A $12 million project at Powerlink’s Tully Substation has been completed, further securing power supply to the State's north.

The project involved replacing secondary systems at the substation, which supplies high voltage electricity to North and Far North Queensland.

The works supported up to 28 jobs, further securing supply to businesses and households across the region and were conducted over a number of years to maintain reliable supply to customers.

Secondary systems provide protection, control and communications equipment to operate the transmission network and prevent damage to primary plant in the substation such as transformers.

Powerlink Chief Executive Merryn York said the upgrade was a cost-effective solution to maintaining the network and boosting Powerlink’s capabilities in responding to network issues.

"Upgrading secondary systems help to avoid or delay the development of new infrastructure," Ms York said.

"Powerlink’s asset management approach is ensuring reliability of the network at the lowest long-term cost to our customers.

"We take our role in helping to deliver electricity to four million Queenslanders very seriously and the completion of this project is another step in delivering a safe and reliable network to North and Far North Queensland."
