What is the national grid?What is the national grid?
• Transmission of electric power
• from large power stations
• to line companies, and
• to large industrial users.
• Includes the HVDC link.

Who are we?Who are we?• Electricity Transmission Heritage of NZ Inc
• Collecting and making available resources for study of the historical development of the New Zealand electricity transmission system
• Membership mainly drawn to date from Transpower staff, contractors, and consultants
• Strong sponsorship from Transpower executive
• Gathering also from non-transmission sources

How to tell the story? How to tell the story? • Depicting grid development
• The grid has grown from 1915 to today and is continuing to develop
• We have collected data going back to the beginnings
• A visual display of this growth
• Use Power Point to give one slide per year?
