An Australian consortium is offering to buy 110GWh of energy between its members, which would require a renewable energy plant with about 15 wind turbines or 250 000 solar panels.
Councillor Arron Wood from the City of Melbourne said the project emerged from the council’s target to source 25% of its energy from renewables by 2018.
The council commissioned a study of how much renewable energy would be available from solar panels on City of Melbourne rooftops, and it only amounted to about 2% of what they needed to meet the target, he said.
“Particularly in a dense environment like the City of Melbourne, where you have many tall buildings, it’s unrealistic to think that rooftop solar is going to deliver all of that,” Wood said. “So what we’re going to require, is installed renewable energy outside the municipality. We quickly realised we’d need large-scale renewables to play a strong part in that.”
One of the roadblocks for some utility-scale renewable projects has been difficulty in selling long-term “power purchase agreements”, which would secure their profitability. Wood said this model lifts that roadblock, allowing projects that are otherwise completely ready to be built.
