Terms of the contract - Exchange Electricity

The contract and prices are valid until further notice. Energy price is based on the hourly price of the Nordic Power Exchange to which a margin is added. In addition, a monthly basic charge is charged.

The contract enters into force according to the start date notified to Helen by the distribution system operator. If the customer's valid fixed-term contract prevents the contract from entering into force on the desired date, the start of the new contract will be moved to the end of the current fixed-term contract, however, no later than 6 months after the original preferred sales start date. Once the order has entered into force, the customer will be sent a notification of it by email.

The contract and prices are valid until further notice. The contract may be terminated by the customer with two weeks’ period of notice. The period of notice by the vendor is 30 days. The terms of electricity sales and the general price lists of Helen valid at any given time shall be applied to the contract. The prices include value added tax.

The price consists of the basic charge and the energy price. The energy price is calculated as monthly average price. Energy prices are determined from the price of the Nordic Power Exchange (Nord Pool) in the Finnish price area as follows: the monthly average energy price is obtained by weighting the prices by the hour with the values of the customer profile curve selected for the customer by the distribution system operator. Value added tax and margin valid at any given time will also be added to the value thus obtained.

If the customer’s electricity consumption is metered and recorded by the hour, hour-based metering information is used in the billing.

Separate, weighted average prices are calculated for day and night periods and for winter day and other time periods using the time division of the Helsinki region with respect to time-of-day electricity A and the time division according to the national metering recommendation with respect to time-of-day electricity D and seasonal electricity. The pricing of the time-of-day product to be applied depends on the number of weekly night-time hours in the time division used by the local system operator.

Currently, the number of night-time hours in accordance with time-of-day electricity A (85–120) is used in the areas of Helen and Vantaa Energy. Other areas are using the number of night-time hours in accordance with time-of-day electricity D (40–84). When selling seasonal electricity, the validity of the price for winter-day energy must be at least 10 hours on working days in the winter season. The winter season is a continuous period of at least four months, starting on 1 December at the latest and ending on 28 February at the earliest.

The offer is meant for permanent dwellings and holiday homes with a main fuse of up to 63 A.

Electricity distribution and metering

Helen shall terminate the current electricity contract with the customer’s authorisation and, when necessary, draw up a new electricity network contract in the customer’s name. The distribution system operator will charge the customer for electricity distribution according to its price list. The distribution system operator is responsible for metering and its billing. In the case of time-of-day and seasonal electricity, the place of use must have 2-rate metering. If the product on offer is not suitable for the time division used by the distribution system operator or the customer’s metering system, Helen is entitled to use a suitable product.


The customer is billed according to the billing frequency chosen by the customer.
