Yeah. Those claims are just some random AI slop from claude..

That's not necessarily true, you can have multiple cache points, see e.g. https://platform.claude.com/docs/en/build-with-claude/prompt...

Why would a salesperson rubber stamp product decisions? Even if yes, there are other roles that approved the changes.

This is very standard stuff in Finland for decades. And before heat pumps became popular large tanks were common and those were heated during the night.

The problem still exists up north where solar produces about zero energy for months. Of course, wind power is option there.

That depends on the consumer (and market I guess). In many countries in Europe that is an option. (Although there should be some extra fees on top).

The explanation is lack of interconnect, not losses in transmission. If you have enough capacity to transfer electricity the prices will be equal in two neighboring electricity markets.

Empirically this doesn't seem to happen.

Finland is probably like 15000 kWh/year/house (for a new house more like 10000 kWh/year). All the heating of the house & water is done by electricity, though.

Yes, 4€/kWh, which is dynamically adjusted (if that spot price is reached).

Europe has a max price and prices are determined on the previous day.

I'm not expert in the system in California, but usually consumers are already paying the average spot price (plus some significant margin, which takes into consideration the demand profile of the consumer). Switching to spot pricing wo

In a spot price system you can use electricity when the price is higher than average.

A house will not cool down immediately. It will cool down rather slowly in most cases (or at least if it's well built). There are also various ways to store thermal energy or use alternative, non-electric heat sources. If the price goe

In Nordpool the prices are set the day behind so there's no surprise bill. If the spot price goes up one actually should pay more, which incentives reducing electricity consumption. I think your apartment complex example is not that re

96% of Norwegians use a spot price contract. Seems to work just fine.

You can set a sensible max price, like sensible spot price system do.

Seems like a lot of complexity that can be solved by simple spot pricing for electricity. With spot pricing you can decouple solar and battery storage, as battery owners can make a profit by storing electricity when it's cheap and sell

Counterpoint: kitchens were separate also in countries where the cooking was not commonly done by "the help".

Properly designed heat pump system includes backup for the coldest days - usually direct electric heating. Most houses in Finland have a (decent) fireplace for heating in case of an electric outage.

Selling electricity at wholesale rate is an incentive.

Apparently not generating power will cause the panel to slightly overheat which will add additional tear on the panel, so it might make sense to pay the negative prices instead. Note that electricity generated will first be used by the cons

Are you saying the price is negative during high PV production? In sane markets like Finland solar panel owners need to pay for generating electricity to the grid if the price is negative (which is it sometimes).

The reasoning is that it incentives electricity producers to offer max amount of electricity at low prices without speculating how to maximize profit (as their sell offer will practically speaking have zero effect on the spot price). Nuclea

That is exactly how it works in Finland.

You just need nuclear and existing hydropower, which boils down to you just need nuclear. It's not politically probable or realistic though, but we really just need nuclear technically speaking. Nuclear can also follow loads, but there
