Ever since Kennett privatised the lot, successive Victorian Premiers seem to have believed that they had no obligation to ensure adequate power supplies available to meet the inevitable growing demand.
It's a combination of privatised power gouging a captive market and the complete mess that 'green' energy sources have been making of the grid and the concept of reliable supply.
I think Brenton has every right to be furious - I felt exactly the same way after the blackout we had here in 2016 that was exclusively due to overloaded wind farms
although they did everything they could to try and bury that cause. Now the poor long-suffering grid captive South Australian residents such as myself have to pay $1,600,000,000 to build yet another transmission line to NSW in order to try and shore up our capacity during times that our rubbish wind-towers and solar inputs can't meet demand or are knocked out of action and so we don't need the $300,000,000 worth of diesel generators that Weatherill bought to back-up the grid any more.
NONE of this would have happened if South Australia's only coal-fired power plant - Playford at Port Augusta - was still supplying us with cheap and reliable power. Honestly, who on earth would want to be running a business in South Australia OR Victoria - we have between us the highest domestic electricity charges in the world and we can't even manage to keep the lights on all the time.
