Most of New Zealand’s electricity is generated far from where the energy is used. Transmission carries high voltage electricity from power stations to industry and communities.
A robust transmission grid underpins reliable electricity supply and a competitive electricity market and connects renewable energy derived from rivers, hilltops and geothermal fields to end-users.
