Role of Balancing Responsible Party (BRP)
•
•
•
•
•
•
Balancing responsible parties (BRPs) are responsible for balancing their
perimeter on a 15-minute time interval in the Belgian system.
BRPs have to nominate a balanced perimeter in day-ahead and have to
perform intraday adjustments according to more accurate intraday
forecasts and actual measurements of production and off-take, as the
uncertainty on the final balancing position of the perimeter decreases
towards real-time.
Any residual system imbalance is in last instance resolved by Elia by
deploying the reserves at its disposition.
As a result, any assessment of the required reserve volumes crucially
depends on the behaviour of BRPs
Once all metering is known, ELIA calculates imbalances per Qh per BRP
Imbalances are invoiced at imbalance tariffs:
MDP= Marginal Decremental
Price = Lowest downwards
activation price
MIP = Marginal Incremental
Price = Highest Upwards
activation price

Mitigation 1: support balancing by BRPs
Residual balancing needs, to be solved in
real-time by TSO, should be minimised.

Mitigation 1: support balancing by BRPs

Mitigation 2: facilitate diversification
Purpose: opening the Balancing Energy & Reserves Market to a new kind of flexibility.
Today :
Majority of Balancing Energy & Reserves provided exclusively:
- By injection ARPs (who have signed a CIPU contract)
- On Centralized Production Units
- Exceptions: Interruptible Load and R1 Load from ELIA-Grid Users
Goal:
Extend participation of Balancing Energy & Reserves to new resources (load and
decentralized production units) and new players.

Pilot Project
R3 from
distributed
load
Description
- 10 MW of interruptible load on the distribution grid
- Concrete case study that allows to:
-test the technical performance of interruptible load in
distribution grid
-gain experience on control modalities and contractual
prerequisites
- Based on above pilot project, ELIA developed for 2014
a new product “R3 Dynamic Profile” to contract
flexibility, principally situated at distribution grids, to
complement its existing R3 portfolio.
Continuous stakeholder consultation
 Against this fast-changing context, ELIA established the Balancing Taskforce
(as ad hoc group under Users’ Group) as the platform via which Elia consults
the market when proposing evolutions to balancing and ancillary service
mechanisms.
 During such Taskforce of Jan 11th 2013, dedicated to the contractual models for
diversification, it became clear that there are quite some complex issues to be
tackled in this respect. Those issues are emphasized for resources located in
distribution grid as Elia does not own any metering in those grids. It’s for this
specific purpose that an “Expert Working Group” (as subgroup of TF Balancing)
has been created, consisting of BSPs, BRPs, DSOs, FORBEG and ELIA.

Main questions to be discussed within the working group:
- How to manage the impact on the BRP of the activations by a BSP non-BRP:
- How the manage the control and remuneration of ancillary services provided
from resources that are not directly metered by Elia.
- Balancing services provided by resources located on distribution grid, should not
cause congestion problems on distribution grids  importance of
establishing a prequalification process with DSOs to assess and qualify eligible
access points.

The development of R3 Dynamic Profile
 Conclusions of this working group will directly be reported to the Task Force
Balancing. Elia will finalize its proposals taking into account the input of the
Taskforce and will then require appropriate approval from CREG.
 Experts has met 4 times now with focus on establishing the R3 Dynamic Profile
product for 2014 using flexibility residing at distribution access points (short
term) and providing recommendations for the long term.
 In order to achieve this first step, Elia introduced on April 17th, according to
article 233 of the Federal Grid Code, a proposal to the CREG for the applicable
reserve volumes for 2014 with a specific part related to the procurement of
reserves through a ”R3 Dynamic Profile” product.
 Having no experience with the performance of such a product, Elia decided to
limit the volume of ”R3 Dynamic Profile” to be procured at 50 MW maximum
for 2014.
 After technical qualification performed by DSOs and Elia, Elia will apply a
market based approach to contract between 0 to 50 MW with the “R3 Dynamic
Profile” product.

“R3
Dynamic Profile”: product description
1. No correction of ARP-perimeter
• Amendment of ARP-contract, introducing notion of “Dynamic Profile Provider”, incl. information to ARP
when activating
2. Capacity only product
(no activation price nor payment to BSP)
3. Needs
•
To open R3 to Distributed Energy Resources (load and prod with AMR Meter) through BSP
participation; resources at TSO level could also be eligible to be part of the BSP pool for this product;
4. Volume and selection
•
Limited volume in comparison with R3 production due to the model characteristics (i.e. end of the merit
order, tariffs impact) and to gain experience. Start with max 50 MW
5. Number and duration of activations
 Around 40 activations; Maximum duration of 2 hours;
6. Availability control
 Requirement of 100% availability (cf R3 Production); Controlled per quarter-hour;
 Based on real metering (15’ metering) provided by DSO (and not on nominations);
7. Activation control

1 activation = number of quarters between start and stop of Elia-bid
Based on real 15’ metering and not on 10” T.M.
Reference curve: based on the last 15’ metering
Settlement in balancing prices : as R3 Dynamic Profile is only activated in merit order after R3
Production is activated, the MIP will reflect the most expensive R3 free Bid price

Only upward activation in “all or nothing modus” (complete contracted volume is activated);
BRPs position is raised with the effectively activated energy
 BRP (and through him Supplier) is remunerated by the tariffs;
 BRP is not penalized for the discrepancy;
A specific control of the activation is necessary as there is no incentivizing correction
In principle the final position of the BRP is favourable towards the position of the zone
The effect will be moderate due to characteristics of the product:
 Limited activation duration
 Limited # of activations => after R3 production in merit order

3. Needs
•
•
•
•
To open R3 to Distributed Energy Resources (load and prod with AMR Meter) through BSP
participation;
Resources at TSO level could also be eligible to be part of the BSP pool for this product;
To have nearly the same “quality” as R3 prod and at competitive price;
To be able to launch a Tender for this product in 2013, in parallel with ICH;
4. Volume and selection
•
Limited volume in comparison with R3 prod due to the model characteristics (i.e. end of the merit
order, tariffs impact) and to gain experience.
 Start with max 50 MW
 Minimum threshold for participation: 5MW P/OP/BASE offer (for other selection rules, see annexe)
 Candidate BSPs must provide their margin for P/OP/BASE per EAN of their pool
5. Number and duration of activations
•
•
•
•
Both contractually predefined and will influence the reservation price
Number as close possible as number of R3 prod activations but can be less, as activated at the end of
merit order
 Around 40 activations
Trade off between conservative need and price
 12h between 2 consecutive activations
Duration of activation must be limited to avoid a change of NRV sign during activation
On the other hand a duration of activation must fulfil to current R3 prod characteristics and needs of
dispatcher
 Maximum duration of 2 hours;
