It’s grand final day in Australia, and awkwardly the State of Victoria risks a grid overload. A truckload of solar power will arrive at lunchtime that no one needs, and which has no place to go.
The largest single generator in Australia now is rooftop solar and it’s virtually uncontrollable. The geniuses running the national grid have subsidized solar panels and made electricity unaffordable at the same time, thus driving more householders into the arms of the solar industry.
So they’ve created an artificial market bubble — as all good communists do. We now have a 20 gigawatt capacity generator that mostly can’t be turned off, except by clouds or possibly Chinese cyberwarfare.
And where autumn and spring used to be the easy seasons, now Sunny spring days are diabolical too — hardly anyone needs their air conditioner or their heater at lunchtime, but solar watts are pouring in.
This was the situation yesterday in Victoria:
Again, the poor sods who built solar industrial parks (marked in red) have to curtail their production massively from 8am to 5pm. The red curve is supposed to look like the yellow curve. The missing red peak is wasted solar production.
As the yellow uncontrollable peak rises towards the black line (the total demand), the whole grid has a problem — more reliable cheap generators have to shut down to prevent the toxic excess electricity building up. Without the reliable generators, with their 500 ton turbines spinning at 3,000 revolutions per minute, (or 3,600 in the USA) the grid loses frequency stability, and spinning inertia, and the ability to cope when a cloud rolls over. The problem of excess solar at lunch time is also called The Duck Curve and has been known for years. It’s not like this snuck up and surprised anyone, yet here we are — courting disaster.
The ABC reported on this, but can’t bring itself to call this what is is — a “Solar Glut” dumped on the grid. Instead rooftop solar is a “juggernaut” and the grid faces a “low demand warning”, as if you personally are the problem, for not using enough electrons. Don’t blame the artificial pointless bubble of solar panels.
Rooftop solar ‘juggernaut’ risks grid overload as AEMO issues first-ever low-demand warning
by Daniel Mercer, ABC
Rooftop solar output has reached such enormous levels that authorities have begun issuing warnings about their ability to keep the electricity system from being overloaded at times.
In an extraordinary first this week, the body that runs Australia’s biggest energy market said the supply of solar power in Victoria threatened to overwhelm demand for electricity from the grid amid mild, sunny conditions.
It said Friday’s oversupply of solar was so acute that demand for power from the grid would fall below a threshold critical for keeping the electricity system on an even keel.
Even the AEMO (the Australian Energy Market Operator) calls it a minimum system load notice – not a solar surge, or a renewable overload.
And despite the toxic excess of solar panels, and that we’ve known this day would come, in true Soviet fashion, we’re still installing as many as we can (see below). The trainwreck continues.
The relentless rise of solar PV in Australia.
That would stop dead in its tracks if householders had to pay fair costs for the frequency stability, the back up power, and the storage.
The solution, according to government experts, is not to have a real market and accurate prices, it’s to give more powers to some bureaucrats so they can order battery owners to discharge before lunch and be ready to soak up the dangerous excess at midday. The battery owners don’t like that, but like an anaconda, the government gradually tightens its grip until the free market is dead. The other “solution” is to add controllers to home solar panels so the government can switch them off (which is starting to happen in South Australia and Western Australia). Solar panels owners don’t like that either, but they were sold rainbows and fairy cakes that no one could deliver.
The communist quislings complain that the market is failing us and needs more governance. But the truth is, the overlords destroyed the free market long ago. The people want reliable electricity, and if they were allowed to choose reliable power over renewable energy, the problem would solve itself.
Meanwhile, grid managers surely pray for cloudy days. Soon, some bright spark is going to suggest cloud seeding for grid stability.
UPDATE: The grid demand fell to 1817MW in Victoria, and survived but prices spiked to minus $367 today during the low minimum solar belly of the duck.
