TransGrid is the operator and manager of the main high voltage electricity
transmission network in NSW, ACT and other areas of the National Electricity
Market, connecting generators, distributors and major end users.
Our core role is to provide safe, reliable, sustainable and affordable transmission services to NSW,
the ACT and other areas of the National Electricity Market.
TransGrid’s network carries bulk electricity from generators in far west NSW through 13,000
kilometres of high voltage transmission lines, underground cables and substations. The high voltage
electricity is then converted to low voltage electricity suitable for household consumption at
substations closer to homes and businesses.
