In facilities distributed throughout the country and using state-of- the-art technology, Red Eléctrica captures the data required to operate the electricity system under secure conditions. With these values, it manages the availability of the power stations, any possible restrictions of the transmission grid, the international exchanges and, in addition, it forecasts the demand.

On these graphs, Red Eléctrica shows, in real time, the demand for electrical energy on the Spanish peninsula. These include data, updated every ten minutes, of the actual demand, the forecasted demand and the scheduled demand, as well as the maximum and minimum values of the daily demand.

Together with the graphs, information is shown regarding the different production or generation technologies necessary to meet the demand in real time, including the energy to be exported and that corresponding to consumption of pumps. In addition, it also shows the CO₂ emissions associated with power generation assets on the Spanish peninsula, which represents approximately 28% of total emissions.

The real demand (yellow curve) represents the instantaneous power demand value.
The demand forecast (green curve) is drawn up by Red Eléctrica based on historic data regarding electricity consumption, adjusting it by using a series of factors which influence the value, such as working and seasonal patterns, and economic activity.
The hourly operating schedule (staggered red curve) shows the planned output of the generating units responsible for supplying energy to meet the share of the market power demand allocated to each unit, during the daily and intraday markets matching, as well as in the markets responsible for deviations and tertiary control management. Red Eléctrica based on the evolution of the electricity demand manages the two last mentioned markets.
Along with this generation structure, the total CO₂ emissions produced by power generation assets on the Spanish peninsula are presented and detailed by energy sources. Such emissions are calculated by associating to each technology the emission factor established in the Spanish Renewable Energy Plan 2005-2010, in line with the Decision of the European Commission 2007/589/CE.

The interval-based electricity demand graph also enables the peninsular demand to be analysed during different periods of time and helps check uniform behaviour in the daily demand.
