2 Electricity can not be stored. It has to be made right when you use it Page 2

3 Energy can be stored And made into electricity when you need it Page 3

4 Some types of generation can t always be used when you need them Transient generation needs a dispatchable partner to enable a reliable grid Page 4

5 There are Lots of Partnering Technology Options Batteries and Pumped Storage Dispatchable Natural Gas Trent 60 Aeroderivatives SCC-800 Flex- Plant Combined Cycle SST6-5000F Simple Cycle Flex-Plant Combined Cycle Page 5

6 Balancing green and green $ With the right technology, the environment and the bottom line are both winners Page 6

7 Power Generation on Grids without renewables Total Demand (based on CAISO Duck) Peaking Intermediate Base Load Dispatch Page 7

8 Power Generation on Grids with renewables CAISO Net Load 2012 through 2020 Peaking Simple cycle Before Renewables With Renewables The Duck renewable generation ~ 6000 hrs/yr ~7 GW Intermediate Moderate to High Dispatch Fluctuating Load Base Load Dispatch Economics & Environment Favors Combined Cycle The Duck Pond Non-renewable generation Constant Load Page 8

9 Conventional Combined Cycles were designed for Base Load Flex-Plants are Designed for Flexibility HRSG designed for Flexibility High-Capacity Attemperators ST Piping Warm-up Systems Siemens SST-5000 Steam Turbine Siemens Gas Turbine Integrated T3000 Control system with Startup & Shutdown Automation & Stress Control Solutions Flex-Plants are designed to be as fast and flexible as a simple cycle With the High Efficiency of a Combined Cycle Page 9

10 Plants Designed to Cycle Flexibility Features Built In Fully Air Cooled (E, F & H) Rotor Hirth Serrations Four stages of variable compressor vanes (F&H Class) Siemens patented HCO (H-Class) Conventional Operating Temperatures Gas Turbines Designed to Cycle Siemens latest portfolio of gas turbines has more than 2x the cycling life Page 10

11 SGT-8000H Hydraulic Clearance Optimization (HCO) CASING REDUCED TIP GAP TURBINE BLADE INITIAL TIP GAP AXIAL SHIFT HCO HCO on ~5 MW HCO off Siemens Patented Technology Simple, Fail-safe, Field Operated since 2004 Provides high Performance and high operational Flexibility and Low Degradation Page 11

12 Plants Designed to Cycle Steam Turbines Designed to Cycle Push rod arrangement for reduced axial clearances Siemens Flex-Plants use steam turbine stress controllers to enable the use of the full capability of the design without risking engine life Page 12

13 Plants Designed to Cycle Drum-type HRSG Drum NEM DrumPlus BENSON HRSG Separator Separator Exhaust Gas flow Drum Exhaust gas flow No thick wall components - fast start-up possible Improved superheater header design Superheater Evaporator NEM s Drum Plus design combines fast start capability with traditional drum boiler technology Superheater Evaporator Once-Through Benson and Drum-Plus HRSG designs allow > 30 MW/min load gradients Page 13

14 Siemens Co-Start Technology Fast Bottoming Cycle Start Up Co-Start uses an integrated hardware and control package which enables the steam turbine to ramp up early and quickly, while protecting equipment for reliable operation over the life of the plant. No low load gas turbine hold points Fast Ramp of the steam turbine Base load power in about 30 minutes Co-Start means lots of power fast Page 14

15 Reducing Operating Costs Saving Money with Co-Start Co-Start results in an Estimated Savings over $25,000,000 NPV Flex-Plants with Co-Start Offers Significant Savings to the Bottom Line Page 15

16 Siemens Clean-Ramp Technology Clean-Ramp enables unlimited dispatch on grid control by avoiding permit excursions during ramping Page 16

17 Plant Power DASH Fast Load Following for Flex-Plants with Supplemental Firing Ramps at GT Ramp Rate Ramp at ~3 MW/Min Plant Ramps at GT Ramp Rate Duct Firing Co-Start results in an Estimated Savings over $25,000,000 NPV Unfired Plant GT 100% and slow DF DASH Conventional Technology DASH opens up the possibility for new revenue streams Page 17
