Power stations, transmission lines, terminal stations, transformers, substations, and all of rest of electrical engineering, from Victoria and further afield.

A history of gas fired power generation in Victoria

The dinosaurs in the Australian fossil fuel industry have been fighting the rise of renewable solar and wind power, with a recent tactic being the promotion of natural gas as a ‘clean’ fuel for the transition from coal. This is the story of how Victoria has used natural gas for the generation of electricity. In […]

Backup generators and the 1982 New South Wales power crisis

In Australia power generation has become another front in the culture wars, as backers of coal fired power stations fight the growth of renewable solar and wind power, blaming them for any minor power outage. But back in 1980s New South Wales far worse power restrictions were put into place – and failed coal fired […]

A history of synchronous condensers in Victoria

In the past decade wind and solar generation has been displacing older coal fired power stations in Australia, with the stability of the electricity grid coming into question. One of the proposed solutions is something called a synchronous condenser – a technology that the State Electricity Commission of Victoria took advantage of fifty years ago. […]

High voltage power lines to nowhere

On the outer eastern edge of Melbourne there is a curious piece of infrastructure – a high voltage power line to nowhere. So why was it built, and why is it currently sitting idle? Running south-west from Coldstream to Templestowe, via Chirnside Park, Wonga Park and Warrandyte, I was first tipped off to the existence […]

When high voltage transmission line cross over

Out on the western edge of Sydney I came across a curious sight – not one, but two sets of high voltage transmission lines crossing over each other. They were located either side of Luddenham Road in the semi-rural suburb of Orchard Hills. One set to the east, the other to the west. This is […]
