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.

He probably has corrected his stance already in a different video.

He has quite a few where he was utterly wrong, and has a follow up video that corrects.

Batteries have extremely low losses, the total efficiency of a system easy reaches 95% or more.

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

For the 24 hours: As energy discharged/charged = 13.1 kWh/15.3 kWh = 85.62%.
  For one month: As energy discharged/charged = 386.5 kWh/460 kWh = 84.02%.

Ideally, both should be 90% as per the RTE in the data sheet. The reasons why the real-world
efficiency is lower are:
  The battery was charged and discharged at a low power level (around 300 W for most of the time).
  The battery was idle for long hours, thereby causing idle losses.
The one-month data shows a lower efficiency number since the tare loss keeps building each day, and
the battery charge and discharge each day are not the same.

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.

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.

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

So 911 operators wind up spending a substantial amount of their time redirecting people, e.g., "wait until business hours and then call XYZ". Or they forward calls. Or they do the best they can to help out (sometimes very upset) people who've called 911 because they're desperate.

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"

These facilities have fire suppression. Lots of it, with massive water reserves and often diesel pumps in case the electricity supply goes down....

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

Comment 833,333 GBP per fire avg? (Score 2, Interesting) 59

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.

Here where I am - somewhere in South Florida - FPL has consistently jacked up our rates, for a variety of stated reasons - including feeding the new colos.

Your experience != everyone else's.

My power bill has increased by about 20% DESPITE switching to LED lighting, which reduced my light draw from about 700w to maybe 50w for the whole house minus home cine and bathroom.

My power bill has increased DESPITE setting higher aircon temps.

So yes -- datacenters are absolutely jacking up rates, and have completely made irrelevant the change to LED.

I want my tungsten lamps back. A pox on the next son of a bitch who mandates a switch to a "higher efficiency" light, only see all those gains in efficiency wiped out by a much bigger power user.

According to some good ol AI research (spot checked otherwise) the increase in costs in South Florida have mostly to do with natural gas prices and also some surcharges from hurricanes.

Also, even in the incandescent era apparently lighting accounted for ~ 12% of electricity usage in Florida (on average. for residences). So... not much savings to be had there compared to the A/C.

as to my power bill... well... as Brave AI says:

[costs] have surged dramatically over the past decade, with baseline Tier 1 rates tripling from approximately $0.13–$0.16 per kWh in 2014 to roughly $0.33–$0.42 per kWh in recent years. This represents a total increase of 92% to 118% over ten years, far outpacing the 34% rise in general inflation during the same period.
