Example of balance calculation
Example of balance calculation. The example concerns a balance responsible party whose actual production 60 MWh, actual consumption -40 MWh, and sales to day ahead market -30 MWh.
An example calculation of imbalance. The initial data in the example includes a balance responsible party whose realized production during the balance settlement period is 60 MWh, realized consumption is -40 MWh, and day-ahead market sales are -30 MWh.
Composition of balance
- actual production total 60 MWh
- sales to day ahead market -30 MWh
- actual consumption total -40 MWh
The balance responsible party’s balance deviation (imbalance) is a deficit of -10 MWh. In order to cover this, Fingrid will sell balance energy to the balance responsible party at the sales price of imbalance energy.
On May 22, 2023, the 15-minute balance settlement period was introduced instead of the 60-minute balance settlement period.
Prices of imbalance energy
The imbalance price will be calculated to take into account both automatic Frequency Restoration Reserve (aFRR) and manual Frequency Restoration Reserve (mFRR) components, in accordance with the energy balancing guidelines. As of 1 June 2026, the imbalance price will be calculated on a volume-weighted average of these energy prices. More detailed description of calculation and examples are available as attachments.
Additionally, the balance responsible party pays the volume fee for the net balance deviation of imbalance settlement period (from September 2025, the volume fee for the balance deviation will apply to the 15-minute balance deviation).
