6 Our team provides valuable support along the value chain and across geographies Generating the best returns from our wind assets while at the same time reducing costs along the wind farm life-cycle to further increase the competitiveness of renewables is at the core of all our activities. We apply excellent technological and analytical skills to identify optimal sites and choose the best-suited technologies for our respective markets. Leveraging our experience from building industrialscale wind farms on- and offshore, we apply proven innovative technologies and installation methods such as our pioneering use of a scour technology in the construction process at Amrumbank West. We have built an impressive track record in renewables over the past years. Given our expertise and innovative approaches for wind and solar, we are committed to continue shaping the renewables industry going forward. Eckhardt Rümmler, CEO E.ON Climate & Renewables We recently completed Camster wind farm in Scotland which is located on land with a mixture of open peatland and commercial forestry plantation, which presented several challenges through the design and construction, mainly because of the depth of the peat. By using innovative construction techniques, we ve shown that ecologically sensitive land can be developed without damaging the environment. Geared towards our approach of cost-minimum delivery, we take advantage of large-scale procurement and work together closely with our suppliers to further improve components and construction approaches, and to reduce costs.

7 We carefully select wind farm sites and are committed to the sustainable implementation of wind energy When choosing our wind farm sites we rely on both our in-house expertise and independent environmental experts. We believe that a clear strategy and understanding of market trends and market specific factors, such as the local community and politics, is key to our success in development. Taking into account the impact on the environment, we manage to minimize the impact on the community and, where we can, make improvements to the area s landscape, environment and wildlife habitats. We are committed to the sustainable implementation of wind energy by actively supporting research As the renewable energy source with the biggest growth and share in the energy mix, wind energy is a key pillar of a cleaner energy future. Michael Lewis, Chief Operating Officer E.ON Climate & Renewables and development of suitable solutions to mitigate the impacts on ecosystems. We also work across the business and engage with our experts to choose the most suitable turbine and support along the whole value chain.

8 Our construction approach is based on high safety standards and aims at implementing high quality at low cost Health, Safety, Security & Environment (HSSE) is the first priority in any of our construction and operations projects. Any minor accident could cause major harm and medical help is often far away. Construction and maintenance work at our sites can be challenging and risky. Our employees on-site face tough environmental conditions in often extreme weather and work at great heights and in remote environments. We are committed to ensuring excellence in HSSE performance for all our employees, contractors and other stakeholders. Meeting this commitment is a primary objective and the individual and collective responsibility of all our employees. Wearing Personal Protective Equipment (PPE) for instance is a precondition for performing at our sites. Every routine is planned thoroughly to allow safe, fast and efficient execution. Raising the bar on our safety targets gives us the opportunity to set the standard for our industry. Our construction strategy We manage the project execution We design wind farms We procure materials We use local contractors Multi-lots strategy effectively fits all markets Best practice in place Priority to HSSE Capex reduction road map In-house construction rates benchmarks Lean concept for site works Deep logistics analysis Risk & critical path management We combine high quality and low cost Key success factors Extensive internal engineering capabilities of design to fit all location features Global knowledge of the wind energy market Aggressive schedule optimization Integration of renewables and non-renewables experiences (power, oil & gas) We deliver in time and on budget

9 We apply an active asset management approach to maximize the energy yield With our in-depth understanding of how wind farms operate and our high HSSE standards, we have created a culture of operational excellence and continuous improvement. We have developed a core competence in operating wind farms to remain at the forefront of the industry. We have established two dedicated Control Rooms one in Austin, Texas for our US fleet and one in Coventry in the UK for our European fleet to enable constant management of our wind farms. We regularly analyze our wind fleet to identify further performance improvement possibilities to maximize availability and production, and use predictive maintenance techniques to detect developing faults in advance of failure to avoid more costly interventions. We set ourselves demanding cost reduction targets to make wind energy ever more competitive and affordable. By focusing on the best projects, relying on our talent and pursing sustainable efficiency improvements, we target double-digit returns on our investments. Michael Kamsteeg, Chief Financial Officer E.ON Climate & Renewables By applying an active asset management approach, we optimize operation and maintenance efficiencies while maximizing the energy yield from operational wind assets. We manage all of our own sites and have positioned ourselves well to leverage our scale, experience and in-house technical competence to make E.ON the partner of choice in wind energy.

10 Our partnering models enable us to drive performance across the industry and offer customized solutions We partner up with stakeholders from across the industry and along the various stages of the wind farm life-cycle to further drive performance and offer customized solutions. We built London Array, the world s largest offshore wind park, in partnership with DONG Energy and Masdar. We are also a shareholder in Germany s first far-shore offshore project, alpha ventus. Based on our experience in managing large-scale projects and our technical and commercial excellence, we offer a suite of partnering and service solutions. We want to extend our cooperation with stakeholders across the industry and make E.ON the partner of choice in wind energy. Anja-Isabel Dotzenrath, Chief Commercial Development Officer E.ON Climate & Renewables Recently, we teamed up with DONG Energy and STRABAG to conduct an environmental investigation into the impact of offshore wind projects on the marine environment. The project will run for seven years in an area of up to 4,300 km 2 to the north of the East Frisian Islands. The joint investigation is expected to lead to a further reduction of environmental study costs by up to 50% as well as significantly lower emissions and other environmental impacts due to the bundling of activities.

11 In onshore wind, we develop new projects in close co-operation with large land owners like the Forestry Commission in Scotland, Statskog in Sweden and SCA in Norway. During the development phase we employ expert environmental consultants to provide the Environmental Impact Assessments as well as ecological services for our habitat management plans throughout the life of our wind projects. In doing this, the environment is substantially enhanced compared to the pre-wind farm state. When it comes to operations, we join forces with partners like GE to continuously optimize the performance of wind turbines. We also engage in customized ownership and fi nancing models. In our Build, Sell & Operate approach we take financial partners on board, who provide financing in return for steady cash flows, while E.ON manages and operates the asset throughout its lifetime. Our joint ownership of three onshore wind farms in the US together with pension fund PensionDanmark and the offshore wind farm Rødsand 2 in Denmark with institutional investors are excellent examples of generating value for our investors through development, construction and operations. We also offer partnering options prior to commercial operations (pre-cod) of wind farms to manufacturers, institutional and financial investors and recently entered into a partnership with GE for our Grandview Wind Farm in the US. Once completed, Grandview will generate enough electricity to power approximately 64,000 homes. We are always open to discuss potential co-operation with committed technical experts and financial investors alike.
