TransGrid Easement Guide

What is an easement?
An easement is a ‘right of
way’ along the route of a
transmission line. Easements
vary in width depending upon
the operating voltage and
design of the transmission
line. Generally speaking the
higher the voltage, the larger
the easement required. Some
typical easement widths and
structure designs are shown
in the diagram at the bottom
of this page.
Easements are acquired for two
essential reasons. The first is so
that TransGrid can construct,
reconstruct, operate and
maintain its lines. The second
is to ensure protection of the
public by controlling activities
under or near the line that may
create an unsafe situation.
