10 What PSP Does Provide flexibility to balance base load generation Complement intermittent renewable energies Optimise electrical grids Presentation - - P 10 title - 20/11/2014 P 10

11 Thermal & Nuclear plants optimisation Power (GW) Consumption Adjustable Generation PSP, Gas turbine, Hydro PSP Pumping Base Load Generation Nuclear, Coal, Run of the river hydro, Time Presentation title - 20/11/2014 P 11

12 Power New need for flexibility GW Time Shift load GW Regulation Forecast Generation 24h Excess wind Actual Generation Flexible Generation 1min Demand Wind energy GW Ramp Rate Balancing Intermittent 1h Baseload (non flexible) Time Presentation title - 20/11/2014 P 12

13 Increase of unit cycling Presentation title - 20/11/2014 P 13

14 Increased partial load operation Unit Unit Presentation title - 20/11/2014 P 14

15 PSP Development Trends Performance improvement Efficiency: 70 to 80% in 40 y. Availability, Reliability, Cycling Overcoming topological limitation Very High or Very Low Head Head range increase Underground reservoir Sea water operation Maximising flexibility Variable Speed offering Power range increase Reaction time reduction Presentation title - 20/11/2014 P 15

16 Variable speed PSP Double Fed Asynchronous Motor Generator Adjustable pumping power Compatible with larger head variation Faster power adjustment Pump Turbine global efficiency (+ ~ 1%) Presentation title - 20/11/2014 P 16

17 PSP allows Renewable to remain Renewable Customised solutions for each application Economical feasibility highly depends on regulatory framework Presentation title - 20/11/2014 P 17
