Australia’s most advanced renewable grid is its most secure, but NSW must scramble as it nears “no coal” scenario.

 South Australia, the most advanced renewable grid in the country and even
the world – thanks to its unrivalled near 75 per cent share of wind and
solar – is also the most secure, according to a major new report on the
state of the energy transition.

The Transition Plan for System Security,
published on Monday by the Australian Energy Market Operator, identifies
South Australia as the only state grid which is not facing a system
strength deficit in coming years.

That’s largely because South Australia
went first, and it went hard and fast. Its last coal fired power station
closed in 2016, and because it has such a high percentage of wind and
solar, as well as rooftop PV, it has had to deal with the issues around
frequency control, inertia and system strength before other states. South
Australia, the most advanced renewable grid in the country and even the
world – thanks to its unrivalled near 75 per cent share of wind and solar
– is also the most secure, according to a major new report on the state
of the energy transition.

When the new transmission link to NSW is complete in 2027, South Australia will
be the first in the world to be able to run its gigawatt scale grid at
times with “engines off” – i.e. no gas plant required for bulk power
or system security – as it nears or even achieves its target of reaching
100 per cent net renewables.
