When is electricity cheapest today in Sweden?

How 15-minute electricity pricing works in Sweden, who can benefit from shifting usage, and why your contract and grid tariff matter.

Electricity market prices in Sweden can change every 15 minutes. For some households, that creates a practical opportunity: instead of running the washing machine, dishwasher or EV charger immediately, you can move flexible usage to a cheaper period.

But the key point is that this only matters if your electricity contract actually follows short-term market prices.

Who can benefit from checking 15-minute prices?

The clearest case is a dynamic quarter-hour contract. With this type of agreement, the energy price follows the spot market every 15 minutes, plus the supplier's markup and VAT.

According to the Swedish Energy Markets Inspectorate, the next day's spot prices are set at around 13:00. That means you can normally see the cheaper and more expensive periods in advance and plan flexible consumption accordingly.

What if you have a monthly variable or fixed-price contract?

Then moving an appliance to a cheaper spot-price period will usually not change the energy price you pay for that specific use. With a monthly price, the same calculated energy price applies across the month regardless of the exact time of day. A fixed-price contract is likewise not tied to each 15-minute spot interval.

So before chasing the day's cheapest period, check what type of contract you have.

What is easiest to shift?

laundry;
dishwasher cycles;
EV charging;
water heating or parts of home heating, where your system supports scheduling.

There is no reliable rule that electricity is always cheapest at night. The cheapest periods vary by day and by Sweden's electricity price area.

A simple routine

Check whether your electricity contract follows short-term spot prices.
Once the next day's prices are available, identify the cheaper periods.
Move only flexible consumption that does not need to happen immediately.
Avoid creating an unnecessary power peak by starting several high-load appliances at the same time.

Why the grid tariff can matter too

If your electricity network tariff includes a power-based fee, your grid cost may also depend on when and how intensively you use electricity. The Swedish Energy Markets Inspectorate therefore advises consumers to consider both the spot price and the grid tariff when shifting consumption.

In other words, a cheap 15-minute market period does not automatically mean that running every high-power appliance at once is the best choice.

The practical takeaway

Check your contract first, then check the cheaper periods. If you are on dynamic pricing, timing can genuinely affect your energy cost. If you pay a monthly average or fixed price, shifting usage purely because the spot market is cheaper at that moment usually will not have the same effect.
