5. 5 Optimisation versus Trading Asset Optimiser Manages a portfolio of assets (power plants, contracts, retail portfolio,…) Objective is to control physical and financial risks and maximising margins = hedging Trader Creates a position Objective is to make money from this position when market conditions change = speculation Both actors sell and buy in the wholesale markets to achieve their objectives, thus creating a liquid market

6. 6 Timeline of activities of an asset optimiser From 3 years to 1 month ahead of implementation date [D] Forecast of the medium-term supply/demand balance Scheduling of power plant maintenance Sale/purchase operations on the forward markets 1 Month ahead of implemenation date [D] Refine the supply/demand balance to more accurate weather forecasts and availability of power plants Sale/purchase operations on the forward markets Day Ahead [D-1] Create operating schedule for the power plants Balancing supply and demand on the Day-Ahead market (DAM) Send nominations to TSO Intraday [D] Respond to latest unanticipated changes in the portfolio Send re- nominations to TSO Sale/purchase operations on the intraday market

12. 12 Interaction hedging - dispatching  DAH dispatch decision is independent from hedging decision in the forward markets Situation A Forward Market CSS = 5€/MWh Hedged Day-Ahead CSS = 10€/MWh PP dispatched Benefit 5€/MWh Situation B Forward Market CSS = 5€/MWh Hedged Day-Ahead CSS = 2€/MWh PP dispatched Benefit 5€/MWh Situation C Forward Market CSS = 5€/MWh Hedged Day-Ahead CSS = -3€/MWh PP not dispatched Benefit 8€/MWh Situation D Forward Market -3€/MWh Hedged Day-Ahead CSS = 3€/MWh PP dispatched Benefit 3€/MWh

13. 13 Capacity mix Europe

14. 14 CWE Market Coupling Launched on 9 November 2010 Cooperation of Transmission System Operators (TSOs) and power exchanges (PXs) coupling the Belgian, Dutch, French and German electricity markets Provides for the implicit cross-border capacity allocation and matching of orders of the involved PXs, resulting in the optimal allocation of available day ahead cross-border capacity and price convergence between day ahead wholesale electricity markets across this region

19. 19 Imbalance markets

20. 20 Levers for the TSO to manage the country balance primary reservesecondary reserve tertiary reserve via generation units tertiary reserve via sheddable customers uncontracted reserve ('free bids') reserve contracts with neighbouring system operators AUTOMATIC MANUAL 30sec <15min 15min

21. 21 Balancing: how does it work? Balancing = difference between production and consumption of the whole portfolio (metering) 1/4h Balancing obligation for each BRP Short position of BRP purchased at imbalance price - Long position of BRP sold at imbalance price + TSO takes care of the position of the country High incentive for BRP to be balanced Many opportunities for BRP Imbalance price is equal to marginal price activated by TSO Differences (extra incentive) only if big imbalances Imbalance price + and – are equal most of the time

22. 22 Imbalance prices NRV = Net Regulation Volume (=volume activated by Elia to restore the balance)POS = Positive Imbalance price (what you get paid if you inject more than you consume)NEG = Negative Imbalance price (what you pay if you consume more than what you inject) sunny day Cold evening peak
