Perenjori, situated in Western Australia’s Wheatbelt region, is supplied by the a 33kV long rural distribution feeder. Perenjori customers were experiencing lower reliability of supply compared with most customers within Western Power’s network. Decmil and joint venture partner Balance Utility Group were awarded a contract to supply, deliver, install and maintain a Battery Energy Storage System (BESS) to alleviate the poor reliability of supply experienced by customers in Perenjori.
Scope of Work
The scope of works included the supply, delivery, installation and maintenance of a fully functional utility scale BESS connected to Western Power’s 33kV distribution network. Works included integration studies, site preparation, installation and commissioning and servicing of the system.
The BESS turnkey solution was successfully integrated into the existing network ensuring compliance with Western Power’s Technical Rules, Western Power network planning guidelines, protection and SCADA requirements, as well as all applicable standards and regulations.
Since commissioning in July 2018 the system has achieved no outages.
The BESS achieved its main objective of improving reliability of power supply to customers in Perenjori by reducing the number and duration of outages these customers experienced. The BESS provided approximately two hours of backup power supply in islanded mode to Perenjori customers in the event of loss of normal network supply.
