HVDC Moyle
The HVDC Moyle Interconnector is the HVDC link between Auchencrosh, South Ayrshire in Scotland and Ballycronan More, County Antrim in Northern Ireland, which went into service in 2001. It is owned and operated by Mutual Energy.
The HVDC Moyle has capacity of 500 MW. It consists of two monopolar 250 kV DC cables with a transmission capacity of 250 MW each. The converter stations are completely equipped with light triggered thyristors.
The converter station at Auchencrosh is connected via a 64 kilometres (40 mi) single-circuit 275 kV overhead three-phase AC line, which is installed on delta-type pylon with Coylton substation where the connection with the high voltage grid of Great Britain takes place. As line connection a 63.5-kilometre (39.5 mi) long monopolar cable is used, of which 55 kilometres (34 mi) are implemented as submarine cables.
Mutual Energy is a mutual company which manages energy assets for Northern Ireland's energy consumers.
As of October 2011, the interconnector was out of service, repair efforts were being made, and the cable became operational again with 450 MW in February 2012.
Intraday capacity trading is not available, but is being discussed.
