We should probably look for more EW facing vertical installs that leave rows easy to access.
Or even just EW facing vertical installs as wind breaks at field edges...

Doesn't that risk decomposing it into methane?

So gas can backup gas!
The main reliability risk is in the common cause failure of the gas delivery system.
That can be mitigated by making then dual-fuel, with onside liquid fuels storage.
But of course, a reserve margin is needed to cover that they are individually imperfect.

The important thing here though is that their failures tend to be uncorlelated (outside that near design weather aspect, which needs to be accounted for in their reliability ratings), and their scheduled downtime is anti-corrleated (schedules are staggered, and tend to be in shoulder season).

This only works if Ukraine gets a substantial nuclear deterrent.
If we don't like that alternative, maybe something else should be on the table...

And anouther is the common cause failure risk of relying too much on the just in time fuel delivery of natural gas (or hydrogen if we were to ever consider that).

Anouther big factor is a lot of the cost saving is illusory, as there a lot of fixed costs that are being recouped on volumtric basis, that will end out as some form of fixed charges, and that will end out going to the capacity value of the fuel supply system.
The idle systems issue.

And this is a big chunk of why I'm not enthused about the 'default plan' of a natural gas firm system, with solar and wind 'fuel saving' as much as they economically can...

The alien equivalent of viruses would likely be effectively inert, or at least non-spreading(works by hijacking biomachenery, if the bimachinery is different, unlikely to do replaicate, may kill a few cells).
Alien bacteria equivalent, on the other hand, could be terrifying.

The main problem with that is it becomes the grid worst case capacity requirement, right when solar is at a minimum, and wind typically under-performes.

For a highly cyclic service, like FCAS, would that mean you should have an 'A' and 'B' side of your battery, where one side would stay in a charging state, the other in a discharging state (just varrying between 'stipped' and max rate) until they get to their max/min charge levels, then switch?

Does that mean switching the polarity of the cell (my terminology may be off, but going to a voltage lower than open circuit cell voltage to higher than, or vice versa) is a large driver of wear? Along with charge/discharge near the ends of the range are the main drivers?

Yes, lifetime Watt-hours should mean that you have 18x the 60-55 cycles as 100->10 cycles, but both would count as 1x? Say if you get 1111 100->10 cycles (1000 full cycles equivalent), you would get 20k 60->55 cycles (same total WH) but 30k 75->25 cycles (at 15x). So MORE actual cycles even.

Wait, does that mean that short cycles (say 60->55->60) is just as bad for wear as over deep cycles? This is very bad for balancing / grid services applications, no?

"Find all inspection reports that include line xxx-yyy and link to the relevant page" would actually be time saving if it works, and if linked through, each result can be validated.

My understanding from interviews on these was it was more a way to help do things like "find all regulatory references to topic X", or "find all plant data relevant to topic X", and largely save the time for searching, not do the analysis.

To the extent it's used as a fancy search engine, it's probably fine...
Just not revolutionary...

By 'averaging out' I really mean maxing out the connection whenever the price level is vaguely attractive.
As opposed to occasionally hitting that output only when prices are high (peaking).

Of course there should be some storage on the solar gen side, but should we have more than needed to 'near average' the output? There, probably not as you get back into underutilizing the connection capacity like with standalone PV.

10.07.2025 16:21 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Is it trying to use the storage for peaking?
Is this the best location for *peaking* storage, or does your unconstrained transmission assumption just move peaking storage to this location?
(With TX/DX constraints, peaking storage should probably be near load, rather than gen).

Or your last cell tower was in the coverage zone for the alert, the alert went out and was sitting in your message queue based on the last tower you connected to, so as soon as you went back online you received it. Nothing nepharious, just how the system works...

even worse - they have to price in the risk of retroactive claw back of any benefits, so they will have trouble counting them.

Inheritance tax should simply be to zero-basis anything received.
Taxes on non-cash assets should be payable on liquidation (avoiding the 'family farm' argument), and a certain amount could be shielded with the lifetime capitol gains exemption.

With this, we should have a lifetime capitol gains exemption. That is X$ of capitol gains you can exempt from income tax. This exemption replaces tax-free saving accounts, primary residence capitol gains exemptions, and inheritance tax exemptions.
The remaining amount grows with inflation.
