The lifecycle of a flexibility asset in mFRR and aFRR markets

Cleori manages the complete process as your Balancing Service Provider (BSP) and Aggregator, from asset registration through to settlement.

Pre-qualification & Registration

Assets must complete Elering's pre-qualification process to validate technical capabilities. We handle the entire process including:

  • Technical validation and testing
  • Balance responsibility arrangements
  • Data warehouse agreement setup
  • Integration with Balance Management Software

Registration typically takes 2-4 weeks depending on asset type and readiness.

Market Bidding

Cleori optimizes bidding across multiple markets:

  • Day-ahead: Bids submitted by 13:00 EET day before
  • Intraday: Continuous trading until 60 minutes before delivery
  • mFRR/aFRR: Gate closure 25 minutes before each MTU (Market Time Unit)

Our platform automatically determines optimal bid allocation based on market conditions and asset capabilities.

Activation

When Elering requires balancing services, we receive activation signals:

  • mFRR: Manual activation with 12.5 minute response time
  • aFRR: Automatic activation within 30 seconds

Your assets regularly poll the Activation endpoint and confirm when an activation is received. Cleori evaluates activation success based on the telemetry data reported during the event.

Settlement

After activation, we handle complete settlement:

  • Performance data submission to Elering
  • Verification of delivered flexibility
  • Invoice reconciliation

Initial estimates available within 24 hours, with final settlement typically completed within 30 days per Estonian market rules.
