Slide 3: Product Design principles SDR from DSO-grid
Product Design principles SDR from DSO-grid Key questions: As explained in previous sessions (Experts WG & TFiSR): o design questions related to SDR will mainly be discussed in TF iSR o in order to reduce complexity Elia aims at keeping differences between SDR-DSO and SDR-TSO to a minimum. Ex: sam
Slide 4: Product Design principles SDR from DSO-grid: Shedding modalities
Product Design principles SDR from DSO-grid Shedding modalities: During Last task Force Elia proposed to make SDR evolve from “DROP TO” also to “DROP BY” and offer the possibility to SDR candidates to choose between two options: DROP TO a fixed Shedding Limit DROP BY a fixed Power (deltaP) Target
Slide 5: Product Design principles SDR from DSO-grid: Impact on BRPs perimeter
Product Design principles SDR from DSO-grid Impact on BRPs perimeter in case of activation: When using flexibility provided by decentralized resources and parties that are not BRP, the impact on supplier and BRP have to be handled: Several models have been discussed for a few years within Elia a
Slide 6: Submetering
Submetering Improves accuracy of determination activated flexibility service/volume Provides extra liquidity by allowing diversification in offered flexibility services at 1 customer site Expert WG 14/10/2014 Rapport Forbeg dd. 3/2/2014 Use: subject to product design, Important principles :

Slide 8: Sub-meter
Sub-meter DSO understands the potential need of sub-meter When a sub-meter is needed for the market processes, the DSO (as neutral party) must Place, collect and validate sub-metering data Calculate flexibility data : cf. base-lining Facilitate the Settlement: sum of flexibility data per E
Slide 9: Content
Content 1. What is a baseline and for which purpose will it be used for ? 2. Many baseline methods 3. What‘s the best baseline ? 4. Baseline process - Roles & Responsabilities (to define) 5. Proposal of planning and next steps Expert Working Group – 1711/2014 9
Slide 10: What is a baseline and why is it needed?
What is a baseline and why is it needed ? • A baseline is an estimate of the electricity that would have been consumed/produced by a customer in the absence of a demand response event. Event duration effectively activated energy volume Consumption P [kW] Fixed shedding limit 1/4h • Control of activa
Slide 11: What baseline(s)?
What baseline(s) ? • Not necessary to “reinvent the wheel” : several baseline methods exist already ! • Methods based on historical measured data: averaging methods (X of Y), regression methods, meter before/after, … with or without adjustements • Already used baselines: - R3DP : static baseline sha
Slide 12: What's the best baseline?
What’s the best baseline ? Fundamentals • Getting everyone to agree on one (or several) baseline(s) • Must be in line with the goals and interests of all stakeholders Acceptance • Estimation of the effectively activated energy Accuracy volume within a (statistical) confidence interval Precision • Fi
Slide 13: Baseline process
Baseline process General principles (proposal) Starting phase Validation Activation Verification phase control phase • No or limited experience learning process • Consultation process • Publication of validated baseline methodologie(s) Expert Working Group – 1711/2014 13
Slide 14: Baseline process: Roles & Responsibilities
Baseline process Roles & Responsibilities to define … Starting phase Planning ? • Baseline methods proposed by aggregators ? • One or several methodologies ? • Baseline / EAN • Need to validate ? Activation control Verification phase • Part of the functioning rules • Part of the contract When ? Why

Slide 17: Baseline design principles
Baseline design principles = Accuracy >» Providers should receive credit for no more and no less than the curtailment/ enhancement volumes they actually provide = Integrity >» A program should not encourage irregular consumption and irregular consumption should not influence baseline calculations; i
Slide 18: Baseline best practices
Baseline best practices* = Customer specific baseline rather than a portfolio baseline [simplicity and aligment] = Use Y days as baseline window [accuracy and integrity] = Select X days, where X is less than Y to exclude days with lowest load [accuracy] = Applying high X of Y exclusion rules among “
Slide 19: Proposed baseline based on principles and best practice
Proposed baseline — based on principles and best practice = Where it increases accuracy at a reasonable cost, the baseline should be based on the sub metering data " To strike the best balance between simplicity and accuracy, the baseline should be based on > 4of5 of the last weekdays if the event i
Slide 20: Baseline methodology choice: Behind the meter generation
Baseline methodology choice: Behind the meter generation = Emergency gensets > Donotrun on a regular basis (as opposed to CHP) >» Baseline should be 0, i.e. all energy produced by genset during an event should be counted as activated energy > Implicitly covered by general baseline methodology using
Slide 21: Baseline methodology choice: Who does what?
Baseline methodology choice: Who does what? Vv VvVVWV WwW VvVVV YW > > Role of the aggregator (BSP) Receives head-metering from DGO or TGO Receives sub-metering from sub-metering provider (consumer or other) Calculates baseline based on approved methodology Calculates activated energy based on diffe
Slide 22: Baseline methodology choice: Other considerations
Baseline methodology choice: Other considerations = Only one baseline therefore no need to choose baseline based on DR type = Accuracy of chosen baseline methodology can be evaluated in the specific Belgian context by the TGO and adapted if needed for SDR 2016-17 > Based on sub-metering data provide

Slide 29: Pre-qualification: Update of C8-01
Pre-qualification Update of C8-01 : Limitation to NFS process Independent of the ELIA product (for instance R3DP & SDR) Timing must be in line with tendering ELIA SDR 2015/2016 EG ELIA 17/11/2014 29

R3DP 2016 Expert WG 14/10: stakeholders call for stability, i.e. prolongation of existing R3DP 2015 product design while maintaining 100MW (?) volume cap. However, stakeholders require … transparent and non-discriminatory rules for “partial activation” @TF Balancing submetering @TF Balancing
Slide 32: STS R3DP
STS R3DP Link to SDR: transition to STS as from 1/1/2016 also favors load to participate to SDR tendering and monthly to R3DP for those months outside of SDR period (Apr – Oct) Bidladder ? ELIA will implement ELIA is committed to ELIA will focus on STS of R3DP and investigate Bidladder open to i
