That's a difficult choice. A choice between new dirty expensive coal power that works all the time, and new expensive renewable power that works some of the time.
In the 'Aus' newspaper a week or so ago was an article about a guy who had installed a $30,000 battery ( AGL I think ) that cost him $5,000. Hmmmm I wonder who's paying the rest?
During the next SA blackout, If he thinks all the power in that battery is his to use, then I've got news for him, and it's all bad.
By the way, it was only a month or two old and was going to be replaced.
