Overview

Western Power is a state-owned electricity network company in Western Australia, responsible for building, maintaining, and operating the transmission and distribution network in the southern part of the state. It serves over one million customers.

History

Western Power Corporation was created in 1995 as part of the Government of Western Australia's reform of the State Energy Commission of Western Australia. The State Energy Commission had previously operated as the state's monopoly supplier of both electricity and gas. Its restructuring divided those activities between separate organizations: Western Power Corporation became the electricity utility, while AlintaGas was established as the separate gas supplier. The new corporation inherited an integrated role in Western Australia's electricity system. Its responsibilities encompassed the main stages of electricity provision, including generation, transmission and distribution. This made it a major public infrastructure organization and the principal government-owned electricity supplier in the state during the period from 1995 to 2006. The available reference material does not provide a detailed account of individual power stations, consumer brands, executives or specific commercial campaigns associated with the corporation. In 2006, the Government of Western Australia undertook a further disaggregation of the electricity business. Western Power Corporation was separated into four successor organizations: Western Power, Synergy, Horizon Power and Verve Energy. The new structure divided the formerly integrated utility model into distinct functions. Western Power took responsibility for the electricity transmission and distribution network, while generation, retail and regional electricity responsibilities were allocated among the other successor entities. This reform ended Western Power Corporation's existence as a single operating company. The historical corporation is therefore distinct from the later Western Power network business. Its significance lies in its position between the State Energy Commission's former monopoly structure and the specialized public electricity entities created in 2006. It was a state-owned Western Australian utility rather than a listed company or an internationally operating consumer brand.
