Name: GoiEner smart meters data Summary: 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: raw.tzst, contains raw time series of all GoiEner clients (any date, any length, may have missing samples). imp-pre.tzst, contains processed time series (imputation of missing samples), longer than one year, collected before March 1, 2020. imp-in.tzst, contains processed time series (imputation of missing samples), longer than one year, collected between March 1, 2020 and May 30, 2021. imp-post.tzst, contains processed time series (imputation of missing samples), longer than one year, collected after May 30, 2020. metadata.csv, contains relevant information for each time series.

Objective of collection: This dataset was originally used to establish a methodology for clustering households according to their electricity consumption. Description: The meaning of each column is described next for each file. raw.tzst: (no column names provided) timestamp; electricity consumption in kWh. imp-pre.tzst, imp-in.tzst, imp-post.tzst: “timestamp”: timestamp; “kWh”: electricity consumption in kWh; “imputed”: binary value indicating whether the row has been obtained by imputation. metadata.csv: “user”: 64-character identifying a user; “start_date”: initial timestamp of the time series; “end_date”: final timestamp of the time series; “length_days”: number of days elapsed between the initial and the final timestamps; “length_years”: number of years elapsed between the initial and the final timestamps; “potential_samples”: number of samples that should be between the initial and the final timestamps of the time series if there were no missing values; “actual_samples”: number of actual samples of the time series; “missing_samples_abs”: number of potential samples minus actual samples; “missing_samples_pct”: potential samples minus actual samples as a percentage; “contract_start_date”: contract start date; “contract_end_date”: contract end date; “contracted_tariff”: type of tariff contracted (2.X: households and SMEs, 3.X: SMEs with high consumption, 6.X: industries, large commercial areas, and farms); “self_consumption_type”: the type of self-consumption to which the users are subscribed; “p1”, “p2”, “p3”, “p4”, “p5”, “p6”: contracted power (in kW) for each of the six time slots; “province”: province where the user is located; “municipality”: municipality where the user is located (municipalities below 50.000 inhabitants have been removed); “zip_code”: post code (post codes of municipalities below 50.000 inhabitants have been removed); “cnae”: CNAE (Clasificación Nacional de Actividades Económicas) code for economic activity classification. 5 star: ⭐⭐⭐ Preprocessing steps: Data cleaning (imputation of missing values using the Last Observation Carried Forward algorithm using weekly seasons); data integration (combination of multiple SIMEL files, i.e. the data sources); data transformation (anonymization, unit conversion, metadata generation). Reuse: This dataset is related to datasets: "A database of features extracted from different electricity load profiles datasets" (DOI 10.5281/zenodo.7382818), where time series feature extraction has been performed. "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. Update policy: There might be a single update in mid-2023. Ethics and legal aspects: 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. Technical aspects: raw.tzst contains a 15.1 GB folder with 25,559 CSV files; imp-pre.tzst contains a 6.28 GB folder with 12,149 CSV files; imp-in.tzst contains a 4.36 GB folder with 15.562 CSV files; and imp-post.tzst contains a 4.01 GB folder with 17.519 CSV files. Other: None.
