GAS TURBINESIN SUPPORT OF GRID MODERNIZATION10 FEBRUARY 2016Presented by:Uwe SchmiemannPG Marketing & Product Strategy ManagerSolar Turbines IncorporatedCaterpillar: Non-Confidential

SOLAR TURBINES INCORPORATED World’s Largest Manufacturer of Industrial Gas Turbines (1 to 22 MW)Over 15,000 Gas Turbines SoldOver 6,000 Gas Compressors SoldInstallations in over 100 CountriesDirect End-to-End Sales & ServiceMore than 2 Billion Fleet Operating HoursGlobal Workforce 8,000 Employees48 Sales & Service Locations70% of Products are ExportedBased in San Diego, California, U.S.A.Subsidiary of Caterpillar Inc. Since 1981Caterpillar: Non-Confidential2

GAS TURBINE FOR CHP APPLICATION Gas Turbines are ideal suited forCHP due to:-High Mass flowHigh Exhaust temperature Small Footprint Low Maintenance Low Emissions due to DLEcombustionCaterpillar: Non-Confidential4

CHP IS LOCATED IN EVERY STATE 82.7 GW of installed CHP at over4,400 industrial and commercialfacilities 8% of U.S. Electric GeneratingCapacity; 14% of Manufacturing Avoids more than 1.8 quadrillionBtus of fuel consumption annually Avoids 241 million metric tons ofCO2 compared to separateproductionSource: CHP AssociationCaterpillar: Non-Confidential5

CURRENT GENERATION TRENDS Increase in Renewable Energy –Intermittent power Current distribution system operatesat capacity limitsSource: Michael Liebreich/BNEFSummit 2014 New transmission lines needed cost intensive and long approvalprocess Centralized power generationnetwork is jeopardized by naturaldisasters e.g super storm SandyCaterpillar: Non-Confidential6

HOW SMALL GAS TURBINES CAN SUPPORT THE GRID Support Grid Stability Allows decentralized PG Island Mode / Parallel Operation Increase Reliability Increase Resiliency Minimize Investment compared tocentralized power generation Reduce transmission losses – placedcloser to consumer Quick start-up Flexible load following Low Emissions High Efficient when CHP is used7

UTILITY OWNED CHPProject: Eight Flags inFloridaPlant size: 22 MW CHPUsage:- Power for local utility- Sell steam to industrial companyAdvantages: Benefits the Customer with Lower RatesGrows Natural Gas UsageReduces Carbon EmissionsCan Be Used Productively By Electric UtilitiesProvides Returns to StockholdersCaterpillar: Non-Confidential88

TECHNOLOGY IMPROVEMENTS Improved Start-up time Reduced Emissions Higher Efficiency – Simple cycle & CHP Increase in power density Increase in fuel flexibility on DLECaterpillar: Non-Confidential9

SUMMARY Turbines are ideally suited for CHP applications Turbines below 25 MW are ideally suited for behind thefence power / decentralized power / peaking Able of operating in parallel to the grid or island modeLow EmissionsGas is the cleanest fossil fuelGas will have strong availability at relatively low cost forquite some timeCaterpillar: Non-Confidential10
