Why DC cable transmission?
• Cook Straight electrical transmission uses DC cables (1961)
• Two small DC cables versus three large AC cables (30 km)
• Cables are armour plated and buried over one metre deep into harbour floor
• Power ranges from 0 to 200 MW to 0 in 6.5 hours
• Charging DC cables does not present a limitation, by comparison to AC

DC-AC converter and substation
• Sound-proof building50 x 30 x 10 metres
• Underground cables link indoor
converter to outdoor substation
• Substation fenced25 x 30 metres
• Transmission via overhead lines to Wellsford and Helensville (and/or other options)
