Conference 11 February in Reykjavik: Power exchange for electricity Opportunities or constraints?

1. Conference 11 February in Reykjavik:Power exchange for electricityOpportunities or constraints? Is the Icelandic market ready for new challenges? Rickard Nilsson Project Manager Nord Pool Spot AS E-mail: rn@npspot.com Tel: +46 (0)8 555 166 06

2. Agenda • Reflections on market design, regulations, opportunities and challenges with establishing spot trading • In reality how different are Icelandic fundamentals from elsewhere when spot market places were started? • Some trading and market design issues "open for debate” that are important to get feed-back on from potential market parties and also other stakeholders • Brief facts and features in Elbas, the system intended for the "Isbas" Market for spot trading 

3. Were framework conditions and rules perfect elsewhere when spot markets were launched? • Norway-Sweden 1996? Examples: • Limited cross-border capacity for market due to historical bilateral priority contracts lasting until about 1999 • Only hourly bids in spot although Swedish needs for blocks • Many retailers and end-consumers had pre-deregulation supply contracts that lasted several years thereafter, thus free choice and competition was not really there from start • Switch of supplier was costly in Sweden because until ”profile ontracts” were introduced in 1999 customers has to buy metering device to switch supplier • No common adjustment (intra-day) market and only weak co-ordination of RPM, i.e. real-time (TSO) balancing market • Nor-Swe-Finland 1998 plus Denmark 1999-2000? Examples: • Tariffs imposed Swe-Fin and Swe-Den in the first few years • Almost no market access to capacity Norway-Jutland since pre-deregulation bilateral contracts not abandoned from start, also limited capacity Swe-Fin and Swe-Den in the beginning and for similar reasons • No common intra-day trading and still weak co-ordination of RPM on Nordic basis, which however came about very clearly in autumn of 2002 • Only large scale consumers (ex. >10 GWh) in Denmark had access to market and could shift supplier in first few years with the spot market in Denmark Basically all the constraints above have since long been eliminated, but the point is that the market could function and develop even with those imperfections! In other words, even with imperfect conditions a promising development can be achieved as long as most parties, including stakeholders with powers to set rules, strive for improvements and seek opportunities with open and transparent trade!

4. Positives in Icelandic marketSome general ”early observations from a foreigner who has seen and been part of a few spot market start-ups before” • Strong focus on power system fundamentals, combined with recognition of economic realities and opportunities • Balance Responsible Agreement in place between TSO and ”suppliers” that enables trading, and can be developed further • Some inherent flexibility in production and consumption • Significant growth of (industrial) demand ”likely” and ample opportunity to increase hydro and geothermal power production • Finally, a ”negative” that can be a positive – namely that it seems like quicker and more transparent signals of surplus and scarsity situations in the power system is needed, and that is precisely what an organized spot market can facilitate!

5. Design questions for the ”Isbas” Market Examples: • Opening hours for trading • Closing time for contracts • Settlement cycle • Clearing requirements • Market place functions – who and what • Currency for trading • Minimum trading lot (volume) • Minimum price step in bid/ask quotation • Needed content in Rulebook • Liquidity facilitation • Use of ”market makers” • Other issues?

6. Outlook - immediate future • A Power exchange for spot tradingcan be • Ready for launch in September 2008 • Operated by Landsnet or a contractor of their choice • Technically supported by Nord Pool Spot (trading system, etc.) • Based on continuous trading as in NPS’ Elbas Market • Trading Area of the Icelandic market • The Icelandic market will be a separate/independent trading area • Reasons for proposal • Market players in Iceland have little experience in exchange trading • The Icelandic market is fairly small and a limited number of actors exist, at least initially • Continuous trading preferable in the beginning, because it is not as vulnerable towards lack of liquidity as auctions • Trading today in Iceland is based on bilateral contracts • Further developments, i.e. day-ahead spot auction and long-term (financial) contracts may be developed later, if it suits the market

7. Elbas market at Nord Pool Spot today • Adjustment market after Elspot • Trading intra-day and after Elspot is closed (confirmed) also day-ahead • Market areas:Finland, Sweden, East and West Denmark and Germany (KONTEK) • Continuous trading • Open around the clock all days of a year • Hourly contracts can be traded until one hour before delivery hour • Trading is anonymous • Trading currency is Euro • Settlement and clearing is combined with the Elspot Market at NPS • Common Rulebook with Elspot (separate details in appendices/agreements) • Automated control of grid capacity • Communication in public network with SSL-encryption • Market makers 24 hours per day • Number of customers: 55

8. Why do companies trade on the Elbas market?Many arguments can also be valid in Iceland An effective and economical way to manage electricity procurement and sales near the time of delivery To sell production, cover consumption or trade single hours today & tomorrow Handling of unexpected changes in electricity production, procurement or consumption in your electricity balance React to unexpected changes in the market price and need for power -> You can hedge the price you have to pay for imbalances -> You can reduce the volume exposed for imbalances -> You can increase the efficiency of daily management of your electricity portfolio Not dependent on one volume, price or counterpart Increases transparency of day-ahead and intraday prices Trading made easy and fast: Web based trading system The market is ALWAYS open Market making 24 hours per day Automated and simple functionalities Automatic clearing, netting of collaterals, and one settlement account for Elbas* Note: *At NPS the Elbas settlement/collaterals is combined with day-ahead Elspot Market

9. Nord Pool Group Markets • Physical market – Elspot– Nord Pool Spot AS • trading in energy – day ahead (hourly contracts) • Swe, Fin, Den, Nor and VE-T area in Ger* • Adjustment market – Elbas– Nord Pool Spot AS • trading in energy – intra day (hourly contracts) • Financial market– Nord Pool ASA • financial power contracts** up to 5 calendar years ahead • EUA (CO2-allowances ) and CER • Clearing of financial contracts, incl. OTC– Nord Pool Clearing ASA Notes: * Plan is to in June 2008 establish ”Market Coupling” with EEX spot between Den and Ger **Until 2007 Nordic contracts based on Elspot (System) Prices as underlying, but from early 2008 also contracts based on Dutch (APX) and German (EEX) spot prices

10. The Elbas timeline 14:00 in SE, FI and DK2 Next days delivery hours opened at: Delivery hour ELBAS C o n t i n u o u s t r a d i n g until 1 hour before delivery ELSPOT TSO:s real time market • At 14:00 in SE, FI & DK2 the hour series for the next day are opened (the hours 01-24) • At 08:00 in GER and at 17:00 in DK1

11. An idea for ”Isbas” timeline & structure Note: The point is merely to illustrate how it could function Opening hours for trading 09:00 15:00 Delivery hour C o n t i n u o u s t r a d i n g until 2 hours before delivery "ISBAS" Landsnet’s real time market Hour 13 (time 12-13) is nearest hour possible to trade when market opens • At 09:00 the market opens for trading hours 13-24 today plus hours 1-24 tomorrow. Thus for 36 separate hourly contracts. • At 10:00 trade for hour 13 is closed and at 10:05 the Isbas system sends a report with final net trade per Balance Responsible for hour 13 to Landsnet. Every hour shift the procedure is repeated until 15:00 when a final net trade report is sent for hour 18, and for hours 19-24 plus hours 1-12 tomorrow. • Settlement for “today’s hours” then occurs tomorrow if daily settlement cycle is applied or the 1st bank day the following week if weekly settlement.
