Wind power: By the end of 2010 we had generation capacity of 3.6 GW (about ten times the amount we had three years ago). The major share comes from onshore wind power. In 2010 we commissioned over 350 MW of onshore wind power, including the wind parks Papalotte Creek 2 in the USA with 200 MW, Wielkopolska in Poland with 52.5 MW and Barao Sao Joao in Portugal with 50 MW. In the area of offshore wind power, we have a capacity of 467 MW. In 2010, E.ON installed around 40 percent of all offshore wind power generating capacity installed in Europe. We completed wind farms at Robin Rigg (180 MW) off the UK's northwest coast, Rödsand II (207 MW) in the Baltic sea off Denmark and alpha ventus (60 MW) in the German North Sea. Further wind farms with a total capacity of 3 GW are under development or construction; these include London Array, a cooperation project with Dong Energy and Masdar. The first construction phase with a capacity of 630 MW will be connected to the grid in 2012. After completion of the second phase, London Array will have a capacity of 1 GW.


Hydroelectricity: We have over 4.8 GW of hydroelectric capacity from river and pumped-storage power plants. In 2010, E.ON worked mainly on the construction and expansion of pumped-storage plants, for instance in Waldeck and in south-east Bavaria, which help amongst other things to balance out fluctuating generation from renewables.


Biomass: Since 2008, we have run a 44 MW wood-fired power station at the Steven's Croft site in Lockerbie, Scotland. The plant is one of the largest pure-biomass power stations in the UK and represents a saving of 140,000 tons of CO₂ every year compared to conventional generation. Other biomass projects with a total capacity of 400 MW are in various stages of development.

Natural gas: Power plants with combined cycle gas turbine technology (CCGT) achieve high thermal efficiencies and therefore only emit comparatively small amounts of CO₂. Through combining heat and power generation (CHP) even higher efficiency levels can be achieved. In 2010, we brought one of the most efficient and powerful CCGT plants in the world onstream in Irsching, upper Bavaria, with an efficiency factor of nearly 60 percent. With the highly efficicent gas-fired generating unit Irsching 4 planned for 2011, we will have achieved a total efficiency factor of over 60 percent for the first time ever. Further CCGT power plants have been brought onstream in Émile Huchet, France; Scandale, Italy; Malženice, Slovak Republic and Shatura near Moscow. The plant in Malženice with an efficiency factor of 58 percent is the most environmentally friendly power station in Slovakia. Shatura was recently recognized by the UN as E.ON's first Russian Joint Implementation Project as part of the Kyoto mechanism (see below).


Nuclear Power: Nuclear Power plays an important role to achieve our CO₂ target. Besides our role as operators of such plants we are also cooperating with construction companies such as Siemens and Areva (since 2008). We're also Member of the European Sustainable Nuclear Energy Technology Platform (SNETP).


Coal: Our latest coal-fired power plants currently under construction achieve thermal efficiencies of more than 45 percent and by replacing older plants they save large amounts of CO₂. For example, the power plant unit under construction at Datteln 4 (1,100 MW), Germany, achieves over 45 percent efficiency. It will supply district heat to about 100,000 households in the central Ruhr region. The combined coal power plant Maasvlakte 3 in the Netherlands cogenerates heat that is piped to local industrial enterprises and residential areas; it will also be fitted to co-fire biomass. What's more, both power plants are designed for retrofitting with a large-scale carbon capture and storage (CCS) unit. In Maasvlakte we are also building the first large CCS demonstration plant with EU support.

E.ON is involved in climate protection projects in South-East Asia, North Africa and Russia under the CO₂ compensation methods defined in the Kyoto Protocol:

• The Clean Development Mechanism (CDM) regulates the allocation of emissions credits for climate-protection projects in developing countries. We have been working on such projects with Bionersis in South-East Asia since 2009. There, we capture climate-damaging methane gas from landfill sites to generate electricity. Over the project duration of 20 years this will avoid 4.5 million tons of CO₂ emissions.
• As part of Joint Implementation (JI) we receive certificates for emission reductions in industrialized countries. In 2010, our CCGT Shatur power plant near Moscow was recognized by the UN as E.ON's first Russian JI Project.

E.ON was included in the Carbon Disclosure Leadership Index (CDLI) for the first time in 2008. The CDLI is published by a group of 551 institutional investors, representing a joint investment volume of around EUR 51 trillion (USD 71 trillion). In 2010, we also extended the calculation basis for our carbon footprint and we were included in the newly compiled Carbon Disclosure Performance Index (CPLI). This index assesses the reports of 500 of the largest companies in the world in their efforts to reduce CO₂ emissions. 48 of these companies were included in the Index.
