In the article the batteries max power output is 30 MW

It represents less than 10% of the max power output of the plant (380 MW)

When I read "The battery section will provide four hours of storage capacity at full discharge" I understand that it will provide 4h x 30MW = 120 MWh of energy. Do you understand it as 4h x 380 MW = 1520 MWh of energy ?

[EDIT] From other source [1] it seems my interpretation is the correct one: "The onsite battery storage facility will be capable of providing 30MW of continuous power for four hours."

That completely changes the narrative: the total energy the battery storage can deliver by itself is less than what the solar + wind provides at full power in half an hour. Also, this amount of energy will be delivered at a peak power of less than 10% than the peak power of Solar + Wind

The first article is an example of what I am talking about, I linked to the second one to make it clear they don’t currently release battery power at night.

Anyway, I think it’s reasonable to think in terms of “50 MW of PV solar and 30 MW * 4h of battery storage” + a wind farm because they normally charge batteries from solar via DC to avoid DC>AC>DC losses. But it might be a true hybrid system.

If you edited your comment (I did not see first article mentioned), please show it with some kind of flag. Otherwise it can make the thread confusing

If there was as supraconducting pipeline for current, could a solar receiving part of the planet, send power to a part that is already in shade?

Probably not. Super conductors don't really solve any problem because they loose their super conductivity at high B fields; i.e. when they transport large currents. Case in point the highest field magnets are not made w/ superconductors but water cooled copper pipes.

So you'd have to transform the electricity to high voltage, low current. But we already do that to pretty much arbitrarily lower Ωlosses on high V lines - the USSR made a transcontinental line back in the sixties with MV (yup, mega volts).

Could be done, question is the cost (and possibly global production of superconductors: I hear recent increases in fusion experiments are due to a recent increase in superconductor availability, but that in turn implies global production is pretty low). There is a plan for a 5 GW superconducting connection, but AFAIK the ones which have actually been built are in the megawatt range: https://en.m.wikipedia.org/wiki/Tres_Amigas_SuperStation

Similarly, what is the present feasibility of energy transmission via laser using satellites?

We’re at the prototypes and proof of concept stage for that sort of thing.

Optimistically, it’s just about possible in principle if you don’t mind paying SpaceX to expand by a few orders of magnitude. But I don’t think anyone will be very happy with even one gigawatt of orbital lasers, no matter how much the satellite owner insists (possibly even accurately and with reference to the laws of physics) that it can’t be turned into a death ray.

(And if you can use beamed power safely from orbit, with emphasis on safely, why not use the same beamed power horizontally at ground level around the world? Power at night from space implies an orbital-to-ground distance comparable to planetary radius).

Every foil wrapped turd in space is in theory a kinetic impactor by value of location and acceleration.

There was a scifi short story, were a system was wrecked, aeons after a war, by what was essentially missed shots.

This is what makes the expanse so creepy. Every PDC round not finding a target- finds a target eventually. On the other side of the system, totally not intended, but it finds one. Even thinks doing the marathon with ion-engines can become lethally over time.

Voyager is another systems bullet.

If it rains for a week?

The pithy answer is “That’s why people build them in deserts.” However, electric grids need excess capacity spread across large areas for when demand spikes and stuff breaks. Luckily peak demand doesn’t line up with wide scale rain as AC demand falls.

Also, PV unlike concentrated solar does produce power during storms it’s just significantly less than normal.

Reminder that other "low value energy demand" is easy bufferable - one can easy heat water in a isolated ground tank with excess solar and use that storage in winter.

You have ruffled many feathers…
