Prospect Electricity was the state-owned corporation owned by the Government of New South Wales responsible for retailing electricity to consumers in the Greater Western Sydney region between 1991 and 1996. It was originally founded in 1957 as the Prospect County Council as a spin-off from the Sydney County Council which was responsible for supplying electricity to much of the eastern half of Sydney. As with the Sydney County Council it was initially controlled by local councils in the area.
