4 Forward contracts DIFFERENT ELECTRICITY CONTRACTING OPTIONS Forward physical/financial bilateral contracts Forward Energy auctions (Tariff customers and Virtual power plant) with physical/financial settlement of open positions Organized forward market with optional physical delivery in the day-ahead market Tariffs for customers, Tariffs for Special regime sellers, Etc. They are ALWAYS a price hedging mechanism with respect to the dayahead auction price. Day-ahead market is a physical regulated market, therefore there is always enough liquidity (except when there are real supply problems) Day-ahead market (IT IS NOT MANDATORY; it is possible to contract electricity outside the market at unknown prices) Optional integration of forward open positions Possibility of Day-ahead physical bilateral contracts Physical market Reference price. Compatible with the existing Production and selling utility sector structure in Spain and in the Iberian peninsula 4

5 MARKETS AND PROCESSES AFTER THE DAY- AHEAD ELECTRICITY MARKET Intraday market (auction based. 6 Sessions) Open to all agents, independently of the way in which they have contracted their energy at the day-ahead time (organized market or any kind of bilateral contract) The liquidity necessary to solve any adjustment problem at reasonable prices is concentrated in six auction sessions that are performed at predefined hours and with the same conditions for all agents. Technical management of the system. The correct design of the ancillary services and deviations markets is what makes viable the whole market design (day-ahead market and intraday markets) Apply only to the hours where there will not be an Intraday market session that applies to these hours (next 3-4 hours) Always exclusively related with system security Regulated in a way that allows the existence of an energy market with public prices achievable by all agents. No 5 arbitrage possibilities with other markets.

6 WHAT IS THE MEANING OF THE CONCEPT PHYSICAL ELECTRICITY MARKET? (I) Form the sellers side; At a given hour of the previous day (currently 10 a.m.) All physical electricity to be produced the next day need to have an owner. All options over physical production need to be exercised PRIOR to 10 a.m. of the previous day All production owners need to know what they are going to do the next day with their production, and they also need to declare their decision: Unavailable (S.O. verification and subject to Regulator inspection) Declare a bilateral contract (prior to 11 a.m.) Send a bid to the day-ahead market at free prices The DAY-AHEAD market is not a mandatory market, but it is a physical energy market where all physical available energy counts From the buyers side; Different options for obtaining their energy at the same hour. Regulation impeding abuse practices. 6

7 WHAT IS THE MEANING OF THE CONCEPT PHYSICAL ELECTRICITY MARKET? (II) Taking into account the structure of the production and selling utility sizes and organization in Spain and in the Iberian peninsula, it is the best option for: Correct day-ahead price formation, that is basic for all other forms of price hedging To provide the new investors with the necessary trust in the market organization It allows the Regulator the correct supervision of the market providing information that is possible to audit 7

8 SUMMARY The key elements from a competition point of view for the correct price formation and behavior of the electricity production market in the presence of producers of very different sizes are: Physical day-ahead market with no possibility of hiding any available production Single intra-day markets with all liquidity concentrated on them Security related processes organized in a way compatible with the existence of a market with no arbitrage possibilites with the market. 8

85 DEFAULT BIDS (II) - EXAMPLE A participant is bidding 200 blocks. So far he likes the price. In Round n (lower price) he wants to continue, but just supplying 150 blocks: In the default bid he sets a low price (lower to the actual round price) and sets the quantity to 150. In Round n+1 (lower price) he wants to supply 90 Blocks: In the default bid he sets a low price (lower to the actual round price) and sets the quantity to 90. In Round n+2 he would maintain the supply but with minimum price of 70 /MWh. In the default bid he sets 70 as price (higher to the actual round price) and maintains the quantity to 90.

99 MODIFICATIONS WITH RESPECT TO THE SIXTH AUCTION New Electronic Pre-qualification and qualification processes New facilities for sending, checking and updating the participant information during the prequalification and qualification process Possibility of checking, in a real time manner, the information received by OMEL from the Guaranties managers There will be an indicator meaning that a valid bid has been submitted for the round It will indicate that a valid normal bid exists for the round. Automatic bids and default bids will not be indicated. Possibility of printing some additional screens. Among them, the screen that shows the bids submitted. Electronically signing the bids can be simplified, at participant option (user configurable) New option to electronically sign new bids submitted, without requiring the PIN code each time. The PIN will be requested the first time a signature is sent, and each time the configurable PIN time-out period expires. The participant indicates in a local file the number of minutes (max 60) for the timeout PIN validity. Each time that a signature is sent, with the PIN or within the PIN timeout validity, the timeout period is renewed.

100 AUTOMATIC SIGNATURE The application can be configured to sign automatically for a period of time after the first signature (default is 0, maximum 60 minutes) Only after this time since the last signature (manual or automatic), PIN is requested again
