Strategy for transforming the production of power and heat in DONG Energy / / ) 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 / g CO 2 /kWh g CO 2 /kWh 100 g CO 2 /kWh

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 , offshore Gunfleet Sands , 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

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

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

Energinet.dk: Computed power imbalance for Horns Reef 1 & 2 = 400 MW Fluctuation of -100/+175 MW in 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 Udfordring 2: Uintelligent ladning Normal-scenarie med opkobling ved hjemkomst efter arbejdstids ophør 00:0023:59 Vil med 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 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

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

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

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

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
