Grattan weighs in on renewables

Tony Wood from the Grattan Institute is one of those lucky people who seems to know everything, and repeatedly sets us all to rights. So when he spoke about the Institute’s new report Keeping the lights on: lessons from South Australia‚Äôs power shock (Press Release, where you can download the report) my BS detectors were fully operational. On further investigation, however, the report has value, but there is a twist.

In brief, he points out that we have no climate policy that will reduce emissions in our power system beyond the RET to 2020, and that we need climate change and energy policies that combine to produce reliable, affordable and sustainable clean power.

Keeping the lights on: Josh Frydenberg wants more gas

wind-solar.img_assist_custom-558x372_220Continuity of electricity supply is no trivial matter. Back in April-May 1996 at our place we had rain on 14 consecutive days.

Imagine not just the lights out, but rotting food in the refrigerator, no pumping of petrol at the bowser, the refrigerators and lights failing at the supermarket, no water coming out the tap. For the whole Brisbane area.

Now with interconnected grids through the National Electricity Market (NEM) established in 1998 South Australia withstood a lesser challenge recently albeit with a huge spike in electricity spot prices, arguably prompting a showdown on where we are going with renewable energy and fossil fuels in this country.

NSW coal generation under pressure

Well it is if the country stays on its present policy trajectory.

Sophie Vorrath at RenewEconomy comments on the latest pitt&sherry electricity emissions update (April data). Back in 1998 coal used to supply 90% of NSW’s National Electricity Market (NEM) electricity. Now this has fallen to less than 75%. One factor is that demand is falling more in NSW than in other states, as shown in these graphs:
