Supporting a secure power supply for the Territory's future

Published: June 2, 2016 - Updated: July 19, 2017

Power and Water Corporation is responsible for electricity transmission and distribution as well as water and sewerage services to an estimated 243,700 people across more than 1.3 million square kilometres of the Northern Territory.


The main switchboard (MSB) at the Hudson Creek System Control facility was built and commissioned in 1987. A recent preventative maintenance investigation identified components which had become superseded and should they fail, would require shutdown of the substation to integrate replacement hardware. Updates to electrical drawings and a need to meet increased power demand were also highlighted as priorities.


SAGE Automation was engaged to replace the existing MSB, including the control system for standby power in emergencies, and provide new electrical documentation to support the current status of the system control facility moving forward.


PWC Facilities Manager Graeme Carloss explains why this work is important.

“Having updated equipment, controls and associated documentation, significantly reduces our risk of downtime for System Control and assists in
securing power generation and distribution across the entire Northern Territory into the future.”
