When the federal and state governments were deciding on a location to announce a funding deal that will underwrite South Australia’s final leap to its remarkable goal of 100 per cent net renewables within the next three years, Port Augusta was the obvious choice.
The city at the top of the Spencer Gulf, like the neighbouring Whyalla, is everything that the climate deniers, the renewable naysayers, the conservative media and the federal Coalition say is not possible.
Port Augusta once played host to the state’s ageing and incredibly dirty coal generators. Whyalla was the subject of taunts from former prime minister Tony Abbott that it would be rendered a ghost town by a carbon price.
Now the two cities are host to thriving renewable energy hubs, new green industries and technologies that will help propel the state into a clean energy future.
And it is remarkable how little is actually known about the achievements of South Australia beyond its borders. Already it is at an annual average of 70 per cent renewables, and by 2027 it intends to be the first in the world to reach 100 per cent net renewables primarily through wind, solar and storage.
Just to be clear, that does not mean that it will consume only renewables. “Net” means that the amount of power it produces from wind and solar during the year will be equivalent to the amount it consumes. But it will still export and import as needs must.
It’s a stunning achievement, and still one that the naysayers insist is not possible. The state has become a globally significant testing ground in technologies – it hosted the first Tesla big battery that helped change the thinking on future grids around the world – and it is addressing and solving complex engineering issues that many experts thought were too difficult and some still say are insurmountable.
More importantly, it is doing this as a result of bipartisan policy. Labor kicked it off more than a decade ago by making itself the most welcoming state for wind and solar.
The Liberal state government set the target of reaching 100 per cent renewables by 2030. Labor is now back in power and has accelerated that target to 2027. It is marvellous what can be achieved when the coal lobby is removed and not pulling the strings of the politicians and public mood.
Despite all this, the achievements in South Australia remain largely ignored by the rest of the country.
The announcement by federal energy minister Chris Bowen and state energy minister Tom Koutsanstonis about the funding deal for a gigawatt of new wind and solar and 600 MW (2,400 MWh) of battery storage – to ensure the 100 per cent net renewable target is met – barely rated a mention in mainstream media outside the state.
Yet it is here, in Port Augusta, that federal Opposition leader Peter Dutton has decided should be one of seven sites – along with Collie, Liddell, Mt Piper, Loy Yang, Callide and Tarong – that should play host to their nuclear power plant proposals.
They were chosen, the Coalition tells us, because they are locations that still have or once supported coal fired power generators, and – they claim – would have available transmission capacity. But as Koutsantonis pointed out during his visit this week, that is simply not the case. That capacity has already been taken up by other projects.
“This site here where the Port Augusta power station once sat is now at capacity in terms of our renewable transmission lines to Adelaide,” he told journalists. “So the idea you can just plug in a nuclear power station here is just folly.
“I haven’t seen Peter Dutton here. I haven’t seen the Commonwealth Opposition here at all talking to the state government about their pretend plans for nuclear power in South Australia.”
Indeed, it is not surprising that Dutton has not shown up: South Australia is not just shining a path to the future, it is a real life repudiation of the folly of the federal Coalition’s nuclear plans, and the sheer nonsense of its claims.
Let’s remember that the Coalition and the conservative media’s nuclear arguments are based almost entirely around the assumption that wind and solar cannot power a modern economy.
South Australia proves them wrong, emphatically so. The grid is reliable, wholesale power prices are falling, and will continue to do so as it free itself from the yolk of fossil gas. Legacy industries are being revived by the growth of wind and solar, new industries are being established, and big business with big loads are being attracted to the state.
The once broke Whyalla steelworks, for example, has based its revival around plans for “green steel” underpinned by wind and solar, and BHP will power its giant Olympic Dam mine with a unique “firmed renewables” contract sourced from the state’s biggest wind project and a big battery.
The state’s transmission operator ElectraNet reports inquiries amounting to several gigawatts of new load from industries attracted to cheaper and greener power, and apparently not the least bit concerned about the scare campaigns that the lights will surely go out.
South Australia is already at the stage where enough rooftop solar is generated in the middle of the day to meet all local demand. That will soon occur in other states too, including Western Australia, effectively eliminating grid demand and requiring storage or new load or exports to soak up the excess.
As every major utility in Australia makes clear, the era of always-on base-load power is well and truly passed in such grids. South Australia has not just shut down its last coal generators, and is closing down its remaining combined cycle gas plants, which perform a similar role. The gaps will be filled by facilities that are fast and flexible. There is simply no room in the grid for an always-on nuclear plant.
“This site is taken. So I’m not quite sure where he’s planning to build this or how he’s planning to build this,” Koutsantonis said.
“If Peter Dutton was serious about what he was talking about, he would have come to us earlier and spoken to us about it, consulted with us. For whatever reason, he hasn’t even stepped a foot on this site to actually have a look at it.”
Bowen has been taking that message across the country. “This whole precinct’s being transformed … into a renewable energy hub, a green cement hub and a critical minerals hub,” he said at Port Augusta.
The next day, Bowen popped up in Lithgow, at the site of another mooted nuclear site, the Mount Piper coal generator, where the asset owner Energy Australia also outlined plans to build pumped hydro, a giant battery and to convert its coal plant into a “flexible” asset rather than an “always on” baseload asset in the interim.
“Traditionally Mount Piper has been a full-load, continuous load power station, and today it’s becoming much more flexible,” EnergyAustralia’s head of operations and projects Sue Elliott said. “It now operates during the day and seasonally depending on renewable availability in the market.
“We are progressing planning for a Lake Lyell Pumped Hydro Project … and we’re also planning a 500 megawatt, four hour Mount Piper Battery Energy Storage System right here on site to take advantage of transmission assets.”
As Bowen pointed out, this is real investment happening now, not some time in the distant future.
“I’m not sure if Mr Dutton and (Opposition energy spokesman Ted) O’Brien have been here yet, but they have a plan for nuclear power, which is at least 30 years away,” he said.
“They admit 2035 at its earliest; even that is wildly ambitious and optimistic and unrealistic. But that doesn’t fix the problems today.
“It doesn’t create jobs today. It doesn’t create investment today and, indeed, it will chill investment. It will stop people investing in the alternative plans because of the investor uncertainty created by having a nuclear plan, which is never going to happen – it’s a fantasy.”
South Australia, and its charge towards 100 per cent renewables, is very real. And worth talking about.
