Who transmits electricity to the house at night? The lines will be sized for full loads.
- kragen 4y agotransmission lines do not connect to houses, so it is not clear that you understand the distinction i am asking about
- landemva 4y agoThere are various lines at various voltages. Some are 18k+. In commercial manufacturing may be 13.8k, which is further stepped down to 480 and 220 and 110. The point is that unless a residence can independently provide for their own electricity every hour of the day, then the generation and distribution will be sized for full load.
- kragen 4y agoit still seems that you are unaware of the distinction i was focusing on between transmission systems and distribution systems a residence that can provide some of its own power during peak hours does not need distribution, transmission, or (utility-scale) generation sized for full load; a neighborhood that can provide some of its own power during peak hours does not need transmission or (utility-scale) generation sized for full load, just distribution. this is a much less onerous requirement than the one you erroneously believe to be necessary
- landemva 4y agoWho can generate at peak load, reliably, every hour of the day? Some areas have peak load in evening, when PV output is reduced.
- coryrc 4y agoMost of the components don't have a meaningful "maximum load". There's a load with 40-year life, a load with 10-year life, and a load with 160-year life (and obviously this is a continuous curve). It's okay to spend some time at 10-year life load if you can spend more time at the 160-year load than the typical model expects.
- kragen 4y agothings like transformers have a 1-minute load which, if you don't exceed it, they'll last 40 years, but if you exceed it significantly, they'll often catch on fire and explode within a few minutes it's true that there's probably a load right at the rated load which will gradually cook the transformer over the course of 10 years or so, but that's a pretty narrow window that's the kind of capacity that needs to be expanded
- coryrc 4y agoIt's a far wider window than you think.
- kragen 4y agoi can't make any kind of sense out of your comment
- pyrale 4y agoDoesn't really change the point. Current infrastructures are rarely built to have distribution networks feed back into the HT grid. They are also not as monitored as the HT grid is. This may change in the future, but until some politician cares enough and passes the cost on to the taxpayer, there's going to be friction for these changes.
