Because we live in a universe where its basic attributes are such that they allow that to happen.
so yeah... if they were slightly different these might be nothing of interest here

relatedly,
some postulate that there are infinitely many universes and by "the anthropic principle" we happen to be in one that allows us to exist because by definition we couldn't be in any of the ones that are hostile to our existence. e.g. in universes where gravity is considerably weaker there's no stars or planets... and if there are no stars, then there isn't fusion which is what created all the elements beyond hydrogen (iirc), and therefore no chemistry, and no life, no evolution to increase complexity... etc

hmmm. the with they link in the comments there is reasonably descriptive about what defaults on and what's off.

idk what the chances of changing their policy is, but something like "category 2 should default to off because ..."
Or "installation wizard should allow unchecking of... for cat 1 and 2" would be the way to phrase it but it wind be a political policy battle rather than a tech bug one it looks like.

In this case it seems correct and in line with expectations from Enphase, the battery system provider. This is from one of their docs:

https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fenphase.com%2Fdownload%2Fb...

It's an AC coupled system so solar goes DC -> AC and then the battery is AC -> DC -> AC which is where this percentage is coming from.

(nm on the $207/month isn't right. it's 207/year but just for the electricity roundtrip loss. has nothing to do with the capital costs etc.)

There's a YT guy who just posted his 2 year breakdown on his Massachusetts green house (electric everything, heat pumps, solar + batteries) a few days ago.
There it seems the utility makes heavier usage of his batteries than yours, but decreasing.

channel: "undecided with Matt Farrell". vid title "The Hidden Problem With Home Batteries" is a bit click baity, in that he's quite bullish on the whole thing, basically he's saying he just roundtrip loses 20% of the electricity in his battery, whereas, in MA with the current laws , he can use the grid as "storage" with 0% loss because he has net metering INCLUDING transmission costs.
i.e. if he puts in 1 kwh and takes out 1.5kwh he only pays for 0.5 kwh so he "stored" that 1kwh for free

In his case, even with all the up front tax rebates and with payments from the utility for the peak load shifting the batteries are costing him ~$207 / month over 20 years iirc. (including the installation cost )

No reason to doubt it, but there's no supporting or illustrating operational data in TFA.

Like they mention battery capacity added over 5 years... and better grid interconnects with other regions. But don't show what role specifically either of these played in peak usage scenarios.

like where's the before and after that shows x KW was transferred and allowed higher peak usage with no degradation?

Also, these changes were added over the past 5 years... so why weren't there rolling blackouts in 2021 or 2022? does that mean that everything after that point, which is probably the bulk of the battery storage, was unnecessary?

they can easily require the LCD display on the charger to list the prices and have them updated via software. like the system already knows the price since it is charging you a total, it's not just dispensing unmetered energy.

all gas pumps I've seen in the past 2 decades at least, in the US, have this feature.

mmm. I agree, but this seems like an AI written summary and essay of this basic position.

well done but unlikely to be organic, imo

well, you try architect, and pre-stage, and segregate and all those things to give yourself as many is as possible and as few critical sections and points of no return as possible.

It's not always possible (or just too expensive ) to cover everything, and there's also that thing nobody thought about... but still this one sounds pretty bad. Reading between the lines I'm guessing this want some bigger things, but that they didn't realize that it was happening at first. otherwise, if it's just sw update (vs involving like multiple pieces of core infrastructure) you'd think they could just take the whole center offline and let other places deal with the calls while they fixed this one....
but of course that's just speculation, idk their architecture or what specifically was updated or what.

  would be interesting to see the report on it eventually

oh, but NYC has 311. I haven't used theirs but in the 2 places I have used it... they were more responsive and intellectual curious and engaged than the police/911 ones... at least usually.

my experience over the years calling the police non-emergency number (which also routes to 911 operators in my area) or 911 for urgent but not critical things in a few towns has had the operators be at best "curt, but professional". rarely had one who seemed to care about what was going on or that wanted to help or dispensed actually useful routing advice.

it was usually a "ugh.... fine I'll take down the info because the law probably requires that I do so" vibe. like my existence was tolerated... but "just barely"

Dr. Boz on YT ( https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.youtube.com%2F%40Docto... (check the Live tab which is less clickbaity than her "videos" one)
is a big proponent of it for all purposes. She started from mental health , but switched into advocacy mostly due to her mom's cancer.

She starts her live streams by measuring ketones and glucose. and she's been wearing CGMs for a while. i'm sure she'll pick up this combined device too.

Her Keto Continuum approach i find to be a pretty good way to transition into low carb then nutritional keto and even multi day fasting in a way more likely to succeed than just raw dogging it from SAD.

That's what I assumed and why the 1b GBP in ANNUAL losses number seems so unlikely. let's say 800 million is due to these larger 40 million GBP each losses .. that would be 20 such facilities per year! and still 200m left for the smaller stuff.

I haven't looked into the source for the 1B number but on background I have a hard time believing it

so they're saying 1200 fires cost 1B GBP.
That's 830K GBP average per fire which seems... rather high. Don't these places have some form of on site fire detection and suppression? like some fire hoses or something. These little batteries don't have THAT much energy in them; they're not EVs.

(and yes even EVs you use water on if they catch fire. just a lot of it over a long time. i mean ideally you'd just put it in a container of water and top of the water as needed as it boils off )

my argument is the opposite of ideological: I'm saying there's nothing so bad about datacenters themselves that justifies the level of hate against them.

They've existed and evolved over the past 30 years and the water, noise, and power issues can and should be addressed through normal planning process just like any other industrial building.
