Company structure RWE Innogy Wind onshore Wind offshore Hydro Biomass New technologies RWE Innogy plans, builds and operates facilities for renewable power generation and energy production (1,300MW in 2008). Aim is to develop power generation quickly on this basis in Germany, the UK, France, Benelux, Spain, Italy and Eastern Europe. Our focus is clearly on wind power projects in the European on- and offshore sector. RWE Innogy will also grow in the areas of hydroelectricity and biomass. Other areas of the company s activities are solar and geothermal energy as well as wave and tidal power plants.
Renewables within RWE's capacity and generation mix Power plant capacity by primary energy source (as of 12/2008, under IFRS) Electricity production by primary energy source (2008, under IFRS) 14,183 MW, 31.4% Hard Coal 62.0 TWh, 27.7% 10,828 MW, 24.0% Lignite 73.9 TWh, 33.0% 2008: 45,196 MW 2008: 224.1 TWh 5,152 MW, 11.4% Pumped storage, oil, other 2.4 TWh, 1.1% 1,515 MW, 3.4% Renewable energies 5.3 TWh, 2.4% 7,223 MW, 16.0% Gas 31.2 TWh, 13.9% 6,295 MW, 13.9% Nuclear 49.3 TWh, 22.0%

Low proportion of CO 2 -free stations (17%) and low CO 2 gas-fired stations (16%). Almost doubling CO 2 -free capacity to ca. 30%. Almost doubling low CO 2 gas-fired capacity to ca. 30%. *) General underlying assumptions: extension of nuclear lifetime in Germany and realising new nuclear projects in UK and CSEE markets.

Advantages offshore: wind potentials Kinetic energy: E = 1 2 * m* v² Air flow: dx m & = A* ρ * = A* ρ * v dt area density flow Power: 1 ( ) = * A* ρ * v³ 2 P Wind
Advantages offshore: wind speed Higher middle wind speed: - measured on FINO I: 10.0 m/s in 100m height, - compared to: 6.0 to 6.5 m/s in 100m height onshore, - approx. 4,000h full load hours. Good for the company but tough regarding construction!
Advantages offshore: heights and power growth of wind turbines Increased efficiency In not more than 20 years the benefit of wind turbines has been increased a hundredfold. The 5 MW turbine will further multiply that by 5. No echo and shadow!

EEG compensation* (Offshore 15 cents/kwh until 2015) (1) The compensation is 3.5 cents per kwh for energy from offshore plants is 3.5 cents per kwh (basic compensation) (2) During the last twelve years, beginning at the commissioning of the turbine, the compensation is 13.0 cents per kwh (initial compensation). The initial compensation rises by 2.0 cents per kwh for plants that have been installed before 1st January 2016 according to clause 1. According to clause 1 and 2 the period of initial compensation for energy from turbines that have been created in a distance of at least twelve sea miles and a water depth of at least 20m, every sea mile above that is extended by 0.5 months per full sea mile distance and by 1.7 months per every additional full meter water depth. *Bundesgesetzblatt Jahrgang 2008 Teil 1 Nr. 49, published 31 October 2008, in Bonn Remark: In the UK model of quotas with approximately 19 cents/kwh for offshore until 2027
