20 years after that for the entire fleet to be replaced

Which is about the time the grid is projected to be mostly RE.

I am hopeful that charging infrastructure will mature to the point where significant charging occurs when vehicles are parked which is around midday and midnight.
I am not sure if V2G will be significant - there will need to be improvements in battery technology such that a significant increase in charging cycles will not affect battery longevity. Million mile batteries are on the horizon.

I wish the mainstream media would promote this stuff (NEM peaked in 2008, and renewables make up more than 25% of energy generation).

Quite a big achievement and tick for everything from LED downlights, to energy efficient stickers on appliances, to roof top solar initiatives like grants and generous fits. All policies that WORKED.

NEM peaked in 2008, and renewables make up more than 25% of energy generation

All good but the problem remains power prices. The goal should not be just % RE. Electricity reliability and affordability should be paramount - transition to RE should be subservient to that.

Electricity reliability and affordability should be paramount - transition to RE should be subservient to that.

A well-managed transition to RE should have benefits for reliability - after all, a single 1MW wind turbine tripping is a lot less of a problem than a single 300MW thermal unit tripping. Although generation tends to be a minor player in the reliability seen by end-users - transmission and distribution problems are a lot more common.

(And of course minimising greenhouse gas emissions is a critical goal as well).

A well-managed transition to RE should have benefits for reliability

And that's the point "well managed transition". The transition so far has not been well managed...

single 300MW thermal unit tripping

In the past such events have not been problematic due to excessive spare dispatchable capacity. These days a lot less resulting in numerous interventions by the market operator such as one recently in South Australia. AEMO has highlighted the current vulnerabilities of the grid - especially the lack of synchronous reserves.

 

[Vostok]

And that's the point "well managed transition". The transition so far has not been well managed...

Well prior to 2022 we had a Federal Government that fought tooth and nail against any meaningful transition. The LNP came up with 22 different energy policies in 9 years and failed to implement any of them.

The extent to which a transition did occur all happened due to the States and despite the Feds.

 

[Vostok]

I wish the mainstream media would promote this stuff (NEM peaked in 2008, and renewables make up more than 25% of energy generation).

Well, a lot more than 25% RE! 2023 YTD is 36%!

 

[Quickst]

a transition did occur

Transition yes but it remains a very poorly managed transition irrespective of political persuasion. It also appears that at least some of the transition depends on reducing demand - we remain a dig it up and ship it out rather than building a manufacturing value added economy which require energy to operate.

The stats for August. We are on the upward swing again with the depths of winter over.

For the first time, VIC has come second in the “diurnal hardness” stakes, just pipping SA on 0.78. Meaning nighttime renewable percentage was 0.78 times that of daytime - pretty good but low compared to what it is usually.

The relatively poor results in SA and VIC were compensated for by a big jump in renewable percentage in NSW and a smaller jump in QLD.

The stunning stats for September… a massive 41.5% renewable for the month - the third highest result ever (only beaten by 41.9% in Nov 2022 and 42.0% in Dec 2022) and a whopping 710 basis points higher than the result for September last year (34.4%). A YoY jump that big in December would mean Australia could get near being majority renewable powered for an entire month for the first time ever. I don’t expect to see that, but you never know.

We’ve also had an instantaneous renewable peak all-time record of 69.7% (oh so close to 70%!) which occurred only yesterday.

The stats for October. Apologies for the delay, there was a coding problem and some anomalous data that I had to remove (e.g. 30 hours where allegedly coal and gas generation went to zero in WA nope…)

Another record month, with national renewable percentage of 44.8% beating the previous record set in December 2022 by a whopping 280 basis points.

National daytime renewable percentage went over 50% for the first time ever.

All states recorded peak renewable generation over 65% - NSW even getting over 80% which is pretty extraordinary. SA nearly got to 80% renewable overnight!

What's the bottom cutoff wind speed for SNSWNB?

 

[Vostok]

Ok not so much a stat but a fascinating data point - now that 2023 is over and the final numbers are in, the NEM still hasn’t beaten the 2008 record for total electricity consumption. But it got very, very close. Like 22 GWh close, or 1 hour of consumption!

In 2008, total electricity consumption in the NEM footprint, including behind-the-meter rooftop solar, was 207.564 TWh.

In 2023, total electricity consumption in the NEM footprint, including rooftop solar, was 207.542 TWh. A tiny 0.5% increase on 2022, but an even tinier 0.01% below the 2008 record. You could argue that because 2008 was a leap year, and 2023 wasn’t, that is the sole reason the 2008 record still stands. 2024 should beat it… but I’ve been wrong before…

That’s incredible when you consider the population has grown 24% in that time. This is all due to increased energy efficiency across the entire economy - residential and businesses.

Taking out rooftop solar, total grid consumption continues to fall. In 2023 it was 184.406 TWh, 1.8% less than in 2022, and a whopping 11.1% less than the peak grid consumption in 2008. This is all due to rooftop solar displacing grid demand.

 

[Vostok]

What's the bottom cutoff wind speed for SNSWNB?

It’s not based on wind speed but total wind power generation. The cutoff is zero. If wind generates more than zero MWh in a 15 minute period, then the wind is blowing. Somewhere.

 

[Quickst]

This is all due to rooftop solar displacing grid demand

What about the removal of manufacturing capital from Australia. A lot of manufacturing was highly energy intensive. How much of that reduced grid demand?

bottom cutoff wind speed for SNSWNB?

I think an individual wind generator requires anywhere from 10-15kmh to start turning (to overcome inertia)

Additionally I've heard they need to be turned periodically if no wind for some reason
