You get these nice patterns from Liukuri. No wonder one ‘beats’ the average spot price of exchange electricity every month when the hourly consumption curve for a couple of years looks like this. The cheap hours of the night go to the car and the downstairs floor heating. I don’t bother optimizing other machines for the night, as their consumption is just noise or impossible.

If hot water comes from an electric water heater, heating it during the cheap hours of the night makes a difference.

Eletra Energia. No delivery fee and no margin for 6 months. Even after that, a pretty good offer. Valid until further notice.

Yes, of course.

And in a way, those who became customers got what they ordered, even if they didn’t get what they ordered:
“The company had marketed the electricity contract as consisting solely of the spot electricity price and a fixed basic fee. The fee charged for too low consumption was not mentioned in the website advertisements; according to the Consumer Ombudsman, it was a hidden fee.”
I will continue to actively shop around for my electricity contract, but I will stay far away from these dubious companies.

Optimizing heating during the night, of course, only applies to heating a storage tank large enough for consumption. A small storage tank or a dishwasher connected (quite unnecessarily) to hot water makes heating necessary not only during the night but also during cheap midday hours or even continuously, so no one should be blamed for that.
I, at least, meant cost optimizations made without residents noticing and without compromising living comfort. In our case, the settings of the boiler, which was replaced during the plumbing renovation and heats between 1 and 5 AM, were calibrated by measuring the hot water temperature in the evening. The external temperature limiter of the storage tank is at its maximum, so it doesn’t limit at all; instead, the storage tank’s thermostat was adjusted until the target hot water temperature of 65° from the tap was also reached in the evening.
This provides an additional optimization parameter for exchange electricity once distribution companies can start charging households a power fee. This mainly concerns detached houses with hot water heaters, electric saunas, electric heating (including ground source heat pumps boosted with resistors in cold weather), rechargeable cars, etc.
The regulation is still being drafted, but according to the draft, the monthly power charge would be based on the single highest 15-minute period of each individual household, regardless of whether there is any capacity restriction at that particular moment (e.g., typically at night) naturally or otherwise… And for the part exceeding 5kW. It’s advisable to monitor so that sauna heating and car charging, or sauna heating and house heating, don’t accidentally get left on at the same time.
Well, one gets used to many things, but it’s quite easy to get a ‘electricity fine’ supported by the state if things proceed as described in the article…

The state needs money, and homeowners, on average, have some, so they’re being squeezed. How on earth do you solve the problem of homeowners using electricity when it’s most available and demand is lowest? For example, charging a car at night while the house heats up at night.

Do forum members have any tips for affordable electricity contracts for housing companies? What kind of range have your fixed-term, longer contracts
Väre offers a price fix for 2026 at 6.33 c/kWh.
It’s somewhat interesting, but I think I’ll stick with spot electricity for now. My own rolling 12-month price is currently around 5 cents.

It’s not the state that’s extracting here, but the electricity transmission

Housing company contract prices are often higher than consumer contracts because a housing company is a business entity with a business ID, meaning the contract terms are different. Of course, there can be benefits in some situations if large consumption volumes are put out to tender, but even those benefits may have decreased in recent years.

But the state is ramming this reform through. It feels a bit like with taxi meters and many other things, about all of which one can ask the question:
* Does the state have to be involved in messing things up here too?
Does anyone still remember the deregulation drive?

It seems that at least not all transmission companies are in favor of this. An excerpt from Yle’s article:

Helen has 6 months for a good price. I’d like to cancel the 12-month contract I made last week and switch to 6 months.

I was about to switch to Helen for 6.66€/kWh, when Väre came with an even better counter-offer
