3 Many challenges ahead…how to mitigate ? 53 The significant increase in installed solar and wind generation capacity will have an impact on the system management as well as on the size and nature of the residual system imbalances, used as input for the dimensioning of the reserves, due to: -forecast errors -ramping

4 Overview of ELIA contracted reserves 2013description Primary Control (R1) or Frequency Containment Reserves (FCR) 91 MW Contain the system frequency after the occurrence of an incident or imbalance within the Synchronous Area. Secondary Control (R2) or automatically Frequency Restoration Reserves (FRRa) 140 MW Automatically activated reserves with an activation time less than 15 minutes which are used to restore the ACE of the control block to zero in case of an imbalance in the block. Manually activated reserves with an activation time less than 15 minutes which are used to desaturate the FRRa in case of large imbalances. Tertiairy Control (R3) or manually Frequency Restoration Reserves (FRRm) 661 MW : -400MW R3 production -261MW interruptible load 14/04/2015

5 Role of Balancing Responsible Party (BRP) 5 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 5

6 Mitigation 1: support balancing by BRPs 56 Residual balancing needs, to be solved in real-time by TSO, should be minimised. BRP responsibilities Invest in & use forecasting Be pro-active on markets (trade their imbalance, offer flexibility in DA & ID) Develop flexibility in their generation portfolios TSO responsibility Design appropriate incentives (imbalance) Develop liquid short-term markets in cooperation with PXs (NWE ID project) Provide publicly available forecasting and balancing data

8 14/04/2015 Mitigation 1: support balancing by BRPs

9 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. As isTo Be Contractual framework CIPU contract TBD Flexibility resources used for Ancillary Services Centralized Production Units covered by a CIPU contract Mainly TSO grid connected Centralized Production Units Decentralized Production Units & Load TSO & DSO grid Flexibility Supplier BRP producer Exception: GU for ICH Any BRP with physical flexibility BSP not BRP 9

10 Steps taken towards diversification… WhatInnovationDescription R1: “R1 Load” Production  load -Task Force organized with 3 GUs in 2011/2012 -30MW R1 UP provided by industrial load connected to Elia grid in 2013 R2: Diversification survey Centralized  Decentralized production Survey launched in October 2012 on Elia’s website in order to assess potential for R2 flexibility in Belgium, esp. from CHPs - CHP participating in 2013 to R2 R3: ICH 2013 Grid Users  Aggregators -Possibility to offer from a pool of load access-points connected to the Elia grid -15MW provided by BSP from a pool of 5 access points R3 (R&D) Pilot Project R3 from distributed load TSO-connected load  distributed load -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. March 4th 201310

11 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. 14/04/201511

12 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. 14/04/201512

16 1.No correction of BRPs perimeter 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 BRP 2 Initial Position: +100 injection – 100 load = 0MW GU (Load) Offtake = 100MW Prod Injection =100MW supplier Buys Sells BRP 2 New Position: +100 injection- 60 load - 0 correction = +40 MW GU (Load) Offtake = 100MW 60MW Prod Injection =100MW supplier Buys Sells Activation settlement: 40MW for BSP GU Imbalance settlement: + 40 MW @ MIP Example without activation Example with activation of 40 MW to GU & no correction “R3 Dynamic Profile”: product description 14/04/201516

17 2.Capacity Only product Activation settlement fur GU Imbalance settlement: +100 MW for BRP BRP 2 Initial Position: 0MW Elia Activation Request @ GU: -100 MW (load convention) NO correction BRP 1 Initial Position: -100MW Zone is short: -100 MW Zone is balanced BRP 1 Position: -100MW Imbalance settlement: -100 MW @MIP GU 100MW Prod 100MW BRP 2 New Position: +100MW GU 100MW 0MW Prod 100MW BRP 2 New Position: +100MW As there is no correction of BRP’s perimeter, activation costs are not covered by tariffs Activation costs have to be = 0 €/activation & entire remuneration provided on capacity fee  Number and duration of activations have to be contractually fixed Such product cannot be price maker  Volumes to be limited, at least initially BRP 1-100invoiced@MIP BRP 2+100paid@MIP GU+100Paid@Bid price Total+100Bid price Result: “R3 Dynamic Profile”: product description 14/04/201517

18 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  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; Trade off between conservative need and price 14/04/2015 “R3 Dynamic Profile”: product description 18

19 6.Availability control  Requirement of 100% availability;  Based on real metering (15’ metering) and not on nominations;  Controlled per quarter-hour;  No control during the activation  Penalty per quarter-hour based on Capacity Remuneration with penalty factor  With a yearly cap = yearly reservation remuneration Penalty for 1qh of missing power [€/qh] = 1,3 * Missing power [MW] * Capacity Remuneration [€/MW/h] * 1/4 Missing power [MW] = R3 [MW] – Pmad eq [MW]* Margin = Power that cannot be curtailed (vital elements of a site) Agg R3 Pmad P measured = M eq R3= Contracted MW that BSP must have available at any time Pmad = MW that BSP really has available “R3 Dynamic Profile”: product description 194/14/2015

20 Ref = Load equivalent off-take of last 15’min P(k) = Load equivalent off-take during activation R3 (k) = contracted volume (fixed amount; which might depend on PEAK/L-OFFPEAK-period ) Qh1 = quarter when the activation starts Reminder: No remuneration to BSP for the activation due to the model characteristics “R3 Dynamic Profile”: product description 20

21 7.Activation control start stop R3 Qh 1 Qh 2 Qh 3 Elia Request for activation  Limitation of 15 min metering data points Qh 0 Last Qh for activation serves as reference Qh (Ref) Energy that should be activated (incl. billable Margin) Ref P(k) = Really activated energy No availability control during activation “R3 Dynamic Profile”: product description 4/14/201521
