This dataset presents the amount of electricity injected into the grid by Self-Consumption Production Units (UPACs), organized by district and municipality.The data refers to registered UPACs, regardless of whether they have a surplus energy sale agreement.Energy injected into the grid corresponds to the energy produced minus the energy self-consumed at the installation.It provides a detailed view of the contribution of these units to the electricity system, enabling the assessment of the role of self-consumption in the energy transition and in increasing distributed renewable generation.Through this data, it is possible to identify production patterns, monitor the penetration of UPACs across different regions, and support the planning of electricity networks and energy communities.Use cases:Assess the energy injected into the grid by UPACs across different geographic areas.Support the analysis of local energy balances for energy communities and collective self-consumption projects.Study the impact of self-consumption on the electricity grid and the integration of renewable energy sources.Assist in planning network expansion and reinforcement to improve the integration of distributed generation.Update frequency: MonthlyIncluded variables:Date — Reference date of the information.District — Name of the district where the generation installation is located.Municipality — Name of the municipality corresponding to the generation installation.Voltage Level — Electrical voltage level at the installation connection point (e.g., Low Voltage, Medium Voltage), indicating the connection tier of the UPAC to the grid.Installed Capacity (kW) — Sum of the installed electrical capacities of the generation units (in kilowatts), reflecting the maximum generation capacity of the UPACs.Number of Installations — Number of Self-Consumption Production Units (UPACs).Injected Energy (kWh) — Total amount of electricity injected into the public grid by UPACs (in kilowatt-hours).1. The information made available by E-REDES constitutes an approximation of the values extracted from its systems and reflects the moment at which the information is collected. Given that connection points, the electricity distribution network, and consumption and generation values are inherently dynamic, the information provided may be subject to subsequent changes and updates. Possible omissions and/or occasional location inaccuracies may also exist.2. Therefore, E-REDES shall not be liable to third parties, including partners, service providers, contractors, users, and customers, for any damages that may arise directly or indirectly from the use of this information, particularly when carrying out interventions, calculations, and/or estimates without first confirming the accuracy and currency of the data.
