Victoria is driving down Blackout Drive. They have reports from South Australia up ahead, they know where the road goes, but the state is paying for the first class ticket on a trip to RiskyGrid.
Victoria has 5.7 million people, over three times bigger than South Australia. Right now SA relies on the Victorian grid stability to keep running, and gets up to 800MW of reliable electrons from the state-next-door. But Victoria wants to add more wind power — theoretically the equivalent of a big coal fired plant (like Hazelwood).
Tom Quirk and Paul Miskelly looked closely at the numbers and patterns and see the writing on the wall. To help expensive, unreliable, intermittent green energy survive the government subsidizes it by around 9c per KWhr (bear in mind the wholesale rate for coal fired power is 3 – 4c per kWhr.) The government also demands retailers have a 12.5% mix of renewables, and that they accept most electrons from wind power whenever and wherever it is available. This strange anti-free market rule is called “nondispatchable” power, meaning the system can’t just throw it away if there is any demand at all. Whereas coal […]
Boondoggle: How Ontario’s pursuit of renewables broke their electricity system
Financial Post, Terence Corcoran
The Green industry has done over Ontario consumers. Government control of the electricity market was “cheered on by a growing industrial complex of wind and solar promoters backed by a large contingent of financial firms, big name consultants, fee-collecting law firms and major corporations. All were anxious to play a lucrative role fulfilling renewables objectives”.
Ontario was going to be the North American leader in renewable energy. It would save lives, create jobs, cost nothing, but instead the electricity bills have doubled, no lives were saved and the only jobs created were temporary (and almost certainly cost more jobs in other areas due to high electricity costs). The only “success” for the extra wind and solar power that’s locked into the grid is that it has “saved” some meaningless CO2 emissions at the exorbitant, flagrant cost of $250 per ton. Green energy was supposed to save $4.4billion in healthcare and other costs, but virtually none of that materialized.
Costs have gone from 5.5c a KWh in 2006 to 11c KWh in 2016. (How is it still so incredibly cheap ask Aussies? We are the largest […]
Finally, the gritty info we’ve been waiting for: The Australian Energy Market Operator’s (AEMO) preliminary report. The message here is of how a combination of both transmission towers failing and probably the auto-shut-off of wind farms combined in 12 seconds to crash the South Australian system. It’s looking awfully bad for the wind industry. The AEMO pins the crash on the sudden reduction from the wind generators, but stops short of declaring why they dropped power so suddenly. Was it the auto-shut-offs, lightning strikes, a software glitch, turbine failure, or was it a key transmission line that broke? Reneweconomy is about the last-man-standing trying to defend the wind industry in Australia. Giles Parkinson argues it was the third transmission line that took out some wind generation.
Even if the third transmission tower took out two “farms”, the fragility of wind-dominated grids is on display. And above and beyond this, South Australian electricity is a management debacle. The only question is, which mistake was the worst: Is this is epic indulgence of running the wind farms flat out in a storm only to trigger a blackout with their auto shut offs? There’s a compelling case, but there are tenths or less […]
Australians are going to be talking about this for weeks. Indeed, the SA Blackout is the stuff of legend.
The Greens are blaming coal (what else?) for causing bad storms and blackouts. Forget that Queensland gets hit with cyclones all the time and the whole state grid doesn’t break. Some greenies are also raging against “the politicization” of the storms. Yes, Indeedy. Go tell that to Will Steffen.
We are not being told the whole story. We do know that South Australia has the highest emphasis on renewables in the world. It also has a fragile electricity network, and wild price spikes to boot. (Coincidence?) The death of a few transmission towers should not knock out a whole state, nor should it take so long to recover from. The storm struck worst north of Adelaide near Port Augusta but the juicy interconnector from Victoria runs in from the south, and goes right up past Adelaide and most of the population. Why couldn’t the broken parts of the system be isolated?
Digging around I find ominous warnings that while the lightning and winds probably caused the blackout, the state of the South Australian grid appeared to be teetering on the brink, […]
