Transmission tariffs and service prices

You will find our transmission tariffs and service price list here. In addition to transmission tariffs, the tariffs also contain the calculation methods for the daily imbalance charge, the excess capacity charge and the centralised information exchange prices.

Under the Finnish Natural Gas Market Act, the transmission system operator sets the transmission charges for Finland’s internal entry and exit points. As regards international connections, the transmission charges for 2020 and 2021 are set by the Energy Authority.

* Set by the Energy Authority

Starting from 1 January 2020, the postage stamp methodology is applied as the reference price methodology in the Finnish gas entry and exit system. In the postage stamp methodology, the distance between entry and exit points or the technical transmission capacity do not affect the unit price of transmission capacity. The postage stamp methodology is applied to capacity tariffs. A capacity charge is applied both to entry and exit capacity.

The price of a capacity product depends on the duration of the product – the longer the duration of the capacity product, the lower the price. We offer annual, quarterly, monthly, daily and within-day capacity products. In addition to the capacity-based tariff, we levy a commodity charge in the exit zone that is lower than the capacity tariff to cover variable costs arising from gas transmission.

Underutilization fee (set by the Energy Authority)

Underutilization fee is applicable in the Balticconnector interconnection point and it is applied only
during days, when Balticconnector is congested. 

A Shipper may renominate downward in the Balticconnector free of charge a maximum of 50 000 kWh/h (tolerance) compared to the Shipper’s highest Confirmed Nomination for the Gas Day. For amounts exceeding the tolerance limit, the Shipper shall pay an underutilization fee.

Tolerance: 50 000 kWh/h
Pricing: 0,002 €/kWh

Pricing for connections

TSO has obligation to connect new infrastructure to its grid as long as connecting infrastructure fulfills technical requirements set by the TSO. Connecting infrastructure may consist of natural gas usage or storage facilities as well as LNG or biogas infrastructure. TSO is justified to collect all reasonable costs which have been generated because of the new connection. 

Pricing: Price of the connection is evaluated case by case

Nomination imbalance charge

A nomination imbalance charge may be applied in Finnish exit zone. 

Pricing: 0 €/kWh

Capacity overrun charge

A Capacity overrun charge is paid in Finland’s exit zone and at the biogas virtual entry point.

Finland’s exit zone: Should, based on the results of the final balance settlement, offtake from the shipper’s system in Finland’s exit zone exceed the shipper’s total capacity for each gas day in the exit zone, the shipper must pay capacity overrun charge. 

Biogas virtual entry point: Should, based on the results of the final balance settlement, injection into the shipper’s system at the biogas virtual entry point exceed the shipper’s total capacity for each gas day at the biogas virtual entry point, the shipper must pay capacity overrun charge. 

Capacity overrun charge pricing: One and a half (1,5) times the unit price based on intraday firm capacity will be charged for the quantity exceeding the reserved capacity.

Daily imbalance charge

Buy and sell prices of balance gas

The transmission system operator with system responsibility’s definition for neutral gas price

Neutral gas price is the weighted average price of intraday products on the Gas Exchange in €/kWh
during the gas day.

Balance gas buy price of the transmission system operator with system responsibility
Step 1: Neutral gas price less 0.5% of the neutral gas price
Step 2: Neutral gas price less 3.0% of the neutral gas price

Marginal price of purchase: Lowest price of the following:

1. Trading price (weighted average) of the transmission system operator with system responsibility
for intraday products on the gas day concerned if the imbalance forecast in the system has been in
the yellow zone (TSO has participated in trading at gas exchange) during the gas day or
2. the applicable adapted price (step 1 or 2). Nevertheless, the price may not be lower than 65% of
the neutral gas price.

The balance gas sell price of the transmission system operator with system responsibility
Step 1: Neutral gas price plus 0.5% of the neutral gas price
Step 2: Neutral gas price plus 3.0% of the neutral gas price

Marginal price of sale: Highest price of the following:

1. Trading price (weighted average) of the transmission system operator with system responsibility
for intraday products on the gas day concerned if the imbalance forecast in the system has been in
the yellow zone (TSO has participated in trading at gas exchange) during the gas day or
2. the applicable adapted price (step 1 or 2). Nevertheless, the price may not be higher than 135% of
the neutral gas price.

Once the competent authority has announced that a crisis level in the supply is in force, the
transmission system operator with system responsibility may, authorized by the competent authority,
determine the pricing of balance gas in some other way.

Balance gas price cannot be higher than 150 €/MWh.

Compensation for non-conformity with gas quality and supply requirements

Compensation terms and conditions have been mentioned in the shipper’s framework agreement.

Charges in a prevailing emergency situation

Compensation is agreed separately case by case between the transmission system operator with system responsibility and the shipper.

Capacity right transfer charge

Pricing: 0 €/transfer notification

Centralized data exchange charge (=Datahub)

The charge is applied to cover the investment and development costs of the centralized data exchange and the transmission system operator with system responsibility does not profit from the charges. The distribution system operator is charged with regard to the consumption sites in distribution networks owned or operated by the distribution system operator for which information is maintained in the register of centralized data exchange system (= all daily or non-daily read metering sites in the distribution network except for individual non-daily read gas cooker sites).

Pricing: 1,25 €/metering site/month

Transmission tariff calculation example

For illustrative purposes only, non-binding example calculations for use of the firm transmission capacity price list.

Example 1: Annual capacity 

The shipper estimates that it requires transmission capacity at an average capacity of 100 MW
(=total transmission requirement during a gas day is 100 MW x 24 h/gas day = 2 400 MWh/gas day) throughout the year. For this, the shipper books the required entry capacity from Imatra and the exit capacity for Finland’s exit zone.

Use the unit price of the entry capacity at Imatra to obtain the transmission capacity from Imatra
1 kWh/gas day for a year. If the annual order lasts 365 days, the unit price 0.14277 € equates to a
transmission quantity of 365 kWh (0.365 MWh). The total transmission quantity required by the
shipper is 2 400 MWh/day x 365 days = 876 000 MWh. In which case the shipper requires
876 000 MWh/0.365 MWh/unit = 2 400 000 units of entry capacity. The unit price is 0.14277 €/unit, in other words the total cost is 0.14277 €/unit x 2 400 000 units = 342 648 €. The average cost of entry capacity is 342 648 €/876 000 MWh = 0.3912 €/MWh.

Use the unit price of the exit capacity in Finland’s exit zone to get the transmission capacity to the
exit point 1 kWh/gas day for a year. If the annual order lasts 365 days, the unit price 1,04859 € equates to a transmission quantity of 365 kWh (0.365 MWh). The total transmission quantity required by the shipper is 2 400 MWh/day x 365 days = 876 000 MWh. In which case the shipper requires 876 000 MWh/0.365 MWh/unit = 2 400 000 units of exit capacity. The unit price is 1.04859 €, in other words the total cost is 1.04859 €/unit x 2 400 000 units = 2 516 616 €. The average cost of exit capacity is 2 516 616 €/876 000 MWh = 2,8728 €/MWh.

The average cost of the capacity booking is therefore 0.3912 €/MWh + 2,8728 €/MWh = 3,264 €/MWh.
