Energinet publishes ancillary services and grid frequency statistics

Energinet released its historical statistics report for ancillary services and grid frequency in April 2026, providing a structured data reference for balancing market activity in Denmark. The publication covers procurement across reserve product categories and records grid frequency behaviour over time in the DK1 and DK2 bidding zones.

The dataset is a standard annual release from the Danish TSO and is used by market participants to benchmark reserve costs, assess frequency quality trends, and inform trading strategies in the Nordic balancing markets. Specific volume and cost figures are contained within the report itself rather than in the published headline.

No additional commentary was issued alongside the release. Analysts requiring product-level breakdowns (FCR, aFRR, mFRR) should access the full dataset via Energinet directly.
