Real-time demand and generation

Red Eléctrica provides graphs that show, in real-time, the electricity demand on the Spanish peninsula. The graphs 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.

 

Along with the graphs, information is shown regarding the different production technologies or generation mix necessary to meet the demand, including the energy to be exported and that corresponding to pumped storage consumption.

Additionally, it also shows the equivalent CO2 emissions associated with the overall set of power generating facilities nationwide and which currently represent about 17% of the total GHG emissions in Spain.

The information provided includes the total CO2 emissions (expressed in t CO2 eq / MWh) generated by each of the Spanish electricity systems as well as detailed data regarding CO2 emissions per hour and technology.

In order to calculate the emission factors of each technology and electricity system, we use different sources depending on the best availability of information.

  • The actual demand (yellow curve) shows the instantaneous value of electricity demand.

  • The demand forecast (green curve) is drawn up by Red Eléctrica based on historical electricity consumption data from similar periods, adjusting it by using a series of factors which influence consumption, such as working and seasonal patterns, and economic activity.

  • The hourly operating schedule (stepped red line) shows the scheduled production of the generating units which have been allocated the responsibility of supplying the electricity required to meet the forecasted demand. The schedule and allocation is established through the matching of the day-ahead and intraday markets, as well as the deviation management and tertiary control markets. Red Eléctrica, based on the evolution of the electricity demand, manages the latter two markets.

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.

 

Balearic Islands’ daily balancing

Red Eléctrica provides graphs that show the electric energy demand curve in real time for each of the four islands that make up the Balearic islands' electricity system, two of which: Mallorca and Menorca, Ibiza and Formentera are interconnected by a submarine link. Data regarding programmed generation, actual and forecasted demand is updated every ten minutes, and the graph also shows the values of the maximum and minimum daily demand.

Together with the curves, information is shown regarding the various generation technologies that are available to meet this demand and the equivalent CO2 emissions associated with the complete set of thermal generation facilities.

Canary electricity demand in real-time

Red Eléctrica provides graphs that show the electric energy demand curve in real time for each of the seven islands that make up the Canary islands' electricity system, two of which - Lanzarote and Fuerteventura - are interconnected by a submarine link. Data regarding programmed generation, actual and forecasted demand is updated every ten minutes, and the graph also shows the values of the maximum and minimum daily demand.

Together with the curves, information is shown regarding the various generation technologies that are available to meet this demand and the equivalent CO2 emissions associated with the complete set of thermal generation facilities.
