3 DONG Energy Wind Power Core activities Development, construction and operation of offshore wind farms Market position Market leader in offshore wind, has built 38% of European capacity Strong pipeline of projects in lead-up to 2020 Business drivers Wind conditions Availability Electricity prices and subsidies Industrialisation and maturing of value chain Securing supplies via framework agreements and partnerships Partnerships with industrial and financial investors ROCE targets 2016: 6-8% 2020: 12-14% Strategic targets for 2020 Installed offshore wind capacity (before divestments): 6.5 GW Reducing offshore wind Cost of Energy to below EUR 100/MWh 3 1 The percentages indicate the proportion of the Group that each business unit represented in Intragroup revenue means that the business units combined revenue exceeds consolidated revenue. 3 Cost to society based on projects in the UK where investment decisions will be made in 2020.

4 DONG Energy has a significant portfolio and a strong pipeline of future offshore wind projects IN OPERATION UNDER CONSTRUCTION UNDER DEVELOPMENT Our offshore wind projects are centred around North western Europe UK, Germany and Denmark 4

7 Example of a Far Shore Site: Borkum Riffgrund Borkum Riffgrund I Offshore Wind Farm (BKR01) is situated approx. 40km north of the island Borkum Route partly in channel Speed limit Shallow water / tidal restrictions Long distance in open water 7 7

8 Breakdown of a Working Day for Technicians Technician working day when travelling from harbour in Norden-Norddeich to BKR01&02 Hours per activity, based on crew boats travelling with a speed of 17 knots Only approx. 6 hours with a traditional setup Working day Preparation Travel time WTG transfer Lunch break Acclimatisation Effective working time Consequences of long boat travel 8

17 Access from Large Vessels Ampelmann More than 390,000 transfers Long experience Oil & gas and offshore wind Typically 22m Heave compensation A-type typical 2.5m, E-type typ m Capability depends on vessel size Requires dedicated operators DP2 vessel required Source: 17

18 Access from Large Vessels OAS More than 190,000 transfers / more than 10,000 connections Oil & gas Typically 21m Typical connection time 5-30 min. (possible up to 60h) Operation in up to m Hs Capability depends on vessel size Can be operated by vessel crew after training DP2 vessel required Next Gen Unit under development 18 Source: + Lindsay Young, Man. Dir.

19 Access from Large Vessels Uptime More than 60 systems delivered Oil & gas (mainly) and offshore wind Typically 19.4m for large vessels Typically long connection times (days, weeks or months) Capability depends on vessel size Can be operated by vessel crew after training DP2 vessel required Has developed smaller version for CTVs Source: + Bjørnar Huse, Man.

21 Carbon Trust Offshore Wind Accelerator The Offshore Wind Accelerator (OWA) is Carbon Trust's flagship collaborative RD&D programme. Set up in 2008, the OWA is a joint industry project, involving nine offshore wind developers with 77% (36GW) of the UK's licensed capacity, that aims to reduce the cost of offshore wind by 10% by Source: Carbon Trust 21
