What a battery can sell
What ancillary services can a battery sell in Denmark electricity market?
Denmark electricity market has 9 ancillary-service products, across 4 families — frequency containment, automatic frequency restoration, manual frequency restoration and inertia & system strength: automatic Frequency Restoration Reserve; Frequency Containment Reserve; manual Frequency Restoration Reserve; Nordic automatic Frequency Restoration Reserve; Frequency Containment Reserve for Disturbances, downward; Frequency Containment Reserve for Disturbances, upward; Frequency Containment Reserve for Normal operation; Fast Frequency Reserve, and 1 more. Response timing, direction and eligibility for each are in the cards below, as the official sources state them.
Facts below are stated as the official sources state them. A missing line means the
source does not state that value — never that the value is zero.
Frequency containment
Frequency Containment Reserve
operational
Contain frequency deviations before frequency-restoration processes take over.
Direction
symmetric or separate upward/downward according to synchronous area and national procurement
Full activation
30 s
Trigger / range
continuous response to local frequency deviation; exact deadband and droop are national/synchronous-area technical parameters
Eligibility
prequalified generation, storage or demand resources meeting synchronous-area and national TSO requirements
Typical procurement
Dynamic or not publicly stated
Pricing
national/regional rules
Thirty seconds is the Continental Europe full-activation time, not a universal Europe-wide value.
Continental Europe requirement for a frequency deviation of at least 200 mHz; do not apply to Nordic FCR products
Frequency Containment Reserve for Disturbances, downward
operational
Contain over-frequency after a major disturbance.
Direction
downward
Sustain
at least 20 min
Trigger / range
over-frequency disturbance response curve
Eligibility
Nordic prequalification and national BSP registration
Typical procurement
1400 MW
Pricing

The 7.5-second checkpoint is a measurement point, not the point of full activation.
Frequency Containment Reserve for Disturbances, upward
operational
Contain under-frequency after a major disturbance.
Direction
upward
Sustain
at least 20 min
Trigger / range
under-frequency disturbance response curve
Eligibility
Nordic prequalification and national BSP registration

The 7.5-second checkpoint is a measurement point, not the point of full activation.
Frequency Containment Reserve for Normal operation
operational
Continuously regulate small Nordic frequency deviations in normal operation.
Direction
symmetric up and down
Trigger / range
49.9-50.1 Hz normal-operation band
Eligibility
Nordic prequalification and national BSP registration
Typical procurement
600 MW
Pricing
national pay-as-bid or marginal arrangements
Total need is a Nordic dimensioning value, not each country's awarded volume.
Automatic frequency restoration
automatic Frequency Restoration Reserve
operational in participating markets; rollout continued
Restore frequency and area-control error and release FCR after an imbalance.
Direction
separate upward and downward
Full activation
5 min
Trigger / range
activated from TSO control-area needs rather than a single public frequency threshold
Eligibility
prequalified balancing service providers; aggregation rules are national
Typical procurement
Dynamic or not publicly stated
Pricing
capacity pricing is national; common merit-order activation and marginal pricing apply through PICASSO subject to implementation rules
A common balancing-energy product does not imply common national capacity procurement, qualification or settlement.
EU standard-product full activation time; before 18 December 2025 national products and transition rules still apply and have to be checked market by market
Nordic automatic Frequency Restoration Reserve
operational
Automatically restore Nordic frequency and balance after FCR action.
Direction
separate upward and downward
Full activation
5 min
Trigger / range
TSO activation signal
Eligibility
prequalified BSPs
Typical procurement
250 MW
Pricing
national/common market rules by product and period
The Nordic requirement is dynamic and should not be treated as a fixed annual procurement.
Manual frequency restoration
manual Frequency Restoration Reserve
operational in national markets; MARI integration continued
Restore system balance manually or by automated dispatch after faster reserves and release aFRR/FCR.
Direction
separate upward and downward
Full activation
750 s
Sustain
at least 5 min
Trigger / range
TSO activation based on imbalance, reserve need and common merit order; not a single frequency threshold
Eligibility
prequalified balancing service providers; aggregation and telemetry requirements are national
Typical procurement
Dynamic or not publicly stated
Pricing
national capacity rules and common-platform energy pricing under the implementation framework
The 12.5-minute value is a standard-product maximum full-activation time; legacy national tertiary products may use different labels or timings.
maximum full activation time for the EU standard product; legacy national products may differ
Nordic manual Frequency Restoration Reserve
operational; automated Nordic mFRR energy-activation market launched 4 March 2025
Restore balance and release faster reserves using manual or automated TSO dispatch.
Direction
separate upward and downward
Full activation
750 s
Trigger / range
TSO balancing-energy activation
Eligibility
prequalified BSPs
Typical procurement
Dynamic or not publicly stated
Pricing
capacity rules national; energy merit-order activation
Norway also procures a national disturbance variant (mFRR-D); this record describes the common product family.
Inertia & system strength
Fast Frequency Reserve
operational when needed
Arrest rapid frequency decline in low-inertia Nordic operating conditions before FCR-D fully responds.
Direction
upward
Sustain
5 s to 30 s
Trigger / range
procured only when forecast Nordic inertia makes it necessary; activation threshold/profile depends on product variant
Eligibility
prequalified fast storage, demand, generation or other resources
Typical procurement
Dynamic or not publicly stated
Pricing
national tender rules
FFR variants have different frequency thresholds and activation times; use national tender conditions for bidding.
This is a representative value for the product family. The exact activation requirement depends on the contracted threshold and profile, so treat it as indicative rather than as one universal deadline
