mFRR – Procurement
11
– German TSOs jointly dimension and procure mFRR (and aFRR)
– Indicative reserve amounts: aFRR ≈ 2.2 GW, mFRR ≈ 2.5 GW
– Fully harmonised requirements and market frameworks
Dimensioning and
Procurement
– are submitted day-ahead for 4h validity blocks (e.g. 4:00 – 8:00)
– consist of a capacity price and a energy price
– have minimum size of 5 MW (increment 1 MW)
– may be indivisible (as long as ≤ 25 MW)
Bids for mFRR
– mFRR capacity - daily auction (at 10:00) for all German TSOs –
the bids with the cheapest capacity price are selected
– mFRR activation - selection of the cheapest energy prices among
the bids accepted in the auction
Bid Selection
![Page 12: Electricity Balancing Pilot Project 1 Imbalance Netting](https://reader031.vdocuments.net/reader031/viewer/2022020700/61f4b42bb083f74f004c82db/html5/thumbnails/12.jpg)
mFRR – Main Technical Requirements
12
– Pooling of single units located in one LFC Area is allowed
– One provider can operate more than one mFRR pool
– The providers have to provide information on planned “location” of
capacity
Pooling
– Capability to fully activate or deactivate the bid capacity
within 15 min at any time (within the validity period of the bid)
– Capability to deliver the full bid capacity during the whole validity
period of the bid
Full Activation
Time and Delivery
– mFRR activation can be triggered immediately (UCTE
terminology - “direct tertiary control”) or for specific quarters of
an hour (usual case), regardless of that,
– the activation request and settlement are based on schedules
Activation and
Settlement

Communication of Activation Requests
18
– TSO enters the required power
– The MOLS determines the cheapest bids under consideration of
availability and congestions and …
– … sends the activation orders and schedules
Process
– The communication between MOLS and the mFRR provider is
implemented via Activation Files (XML) which are digitally
signed, compressed and encrypted
– The SSH-FTP protocol enables proof that a file was stored
