1. South Australia wants an apology from the PM

On September 28 we had the first anniversary of the dirty big storm the brought down the power pylons in South Australia causing a state-wide blackout, as the Heywood interconnector exceeded capacity and tripped.

Now the state want an apology from the PM. Energy minister Tom Koutsantonis: Continue reading Climate clippings 116

Climate clippings 115: beyond coal

1. Liddell to go

The die was cast at the AGL annual general meeting. Liddell will be closed and not sold.

    Mr Vesey spent the bulk of his address explaining how AGL would replace the capacity lost at Liddell, including new wind and solar farms, up to 750 megawatts of new gas-fired plants and a 100-megawatt upgrade to the more modern and larger Bayswater coal plant nearby. A 250 MW battery at Liddell and demand response will also come into play, he said.

A tsunami of renewables

The AFR reports that Josh Frydenberg and Labor’s Mark Butler had a bit of a love-in when they shared a platform late last month. Ben Potter said they were peas in an energy pod.

    Frydenberg waxed lyrical about the shrinking cost of solar photovoltaic – from $1.6 per kilowatt installed in 2014 to 19 cents per kilowatt last year. Battery storage has also halved in cost and added half as much capacity again in just five years, he enthused, and “demand response” – where customers curtail their usage or offer their batteries and smart appliances to the grid during demand spikes to avert blackouts – has an “incredibly” important role.

    Butler took his cue, noting that the system is undergoing a “massive, profound and irresistible transition which will just continue whether we like it or not”.

Butler said that if anyone could get the Clean Energy Target (CET) through the LNP party room it would be Josh. Continue reading A tsunami of renewables

Solutions to the energy crisis

Malcolm Turnbull has now, for reasons best known to himself, elevated “energy crisis” to a “national security” issue. Ben Potter puts the situation well:

    A decade of fighting over renewable energy, carbon prices and fossil fuels has left Australia with some of the world’s dirtiest and costliest energy – a bitter yield from historical abundance.

    Three years ago, manufacturers began complaining they couldn’t get gas, and 18 months ago the South Australian grid started to wobble.

    Now, electricity and gas prices across the eastern states are two to three times their levels only a couple of years ago.

    Gas exporters overcommitted to foreign buyers; the federal government mismanaged renewable energy and the regulatory apparatus – and politicians responsible for it – are frozen in the headlights.
