3 Smart Grids Definition and distinction RWE Deutschland AG SEITE 3

4 Smart grids form the platform for innovative energy services for smart energy Generation E-energy Trading Marketplace of the future MUC Smart meter Smart Grids Transmission grids Distribution grids Heat grids Virtual power plant Transit Smart home MUC = Multi Utility Communication IKT = Information and communication technology ICT Consumption Storage E-mobility RWE Deutschland AG SEITE 5

5 Future challenges for distribution grids RWE Deutschland AG SEITE 6

6 Specific measures and clear objectives help to meet current and future challenges Challenges Measures Objectives Demographics Structural change Consumption Distributed generation Age structure Regulation Innovative intelligent energy grids Grid development Grid Data Energy > Secure return on capital employed > Market-driven high supply quality > Energy-efficient and cost-efficient grids RWE Deutschland AG SEITE 7

7 The challenge of Demographics Decline in population by 2020 combined with an East-West shift provides only little potential for rationalisation 4,0% Deutschland REG Süd REG West REG Südwest REG Ost REG Mitte REG Nord 0,0% -4,0% -8,0% -12,0% Prognosis: Inhibitants 2020 zu 2004 RWE Deutschland AG SEITE 8

8 The challenge of Distributed generation The development of new wind energy and photovoltaic plants fills up the low-, medium- and high-voltage grids to the point of power flow reversal inst. capacity / annual peak load 180% 160% 140% 120% 100% 80% 60% 40% 20% 0% 160 % in % in 2007 WWE VSE Süwag RR LEW KEVAG enviam Windkraft [%] Windkraft [%] Source: Grid strategy process 2008 inst. capacity / annual peak load 70% 60% 50% 40% 30% 20% 10% 0% 60 % in % in 2007 WWE VSE Süwag RR LEW KEVAG enviam Photovoltaik [%] Photovoltaik [%] Source: Grid strategy process 2008 RWE Deutschland AG SEITE 11

10 Aligning distribution grids to growing demand RWE Deutschland AG SEITE 14

11 RWE pools the activities aimed at aligning the distribution grids to growing demands Innovative intelligent energy grids Grid development Grid Data Energy Forecasting of supply task Analysis of grid situation Installation of smart grids using intelligent measures Strategy for incentive regulation Fee-based / tariffbased model ehz / tlz meters Data concentrator Data warehouse Virtual power plant Distributed storage systems E-energy G4V Example: Electricity grids of the future project of the Federal Ministry of Economics (BMWi) (sum 80 Mio. ) RWE Deutschland AG SEITE 15

16 Distributed generation is efficiently integrated into the grid through virtual power plants Energy Virtual power plant E-energy G4V > Virtual power plants enable operators to use marketing channels otherwise closed to smallscale plants for cost reasons > RWE is positioning itself to meet the political requirements for the promotion of distributed supply > Potential results were investigated using two pools of plants as examples: A: 36 plants, 23 MW revenue 565 k /a B: 36 plants, 99 MW revenue 1,280 k /a > Marketing in a pool would have resulted in higher revenues of % compared to individual plant operation RWE Deutschland AG SEITE 20

17 The fusion of information and energy technology provides new leeway for efficiency and quality (I) Energy Virtual power plant E-energy G4V > In 6 pilot regions throughout Germany have the following aims in particular: Technical feasibility Increase in economic efficiency Improvement of supply reliability and climate compatibility Increase in energy efficiency, transparency Higher profitability of distributed supply units RWE Deutschland AG SEITE 21
