Under the sun: Australia's largest solar farm set to sprout in a Queensland field






A sea of glass panels may soon be sprawling across a paddock in
Queensland’s Darling Downs cranking out two gigawatts of energy – 100
times more than the largest solar farm in Australia today – and a former
top flight barrister is the unusual shining light behind its
development

As a barrister acting in some Australia’s biggest defamation cases,
Angus Gemmell encountered power in various forms: political, military,
celebrity.



He killed off rumours bedevilling rising political stars in Canberra.
He acted for defence intelligence chief Frank Lewincamp against the
Bulletin over stories on Indonesia and the East Timor crisis, in a case
where generals Peter Cosgrove and Angus Houston gave evidence. He won
the largest damages ever awarded by a judge, $385,000, for rugby league
player Mark McGaw over false Today Tonight stories of domestic violence.

But after seven years as a barrister, Gemmell decided to leave the
intellectual challenges of “other people’s problems” behind, hang up his
wig and gown, and devote himself to power in a purer form.



Gemmell set up Solar Choice
– a solar project broker and consumer comparison service – while still
in his legal chambers and he is now the proponent of what stands to
become the largest solar farm in the country, perhaps the world.

A sea of glass panels, to be located at Bulli Creek on Queensland’s
Darling Downs, could be capable of cranking out two gigawatts of power
within eight years. That is equivalent to one fifth of the current total
renewable energy target for the entire country in a single power
station. It is also more power than any coal fired station in Queensland can currently muster.

“Excellent sunlight hours” are just one reason why Bulli Creek is ideal for a large-scale solar farm, Gemmell says.


It is also grazing land – meaning no prime cropping land need be sacrificed – and is flat, treeless and has no neighbours.


Crucially, Bulli Creek is close to a major transmission node in the
national electricity grid, a 330 kilovolt substation, perfectly located
to send power around the country.



“There’s a surprisingly small number of sites (in Australia) that have everything all aligning at once,” Gemmell says.


Factors seem to be likewise aligning in solar power’s favour more
broadly, although a few things still need to fall into place for the
likes of Gemmell.



Investment banks are leaning away from coal fired stations towards
large scale renewables, he says, while the electric car market is
driving rapid innovations in battery storage that are an automatic
fillip to the solar energy industry.



Those advances are essential in helping the solar industry “nullify
the argument principally raised against renewables as being
intermittent, and deliver smooth power throughout the day and night,”
Gemmell says.



Battery storage is what Bulli Creek will also need to reach full
capacity and most effectively integrate with the nearby substation.




The FRV Royalla solar farm near Canberra is currently Australia’s largest at 20mW. The farm is expected to generate an average 37,000 MWh of renewable energy each year for the next 20 years and will meet the needs of 4,500 Canberra households.

A report this week by a German think tank Agora Energiewende predicted solar would be the cheapest form of energy in a decade.


Gemmell, citing deals for 260MW projects in Dubai and power purchase
agreements at US 5.84c a kilowatt hour, agrees. “It’s now foreseeable
that solar will in the next decade be able to outcompete a very old,
fully depreciated coal-fired generator that chugs along at 3 or 4 cents a
kWh.”



“Obviously once a project’s been constructed, the cost of fuel is
free, it’s sunlight, and Australia is wonderfully geared to some
visionary projects to harness those benefits of cheaper, bountiful,
reliable sources of power,” Gemmell says.



“We’ve got abundant space, modern infrastructure across the longest
continuous grid on the planet, from Cape York to Tassie, and amongst all
that space is plenty of sunshine.”



Big energy players like AGL, who are still buying coal-fired power
stations, are nevertheless also moving into solar farms and other
renewables, which Gemmell says will inevitably quicken.



“I think eventually they’ll realise you can’t hold back the forces of
economics forever and, even though we’re perhaps more so than any other
country on the planet heavily wedded to coal, the economics of large
scale solar is on the right side of history,” he says.



“It’s not a matter of if these projects will be built but when.”


In large-scale solar’s infancy, however, market signals from government matter, even more so in their absence.

Investors have reviewed the Bulli Creek project but Gemmell says the
commitment to bring in “the big funds” still awaits clarity from the
Abbott government on the status of Australia’s renewable energy target
(RET), which has been under review for a year.



The RET is also a key driver of what kind of power purchase agreement
Bulli Creek can secure from a big Queensland electricity retailer like
Energex or Origin.



“Hopefully we won’t be the first country in the world to diminish our
renewable energy target. Most countries are increasing theirs,” Gemmell
says.



“We would prefer as an industry no deal rather than a bad deal.


“But if there’s a reasonable compromise at least we know where the
goalposts are to kick the ball. At the moment we’ve got the ball ready
on the mark to kick it, we’ve just been waiting for some time now to
know where the goal posts are going to be.”



In the meantime, Solar Choice will spend the next six to nine months
working with the wholesale network owner Powerlink on the right way to
connect the solar farm to the grid.



After that, the contract with the energy retailer is the final milestone before construction, due to begin next year.


The solar farm gained formal planning approval from Toowoomba
regional council last month in what Gemmell said was “a wonderful
tangible milestone for the project”.



Asked if the urgency of responding to climate change meant that, as one commentator has suggested, someone has to get rich, Gemmell responds: “No one’s suggesting that we need to take a communist approach to this.”


“It’s a free market and those who are able to be the first to
innovate and embrace the change and to move with it should do well and
they shouldn’t be punished for doing so,” he says.



“Obviously there’s a great amount of opportunity out there but it
does take a fair bit of boldness as well to be able to participate in
this paradigm shift.”
