Real-time electricity demand in the Balearic Islands

Red Eléctrica provides real-time graphics of the electricity demand curves occurring in the electricity system on the Balearic Islands. Together with the curves, also shown is the information regarding the production technologies or generating components required to meet the demand, including the electrical energy transported from the Spanish mainland.

With the coming into service of the Rómulo project and the double submarine link that joins Majorca and Ibiza, the Balearic Islands are interconnected, allowing the electricity system of the Balearic Islands to be operated as a single system that, in turn, is connected to the mainland by a HVDC submarine link from Mallorca. These interconnection links play a very significant role in increasing the safety and quality of electricity supply throughout the archipelago.

Click on the graph of the Balearic Island’s system to consult the overall demand of the islands as a whole, and on any island to consult the specific demand for the island selected.

The graphics incorporate and display data every ten minutes of the actual, scheduled and programmed demand, as well as the maximum and minimum values of the actual daily demand.

  • Actual demand (yellow curve) reflects the instantaneous value of the electricity demand. The development of the curve reflects the peculiarities of the seasonal and working patterns, as well as the activity and essential way of life of the islands.
  • Forecasted demand (green curve) is calculated by Red Eléctrica based on the consumption values in similar previous periods, correcting it by factoring in a number of factors influencing consumption such as working patterns, climate and economic activity.
  • Operational hourly schedule (red stepped line) is the programmed production for the generation facilities to which the electricity supply has been allocated through the economic dispatching of the electricity system of the Balearic Islands. Also included is the electrical energy to be transported from the Spanish mainland that has been allocated in the peninsular day-ahead and intraday market.

Additionally, Red Eléctrica represents the actual daily demand in real time (yellow curve) of each of the islands of the Balearic archipelago. All demand curve graphics also provide information on the different production technologies or generating components necessary to meet demand and also the total CO2 emissions produced by the complete set of generation facilities of the Balearic Islands and the breakdown by energy sources.

Emissions are calculated by associating to each technology the emission factor set out in the Spanish Renewable Energy Plan 2005-2010, in line with European Commission Decision 2007/589/EC.
