Marlborough Lines takes it supply from the Transpower grid via three circuits to a single point of supply in the Blenheim suburb of Springlands.

Supply to Marlborough then radiates out to a number of very isolated rural areas including the Marlborough Sounds, Molesworth Station (New Zealand’s largest farm at the top of the Awatere Valley) and the Southern Marlborough coast; an area bordered by the Pacific Ocean on one side and the seaward and inland Kaikoura mountains on the other.
