The price of consumption imbalance power is the price for which Fingrid both purchases imbalance power from a balance responsible party and sells it to one. In the case of regulating hour, the regulation price is used. If no regulation has been made, the Elspot FIN price is used as the purchase and selling price of consumption imbalance power. Data gathering to Excel-sheet or XML format is possible in periods not longer that one year due to limitations in data transmission. Separate consumption imbalance ended when 1.11.2021 01.00 settlement model was changed to single imbalance.

Electricity consumption in Finland is based on Fingrid's production measurements. Minor part of production which is not measured is estimated. The consumption is calculated as follows: Consumption = Production + Import - Export. The average shown every quarter is the average of the past quarter, i.e. the value coming with a time stamp of 14:15 is the average from 14:00-14:15. The data before 13.06.2023 is in hourly resolution.

Aggregate hourly metering data for electricity accounting points in Finland, categorised by metering methods. Metering methods: E13 = Continunous metering, E14 = Reading metering, E16 = Unmetered. The data is derived from metering data and metering method data provided to Datahub by Finnish distribution system operators. For accounting points with small-scale production, the production has been deducted from the metering data. Therefore consumption is not comparable with Fingrid’s other Open Data reports.

The data describes the total installed capacity of electricity storage facilities in Finland. The data includes estimates for all electricity storage facilities with a capacity of over 1 MW that are licensed to operate in the electricity market. The capacity data used describes the technical capacity of the electricity storage facility and does not take into account any capacity restrictions arising from agreements. The capacity is calculated from the electricity storage facilities added to the network model, most of which are added before production begins. The data includes electricity storage facilities that will be put into production within approximately one month. The capacity connected to the distribution network depends on the documentation provided by the distribution network companies, which also prevents the provision of accurate figures.

The data is a 15 minute average that is calculated every 15 minutes. The estimate is based on electricity generation measurements and the used fuel types published by the generators. The electricity generators have been categorised into fuel type groups. Some of the fuel type groups are assumed to generate electricity without burning fossil fuels. The fuel type groups for electricity generation are corresponding with the electricity generation categorisations of the ENTSO-E transparency platform. Fuel type groups ‘Biomass’, ‘Solar’, ‘Wind Onshore’, ‘Hydro run-off river and poundage’, ‘Other renewable’ and ‘Nuclear’ are considered non-fossil electricity generation. Power plants categorised as ‘Biomass’ or ‘Other renewable’ may burn some fossil fuels in their electricity generation. Thereby, this dataset is not an official statistic of the non-fossil electricity generation in Finland. Rather it is a near real-time estimation. The dataset was first published in June 2025. The data is provided retroactively from the beginning of the year 2025.

Congestion income between Finland (FI) and Estonia (EE). Congestion income is published on ENTSO-E's Transparency Platform, which can be founded here: https://transparency.entsoe.eu/transmission/r2/dailyImplicitAllocationsCongestionIncome/show . There are historical values to be found from Open Data until the beginning of February 2017. After February 2017 updated data as well as historical data can be founded from ENTSO-E's Transparency Platform. Congestion income is calculated as follows: congestion income [/h] = commercial flow on day ahead market [MW] * area price difference [/MWh]. Congestion originates in the situation where transmission capacity between bidding zones is not sufficient to fulfill the market demand and the congestion splits the bidding zones into separate price areas. Congestion income arises from the different prices that the sellers receive and the buyers pay when electricity flows from the higher price area to the lower price area. The power exchange receives the difference, which it then pays to the Transmission System Operators (TSOs). The TSOs spend the received congestion income on increasing the transmission capacity on its cross-border interconnectors according to the EU regulation.

There are historical values to be found from Open Data until the beginning of February 2017. After February 2017 updated data as well as historical data can be founded from ENTSO-E's Transparency Platform. Congestion income = commercial flow between FI and SE3 on the day ahead market [MWh/h] * absolute value of price difference between FI and SE3 [/MWh]. Congestion originates in the situation where transmission capacity between bidding zones is not sufficient to fulfill the market demand and the congestion splits the bidding zones into separate price areas. Congestion income arises from the different prices that the sellers receive and the buyers pay when electricity flows from the higher price area to the lower price area. The seller acting in a lower price area receives lower price for electricity compared to the price the other party pays for electricity in the higher price area, and the power exchange receives surplus income, which it then pays to the Transmission System Operators (TSOs). The TSOs spend the received congestion income on increasing the transmission capacity on its cross-border interconnectors according to the EU regulation.

Congestion income between Finland (FI) and Northern Sweden (SE1). Congestion income is published on ENTSO-E's Transparency Platform, which can be founded here: https://transparency.entsoe.eu/transmission/r2/dailyImplicitAllocationsCongestionIncome/show . There are historical values to be found from Open Data until the beginning of February 2017. After February 2017 updated data as well as historical data can be founded from ENTSO-E's Transparency Platform.
