Slide 37: Why considering a switch to central gateway?
Why considering a switch to central gateway? – The Local Gateway has been mentioned as one of the key barriers to the development of LV flexibility as the associated cost for the gateway installation and operation entirely kills the business case – For this reason, Elia and the DSOs temporarily allo

High volume of real-time data as an additional barrier? – Some market actors reported that Elia’s requirements were rather stringent imposing high volumes of data to be sent in real- time at individual asset level. Further analysis reveals that this element is highly dependent on the different commu

aFRR & mFRR capacity auction design evolutions Kris Poncelet
Slide 55: Assessment possible future revision of the aFRR capacity auction
Recall WG of 6th Feb 2025 Assessment possible future revision of the aFRR capacity auction • Elia intends to assess the need for possible future revisions of the auction for aFRR capacity. • The main motivation for the evaluation is the increasing liquidity in the aFRR capacity auctions and more par
Slide 56: Increase in awarded Single-CCTU volumes
Recall WG of 4th April 2025 The increase of liquidity in the Single-CCTU product led to an increase in awarded Single-CCTU volumes… Throughout 2024, the share of volumes awarded from the All-CCTU product remained rather stable Significant ALL-CCTU share in the upward direction. Highly limited
Slide 57: Significantly lower capacity prices/costs start 2025
Recall WG of 4th April 2025 … which result in significantly lower capacity prices/costs start 2025 While aFRR capacity prices (and costs) slightly increased in 2024 (relative to 2023), a significant decrease in aFRR capacity prices and costs is observed early 2025 due to more and more competitive Si
Slide 58: In the meantime
In the meantime • Elia engaged in bilateral discussions with many BSPs • The liquidity in the aFRR Capacity auctions (and in particular in the Single-CCTU product) has stabilized. • CREG requested in Decision (B)3047 to perform an amendment of the aFRR capacity auction design such that more than the
Slide 59: Objective of today's presentation
Objective of today’s presentation • Present the assessment performed by Elia • Present main feedback received from stakeholders in bilateral discussions • Present Elia’s resulting proposal for evolutions of the capacity auction design
Slide 60: Scope of the assessment
Scope of the assessment Considering the input provided by BSPs and CREG, Elia has performed an assessment on following aspects: • Increase procured aFRR capacity when economically justified: • Can more aFRR capacity be procured in moments the marginal price for aFRR capacity is below the marginal pr
Slide 61: Procurement cost reduction
Increase procured aFRR capacity when economically justified (1/1) 140.000 Procurement cost reduction • Context: For some CCTUs, the marginal price for upward aFRR capacity has 120.000 been observed to be below the marginal price for upward mFRR capacity. 100.000 80.000 [k€] 60.000 40.000 • In these
Slide 62: Increase procured aFRR capacity when economically justified (2/2)
Increase procured aFRR capacity when economically justified (2/2) • The potential benefits could be captured through a joint aFRR and mFRR capacity auction, which could look as follows: • Objective function: minimize aFRR + mFRR procurement costs* • Constraints: • Volume of aFRR procured ≥ aFRR Need
Slide 63: Deviation from total cost minimization
Deviation from total cost minimization • In the current aFRR auction, there is a mechanism to deviate from the minimal cost solution by “favoring” the selection of single-CCTU bids. This mechanism was successful in fostering the development of liquidity in the single-CCTU market segment. This mechan
Slide 64: Relevance of maintaining the All-CCTU product (1/3)
Relevance of maintaining the All-CCTU product (1/3) • The All-CCTU product differs from the Single-CCTU product in the following ways: • All-CCTU bids span an entire day • All-CCTU bids are mutually exclusive (i.e., only one All-CCTU bid per BSP can be selected) • All-CCTU bids are indivisible • The
Slide 65: Relevance of maintaining the All-CCTU product (2/3)
Relevance of maintaining the All-CCTU product (2/3) • Considering the current levels of liquidity in the Single-CCTU aFRR product, the removal of the All-CCTU aFRR capacity product at this moment would hence come with the following risks: • Risk of increasing aFRR procurement costs • Risk of periods
Slide 66: Relevance of maintaining the All-CCTU product (3/3)
Relevance of maintaining the All-CCTU product (3/3) • Illustration of a joint aFRR/mFRR capacity auction with Single-CCTU aFRR Bids, All-CCTU aFRR Bids and Single-CCTU mFRR bids: • Objective function: minimize aFRR + mFRR procurement costs* • Constraints: #𝑆𝑖𝑛𝑔𝑙𝑒−𝐶𝐶𝑇𝑈 𝑎𝐹𝑅𝑅 𝑈𝑝…
Slide 67: CCTU granularity (1/2)
CCTU granularity (1/2) • Currently, Elia procures aFRR and mFRR capacity in blocks (CCTUs) of 4 hours each • Procuring capacity in 4-hour blocks might not be suitable for all technologies due to: • Non-constant availabilities during the 4-hour period (cf. illustration PV) • Non-constant (opportunity
Slide 68: CCTU granularity (2/2)
CCTU granularity (2/2) • A benchmark with other countries reveals some other countries already have more granular CCTUs: • France and the Nordic countries have hourly aFRR and mFRR Capacity products • Spain has quarter-hourly capacity products • Germany and Austria have 4-hour capacity products but
Slide 69: Bid complexity Single-CCTU product
Bid complexity Single-CCTU product • Single-CCTU aFRR and mFRR Capacity Bids are currently fully divisible and no linking of bids is possible (e.g., block bids, exclusive groups of bids) • A benchmark reveals different practices in different countries: • No bid complexities in the German-Austrian ca
Slide 70: Paid-as-bid remuneration for aFRR and mFRR Capacity
Paid-as-bid remuneration for aFRR and mFRR Capacity • aFRR and mFRR Capacity is currently remunerated based on a paid-as-bid scheme. Benefits paid-as-cleared remuneration Drawbacks paid-as-cleared remuneration • Efficient allocation of capacity reservation • Prone to market power and abuse • Reduced
Slide 71: Overview of proposed evolutions
Overview of proposed evolutions Proposed evolutions • Evolve to a joint auction for aFRR and mFRR (minimizing costs to secure the required aFRR and FRR) ❑ Decrease capacity costs ❑ Increase depth and attractiveness of the aFRR capacity market ❑ Secure additional aFRR Energy Bids ❑ Simplify the aFRR
Slide 72: Next steps
Next steps • Elia welcomes additional feedback on the proposed aFRR and mFRR capacity auction evolutions • Please contact your KAM Energy • Implementation possibilities and timeline will be further investigated by Elia • Key feedback (and implementation planning) will be presented in the WG BD&S o

Slide 74: The mitigation measure aimed at avoiding ENTSO-E's penalty
The mitigation measure aimed at avoiding ENTSO-E’s penalty Context: Trigger for Elia’s initiative: - Discussions at ENTSO-E level to penalize TSOs contributing too much for DfD. In 2022 Elia exceeded the 30% threshold of DFD contribution for 3 quarters. - The potential penalty is an obligation to co

Slide 76: Next steps
Next steps Elia’s contribution to DFDs is constantly decreasing and external factors should manly confirm the trend in the near future.
