Recently the National Electricity Market in Eastern Australia had to be temporally suspended due to a short-fall in generation.

Now, the new Federal Government, that came to power on a promise to substantially cut power bills, has had to concede, that instead, there will be substantial price increases.

In part, they are blaming the war in the Ukraine; the consequent sanctions against Russia; and Russian retaliation. 

During the election campaign the Shadow Minister for Climate Change and Energy repeatedly asserted that the solution lay in increased wind and solar generated electricity, that he also repeatedly asserted were cheaper than fossil-fuel generated electricity. 

Yet, now the solution is said to lie in 'temporary' price caps on the spot-price of steaming coal and gas (mainly methane).  

An observer from another planet might ask: why the global demand for steaming coal and gas is still rising (and with it their price) when wind and solar are, allegedly, so much cheaper? 

Meanwhile, last July (2022) Wendy and I had occasion to visit the town of Rønne on the small Danish island of Bornholm. There on the quayside were a dozen huge wind-turbine nacelles.

As I had some spare time on my hands, I looked on-line and discovered that they were Vestas V174-9.5 MW units for installation off the coast of Germany, for either the Baltic Eagle or Arcadis Ost 1 project. I compared the published project costs with those of other large scale energy projects around the world.

You can read my analysis here (Europe 2022 - Part 1 - An Energetic Diversion). 

Suffice it to say, that wind-generated electricity is not price-competitive with modern fossil generated electricity - it's just a lot cleaner.

Most importantly: nor is off-shore wind anywhere near price-competitive with the latest nuclear generated electricity (on a dollar per unit of installed capacity basis), as nuclear power has a similar cost per Watt of capacity but doesn't require additional batteries or pump-storage to satisfy fluctuating demand.

The present situation on the east coast of Australia may (or may not) have been aggravated by the war in the Ukraine.  Yet, the short-fall was entirely predictable, over a decade ago, and  it will not go away when the war ends.

In anticipation, back in 2012, I called for a 'root and branch' reappraisal of the combined impact of the Renewable Energy Target scheme, in the context of the operations of the National Electricity Market (NEM):

 

2012

"The present government interventions in electricity markets, intended to move the industry from coal to renewable energy sources, are responsible for most of the rapidly rising cost of electricity in Australia.  These interventions have introduced unanticipated distortions and inefficiencies in the way that electricity is delivered.

Industry experts point to looming problems in supply and even higher price increases.

A 'root and branch' review of these mechanisms is urgently required to prevent ever increasing prices and to prevent further potentially crippling distortions."

I asserted that together these were making essential base load generators unprofitable and may lead to brownouts and blackouts in the future:

2012

"Now, in addition, rooftop photo-voltaic (PV) solar is beginning to add power to local distribution grids in mid-summer, when the market price is at its maximum and thermal stations have previously been assured of a profit.  Again the retailer pays for STC’s that subsidise the price of solar.

While again we might applaud the lowering of the peak market price and the reduction of peak grid currents at this time, we will not be so pleased if failure to invest in new generation capacity results in even higher prices; and future brownouts and blackouts.

While at first sight there appears to be a well established competitive generation market, the renewable energy targets and the associated certificates (paid for by our retailer and appearing in our bill) may be having an increasingly adverse effect on future investment decisions; with potentially disastrous outcomes ‘down the track’."

The article was written at a time when an ill-conceived Carbon Tax, that only targeted particular industries and in some cases individual businesses, was severely distorting the energy marketplace even further. 

A year earlier I had objected to the Gillard Government's short lived Carbon Tax on these grounds:

2011

"Well, the Gillard government has done it; they have announced the long awaited price on carbon...

Accusations of lying and broken promises aside, the problem of using a tax rather than the earlier proposed cap-and-trade mechanism is devising a means by which the revenue raised will be returned to stimulate investment in new non-carbon based energy.

Taxation always boils down to 'robbing Peter to pay Paul'. In this case the Government knows who Peter is but they apparently have no idea, or too many, about Paul.

It is the very definition of administrative inefficiency to rob Peter to pay Peter. Thus any tax that requires offsetting payments to those taxed is poorly designed; administratively cumbersome and likely to be extremely inefficient; a bad tax."

The Carbon Tax has gone but not the underlying problem remains: traditional coal fired power stations - upon which we will still need to rely for at least another decade - cannot remain viable as long as they are continually gazumped in the NEM by cross- subsidised renewable electricity generators.

This cross-subsidy, is in the form of Large-scale Generation Certificates (LGC's), paid for by electricity retailers (in other words: you). Each MWh of renewable energy supplied receives this cross-subsidy (effectively at the expense of other generators). It applies irrespective of the rapidly fluctuating (NEM) market price for that electricity (energy), that from time-to-time is very low or negative, due to ample wind or sunlight and low consumer demand.

By this means, renewable electricity, including rooftop solar, has been given a 'leg-up', in order to meet the Australian Government's Renewable Energy Targets.

When governments intervene in markets it always has consequences. Such an intervention maybe necessary in the long-term public interest, for example due to externalities, like the environment, or international responsibilities. Yet, then it is beholden on Government to put in place accompanying means of mitigating the inevitable negative consequences. 

In this case the negative consequences of Renewable Energy Targets on base-load electricity generation have been well known for well over a decade but nothing has been done in mitigation.

Possible mitigations might include:

  • an off-market base-load generation reservation and/or, perhaps;
  • ineligibility of all Renewable Energy Certificates (small and large scale) for energy supplied when supply exceeds demand.

Comprehensive modelling of these and other possible interventions, such as a targeted subsidy, is now essential to determine the best transition path to a secure electricity future.

A 'root and branch' review is long over-due.

If only...

'If onlys' are a bit pointless, yet I'll say it again: Had we embarked on building just three nuclear power-stations similar to the Cruas Nuclear Power Station in France, two or three decades ago (read more...), we could already be 'clean and green' and not in the predicament we now find ourselves in today. 

Instead, we find ourselves paying for Snowy 2.0 that will be: more expensive; more environmentally damaging; and totally inadequate to make a significant difference (see: Pumped-Storage Hydropower (PSH). Read more....

But that's all water over the dam now.

Travel

The Greatest Dining Experience Ever in Bangkok

A short story

 

The Bangkok Sky-train, that repetition of great, grey megaliths of ferroconcrete looms above us.   

All along the main roads, under the overhead railway above, small igloo tents and market stalls provide a carnival atmosphere to Bangkok.  It’s like a giant school fete - except that people are getting killed – half a dozen shot and a couple of grenades lobbed-in to date.

Periodically, as we pass along the pedestrian thronged roads, closed to all but involved vehicles, we encounter flattop trucks mounted with huge video screens or deafening loud speakers.

The Secret

 

 

 

Lansing Michigan was a fine place to grow up, she guessed.  It was nice; and safe.

Her dad worked in the Michigan State Government and her mum stayed home. They weren’t rich but they were comfortable. Their new house was big, the nicest they had lived in and it was in a really good area. 

She had never been overseas, unless you count nearby Canada, and that was mainly on trips to Niagara Falls, usually when one of Mum’s sisters came to stay. When they passed through Sarnia, into Canada, Dad would always say "Yea! Overseas again!". It was about his only joke.

Sometimes they went through Detroit. But after what had happened there the last time, she shut that out of her consciousness. No wonder she is timid and takes fright easily. Now if a friend even seemed to be driving in that direction she would go into the foetal position and shut-down.

It appears that Assange's theories about petite and grand conspiracies are well founded; and illustrated by his own case.
