A few corrections
- 30 % of power you are importing tonight is actually RE (assuming no dilution from Tas, which there is)
You're talking about routing power nearly 2,000km from Tasmania and Snowy Hydro to South Australia for the sake of an imaginary carbon monster - not only is that really inefficient losing several percent on the way but its vulnerable to storm events and solar flare. Even things like hot sunshine can expand the lines and cause them to lose more power.
It's really stupid from a technical standpoint to be so reliant on a grid where power traverses such huge distances.
- Less than 11% of SA's power requirement last year was imported. However SA exported 6%, so your "half", is actually 5% and last year was unusal in that previous years prior SA was a net exporter. - 33% of Victoria's total electricty generation is RE
The usual strategy the renewable energy advocates use to muddy the water is to make grand claims about the rated capacity of renewable energy projects COMBINED and then act as if they do that output all the time. As they've discovered in the UK the total output of a wind farm is usually just a fraction of its rated capacity - in fact some have been consistently producing less than ten percent of what they're rated at - in which case they're so unreliable and have such meaningless output that they might as well have not been built.
We are talking about what happens at night and in times of 'wind and solar drought', which is when the national grid will be under the most stress particularly early evening. We're 'lucky' today here in South Australia, a cool change has broken the wind drought experienced over the last three days and wind has decided to show up for work today - however it's overcast so the solar farms are having their turn to call in sick.
You also continually make misleading claims about things like the SA Tesla battery - it cannot (and is not designed to) replace grid power because it can only run at maximum output for less than an hour.
Renewables almost never - NEVER - get to generate what their plated capacity is so please don't quote those figures, they're meaningless.
- The project Snowy and that Snowy 2.0 project you heavily critise will replace the Latrobe valley.
Snowy 2.0 cannot possibly replace reliable coal-fired power plants like Loy Yang - for reasons that I've already cited on this board.The Conversation.
Again, you're confusing rated output with how much they're actually going to produce. Snowy 2.0 needs energy put into it in order to have an output, it's not a power station. What happens during a wind drought when the 'battery' can't be charged?
You people live in a fantasy world that just isn't real.
