The Tassie electricity debt between hydro and network is ~$2.4Bn for population of 515,000 so for a family of four paying say $2,880 annual power bill the share of debt is $18,640. A major industry for Tasmania is extracting more money out of the Commonwealth – a task made easier by the infestation with Tas Senators due to our constitution. With the birth of the Snowy 2.0 pumped hydro concept so fawned over by PM Turnbull Tassie Hydro people saw in a flash that – “hey we can do that too” and with a few months at the desktop they assembled the Battery of the Nation concept. This RenewEconomy article is far from thralled and if they put a ? on it – really must be bad. They put the cost at ~$9Bn similar to Snowy 2.0 but of course way less efficient being on the end of ~650km of risky and energy wasting cable. RenewEconomy says ARENA is supporting but their www page shows no sign yet of Battery of the Nation. AEMO NEM Dispatch Overview – NemWatch – OpenNEM – NEMlog

Dr Kerry Schott says no more coal fired power will be built in Australia
“No way” anyone will fund new coal plants under NEG, says Schott. It puzzles me what Dr Schott thinks will happen to prices and reliability if we allow deterioration and shutdowns of our existing coal fired fleet. Here are average AEMO prices for the last 12 months in order of greatest percentage of coal fired installed capacity.
Qld $74.29 – NSW $81.93 – Vic $95.04 – SA $100.92 – Tas $92.06
Victoria was close in price to Qld and NSW in 2013 to 2016 (at ~$50 or under) before the disruptions of Port Augusta and Hazelwood coal fired shutdowns. Is there a pathway to holding prices at current levels and having 365/24/7 reliable power if we progressively shut down the coal units?
Obviously wind is not reliable, best locations are used and NIMBY’s oppose new projects.

50MW Solar PV planned at Forbes NSW
This must be building on the stunning success of their Jemalong Solar Thermal project that has been gestating for at least three years. Chemical fire near Forbes burns into second day 14 June 2015

Or is ARENA closer to the truth to say “…concentrated solar thermal (CST) technology could be a commercially viable form of dispatchable renewable energy within a decade.”
Adelaide power price booms as interconnector fails
“At 1114 hrs(26Apr18) the South East Substation to Tailem Bend Substation No.1 275 kV Line and the South East Substation No.1 SVC tripped.” See AEMO Market Notice 62496. About 400MW was lost and lasted till about 1530 hrs, gas increased from 46% to 61%. Shown well on OpenNEM for SA. Put your specs on to see the mini-micro contribution of the famous battery. Notice they fired up some diesels too. The SA average price for the day zoomed to $405.20 but the 30min intervals went into several $thousands and 5min intervals over $10K. Interesting the prices surges in Tasmania on 24th and ANZAC Day – I see too BassLink is still broke, been out for 5 weeks. Ah “The Battery of The Nation!!” So much idiocy around our electricity policy.

ABC glorifies mediocre mini TESLA battery
After 4 months operation the ABC says – How Elon Musk’s big Tesla battery is changing Australia’s power landscape – Note!! South Australia still has the highest prices in the NEM. – The reality about the midget battery from the source report from Energy Synapse is rather different. Four months in, SA Tesla battery is showing mixed results in energy arbitrage – Other quotes from Energy Synapse in italics, mine bold. – Tesla battery is being heavily utilised – the Tesla battery consumed an average of 116 MWh per day for charging. In contrast, it delivered an average of 94 MWh per day back into the grid. …average efficiency of the battery has been 82%. against…spec sheet efficiency of 88% – Tesla battery made $1.4 million in the energy market, but is losing money 47% of the time – “$1.4mill is Chickenfeed!!” – the Tesla battery made 95% of its net revenue in just five (very volatile) days – “welcome to most of the boring year where profit will be difficult to graft” – on 57 days (47%) the Tesla battery actually lost money in the energy market – the operators of the battery will need to be careful to avoid needlessly cycling the battery for little financial gain – “buy low, sell high” is not as easy as it sounds.

The energy market is incredibly complex – Some food for thought as the race to build big batteries begins. As usual where renewables are concerned Australia is rushing in before engineering solutions are proven. And much of the above will apply to Snowy 2.0. AEMO has a report on the TESLA battery too but it only looks at FCAS. I would say in reply to AEMO – “our grid got by for decades before this wasteful toy battery”. For perspective – if the average NEM demand is ~32GW and the Hornsdale Big Battery is say 100MW then that is less than 0.3% of the NEM. Key links – AEMO Dashboard – NemWatch and Open Nem.
Monash Forum triggers Liddell lies & misinformation
It is positive for our electricity grid and power prices that a group of Govt MP’s has spoken the unspeakable and suggested building a new coal fired power station.
However that seems premature right now.
Closing Hazelwood has more than doubled the Vic AEMO wholesale price and has made Vic prices now the most expensive of the three big coal burning States. Comparing Jul-Dec2016 prices to Apr2017-Mar2018.
The elephant in the room right now is securing the normal operation and maintenance of Liddell past 2022.
The owners of Liddell are AGL who have only a nominal valuation on Liddell and clearly can not be relied upon to maintain it properly. The Govt could buy Liddell but it is a lame duck and if they needed to pass anything through the senate probably could not do that. Alinta and Delta are expressing interest in buying Liddell but AGL is saying it wants Liddell.
Around that issue the lies and misinformation need to be waded through and sorted.
One issue is I think there is zero chance AGL could replace the 1800MW of Liddell by 2022.
Something needs to be put in place soon to get Liddell off AGL because we will have a new Labor Govt by the end of 2019 the way polls are heading. Labor will not stop AGL shutting Liddell and the nation will be further harmed as prices will be pushed higher as they were when Hazelwood closed.
We were lucky last summer heat waves were moderate, few and usually on weekends so resulting price spikes were not severe. As we leave summer heat price spikes behind the Govt has the best chance to keep talking up gas supplies and talking down electricity prices but they seem so confused – for example thinking that massive spending on Snowy 2.0 will somehow lower prices.
ARENA says concentrated solar thermal not viable
The ABC and GreenLeft media ignoring this huge news – The Australian Renewable Energy Agency (ARENA) says concentrated solar thermal (CST) technology could be a commercially viable form of dispatchable renewable energy within a decade. English translation – not viable now. 
Which raises the question how do you generate renewable 24/7 dispatchable electricity? I thought there were already CS projects building near Port Augusta. I see that ARENA requested information from existing worldwide players – I bet they keep those responses secret.
I am reminded what Terry McCrann said –
“THE first and most important thing to understand about global warming true believers and the pushers of so-called “renewable energy” is that they lie. They lie effortlessly, seamlessly, continuously and without the slightest sense of shame. They lie deliberately and carelessly and casually, and even when they don’t realise they are lying. They lie without the slightest sense of self-awareness and with all the pomposity of stupidity aforethought.”
I have not got the slightest objection to CS Projects as long as zero taxpayer funds are risked. NSW is littered with small-scale failed CS projects. Cooma, Lake Cargelligo, Jemalong near Forbes. Here are pics and links re all three.
Electricity and gas prices booming in summer
My chart shows the damage caused to electricity wholesale prices by a few days of normal summer peak heat – which luckily were mainly on weekends and holidays.
I notice that Sydney gas prices right now at 9.5 are way over December at 7.4 and I trust the PM is speaking to gas company bosses. Vic gas market maybe never got the Turnbull phone call. I also notice that Vic coal generation is running at max ~4,400 to 4,600MW 24/7 these days. Machinery eventually breaks down. I see there were 50,000 homes blacked out across Vic yesterday and Vic Labor pollies are trying to say supply was not the problem. It seems obvious that with supply strained near the limit this would require more fiddle-faddling and jiggery pokery by grid authorities than if they had Hazelwood on line say and could have been ~1,500MW more relaxed about meeting the demand. They were assisted too by wind in SA picking up at peak demand time in Adelaide. AEMO electricity and NemWatch for a generation snapshot. Link to 5 charts of electricity price histories.
AEMO has a Grand Plan to further destroy our electricity grid
Shades of Baldrick. In a nutshell they propose arm waving swaths of renewable energy zones REZ’s. In Vic and NSW I counted 11 new hydro generation sites – do these require dams? Mad.
Even turning to geothermal – which has seen hundreds millions wasted $’s.
Imagine the NIMBY’s that will be stirred up by these dam proposals – stacks of wind farms near Sydney. Large map.
Mass sackings would help and appoint some Australian electrical engineers.
The Integrated System Plan Consultation pdf has some other interesting charts to be checked later.
Record daily wholesale electricity price for Victoria in Adelaide-Melbourne heat
The AEMO daily price for 18Jan18 for South Australia was $1,074 per MWhr which was the highest since $1,492.16 on 8Feb17 no surprise there. But Victoria yesterday recorded a stunning $905.22 which is 4.6 times the previous highest of $195.67 on 10Feb17. You can toggle between SA & Vic at this AEMO page and also choose between 30min and 5min price views. Then the NEM Dispatch Overview.
This record Vic price clearly reflects reduced generation post the closure of Hazelwood.
A couple of charts from the GridPublicKnowledge www pages for SA and Vic gives an idea what was happening yesterday with our stressed power grid. NemWatch gives a snapshot of generation sources.
and Vic
I also kept the SA screen for the 17th. Similar heat is forecast for Adelaide and Melbourne today but a late cool change is due which should be earliest in SA. I understand this heat is moving into NSW and Penrith has 40 forecast for today through to Monday. Will try and follow the effect of this on the NEM.
