Rough out a fossil fuel free system for a given populated area to replace a 1 GW coal power station, at 2020-2022 prices. use 1 year of hour by hour weather observations

Rules

maximum of 1 month per year scheduled downtime

1 hour per year unscheduled dark due to lack of storage.

No extension leads.

No hydro using naturally occurring sites for both basins (they're already in use)

30 year design life.


I'm selecting a local power station, now gone, in Anglesea Victoria. It has fairly good windpower prospects, including offshore. I'm using the weather observations from a town just along the coast called Airey's Inlet, or Hairy Singlet.

Well I failed at the first post, weather records at hourly intervals are not freely available. I'll do it day by day instead. I did find which at least recognises that wind/solar/battery is not credible by itself.

And rather amusingly here we are at mid day the start of autumn, and this is the the 100% renewable grid on an island between here and tasmania

But I think it is broken since none of the numbers have changed in 2 hours (I've contacted them)

Here's the eastern seaboard of Australia, a consistent source of embarrassment

Thinking about the absence of hourly data - given that a renewable system must have days worth of storage that is not really a problem.

Nice. That quality of data is available for Oz, but anything more than the three most recent days is paywalled.

Paywalled? For what should be public info? Sounds like Putin involved?

Yeah it's disgusting. BoM does the same with weather data. While I agree there is a cost in hosting/serving big lumps of data, text files are probably the tiniest component of data around.

can you make a script to visit the site each day, and extract the info (print screen ?), and build you own history ?

another day in paradise, or is paradise one day closer ?
 
Yes, but of course that'll take a year! I think I'll take Pud's brilliant data and play with that instead. Just put control knobs on each generation source, and the difference between what was used and what is generated comes from batteries, plus some more to charge the batteries. I see the UK are just signing off on some mini reactors.

Rolls Royce make the reactors for the nuclear subs. Shouldn't be too difficult to convert the design to terrestrial use. Gubberment have put some cash in as well.

Greg: read the caveats on each dial. Wind power is not all monitored.

Oh, and it's certainly not MY brilliant idea! Check the source. They msy be co-operative?

"Rolls Royce make the reactors for the nuclear subs. Shouldn't be too difficult to convert the design to terrestrial use." ... like the Russians do ?

I gather from the lack of solutions that the voluble commentators in this forum are not able to do this. No surprise there.

Grins, well that's certainly a possibility, but I prefer my version. The reason I'm pretty confident that the results would be too scary is because I've seen that isolated grids rely on FF backup, or connection to far away grids that are FF. It would be interesting to see counterexamples.

Therefore not entitled/qualified to discuss it?
