Transmission

Transmission

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.

Delta has the expertise in the design, build, repair, testing, monitoring and maintenance of electricity networks.

Whether you are upgrading or maintaining existing infrastructure or installing new transmission, Delta has the specialist technical expertise and technology for the job.

Plus, you can rely on us to provide a full range of services including design, civil construction, fibre-optic communications, earthing, testing and condition monitoring.

We improve network reliability for our customers by applying smarter thinking and the right technology.
