Slide 6: Pilot project scope: 10 MW of interruptible load from industrial power consumers
Pilot project scope: 10 MW of interruptible load from industrial power consumers DR direction Demand curtailment. Term 1/1/2013 – 31/12/2013 Loads All are DGO-connected # of sites aggregated 15 Response time < 3 min Number of utilizations /year 25 Max. utilisation time / activation 120 min Cease tim
Slide 7: Two deviations from ELIA-ARP contract, validated by all involved ARPs
Two deviations from ELIA-ARP contract, validated by all involved ARPs, due to DSO- connected load Settlement: how REstore provides real-time metering signals at the level of the Aggregated Site to ELIA. One signal per 30 seconds shall be provided. to meter demand from Meters comply with the tech
Slide 8: Two types of demand curtailment: fixed Rref versus ICH / SL model
Two types of demand curtailment: “fixed Rref” - model (~ R3 production) versus the “ICH / SL” – model “Fixed Rref”-model: Rref always 100% delivered “ICH / Shedding Limit” - model MW MW Fixed Rref Shedding Limit Rref 100% delivered & guaranteed - always Rref not delivered. MW Comparable to turbine M
Slide 9: First learnings
First learnings Three activations so far, successfully and reliably delivered by aggregated DSO-load “Demand Side” delivers two different types of curtailment to ELIA, with strongly different value add: – R3 ICH with shedding limit: average availability – Fixed R(ref), available at any point in

Slide 11: Correction of BRP's perimeter (1)
Correction of BRP’s perimeter (1) Correcting the perimeter of the BRP during an activation with the requested energy is a powerful element as it incentivizes the BRP to effectively deploy this energy: Example 1: TSO requests 100MW – BRP activates 100MW Request : 100 MW Real activation : 100 MW Corre
Slide 12: Correction of BRP's perimeter (2)
Correction of BRP’s perimeter (2) Adjustment of the imbalance volume of the corresponding BRP is required in order to recover all activation costs for balancing purposes by the imbalance settlement Example 1: BRP 1 causes imbalance; BRP 2 is activated BRP 1 BRP 1 Initial Position: Position: -100MW -
Slide 13: Implications when BSP is not BRP (1)
Implications when BSP is not BRP (1) Elia investigated how to create a product that allows new players to bid energy as independently as possible from the ARP. Therefore the impact that an energy bid coming from a GU could have on the BRP and on the supplier was analysed. Request to GU : 40 MW Corre
Slide 14: Implications when BSP is not BRP (2)
Implications when BSP is not BRP (2) What if the GU activates less energy than requested (15 instead of 40)? Request to GU : 40 MW Correction BRP: -40 MW BRP 2 BRP 2 Initial Position: +100 – 100 = 0MW New Position: +100 - 85 -40 = -25 MW GU (Load) supplier Prod GU (Load) supplier Prod Buys Injection
Slide 15: Solutions aiming at independency of BSP towards BRP
? Solutions aiming at independency of BSP towards BRP: Solutions must keep main principles (1.a & b) but mitigate any damage to BRP nor Supplier (2 & 3) Correction of BRP’s perimeter (a. incentive for BRP Requested + b. covering of activation costs) 1 energy Discrepancy imbalance in BRP’s perimete

Slide 17: Main characteristics of most adequate model for DER (1)
Main characteristics of most adequate model for DER (1) 1. NO correction of BRPs perimeter: Request to GU : 40 MW No correction BRP 2 BRP 2 Initial Position: +100 – 100 = 0MW New Position: +100 - 60 -0 = +40 MW GU (Load) supplier Prod GU (Load) supplier Prod Buys Injection Buys Injection =100MW offt

Main characteristics of most adequate model for DER (2) 2. Capacity Only product: BRP 1 BRP 1 Zone is short: -100 MW Position: Initial Position: -100MW -100MW Request : 100 MW Imbalance settlement : -100 MW @MIP NO correction BRP 2 Initial Position: BRP 2 Zone is BRP 2 0MW NewPosition: balanced NewP
Slide 19: Feasibility for 2014 / 2015
Feasibility for 2014 / 2015 1. Contractual impact for Elia: 1. Balancing rules have to be adapted 2. “Contrat ARP” has to be adapted (contractual obligation for BRP to be balanced) » Obligation to be balances must remain » In real time deviations caused by activations should be authorized 2. Data ex
Slide 20: Data exchanges that are needed (1)
Data exchanges that are needed (1) 1. Settlement of the service (availability, activation): o Elia: verifies the availability of /activates a contractual reserved power o Aggregator: “splits” the reserve power into it’s pool of access points o DSO: owns the validated metering of the concerned access
Slide 21: Data exchanges that are needed (2)
Data exchanges that are needed (2) 3. How to Report each activation to the right BRP: o Elia: activates a amount of energy (cf; contractual reserved power) o Aggregator: “splits” the power into it’s pool of access points o DSO : owns the register of the supplier and BRP per access point o Contractua
Slide 22: R3 from distributed resources - feasibility for 2014 / 2015
R3 from distributed resources - feasibility for 2014 / 2015 (to be discussed within experts working group) 1. Contractual impact for Elia: 1. Balancing rules have to be adapted 2. “Contrat ARP” has to be adapted (contractual obligation for BRP to be balanced) » Obligation to be balances must remain
Slide 23: Tentative proposition for a R3 from distributed resources (1)
Tentative proposition for a R3 from distributed resources (1) 1. Needs: • Any new R3 product should have nearly the same ‘quality’ as R3 prod (availability, flexibility…) and at most competitive price • Remark: aggregators announce be competitive with R3 production 2. Volume: • Has to be limited in
Slide 24: Tentative proposition for a R3 from distributed resources (2)
Tentative proposition for a R3 from distributed resources (2) 4. Reservation • Need: 100% availability • Based on real metering and not on nominations • Controlled per quarter-hour • Reduction on R3 – Pmad ( Penalty on R3min-Pmad) • No control of availability during 2 hours after activation • Exampl
Slide 25: Tentative proposition for a R3 from distributed resources: Activation
Tentative proposition for a R3 from distributed resources 5. Activation • 1 activation = # quarters between start and stop • No remuneration necessary due to characteristics of Model • Based on real 15’ metering and not on 10” T.M. • Reference curve: based on last 15’ metering • Penalty per 15’ on (
