Renewables and solar as a source of reliable power increases on Australian farms, as farmers share the load – ABC News


Dairy farmer Michael Cains remembers clearly the wet and stormy night that he decided to install renewable energy to improve his power reliability.

His power had gone out on his Canowindra property in Central West NSW, and his energy provider had told him it would take three days to get it back on.

“I headed down the hill to grab the 20-kilovolt generator, revved the crap out of my ute getting up the hill. I’m drenched. I stick the generator into the system just as the power comes back on,” he said.

He bought solar panels and a battery using a government grant and a loan from the Rural Assistance Authority.

He now trades that power with neighbouring businesses using a ‘peer-to-peer’ system.

“We can use our own solar first, fill up the battery second, trade it between the house and the bar/cafe we’ve got in the middle of Robertson, and when we’ve got excess energy, we can send that to Rosnay (a vineyard), or The Pines (a bed and breakfast).”

Mr Cains is not the only dairy farmer doing this, with a 2020 survey by the peak industry body finding that 71 per cent of farms installed at least one type of renewable energy between 2015 and 2020.

Dairy Australia said the trend was well up from 44 per cent and mostly included solar panels, water heating, and variable speed drives, which regulate energy flow into machinery to make it more energy efficient.

While data across the entire agricultural industry is not available, it is clear many are making the switch.

Mr Cains’ neighbour, winery and orchard owner Sam Statham has installed 87 solar panels to power his property and contribute to the ‘peer-to-peer’ system.

Mr Statham said he generally irrigated during the day when the solar pumps work best.

“That’s when the plants need water, but that’s also when the water will evaporate the most from the heat from the sun, so what we did was put our irrigation dripper tubes underground in the middle of the vine row,” he said.

Further north in Queensland, Darling Downs cotton and chickpea producer Don Baartz used a ‘green loan’ from a major bank to spend $37,600 on a solar system to run his 18-kilowatt bore pump.
