1 Solutions for Smarter Power Markets Eric GOUTARD Alstom Grid 6-8 March 2011 GRID 1 ALSTOM APEx- APAC Regional Meet 2011, 6th -8th March 2011, New Delhi

2 Key Drivers for Smart Grids 1. Maximize CO2 free energy and reduce environmental impacts Enable renewable grid connection and improve thermal generation flexibility Maximize dispatch of intermittent renewable generation (wind, solar) Integrate distributed generation, eco-buildings and electric vehicles Develop new energy storage capabilities 2. Improve energy efficiency across the value chain Optimize real-time CO2 free energy delivery to end-users Maximize energy flow in constrained and aging grids Enable end-users dynamic participation to the market ( prosumers ) Integrate smart metering and demand side information integrate 3. Increase Grid Reliability and Stability Estimate Grid Asset condition through real-time and react accordingly Prevent transmission blackouts and minimize outages in distribution Monitor Grid stability / oscillations and implement Defense plans/grid self healing 2 ALSTOM APEx- APAC Regional Meet 2011, 6th -8th March 2011, New Delhi
