Red Eléctrica de Espana (REE) has contracted Siemens Power Transmission and Distribution (PTD; Erlangen, Germany) to deliver two converter stations for the new high-voltage direct-current (HVDC) transmission link between Morvedre near Valencia and Santa Ponsa near Palma de Mallorca, connecting the Balearic island of Majorca with the Spanish mainland.

From May 2011, the 250-km (155-mile) long, 250-kV HVDC submarine cable with a power capacity of 400 MW will provide the resort island with environmentally friendly and low-loss power supply from the Spanish mainland.

The Siemens scope of supply comprises the delivery and installation of the HVDC converter station on a turnkey basis, as well as gas-insulated switchgear and a highly integrated switching station for connection to the network. The order also includes the core components such as thyristor valves, converter transformers, smoothing reactors, protection and control systems and the ac and dc filters.
