mFRR, manual Frequency Restoration Reserve

Fingrid maintains the Nordic mFRR energy market together with the other Nordic transmission system operators (TSOs). Reserve suppliers can submit bids to the mFRR energy market for the assets in their control. 

Each Nordic TSO will activate the necessary amount of bids in the mFRR energy market to cover the forecasted or detected imbalances in their control area and to maintain the system security of the electricity system in normal operating conditions and disturbances. Fingrid pays the reserve supplier for the energy activated in the mFRR energy market in case of up-regulation, or the reserve supplier pays Fingrid in case of down-regulation. 

Fingrid procures capacity from the mFRR capacity market to ensure that there is sufficient amount of mFRR at any given time to maintain the power balance between production and consumption and for other needs required to ensure the operational security of the transmission network. In the mFRR capacity market, the reserve supplier undertakes to submit a number of mFRR energy offers to the mFRR energy market corresponding to the capacity offers accepted in the tendering process and receives capacity compensation for the capacity it maintains. 

Participation in the mFRR energy and capacity market requires a balancing power market agreement with Fingrid and either a balancing service provider’s settlement agreement or an imbalance settlement agreement with the imbalance settlement unit eSett, as eSett performs the invoicing of mFRR energy. More information about these contracts and the invoicing model is availableon the eSett website 

The mFRR energy market is currently being developed and the intention is for the Nordic mFRR energy market to become part of the Europe-wide reserve market.  

 

The mFRR market agreements are consistent in terms and content and are publicly available.

Data on the mFRR reserve market can be found on the Reserve Market Information page and on the Fingrid Open Data service.
