A 10-year program to provide a safe and reliable power supply to Warwick in the Southern Downs region in Queensland is now complete. The program included a new substation and sub-mission line refurbishment.
Queensland Minister for Energy, Mark Bailey, said the $33 million East Warwick substation project to replace the original substation meant the entire backbone of Ergon Energy’s network supplying the region had been upgraded in the past decade.
“The original East Warwick substation had served the community well since 1954, but a modern replacement was needed to meet the future requirements of residents and businesses,” Mr Bailey said.
“The substation, at the intersection of Percy and East streets, supplies power to about 5000 customers in the town and in rural areas to the east of Warwick.”
Mr Bailey said the project generated more than 40,000 hours of labour work for local tradies and contractors during the 2.5 year construction.
“Ten years ago, the Warwick region was one of the worst-performing parts of Ergon’s network and customers experienced an unacceptable number of power supply interruptions during severe storm seasons,” Mr Bailey said.
“Earlier projects such as the refurbishment of one of the sub-transmission lines from Toowoomba to Warwick and rebuilding the second one as a new, high-reliability line, plus an upgrade to the West Warwick substation, turned that around.
“The recent completion of an upgrade at the Warwick bulk supply substation and now the total rebuild at East Warwick mean the community can be confident of having a safe and reliable power supply for years to come.”
Mr Bailey said the benefits of many of the projects extended to other parts of the Southern Downs supplied from the Warwick bulk supply substation.
“These customers have also benefited from the refurbishment of the Warwick to Stanthorpe 110kV line and the upgrading of the East Stanthorpe 33kV line, so the network has more flexibility and delivers improved reliability and quality of supply in the Stanthorpe region,” Mr Bailey said.
“New 25MVA transformers have the capacity to meet future demand on the network and also enable some load that had been temporarily transferred to West Warwick substation to be returned.
“The substation also has new capacitor banks and circuit-breakers and the start of the feeder lines out of the substation have been replaced.”
