20 September 2017, The Conversation, Vietnam’s typhoon disaster highlights the plight of its poorest people. Six people lost their lives when Typhoon Doksuri smashed into central Vietnam on September 16, the most powerful storm in a decade to hit the country. Although widespread evacuations prevented a higher death toll, the impact on the region’s most vulnerable people will be extensive and lasting. Government sources report that more than 193,000 properties have been damaged, including 11,000 that were flooded. The storm also caused widespread damage to farmland, roads, and water and electricity infrastructure. Quang Binh and Ha Tinh provinces bore the brunt of the damage. Central Vietnam is often in the path of tropical storms and depressions that form in the East Sea, which can intensify to form tropical cyclones known as typhoons (the Pacific equivalent of an Atlantic hurricane). Typhoon Doksuri developed and tracked exactly as forecast, meaning that evacuations were relatively effective in saving lives. What’s more, the storm moved quickly over the affected area, delivering only 200-300 mm of rainfall and sparing the region the severe flooding now being experienced in Thailand. Doksuri is just one of a spate of severe tropical cyclones that have formed in recent weeks, in both the Pacific and Atlantic regions. Hurricanes Harvey, Irma and, most recently, Maria have attracted global media coverage, much of it focused on rarely considered angles such as urban planning, poverty, poor development, politics, the media coverage of disasters – as well as the perennial question of climate change. Disasters are finally being talked about as part of a discourse of systemic oppression – and this is a great step forward. Read More here

15 September 2017, Renew Economy, Blackouts and baseload: Debunking myths of AEMO reports and Liddell. The day after the release of the two key reports from the Australian Energy Market Operator last week – its annual Electricity Statement of Opportunities and the specially commissioned report on dispatchable generation requested by the federal government – RenewEconomy could barely believe what it read and heard in the media. Consumers were being frightened into thinking that the lights were going out, the economy would collapse, and they’d all be better off going out to buy a generator and a supply of candles and batteries. The only possible solution to the crisis, we were told, was to stop renewable energy and keep the Liddell coal generator on line. What was missed – in the fog of politics, ideologies and deliberate misinformation – were the fundamental messages of the two reports: that the energy system is transitioning quickly, and it is more or less unstoppable, because of the march of technologies and global trends. This is not a bad thing, AEMO boss Audrey Zibelman underlined. But it does require some policy certainty and some co-ordination to ensure that Australia’s dirty, expensive and increasingly unreliable grid can be transformed into a smarter, cleaner, more reliable and cheaper source of power.

13 September 2017, The Conversation, More coal doesn’t equal more peak power. The proposed closure date for Liddell, AGL’s ancient and unreliable coal power station, is five years and probably two elections away. While AGL has asked for 90 days to come up with a plan to deliver equivalent power into the market, state and local governments, businesses and households will continue to drive the energy revolution. At the same time as AGL is insisting they won’t sell Liddell or extend its working life, government debate has returned to the Clean Energy Targetproposed by the Finkel Review. Now Prime Minister Malcolm Turnbull is suggesting a redesign of the proposal, potentially paving the way for subsidies to low-emission, high-efficiency coal power stations. But even if subsidies for coal are built into a new “reliable energy target”, there’s no sign that the market has any appetite for building new coal. For a potential investor in a coal-fired generator, the eight years before it could produce a cash flow is a long time in a rapidly changing world. And the 30 years needed to turn a profit is a very long time indeed. We also need to remember that baseload coal power stations are not much help in coping with peak demand – the issue that will determine whether people in elevators are trapped by a sudden blackout, per Barnaby Joyce. It was interesting that a Melbourne Energy Institute studyof global pumped hydro storage mentioned that electricity grids with a lot of nuclear or coal baseload generation have used pumped storage capacity for decades: it’s needed to supply peak demand.

12 September 2017, Renew Economy,AEMO: Our advice was pretty straight forward, we need dispatchability. As the federal Coalition continues to push the case for an ageing, unreliable, and slow moving coal generator to maintain energy security in the 2020s, the Australian Energy Market Operator has underlined its advice to the government last week: it wasn’t a push for more baseload. “We need flexible capacity that can be switched on and off, and we need to transition to a new generation of Australia’s principal energy market institutions, and the newly-formed Energy Security Board. “Our advice was fairly pragmatic,” Zibelman said. “We are concerned that on a 45°C day if we lose a generator (which AEMO has said is quite likely) we want reserves in the system to be able to respond. “In our report we identified the fact that with amount of variability (from solar and wind energy and electricity usage) is changing rapidly, we need resources that can change rapidly. “That may be different to traditional baseload resources, which do not move a lot. It doesn’t mean baseload is bad, it’s just that we need a different portfolio. (Baseload) may not be able respond in the time period we need it to respond.” Sound like Liddell? Not really. The plant owner AGL Energy has made it clear that Liddell is old, increasingly unreliable, expensive to maintain, prone to unexpected outages and can’t be relied upon at times of peak demand, particularly as temperatures rise. Zibelman’s comments, like the two AEMO reports it released last week, contrast starkly with the Coalition government’s contention that AEMO had insisted that rapid action was needed, and that that rapid action must mean that Liddell’s life span must be extended. Zibelman made it absolutely clear that her preference was for fast, flexible technologies, both in supply and demand, and bother in front and behind the meter. Importantly, it had to be technology that the market operator could rely upon. Read More here
