suppliers have a primary
objective to provide a safe, reliable and adequate supply of
electricity at the lowest practicable cost. Electricity is produced
in power stations and is transmitted in bulk over a statewide network
of transmission lines to substations where it is sold to County
Councils for distribution to customers.
transmission network includes
lines operating at . voltages ranging from 33 000 volts (33 kv) to
500 000 volts (500 kv).
You must obtain
permission from your energy provider before you
construct any improvement of carry out an activity on the easement.
WHAT IS AN
is essentially 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
are acquired for 2 reasons:
- to protect members of the
public by controlling activities under or near the line which could by
accident or otherwise, create an unsafe situation.
- to enable the power authority
to construct, reconstruct, operate and maintain its lines.
