Siemens connects Majorca to power grid on the Spanish mainland

10/09/2007 | Siemens Power Transmission and Distribution (PTD) connects the resort island Majorca to the power grid on the Spanish mainland for the first time. The 250 kilometres (155 miles) long, 250 kV HVDC submarine cable link between Morvedre near Valencia and Santa Ponsa near Palma de Mallorca will allow power transmission of 400 MW at a DC transmission voltage of 250 kV as from May 2011. Thanks to this first access to the electricity market on the Spanish mainland, the peak load requirement of the islands can be covered by electricity imports from the European power grid, especially during the main holiday season in the hot summer months.
