How many times have we seen this already. The Greens sell the public on getting 'free' clean electricity. A project is approved by a vote buying politician with a cost estimate low enough to get Cabinet approval.
The estimates conveniently don't include the cost of additional electricity distribution infrastructure such as additional transmission lines, not the cost of various back-up facilities including generators and batteries.
The real end cost comes in 1000% above the original estimate, but nobody gets sacked.
A case in point is the Snowy Mountains Hydro 2.0 project. The plan is to use excess wind and solar power to pump water from storage lakes up the snowy mountains to run back down the mountain producing hydro electricity when solar and wind isn't available.
The scheme, first costed by the Turnbull Administration as a $2 billion project. It is designed to expand the existing Snowy Mountains Hydro-Electric Scheme by adding an additional 2,000 MW of energy storage capacity.
The government is only admitting a new cost estimate of $5.8 billion not including transmission. https://reneweconomy.com.au/not-happy-bowen-says-snowy-2-0-is-problematic-but-wont-be-canned/
At that cost the Government is not prepared to walk away. But that only covers the pump, storage and generation. Wait till the public understand it is now estimated to need up to $20 billion from taxpayers, including transmission upgrades, to be completed this decade. Ten times the original estimate. https://www.news.com.au/finance/work/at-work/supermax-prisoners-are-served-better-food-union-erupts-over-workers-abysmal-conditions-at-snowy-20-site/news-story/b8ccf3d69b6443b026c2bbfcc7962d53
It's amazing that to make renewable energy reliable, it is necessary to produce much more electricity than is utilised by the end users to provide many back-up options. Does anyone calculate the total CO2 emissions required to produce the excess power, storage and backup?
