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 39.89694°N, 4.25861°W. 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 39.93194°N, 3.83361°W where the submarine cable to Mallorca starts. It ends at Cala Mesquida cable terminal at Cala Mesquida 39.73861°N, 3.42722°W, 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).

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 39.53389°N, 2.50583°W. 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.
