TransGrid is the manager and operator of the high voltage electricity transmission network in the Australian state of New South Wales. TransGrid was originally established as a Statutory Authority on 1 February 1995, under the Electricity Transmission Authority Act 1994 after the break-up of the Electricity Commission of New South Wales .[1] "TransGrid" was originally the registered trading name of the Electricity Transmission Authority. Since its corporatisation on 14 December 1998, under the Energy Services Corporations Amendment (TransGrid Corporatisation) Act 1998, TransGrid has been the actual name of the corporation.[2]

On 16 December 2015 Australian-led consortium, NSW Electricity Networks, were confirmed as the lessee of TransGrid after being successful in their bid to take on a 99 year lease of TransGrid.[3]

Network

TransGrid operates the major high voltage electricity transmission network in NSW and the ACT, connecting generators, distributors and major end users.

TransGrid’s network comprises 99 bulk supply substations and more than 12,900 kilometres of high voltage transmission lines and cables. Interconnected to Queensland and Victoria, the network enables energy trading between Australia’s three largest states along the east coast making it the backbone of Australia's National Electricity Market.

The network operates primarily at voltage levels of 500 kV, 330 kV, 220 kV and 132 kV.

TransGrid's network also connects to 20 direct connect customers, including the four distribution businesses: Endeavour Energy, Ausgrid, ActewAGL, and Essential Energy.

TransGrid participates in the Australian Energy Regulator's (AER) Revenue Proposal Process, where a series of submissions between the Transmission Network Service Providers (TNSP), the AER and other interested parties are used to set the Maximum Allowable Revenue (MAR) for the TNSP for a five-year period.

TransGrid Telecommunications

TransGrid has managed an extensive telecommunications network for more than 15 years. The network is connected to the majority of NSW’s data centres and is currently expanding into Canberra and Victoria.

TransGrid’s Telecommunications network is the fifth largest optical fibre network in Australia, with the majority of the network's Optical Ground Wire (OPGW) strung above the electricity transmission network.[4]
