The price of the last activated down-regulation bid. The price is published real-time when Finland is a separate regulation area. Finland is an own separate regulation area in a situation where the border transmission connections between Finland and the Nordic countries are fully operational, which means that no more balancing energy can be exported to the other Nordic countries. In this case, only Finnish offers can be used. The balancing energy market is used to balance electricity production and consumption in real time. Fingrid orders up- or down-regulation, i.e. balancing energy, from the balancing energy market as needed. Down-regulation can be a reduction in production or an increase in consumption and the price for down-regulation is determined by the cheapest down-regulation offer used. In situations where Fingrid has activated balancing energy for purposes other than balancing, the published price may differ from the final price for balancing energy. The published price is indicative.

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. 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 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 Central Sweden (SE3). 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 = 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.

Aggregate hourly metering data for small-scale electricity production sites in Finland, categorised by production type and customer type. If no production device has been reported for an electricity production site, or if there are several production devices, production type = Other production. Customer types: company = AB01, consumer = AB02. Production types: AV01 = Hydropower, AV02 = Wind power, AV03 = Nuclear power, AV04 = Gas turbine, AV05 = Diesel engine, AV06 = Solar power, AV07 = Wave power, AV08 = Combined production, AV0 9 = Biopower, AV10 = Other production. The data is derived from metering data and production type data provided to Datahub by Finnish distribution system operators and customer type data provided by electricity suppliers. Production used for own consumption has been deducted from the production data in the metering process, and only the surplus small-scale production actually sold to the distribution system has been registered in Datahub. Therefore small-scale production is not comparable with Fingrid’s other Open Data reports. The data is submitted daily, the calculation interval is 1 month and the latest data is -4 days. Small-scale electricity production reflects the figures available at the time the report was generated and may include partially estimated metering data. Estimated metering data is generally corrected within 11 days. The Value attribute contains electricity consumption measured in kilowatt-hours (kWh), and the Count attribute contains the number of accounting points. The data is available starting from 1.8.2023.
