History of the National Grid book

Cover image of the History of the National Grid bookConnecting the Country: New Zealand's National Grid 1886-2007 was written by public historian Helen Reilly and sponsored by Transpower.

The book tells the stories of the early engineers, surveyors, linesmen and operators, and describes how their commitment to 'keeping the lights on' is still central to the ethos of running the National Grid today.

It tells how our country was wired, starting in the late 1800s: from the first government transmission line near Rotorua, to the planning and installation of HVDC and the development of system operations.

Connecting the Country contains photos, maps and diagrams which also tell a story, including documenting the changing safety standards.

Available in book stores throughout New Zealand.
