$624,000,000,000 ($624 billion) bill for Blackout Bowen’s Big Batteries for just 3 windless winter nights. Given the ABC will never even try to inform the public, and with Blackout (being mathematical challenged) and incapable of making the calculations - let’s do the sums on how much it would cost for Big Batteries for just 3 windless winter nights if we do away with fossil fuels and try and run the economy on Chinese made solar panels & wind turbines to reach Net Zero. How much power is needed As the graph below shows, we are going to need an average of around 20,000 MW of battery power to replace coal/gas when solar power goes to sleep, from around 4pm on a winter’s afternoon to around 8am the following morning. That’s 16 hours x 20,000MW = 320,000 MWh And doesn’t take in account the huge increases in power that will be needed to charge millions of electric car and trucks overnight under Net Zero - or the extra electricity needed if gas heating is banned. The cost of the batteries Renew Economy estimate the cost of NSW’s ‘Giant Waratah Super Battery’ at $1.4 billion for 1680 MWh. That’s $833,000 per MWh But let’s be generously and discount that to $650,000 per MWh. So the cost for one night’s battery storage (ignoring the additional costs input-out losses) is; 320,000 MWh x $650,000 = $208,000,000,000 That’s $208 billion. Total cost over just 3 nights But just one night’s storage is totally inadequate, because you only have an 8 hour window during winter (8am to 4pm) to recharge the batteries with "excess power" ready for the next night. Therefore, at an absolute minimum you’d need 3 nights battery storage (and even this likely to be dangerously inadequate) So for just 3 nights the cost is $208 billion x 3 = $624 billion. That’s $624,000,000,000 for the batteries alone. That’s around $23,000 for every man women and child in the country - or $92,000 for a family of four. Expected life span And grid scale batteries only have an expected life span of 10 to 15 year, then you have the costs of burying them deep in some giant land fill due to their toxicity, and then you have to start again. linkedin.com/pulse/elaborati…. Other costs And that $624 billion doesn’t including the cost of the mass inefficient overbuild of solar/wind so you might have a chance of having some excess power between 8am to 4pm (if you get a sunny day with consistent wind). And then there is the additional costs of all additional transmission lines need. It would bankrupt the nation Its a complete farce, an economically impossibility, that would bankrupt the nation. But that’s the fairytale that Blackout Bowen and Matt Green are trying to sell to the Australian public. We need new coal We’d get a new coal fired power station for less 1% of the cost of Bowen & Kean’s Big Battery plan. esfccompany.com/en/articles/… And I’d welcome the opportunity to debate Labor’s newly appointed Climate Commissar Matt Kean on the above - but zealots like Bowen & Kean don’t deal in facts, science or economics.
