Finnish wind power generation forecast for the next 72 hours. The forecast is updated every 15 minutes. The forecast is based on production measurements from individual wind parks, weather forecasts from multiple providers, and data about the location, size and capacity of wind turbines. The forecast takes into account the effect of Day Ahead electricity price on wind power production. The electricity price is included at 15:30 on the previous day. The data before 31.05.2023 is in hourly resolution.

This is the total wind production capacity used in Fingrid's wind power forecast. It is based on capacity information gathered by Fingrid and actual production measurements. This total capacity information can be used, for example, to calculate the rate of production of wind power, by comparing it to the actual wind production series by Fingrid. The capacity value is updated manually approximately weekly when there have been changes in production capacity. This capacity information cannot however be considered as the official amount of wind production capacity in Finland, as the data is updated retroactively according to actual achieved production.

Finnish wind power generation forecasts for the next day. The forecast is updated every day at 12 p.m. EET. The length of the forecast is 24 hours. The forecast is based on production measurements from individual wind parks, weather forecasts from multiple providers, and data about the location, size and capacity of wind turbines. The day ahead price is known for the first hour of the day at the time the forecast is made, and the price is considered in the forecast for that hour. The data before 28.03.2024 is in hourly resolution.

Wind power production based on the real-time measurements in Fingrid's operation control system. About two percent of the production capacity is estimated as measurements aren't available. The data is updated every 3 minutes.

The values in the data have been erroneously instantaneous values. From February 21, 2024, the data are correct 15-minute averages. The older average data can be found correctly on the European transparency platform: https://transparency.entsoe.eu/generation/r2/actualGenerationPerProductionType/show Finnish 15 min wind power generation is a sum of measurements from wind parks supplied to Fingrid and of the estimate Fingrid makes from non-measured wind parks. Non-measured wind parks are about two percent of the production capacity. 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.

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 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.
