Western Power is upgrading more than 75 distribution transformers across WA’s main electricity network ahead of summer in a bid to improve network resilience.
This work forms part of an overarching program to replace 143 distribution transformers over two years, to bolster the network through the hotter, higher usage periods.
Western Power Asset Operations Executive Manager Zane Christmas said improving network resilience would help minimise the duration and number of unplanned outages caused by severe weather.
“Over the last few years, with the help of new technology, we’ve refined our forecasting to better map the demands on our network infrastructure,” he said.
“While these assets were historically fit-for-purpose, the significant growth in demand from additional customers, as well as the amount of power drawn from modern appliances, has increased the need for transformers to better meet this need.”
Western Power is continually working to improve network resilience with about $1 billion invested annually in network upgrades and maintenance to manage safety, reliability, and environmental risks.
As the risk of heatwaves and bushfires increases, Western Power has taken steps to ensure the network is as prepared as much as possible for severe weather.
Western Power’s summer preparedness activities also include vegetation management, bushfire prevention, and forward-planning for feeder upgrades at key locations.
