Rebuilt substation to complete power upgrades for Warwick

Ergon Energy’s 60-year-old East Warwick substation will be rebuilt in a major project that will complete the refurbishment of the key infrastructure on the electricity network supplying the Queensland town.

The corporation’s acting general manager service delivery Craig Harris said the existing substation had served the community well since 1954, but a modern replacement was needed to meet the future requirements of residents and businesses.

“One of the existing transformers will be removed and a new transformer brought into service before the process is replicated with the second transformer,” Mr Harris said.

“The new 25MVA transformers will have the capacity to meet future demand on the network and also enable some load that has been temporarily transferred to West Warwick substation to be returned.”

A concern for Ergon Energy is the aesthetics of the redesigned substation, which Mr Harris said will be more appealing to neighbouring residents due to the indoor design and landscaped buffer zones.

“The revamped version will feature two modular buildings to house the new switchgear,” he said.

“The substation will also have new capacitor banks and circuit-breakers and the start of the feeder lines out of the substation will be replaced.”

This work was the last component of a series of projects by Ergon Energy to improve the reliability of supply to Warwick and other parts of the Southern Downs.
