Electric Power System of the Balearic Islands
Description of the electric power supply of the Balearic Islands. Menorca. On Menorca just a single power plant exists at Mahon ( Maó ) at . It is oil fired and has a net generation capacity of 245 MW. From it 2 132 kV-lines run to Dragonera substation. 132 kV/15 kV-Substations. Beside the connection between Mahon ( Maó) power station and Dragonera substation, there is a 132 kV-line interconnecting the following substations. Power cable to Mallorca. A 132 kV-line links Ciutadella substation on Menorca with Es Bessons substation on Mallorca. It runs from  Ciutadella substation overhead to Celan Bosch cable terminal at where the submarine cable to Mallorca starts. It ends at Cala Mesquida cable terminal at Cala Mesquida , where the overhead line to Es Bessons substation starts. Ibiza/Formentera. On Ibiza and Formentera, there are two thermal power stations, one on Ibiza, the other on Formentera. 69 kV/15 kV substation. The substations on Ibiza are interconnected together with Elvissa Power Station over a 69 kV-ring running from Elvissa Power Station via Torrent, Santa Eularia, Sant Antoni and Sant Jordi. Beside this, there is a connection between Torrent and San Antonio. Since  2007 a 69 kV-cable with a capacity of 50 MW connects the powergrid of Formentera with that of Ibiza. The terminals of this cable are Torrent and Formentera Power Station. From Torrent a 132 kV three phase AC link to Santa Ponsa, Mallorca is under construction (capacity 2 x 100 MV). Mallorca. Power Stations. There are four thermal power plants on Mallorca. The first two feed in the 220 kV-grid HVDC-connection to the mainland. An HVDC cable (±250 kV) with the name Cometa has been commissioned in August 2012. The converter substation is at Santa Ponsa . It  will also contain a 220 kV/132 kV-substation, from which a 132 kV submarine cable for three-phase AC will run to Torrent on Ibiza. 220 kV/69 kV-Substations. The backbone of power supply of Mallorca is the 220 kV grid. The following stations are in service 2 lines interconnect Valldurgent with Son Reus, Llubi with Murterar PowerStation and Llubi with Es Bessons substation. A single ring-line interconnects Llubi, Son Reus and Son Orlandis substation. New 220 kV-substations are planned/under construction at Santa Ponsa, Rafal, Latzer and Lucmajor. A three-phase 132 kV AC cable between Es  Bessons and Ciutadella on Menorca is under construction. 69 kV/15 kV-Substations. Distribution of electric power is done by 69 kV and 15 kV grids. The following 69 kV stations are in service.
