Methodology

Capacity prices reward being available, regardless of whether activation happens. Fingrid procures mFRR capacity and publishes the hourly up/down procurement price (EUR/MW/h).

This is the Finnish (Nordic) procurement price; it is not part of the Baltic Balancing Capacity Market (BBCM).

FAQ

Is this the same market as the Baltic BBCM?
No. The Baltic capacity feed is the joint Baltic Balancing Capacity Market (BBCM). Finland procures mFRR capacity nationally through Fingrid; this is that Finnish price.
