7 October 2016, Renew Economy, Finkel to lead NEM review, but states hold to renewable targets. Federal and state governments have agreed to an independent inquiry into the rules governing Australia’s energy markets, but the states have resisted attempts by the Coalition to force them to back away from their individual renewable energy targets. The hastily called meeting, held in Melbourne after the Coalition decided to use the South Australia blackout to attack state-based renewable energy initiatives, broke up with no agreement about individual renewable energy targets. But they did agree to an independent review that the federal government says will provide a “blueprint” for Australia’s power security to be led by chief scientist Dr Alan Finkel. There will be two other members, although they have not been named. States expressed hope that the Finkel report would move towards a more integrated response and market framework. Finkel, a keen supporter of nuclear, has also expressed his interest in solar and storage. “My vision is for a country, society, a world where we don’t use any coal, oil, natural gas; because we have zero emissions electricity in huge abundance and we use that for transport, for heating and all the things we ordinarily use electricity for,” he said during a media event relating to his appointment. “With enough storage, we could do it in this country with solar and wind,” Finkel said at the time. The appointment of Finkel was pushed by South Australia. It was supported by other states, but they insisted for other members on the panel who had experience of energy transitions. Read More here

5 October 2016, The Conversation, Lessons from South Australia’s blackout: we need to make infrastructure more resilient to climate change. Last week’s storm and subsequent state-wide blackout in South Australia reminds us how important the electricity grid – and other infrastructure – is for our communities. Immediate analysis suggests the blackout was caused by the collapse of transmission infrastructure in South Australia. Australian electricity networks, like most transmission networks worldwide, rely on above-ground conducting wires held aloft by large towers. Some of these towers were blown over in the South Australian event. While the storm hasn’t yet been specifically linked to climate change, it also serves as a reminder of the increasing challenges of delivering essential services in a more variable climate and slowing economy. Power, water, transport, health, defence and communications infrastructure can be exposed to climate variability and change simply because of their long lifetimes. Therefore, many if not most owners and operators of essential infrastructure have commissioned climate vulnerability and adaptation studies. There are many good examples of adaptation. For instance, Queensland Urban Utilities, the major water distributor and retailer in south-east Queensland, is implementing a large program to make the water and wastewater delivery network more resilient to flooding. But there is increasing recognition among climate adaptation researchers that many of the recommendations from climate adaptation studies aren’t being adopted. This is sometimes referred to as the “plan and forget” approach to climate adaptation and it leaves critical infrastructure vulnerable to weather extremes. Read More here
5 October 2016, The Guardian, SA blackout due to ‘transmission system faults’ in extreme weather, report finds. Energy economist says preliminary report makes clear South Australian event was ‘a transmission failure, not a generation failure’. The Australian Energy Market Operator has pointed to South Australia’s extreme weather last week as the prime cause of “multiple transmission system faults”resulting in a statewide blackout. In a preliminary report the regulator cites severe weather as the factor triggering the transmission system failures “including, in the space of 12 seconds, the loss of three major 275kV transmission lines north of Adelaide.” In addition to the transmission lines, Aemo notes in the late afternoon, after “multiple faults in a short period”, 315mW of wind generation disconnected, which affected the region north of Adelaide. It says that uncontrolled diminution in power generation “increased the flow on the main Victorian interconnector [Heywood] to make up the deficit, and resulted in the interconnector overloading”. The overload of the Heywood interconnector tripped the system, which caused the blackout. Read more here
5 October 2016. The Military and Climate Security Budgets Compared. Fifteen of the sixteen hottest years ever recorded have occurred during this new century, and the near-unanimous scientific consensus attributes the principal cause to human activity. The U.S. military’s latest National Security Strategy says that climate change is “an urgent and growing threat to our national security, contributing to increased natural disasters, refugee flows, and conflicts over basic resources like food and water.” What they don’t say is that the overall balance of U.S. security spending should be adjusted to fit that assessment. And we know less about how much we are spending on this urgent threat than we used to, since the federal government hasn’t produced a climate security budget since 2013. In this new report, Combat vs. Climate, the Institute for Policy Studies steps in to provide the most accurate climate change security budget currently available, drawing data from multiple agencies. And it looks at how these expenditures stack up within our overall security budget. Then, the report ties the military’s own assessment of its urgent threats to a budget that outlines a “whole of government” reapportionment that will put us on a path to averting climate catastrophe. This is our status quo: As global temperatures hit one record after another, the stalemate in Congress over funding to respond continues. Climate scientists warn that, as in Syria, unless the global greenhouse gas buildup is reversed, the U.S. could be at risk for conflicts over basic resources like food and water. Meanwhile, plans to spend $1 trillion to modernize our entire nuclear arsenal remain in place, and projected costs of the ineffective F-35 fighter jet program continue to climb past $1.4 trillion. Unless we get serious about moving the money, alarms from all over about the national security dangers of climate change will ring hollow. Access article here. Access report here.
