What is the difference between the mFRR energy market and the mFRR capacity market?

In the mFRR capacity market, trading takes place from seven days before delivery up until the day before. Market participants are compensated for the capacity that is called upon. A called bid in the capacity market entails a commitment from the participant to submit an equal or larger bid in the energy activation market.

The energy activation market is traded from the day before delivery until 45 minutes before the delivery hour, and participants are compensated for the energy that is actually activated.
