Hume says, overturning the ban is for “lowering emissions and energy prices”. This is incorrect. CSIRO Gencost, on both large scale nuclear and SMR (on SMR, GE costs for Canadian SMR validate Gencost) shows that nuclear build time and cost means that >emissions while we wait and >costs on arrival.

…A lot of people wanted low energy costs and (quite a few of us) to do something about climate change. Solar was it and now we are installing batteries like we want a tomorrow.

Australia has seen solar as a good thing. Has taken a national approach to standards = cost reduction. Installers stuck around through the FUD of “the system can’t handle all of this VRE”. System operators were put back in their box when they claimed same…

According to the report it is not “several” times cheaper, it is *7* times cheaper. The report either can’t be right or the US is in “failed State” territory. Australian figures are correct. I would check those US figures. I think you will find they are stupidly high but not that high.

Renewables are expensive, initially. When I put panels on my roof the first kWh cost me just less than USD$4000, but to date the cost of each kWh produced has been USD$0.06. On the warranted path the eventual cost of each kwh will have been USD$0.03. Cheap.

Those of us that chose not to have children and do the other things because we were clear eyed about this wondering who these people are we live amongst who have had children and seem disinterested in their future welfare. I have been told having children was meant to make you less selfish.

On the plus side coal tar has been used for a long time to make hydrophobic dyes which would be useful to bring back colour to bleached coral. I have fond memories of otherwise lifeless coral skeletons kitsch coloured as keepsakes in Queensland tourist shops.

I will read with interest. BUT, can personally attest that electrifying everything drops “energy” bills by a very large amount. Getting petrol / diesel out of your life is a step change for savings. My original 2007 EV has had tyres and one wheel bearing replaced. My second 2021 EV, just tyres.

… Electrification of everything is in the same vein. Energy services used to be a major cost for my household. Removing all fuel and gas has made energy services an insignificant cost now. Massive drop in emissions too.

Ah, whoops. It would be good to see the spruikers’ response to round out the view given this is a 150 year asset. At $2B this would have been a good deal as not too much capital was tied up in it. Point should be taken by decision makers that the multi-technology mix for NBN …

… grid discharge really is a VPP thing unless pricing is very dynamic. They could of course do this and battery software control could handle it, but they would have to reward for capacity not just energy over here. I think we have a decent balance. Aside from Amber, TOU in the NEM is no good.

Yes there is but outside of a VPP (which value is questionable) the best price you can get is 10c/kWh feeding into, effectively, the peak period (when they sell for 53c). With the FiT (before peak) being 2c, they are encouraging self storage of own solar or grid charging and not grid discharge…

We gave up a lot of potential power for a lot more energy. Strategic use of that energy will now be key to making sure the investment enables the renewables transition.

There is a chance that someone will just build another one somewhere else which is not the same as a certainty of building it here. Perhaps Murray doubts the certainty part?

Only thing missing from the tariff is the opportunity to avoid the capacity charge (capacity market here). Not trying to avoid paying my share but never taking during the peak does save the community the highest costs of generation. Grid costs are somewhat factored into the tariff.

Cheap is high renewables low grid congestion and expensive is high fossil and a congested grid.
Just plug the tariffs into the battery and BEV and all charging is done during the 8c period.

Unfortunately I am in the West. What we have here is a neat time of use tariff where:
- 6 hours a day it costs 8c /kwh
- 7 hours a day it costs 19c /kwh
- 5 hours a day it costs 23c /kwh
- 6 hours a day it costs 53c /kwh

I am not sure I understand the point. If you have a battery and time of use tariff then the incentive is to charge when the grid has surplus cheap renewables (increasing min operational demand and market prices) and to remove demand from the grid when prices are high …
