Fixed-term Valtti Electricity
A fixed-term electricity contract that offers you price stability and the opportunity to impact the amount of your electricity bill by steering your electricity usage.
Price stability and adjustability
Fixed-term Valtti Electricity is an electricity contract that allows you to combine the benefits of fixed-priced and hourly priced electricity. A fixed electricity price component is set the day you sign the contract, which remains the same throughout the whole contract period. However, you can influence the final monthly electricity price by optimizing your electricity usage during the low-cost hours of the month. This is called usage impact, which decreases or increases the monthly electricity price depending on how you optimize your electricity usage compared to the monthly average price of exchange electricity.

How the price of Fixed-term Valtti Electricity is formed
The price of the Fixed-term Valtti Electricity contract consists of the fixed electricity price component, usage impact, and a monthly basic fee.
The price of the fixed component is set based on the price on the day you sign the contract, and it remains the same throughout the entire contract period. Most of the monthly electricity price forms based on this component.
The usage impact decreases or increases the monthly electricity price depending on how your hourly electricity usage compares to the monthly average price of exchange electricity. You can influence this by optimizing your electricity usage.
If most of your electricity usage occurs during the hours of the month when the exchange electricity price is higher than the monthly average, the monthly price of electricity will increase by the amount of the usage impact. If most of your electricity usage occurs during the hours of the month when the exchange electricity price is lower than the monthly average, the monthly price of electricity will decrease by the amount of the usage impact.
Fixed-term Valtti Electricity contract also has a fixed monthly basic fee that is not dependent on the amount of your electricity consumption. The monthly basic fee remains the same throughout the contract period.
Please note that the calculations provided in this page are examples of usage impact. The actual usage impact may be smaller or larger depending on the timing of your consumption and the actual monthly price of the exchange electricity. If the contract begins in the middle of the month, the usage impact for the first month may be higher or lower than usual.
An example of the usage impact
Fixed component 8,0 c/kWh
45% Usage that decreases the price
25% Usage that increases the price
30% Uncertain impact
Example calculations
Example calculations of the usage impact. In the example, the basic component part is 10 c/kWh. Usage impact in the example is either + 2 c/kWh or - 2 c/kWh.
You have used electricity during lower-priced periods
Impact of usage: - 2 c/kWh
Energy billing price: 10 - 2 = 8 c/kWh
+ basic charge: €/month
You have used electricity during higher-priced periods
Impact of usage: + 2 c/kWh
Energy billing price: 10 + 2 = 12 c/kWh
+ basic charge: €/month
Information about usage impact and steering your electricity consumption
The usage impact is formed when the hourly prices of your electricity consumption are compared to the monthly average price of exchange electricity. The usage impact either increases or decreases the monthly electricity price depending on how you schedule your hourly electricity consumption compared to the monthly average price of exchange electricity.
If you use electricity the most when the exchange electricity price is higher than the monthly average, the usage impact will increase the monthly electricity price. Conversely, if you use electricity the most when the spot electricity price is lower than the monthly average, the usage impact will decrease the monthly electricity price.
The usage impact is determined by month, and its amount resolute by the actual electricity consumption at the usage location.
Monthly average price for exchange electricity (c/kWh)
Lower price (c/kWh): Usage that decreases the price
Higher price (c/kWh): Usage that increases the price
Uncertain impact (c/kWh): No major impact on the price
The usage impact means comparing the hourly prices of your consumption to the monthly average price of electricity in the power exchange.
The calculation formula used is (A-B) / E = c/kWh, which gives the usage impact for the month in question.
A = Your hourly electricity usage (kWh) is multiplied by the hourly price of exchange electricity (c/kWh), after which the products of all hours are added up. As the electricity consumption of different hours and the hourly price of exchange electricity vary to a great extent, the impact of every hour will be taken into account with this calculation formula.
B = Your electricity usage over the whole month (kWh) is multiplied by the monthly average price of exchange electricity (c/kWh). This gives the value for your electricity usage if it complies with the monthly average price of exchange electricity.
E = Your electricity usage over the whole month (kWh)
When figure B is deducted from figure A, you will get the view of how you have consumed electricity in relation to the monthly average price in the power exchange. The figure obtained is divided by the electricity usage of the whole month, which gives you the usage impact for the past month (+/- c/kWh).
The final figure is either negative, in which case the amount of your electricity bill will be decreased, or positive, in which case it will increase the amount of your electricity bill. The more you are able to shift usage to the lower-priced hours of the month, the greater the saving you will make in view of the monthly average.
Please note, that in this electricity contract the invoiced price of electric energy cannot be negative.
Calculation formula for the usage impact after the transition to 15-minute pricing:
The usage impact refers to comparing the 15-minute or hourly prices of own consumption with the monthly mean price for exchange electricity.
The monthly usage impact is calculated using the formula (A-B)/E = c/kWh, where
A = Your 15-minute or hourly electricity consumption (kWh) is multiplied by the spot price (cents/kWh) of the same time, after which all moments of the month are added together. In this way, the usage impact over the month is taken into account, as consumption at different times and the spot price determined in the market vary greatly. If you use an hourly meter, an average is calculated from the spot prices, which is used in calculating the usage impact. If you use a 15-minute meter, the prices for a single quarter are used in the calculation.
B = Is calculated by adding together your total electricity consumption (kWh) for the same month and multiplying it by the monthly average of the spot price for the same month (cents/kWh). In this way, it is possible to calculate the price for total consumption based on the average spot price.
E = your electricity consumption for the entire month (kWh)
(A-B) = Subtract B from A to see how consumption during hours when the price of electricity is lower and higher compares to the average. Whether the value is negative, i.e. decreasing the amount of the invoice, or positive, i.e. increasing the amount of the invoice, depends on whether the largest part of the monthly consumption has been consumed at cheaper or more expensive moments compared to the average for the entire month. The more the monthly consumption can be directed to cheap moments, the more the monthly average can be undercut.
Please note, however, that the invoicing price of electricity cannot be negative in the electricity contract.
Where possible, carry out activities that use a lot of energy, such as doing the laundry, going to sauna, charging an EV, or using electric heating, late in the evening, during the night and at weekends when the price of electricity is lower than average.

Origin of electricity
The origin of the electricity contract without additional services is mixed electricity. The origin of mixed electricity is based on the distribution of electricity production in Finland, from which electricity produced from verified renewable energy sources has been deducted. If you wish, you can update the origin of your contract's electricity with the Renewable or Carbon-Free additional services.
The specific carbon dioxide emissions of mixed electricity are 554.9 g/kWh and the amount of used nuclear fuel is 0.44 mg/kWh. See also the origin and specific emissions of all the electricity we sell.
