Description of the electric power supply of the Balearic Islands.
Contents
Menorca
On Menorca just a single power plant exist at Mahon ( Maó ) at 39°53′49″N 4°15′31″E. It has a generation capacity of 101.2 MW. From it 2 132 kV-lines run to Dragonera substation. Maó ( Mahon) 101,2 MW
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°55′55″N 3°50′1″E where the submarine cable to Mallorca starts. It ends at Cala Mesquida cable terminal at Cala Mesquida 39°44′19″N 3°25′38″E, 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°32′2″N 2°30′21″E. 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. he following 69 kV stations are in service.
