Electricity contract yösähkölle 2026
Night electricity is a traditional two-tariff arrangement where electricity is cheaper at night (typically 10 pm-7 am) and at weekends. It was designed for homes with storage electric heating or a hot water tank. Today spot pricing has largely replaced traditional night electricity because it offers the same benefit more flexibly - the cheap hours are not limited to a fixed time of day.

Which electricity contract suits yösähkölle?
Spot price
Spot pricing is almost always a better choice than the traditional night tariff. It offers the same benefit - cheaper electricity during quiet times - but more flexibly and without a high daytime price. Combined with storage heating and smart control the saving is significant.
Fixed electricity contract
A fixed contract does not exploit the core idea of night electricity, namely timing consumption to the cheapest hours. If you have storage heating or a large hot water tank, a fixed contract means you lose the option to optimise charging times by price.
Estimated annual cost - yösähkö
The estimate is based on average consumption (12,500 kWh/yr). The spot-price estimate is based on a 12-month average price of 7.5 c/kWh (incl. VAT).

Frequently asked questions
Is night electricity still a worthwhile option?
The traditional night tariff has lost its importance because spot pricing offers the same benefit more flexibly. With spot pricing the cheap hours can fall at any time of day - especially on windy days electricity is cheap even during midday. It is worth switching from night electricity to spot pricing.
Why is spot pricing better than night electricity?
With spot pricing the price varies hourly according to real supply and demand. The cheapest hours are often at night, but the price can also be low during the day. With night electricity you pay a fixed night price even when spot pricing would be cheaper. In addition the daytime price of a night-electricity contract is often higher than the average spot price.
How do I switch from night electricity to spot pricing?
Switching is easy: pick a new electricity contract from Sopimusvahti's comparison and sign up online. The old contract ends automatically. The meter does not need to be a two-tariff meter - modern smart meters support both. The switch usually takes two weeks.
Who was night electricity originally designed for?
Night electricity was developed for homes with storage electric heating or a large hot water tank. The idea is that the heat store is charged at night with cheap electricity and releases heat during the day. The same principle works more effectively today with spot pricing and smart control.
How much will I save by switching from night electricity to spot pricing?
A typical saving is 200-600 euros per year depending on consumption. A heavy consumer (20,000 kWh/yr) can save up to 500-800 euros. The saving comes especially from not having to pay the high daytime rate of a night-electricity contract.
Does storage electric heating work with spot pricing?
Yes, and very well. Storage electric heating is designed to charge cheaply and release heat during more expensive times. With spot pricing and smart control the storage charges automatically during the cheapest hours - not only at night, but whenever the price is low.
