Generation Central power plants Offshore wind Onshore wind Hydro power Sales & Distribution Power distribution Gas distribution Gas storage E&P Focus area Energy Markets Purchase, sale and transport of power and gas Power and gas customers DONG Energy – an integrated Northern European energy company -with activities across the entire energy value chain ThermalRenewables The leading thermal generator on Nord Pool Leading position in power and natural gas infrastructure Denmark's largest seller of power and natural gas Growing sales across UK, NL and Germany Strong and growing equity gas position Expanding renewables portfolio Market leader in offshore wind 2

3. Strategy for transforming the production of power and heat in DONG Energy 2040 85 / 15 50 / 50 2020 1) 2006 total heat and power production 28,5 TWh eleq/ CO 2 - emissions 18,2 mt = 638 g CO 2 /kWh To provide reliable energy without CO 2 VISION STRATEGY Eliminate 50% of CO 2 -emission per kWh before 2020 Eliminate 85% of CO 2 -emission per kWh before 2040 3 2006 15 / 85 638 g CO 2 /kWh 1 320 g CO 2 /kWh 100 g CO 2 /kWh

4. Wind is key to the low carbon transition – and DONG Energy will continue to be a world leader OPTIMIZED PLANNING AND EXECUTION OF PIPELINE Strong in-house construction competence to secure portfolio synergies SIEMENS AGREEMENT 1800 MW supply agreement with steady supply OPTIMAL OFFSHORE INSTALLATION Acquisition of A2SEA world-leading installation vessels and crew STRONG POSITION THROUGH INDUSTRAILIZATION OF OFFSHORE Ploudalmezeau onshore Other Danish on- and offshore 1 Lake Ostrowo onshore Storrun 2009 onshore Nygårdsfjellet I onshore Nygårdsfjellet II 2011 onshore UNDER CONSTRUCTION (commissioning year) Barrow offshore Burbo offshore Horns Rev 2 2009, offshore Gunfleet Sands 1+ 2 2009, offshore London Array 2012, offshore Walney 1 + 2, 2011 & 2012, offshore IN OPERATION Karcino 2009, onshore Karnice 2009, onshore 4 Nysted offshore HR 1 offshore Capacity * MW In operation606 Under construction1.198 Project development1.990 *DONG Energy's share

6. The correlation between wind power-production, export and electricity prices  Today: Denmark exports a large share of produced wind energy – at low prices  DONG Energy's calculations: Additional 1000 MW wind power in western Denmark will produce 3,8 TWh – 3,2 TWh hereof will be exported The majority of the power needed for the electric cars can be sourced through reduced export. Our preliminary calculations show that 70% of the necessary power can be provided that way Wind Export Price Hours in in one year = 8,760 hours 6

7. The challenge of balancing production and consumption Consumption and wind energy production in West Denmark from 4-17 December 2006 Wind productionConsumption - - - Double wind production capacity 7

8. Energinet.dk: Computed power imbalance for Horns Reef 1 & 2 = 400 MW Fluctuation of -100/+175 MW in 15-20 minutes is possible That will require ~¼ power plant ramped up and down within 15 minutes Even across short time intervals the windpower production varies highly, creating a need for system balancing 8 Zero = production forecast

9. 9 Udfordring 2: Uintelligent ladning Normal-scenarie med opkobling ved hjemkomst efter arbejdstids ophør 00:0023:59 Vil med 200.000 biler i DONG Energy’s forsyningsområde i 2020 kræve en udbyging af distributionskapaciteten i lavspændingsnettet med 92 pct. Heraf vil ca. 50 pct. stamme fra elbiler Men den leverede energi til bilerne vil kun repræsentere en stigning på 6% 9

10. 10 Intelligent ladning Ladningstidspunktet flyttet til timer med lav efterspørgsel og tilhørende lave priser 00:0023:59 Intelligent ladning udnytter Overkapacit i elproduktionen Lav efterspørgsel fra andre forbrugsenheder 10

11. Consequently, the goals for DONG Energy are … 1. To secure a more value-creating demand for electricity 2. To make sure that most charging takes place at price low-points (typically between 22 and 05) 3. To make sure that EV-operators and their customers are reasonably incentivised to behave rationally 11

12. Which means do we have ?  Tarif structure  distribution tarif  fixed versus percentage based taxes on power  Metering infratructure  Implementation costs  Annual operational costs  Car registration tax exemption for EV's (or subsidy)  But what about PHEV's  And what about a gradual change of taxation policy towards congestions taxes 12

13. The Next Big Issue: Standardisation 1. Plugs 2. One or three phases – will determine charging time pr. kwh 3. Communication interfaces - choice will impact billing solution and business model options - must support integration with power supplier - can enable network interoperability 13

14. Roaming – a play on Metcalfe's law Metcalfe's law states that the value of a telecommunications networktelecommunications network is proportionalproportional to the squareto the square of the number of connected users of the system (n 2 ). First formulated in this form by George GilderGeorge Gilder in 1993, [1] and attributed to Robert Metcalfe [1]Robert Metcalfe in regard to Ethernet,Ethernet From Wikipedea: Implication is that if EV-owners belonging to one charging network can get access to power through another network a value gain is realised In other words, market fragmentation shall be avoided and roaming possibilities between networks ought to be promoted 14
