Renewable Energy Discussion

[Cruiser Elite]

.... and it looks that this thread will be dominated by enthusiasts of the renewables...

Freedom of expression - what a bugger - come on non believers pick your games up

Another example that shows you know little about the nuclear industry. F irst you could have used this graph from Lazard which shows the unsubsidised cost of generation.

What you should note is the values in gold to the left of the graph. This represents the marginal cost of production in fully depreciated plants.

So why is nuclear so expensive in the USA? Because of regulation. Each nuclear plant must insure with a government mandated insure at a cost of $1 million a year. The fund has collected $4 billion and paid out $150 million.
But they also have to take out Secondary Financial protection at $20 million per year. That fund has taken in $14 billion and not a single pay out.
There are quite a few more regulatory costs.

Then turn to subsidies. This graph is for the USA and only has Federal subsidies. The States and local areas also have subsidies the large majority of which goes to renewables.

Yet this is how much is generated by each method of generation.

Hi drron,
You are almost alone here, and could be ridiculed here by enthusiasts of renewables.

They think that it is their thread.

It would be waste of time to argue with them here as the do not have much of operation, safety or risk of the network and power system.

Invite you to alternative thread:

"Support for nuclear power generation in Australia".

You are wrong on the "non believers".

High cost of power energy in Australia is killing new investment, businesses struggle with increasing power bills and domestic customers are not happy with their increasing power bills although support from governments.

And question is "Quo vadis"?

Looking back on the political enthusiasm for renewables in Germany, fact is that they closed their nuclear generation but now reopened their mothballed brown coal power stations ... It is embarrassing political strategy...

On resent COP28 many countries announced their strategy to include nuclear generation to meet their net zero emission commitments.

And here in Australia with the increasing cost and falling reliability of electricity option of nuclear power generation should be also on table for consideration by power generation experts and AEMO.

This is not a fight to abandon renewables but discussion on strategy to meet zero emission commitment.

Enthusiasts of renewables, activists and politicians should listen to experts and avoid emotions as costly mistake might be made.

Tagging people of a different opinion as "non believers" is indicating that you are rather biased person.

Only open minded people are able to see a big picture and include all possible solutions or options for consideration.

That is the reason that I am not willing to be involved in any offensive exchange.

There are a lot of scientists of different points of view and usually they to not tag opponents with term of "non-believers".

I also noticed that many activists started to pretend be a scientist, although they do not have deep knowledge from universities or science institutions...

I pointed out that what you described has never been the case. It's not anything new, inverters have had this function for a decade now

Your info on AS is correct.

However, these requirement were not promptly included in the Technical Code or Technical Rules of power utilities in the eastern seaboard and also in WA.
WA probably included the inverter over-voltage control function in the new connections about 2016. All earlier installed connections were without this control function.

My inverter produced in Brisbane and installed in 2007 in Perth don't have this function and may still function beyond 2030th. And there is a lot of similar installations in Australia.

Please be aware that in many remote areas distribution networks might be very weak prohibiting power exports. Also in many places saturation with already existing solar panels may prohibit power exporting from new connections.

My context - semirural.
the problem I have is that the street transformer (sits on a pole) and I am closest to the transformer. The street voltage is highest closest to the transformer and drops the further a house is from the transformer

During peak export my line V often hits 253V.
As the transformer is the old dumb transformer, it is not able to adjust output voltage on the fly without Ausgrid making manual adjustments - and it won't because the other houses might see a lower than acceptable voltage in the evening when the sun don't shine.

In many places, the electricity distributor is not allowing grid export due to the area not able to absorb grid export. The expectation is that rooftop solar will continue to grow, but what people seem to overlook or maybe they turn a blind eye is the capability of the grid at the street level may not be able to absorb all the grid export. Not only will FiT $$ be curtailed, but the amount that can be exported will also hit a limit.

Some will load shift using expensive batteries.
Many will just stop exporting.

So much for the overabundance. It's only an overabundance when the electricity can travel from where it is produced to where it is used.
It's no use to me that I am exporting 20MWh per year to my street when I will be drawing from the grid while parked in the carpark 30km away

After consideration the Moderation Team will not be reopening this thread or approving any other such threads.

From the Terms of Service:
“AFF is primarily a travel/aviation website. Political posts are therefore not permitted unless they relate directly to travel or aviation. Furthermore, any such post needs to be factual with no subjective commentary.”

It is very clear that this and similar threads very quickly degenerate into multiple posts in breach of the above.
