Energinet publishes MARI activation market explainer for Danish operators

Energinet released two balancing-focused publications. The first covers MARI, the pan-European manually activated Frequency Restoration Reserve (mFRR) energy activation platform. The document is directed at Danish market participants navigating cross-border mFRR scheduling and activation under the MARI framework shared across participating TSOs.

The second publication targets a more specific problem: how to dimension reserves and maintain balancing for Danish energy islands. Energy islands sit outside the standard bidding zone topology of DK1 and DK2, creating distinct challenges for reserve sizing, activation sequencing, and real-time balance management. Energinet's guidance addresses those structural differences directly.

Neither document disclosed quantitative targets for reserve volumes or activation prices. Analysts seeking figures on Danish mFRR procurement or MARI clearing data should refer to Energinet's operational transparency portal alongside these publications.
