For processed data files more suitable for use, please refer to the GoiEner Smart Meters Data dataset: DOI 10.5281/zenodo.7362094 The GoiEner Raw Files dataset contains a complete set of raw data from the customer database of the Spanish renewable energy cooperative GoiEner, obtained from smart meters. Founded in the Basque Country in 2012, GoiEner has made available this extensive dataset, which includes the raw electricity consumption data (and self-generation) for all its customers. The supply points provided comprise a diverse range of customers, such as households, offices, small and medium-sized enterprises (SMEs), industrial buildings, and public facilities. This dataset spans the entire period from the first records using smart meters in late 2014 until June 2022. It consists of 71,048 files containing information on consumption, generation, contracted power, pricing, and other related data for each supply point in the grid. These files serve as the primary source for managing electricity supply contracts between distributors and retailers, as well as for user billing. The formats and specifications of the files adhere to the guidelines set by the Spanish electricity market regulator, the National Commission of Markets and Competition (CNMC), which establishes the Electricity Metering Information System (SIMEL).
