There is enough actual data and evidence to suggest the above is aspirational but not achievable with anything proposed in today's renewable technology. The article this thread is based on has numbers which don't stack up. People link to the article but can't explain how you pump water up a hill if there is no electricity. Sure ignore the problem, it won't go away and when we have rolling brown-outs and higher electricity prices we can all blame the politicians.
Also, this is from the speakers notes from the May AGL presentation - ann-presentation-to-macquarie-australia-conference-2017
------
"You can't satisfy more demand without time shifting renewable energy into other parts of the
day .......When the sun doesn't shine and the wind doesn't blow you need to move your energy around.
So, the answer can only be storage."
"One way of estimating this is using the model we just discussed of moving energy.
That is, if 65 per cent of renewable energy generated has to be time shifted intra-day to match
demand, then you roughly need to build 350 gigawatt hours of storage. In physical terms, with today’s technology, if that storage was provided by batteries, this would fill some 350,000 44-foot storage containers, which if laid end to end would stretch from Sydney to Perth with plenty to spare.
The devil as always is in the detail."

If each container has a 1kw air conditioner we need 350MW per hour extra electricity, add the round trip battery losses and then consider the 10 year life, need for replacement and the solutions proposed don't look so green to me.
