strong> None.
