BBC reports this complex news from the British Antarctic Survey. There had been reports years ago re snow increasing down there but surveys were not as comprehensive as this.

German raider Komet passage north Siberia 1940
Reading my attention grabbing new book “Storm of War” I got reminded of this historic voyage of the Komet (aka Raider B of the British Admiralty) from August 1940 which was with the help of Soviet icebreakers. It is noteworthy that despite decades of global warming and technology advances the northern passages are still little used except by ice breakers and the oil industry. The Komet created mayhem in the SW Pacific sinking several ships including (with Raider A the Orion) the liner Rangitane in early hours 27Nov1940 off NZ East Cape. The Komet also voyaged to the Antarctic – not sure what exactly they were looking for. Vic.University German Raiders in the Pacific. I am building a timeline of raiders engagements in the SW Pacific – so far I have tackled 1940 – still to find time to assemble 1941 info.
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.
