"When Chris Davies, the head of future energy systems at the Australian Energy
Market Operator, was at university, he says there were just 100 rooftop solar
systems in the country. And even more recently, the idea that you could have
more than 20 to 30 per cent wind and solar on the grid at any one time was
laughed out of the room
But the energy market is changing rapidly, and so too is the understanding of
the engineering around renewables and inverter-based technologies.
So much so, that records once considered impossible have been steadily falling
in recent years. First there was 100 per cent instantaneous wind and solar on a
megawatt scale grid on Australia’s King Island, then in the slightly larger
Hawaiian island grids of Kaua’i and Maui.
Ireland has since reached 75 per cent penetration of variable renewables, as
has the Texas grid, which is double the size of Australia’s National
Electricity Market.
But even more spectacularly, in two multi gigawatt-scale local grids, Western
Australia has reached 84 per cent and South Australia 92 per cent wind and
solar, the latter even when a network issue meant it was effectively isolated
from other state grids.
South Australia has since gone one better than that when, on New Year’s Eve
last year, the amount of rooftop and distributed solar exceeded state demand
for a brief period, although the state was able to export excess production at
the time.
“This is purely phenomenal, absolutely phenomenal that we’ve reached this
point,” Davies says. “When I was at uni, there were 100 houses in Australia
that had solar on their roofs.
“So to be at a point where we could be supplying all the electricity from
rooftop solar is just unbelievable. And what makes this possible is the
engineering work and the policy work in South Australia to make that power
system secure and to give us confidence in the performance of those devices.”"
