TransGrid has commenced the provision of Network Support and Ancillary Services (NSCAS) to the National Electricity Market (NEM), with the commissioning of a new voltage control device at Yass Substation, north of Canberra.
This is the first in a series of similar voltage control equipment to be commissioned in early 2014 at TransGrid’s Yass and Murray substations.
Transgrid, which is the owner and operator of the high voltage electricity transmission network in New South Wales, secured the contract to provide the NSCAS services to the Australian Energy Market Operator (AEMO) after a competitive tender process.
The company’s executive general capital program delivery Gerard Reiter said the first device was delivered well ahead of schedule and is providing significant savings to the NEM.
“By fast-tracking the delivery of the voltage control devices and making them available to AEMO, we expect to provide total savings to the market in the order of $30 million in the next five years,” he said.
“These benefits are expected to ultimately flow through to electricity consumers in NSW and the ACT.”
NSCAS are non-market ancillary services acquired by AEMO or transmission service providers, to maintain power system security and reliability and to maintain or increase the power transfer capability of the transmission network.
