Australia’s ‘Wind Power Capital’ – South Australia – Becomes the ‘Blackout State’

 

January 7, 2017 by stopthesethings

 

 

Once heralded as Australia’s ‘wind power capital’, South Australia has become renowned worldwide for its power pricing and supply calamity: routine load shedding and statewide blackouts are now the norm.

 

The mass blackout on 1 November 2015:

 

The 28 September 2016 blackout:

 

 

And the 1 December 2016 blackout:

 

 

 

– all had one thing in common: a precipitous collapse in wind power output.

 

That data is collected from the AEMO and helpfully compiled by the boys at Aneroid Energy. For anyone with a passing interest in South Australia’s current wind power calamity, a few clicks is all it takes to get behind wind industry spin and political obfuscation.

 

While there is no question that storm damage to transmission lines causes interruption to any power supply, South Australia is a place that relies heavily on the weather for its power supply. By way of contrast, neighbouring Victoria was battered by the same series of thunderstorms that buffeted SA but suffered hardly any power interruptions – in coal-fired Victoria, the blackouts were brief and isolated – more minor irritant than the life-threatening disaster that played out in wind ‘powered’ SA.

 

In both the ABC and The Australian articles reference is made to wind speeds of ‘90km and 120km per hour’ reaching ‘126km/h recorded at Port Augusta’.

 

As we have pointed out time and time again, these things will not operate when wind speeds exceed 25m/s or 90km/h.

 

That unassailable fact helpfully appears on German turbine maker, Siemen’s website – which has this to say about the automatic shutdown of wind turbines when wind speeds hit 25m/s (90km/h):

 

Nature presents us with different kinds of challenges. High wind can create extremely high loads, and as a result wind turbines are normally programmed to shut down if the 10-minute mean wind speed exceeds 25 m/s. This may pose a significant challenge for the grid system – for example, if turbines in large wind farms shut down simultaneously.

 

It was precisely that feature that saw wind power output collapse on 28 September 2016, as wind speeds reached gale force across the State.

 

So with a little help from Aneroid Energy, let’s have a look at what SA’s 18 wind farms with a notional capacity of 1,576MW were doing during South Australia’s most recent statewide blackouts, starting with 27 December:

 

According to the ABC, power disappeared for most in SA with the storm that hit ‘late on Tuesday night [27 December] and into early Wednesday morning [28 December]’.

 

At around 11pm, SA’s wind power output was, for a few minutes, clocking a solid 1,200MW. However, within the space of less than two hours, output had collapsed by a whopping 850MW to around 350MW. Bear in mind, by way of comparison, one of South Australia’s last remaining base-load power plants, GDF Suez’s Pelican Point CCGT plant has a capacity of 485MW.

 

Here’s what occurred on 28 December:

 

 

On 28 December a rapid weather driven climb from 350MW to 1,300MW is followed by a meandering collapse to around 50 MW by midnight.

 

On 29 December, the picture again looked more like a roller-coaster designed by a madman, rather than anything associated with the secure and reliable supply of electricity.

 

While the same band of morally bankrupt idiots that pretend to run South Australia continue to defend the indefensible – treating anyone with the temerity to point to wind power as a possible cause of the most erratic power supply anywhere in Australia – grid engineers know different.

 

All things equal, a functioning grid requires stable, synchronous power generation which is something that wind power is not and will never be.

 

Moreover, wind turbines do not generate power independently of a stable supply delivered to them from the grid – generated by conventional sources: kill the grid supply and wind turbines go into lock-down; and, once there, are incapable of adding a single watt to the grid until conventional power sources have re-energised the grid – what’s termed a ‘black start‘ – only nuclear, fossil fuel or hydro generators have ‘black start’ capability.

 

With all eyes on SA and its clearly failed wind power experiment, we’ll re-run an earlier analysis, starting with this insight from the AEMO about what’s required to maintain the integrity of a functioning electricity grid. [Note that the term Power Electronic Converter (PEC) is the euphemism used for wind and solar power generation.]
