Start date on order and contract confirmation

In most cases, the requested date can be accommodated.

Missing confirmation?
If you don't see the confirmations in your email, check your spam folder. It's also possible that you selected to receive the confirmation by mail instead. Could the confirmations have been sent to your previous address? (Remember to update your address with the postal service!)

How to check your contract start date in Fortum’s online service

For an open ended contract, the contract start date, which is also the electricity supply start date, is displayed. For a fixed-term contract, the contract period shows the start date. You can also easily find the contract start date in the Fortum mobile app. If the start date is not visible, check the contract page link for more details.

The price of electricity is determined through trading based on supply and demand. The hourly wholesale price for the following day, known as the spot price, is set in the Nordic electricity exchange. The prices of long-term contracts are influenced by long-term forecasts and the price hedging mechanisms used in trading.

Several factors affect the formation of the wholesale price, including the type of production, the global market price of fuels used for electricity generation, the cost of emission allowances, and in the Nordic region, particularly the availability of hydropower reserves in Norway.

How the wholesale price affects customer contract prices

• If a customer has a fixed-term fixed-price contract, the energy price remains unchanged throughout the contract period, unless they have the Fortum Vaihtotakuu (Switch Guarantee) service, which allows switching to a more affordable contract after the first year.

• The Fortum Tarkka (Spot price contract) includes its own price management tools.

• With a Fortum Tarkka contract, customers can prepare for rising prices with Price Guarantee, which allows them to lock in a fixed price for specific periods, such as the winter months, to protect against potential price spikes.

If you have a fixed-price electricity contract, we will not change the electricity price during the contract period. This means you know exactly how much you pay per kilowatt-hour, and your bill amount will only vary based on your consumption – that is, how many kilowatt-hours you use.

If you are unsure how long your fixed price is valid, you can check it on your bill or by logging into the online service.

Fixed or spot-priced electricity – which suits you best?

Both types of contracts have their advantages and disadvantages, and the most important thing is to make an informed decision based on what best fits your financial situation and lifestyle.

Living situation

Your type of housing influences whether a fixed price or spot-priced electricity is the better option.

• In detached houses, electricity consumption is usually higher than in apartments, meaning potential price increases in the spot market could significantly impact your finances. On the other hand, you won’t benefit from low electricity prices if they occur.

• Larger homes generally consume more electricity, while cottages and holiday homes may only use electricity part of the time.

• Consider your living situation and estimate how high your electricity consumption is or will be.

Personal finances

If you have a tight monthly budget, a fixed electricity price might be a good choice. You will know exactly how much you pay per kilowatt-hour, and your price won’t change during the contract period. This ensures stable bills and predictability in your finances.

Interest in monitoring electricity prices

If you enjoy following electricity market trends, spot-priced electricity might be the best choice.

• Over time, spot electricity is often cheaper, even though prices fluctuate from hour to hour.

• With the Fortum app, you can track electricity prices in real-time and monitor monthly variations, giving you

  full transparency over your electricity costs.

Certainty vs. Flexibility

• A fixed electricity contract provides certainty, as you always pay the same price per kilowatt-hour. However, you won’t benefit from price drops if market prices decrease.

• The choice depends on you: Do you prefer full control over your electricity costs, or are you willing to accept price fluctuations? Can you handle occasional price spikes if it means paying less at other times?

Ultimately, the right choice depends on your individual needs and lifestyle.

A change is coming to the daily lives of electricity customers summer 2025 – quarter-hour electricity pricing. In the future, electricity spot prices will fluctuate every 15 minutes instead of the current system, where prices are determined for each hour of the day. This means that with spot electricity, there can be up to 96 different prices per day.

Quarter-hour pricing is set to take effect in Finland on June 12, 2025. The goal of this change is to create a more stable and efficient electricity market that better reflects the real variations in electricity demand and production. However, the basic logic of spot electricity will remain the same for customers, but price fluctuations will occur more frequently throughout the day.
