Melbourne Water’s network of “mini-hydro” electric plants

Inside Melbourne’s secret suburban hydro power system, The Age, Darren Gray, 29 June 17 From the outside, it looks like a green shipping container on an industrial block in the suburbs. But on the inside, there’s plenty going on.

The box is part of a little-known but growing Melbourne Water network of “mini-hydro” electric plants generating electricity in suburban Melbourne, and in the hills beyond. With the addition of Melbourne Water’s 14th hydroelectric plant, a “mini-hydro” to be turned on on Thursday in Mt Waverley, Melbourne Water’s hydroelectric system generates enough power to supply more than 14,100 homes. Eleven of the plants are “mini-hydro” plants.

It’s a system that the water company hopes to expand further. “We are looking at up to 10 sites in our stage three program, which is in feasibility study now,” said Melbourne Water senior project manager Ian Royston, during a visit to the new Dandenong North “mini-hydro”.

This plant, which sits between two huge water storage tanks and EastLink, and about 40 metres away from the closest house, started operating in April. It is one of five new “mini-hydro” plants commissioned since December……

The hydroelectric power generated earns a decent return for Melbourne Water, which is paid by a power company for feeding electricity into the grid. Melbourne Water also earns money from trading LRECs, which currently trade on the spot market at about $76 per megawatt hour and are bought by companies to satisfy requirements under the renewable energy target. On current prices LRECs could generate about $3.3 million a year for Melbourne Water, given that most of the power it produces qualifies for the scheme…….

Melbourne Water’s counterparts in New South Wales, at Sydney Water, also have a range of plants producing energy. It has three mini-hydro systems on its network, at Prospect, Woronora and North Head.
“We also have eight co-generation systems in wastewater treatment plants, which take biogas from wastewater treatment and use it to create heat and electricity,” said Paul Plowman from Sydney Water.

“Sydney Water produces enough energy to power over 11,000 homes each year, reducing greenhouse gas emissions by over 70,000 tonnes a year, which is the equivalent of keeping 17,500 cars off the road for a year,” he said……http://www.theage.com.au/business/inside-melbournes-secret-suburban-hydro-power-system-20170626-gwyv5e.html
