  • It is a real and very common problem that gets no press because a lot of people work very hard to ensure that the line temps do not reach critical. That said, it only becomes a real problem during times of high demand like heat waves and cold snaps. Our infrastructure is absolute dog shit at the moment, and I think the fear is that if every home had one or two EVs charging overnight, then every night would be a high demand event.

    We need to bring our infrastructure up to adequate.

    I think there is a big misunderstanding here. The power grid suffers from a distribution problem not a production problem. The concern with households with EVs is getting the power from the power plants to the houses. During high demand, the powerlines overheat. It’s a delicate power regulation dance to keep the flow at maximum capacity without having fully shutdown any power routes in order to cool. If you do not, you will lose the lines which means a significant downtime for that path.

    Datacenters are getting direct lines from the production sites. I believe that for some datacenters, retired nuclear power plants are being spun up in order to serve them exclusively.

    SOURCE: Grid management is one of the things my firm specializes in.

    EDIT: Believe it or not, households with solar panels that feed back into the grid can be a problem sometimes because the unexpected capacity in the lines can also overheat the lines and hampers the ability of the utility company to regulate lune temps. If you are doing solar, consider adding battery banks to catch the excess.
