Project Comments The project consists of two monopoles and two separate metallic return conductors that were added to replace the original integrated return conductors in the original cables. A fault in the system led to the interconnector having a reduced capacity from September 2010 and from December 2012 to 2015 the capacity was halved. Repairs to this were conducted by laying new low voltage cables, metallic return conductors, and thus replacing the original return conductors, called the Moyle Returns Project.
