No it doesn't, and you aren't think about it much at all if you think it does. 15kw gets real small when spread across 15 houses that each have 3kw air conditioners. It doesn't even take a hot day. The average oven can easily pull that too.
Someone picked the wrong numbers. Even older homes tend to have 100A panels, in newer homes 150A and even 200A are more common.
It sounds like he's presenting a real edge case but not making it clear that its an edge case.
- mikeyouse 4y agoOf course nobody is using 1kw in lighting any more, so the contrived example is already out of date. I don't know what to tell you, the utility engineer is exactly right and 37.5kv transformers serving 15 houses was a completely standard amount of power to be delivered in the past -- which is exactly his point. All of the heat pumps and electric cars are going to require massive infrastructure upgrades because many neighborhoods are still served by the old infra.
- _ea1k 4y agoI guess I wouldn't have had an issue if he had said these were tiny homes, with mostly gas appliances, gas heat (if any) and no air conditioner. That's a completely different world from most of the country. But to me the kicker is that he went into no further detail. Transformer setups like that are done with knowledge that overloading can happen. If your defending him, then you'd surely know all about how much and for how long, right? Instead, he just said 2kw per house, which is literally absurd.
