This Dataset represents the best consumption information up to date, presenting a forecast until the end of the year.The Dataset is composed of the following elements:Energy consumption of installations with MAT voltage level (very high voltage);Energy consumption of installations with AT voltage level (high voltage);Energy consumption of installations with MT (medium voltage) voltage level;Energy consumption of installations with BT voltage level (low voltage);Sum of energy consumption of all voltage levels (Total).The data is obtained through the best information on existing consumption until the data, making a forecast until the end of the year based on historical values. At the end of each 15-minute period, the total amount corresponds to the energy during that interval.The update frequency is monthly.Use case: This data allows you to monitor the best information on national energy consumption, quarter-hourly by voltage level during the year in question.1. The information made available by E-REDES constitutes an approximation to the values taken from the system and is based on the moment in which it is collected. Given that the connection points, the electricity distribution network, and the consumption and production values themselves are naturally very dynamic, it is safeguarded that the information made available may be subject to subsequent changes and updates, with the exception of any omissions and/or occasional inaccuracies of location that the information may contain.2. In this way, E-REDES is not liable to third parties, namely, partners, service providers, contractors, users and customers, for damages that may arise as a result, direct or indirect, of the use of this Information, in particular when carrying out interventions, calculations and/or estimates, without confirming the accuracy and updating of the data, whereby it is duly noted that the consultation of this information does not affect the duty to promote a direct consultation with E-REDES in order to obtain updated information.The data provided by the E-REDES Open Data Portal is covered by open licenses (CC BY 4.0).
