  1. When Grids gets smart Claes Rytoft Senior Vice President ABB World Forum on Energy Regulation IVAthens, Greece October 18 - 21, 2009

  2. 40,000 30,000 20,000 Terawatt hours (TWh) 10,000 1990 2004 2015 2030 Electricity consumption set to double by 2030 • Avg. global annual growth rate 2.5 % • Highest growth rate in Asia :4.5 % • China to consume more than US before 2015 Electricity consumption growth/yr 2006-30 in % Electricity consumption in kWh per capita World avg: 3,240 Source: IEA, Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009

  3. Climate change concerns need to be addressed Energy efficiency and renewable power can provide almost 80 percent of the targeted reduction Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009

  4. More renewable power generation Energy efficiency Distributed and intermittent generation Customer pricing expected to foster demand responses • Grids of the future will be different from those of the past • Open for all types and sizes of generation technologies • Integrating demand side in system operation Fundamental changes in power supply are coming Impact on grid stability and efficiency Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009

  5. Evolution of grid designFrom traditional to future grids • Centralized power generation • One-directional power flow • Generation follows load • Operation based on historical experience • Limited grid accessibility for new producers • Centralized and distributed power generation • Intermittent renewable power generation • Consumers become also producers • Multi-directional power flow • Load adapted to production • Operation based more on real-time data traditional grids future grids Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009

  6. Impact of Smart Grids - example of challenges Generators: • Optimize ‘spinning reserves’ with increased amount of renewables Transmission utilities: • Maintain grid stability with increased amount of renewables • Reduce transmission losses Distribution utilities: • Maintain protection system integrity with increased amount of renewables • Demand Response and real time price information • Reduce distribution losses Consumers: • Optimize electricity consumption – home automation (incl. local generation PV, vehicle,….)

  8. Balancing the need for more power with lower climate impact Connectinggrids Renewablesintegration Demand response Plug-invehicles Power flowcontrol More power Key enabler: ICT - Information & Control Technologies Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009

  9. DSO Consumer Home Energy Management System Bi-directional communication NCC (control room) Electrical connection Demand response • Consumer interaction and services • Improved load management • Enhanced reliability Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009

  10. BorWin 1 Example SmartGrid projects from ABB • PV Solar plant in Spain - Produces 2.2 GWh/yr, displaces 2,200t greenhouse gas emissions p.a. • 2000 km HVDC line to connect hydro power, China • 93% efficiency -Savings vs AC line enough to supply power to more than 1 million consumers in China • Off shore wind park HVDC Grid Connection, Germany • Lowers CO2 emissions • by ~1.5 mill. t/yr by • replacing fossil-fuel generation Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009

  11. Surface of Sahara 9 million km2 Area needed to produce all European electricity 18 000 km2 Area needed for all world energy 650 000 km2 Future scenario:Solar power from Sahara Connecting large scale solar-based generation eg, deserts, with distant load centers via an efficient transmission system like HVDC Claes Rytoft - World Forum on Energy Regulation IV - Athens, Greece - October 18-21, 2009
