Description: Data has been sourced from Transpower open data (https://data-transpower.opendata.arcgis.com/) and combines Transpower sites and structures, and is updated yearlyTranspower sites which include AC stations, DC Stations, Coms and Tees. Transpower owns and operates the National Grid - the high voltage transmission network connecting areas of generation with towns and cities across New Zealand. The National Grid is made up of over 12,000 km of transmission lines and more than 170 substations. Electricity is transmitted over the grid at high voltages (up to 400,000 volts) from power stations to local lines companies and major industries.Transpower Transmission Structures:Structures is a point dataset representing Transpower owned high voltage transmission structures. Construction types include; poles, towers (pylons), gantries and termination points. The location of each structure is the ground centre point of the structure. The structures dataset is updated ad-hocly. (Caveat - not all structures comprising New Zealand's electrical network are owned by Transpower).
