8 Trends Age of gas Drive for efficiency Big Data or the industrial internet 8

9 Natural Gas outlook U.S dry natural gas production by source, (trillion cubic feet) Shares of primary energy Natural gas production will increase by 85% over the outlook periode. - Inter-regional pipelines grow by 3.0% p.a. - Shale gas production up by 7.0% p.a. - LNG distribution grows by 4.3% p.a. 30% of gas production will be used for power generation. Global Electricity demand will grow by 85% over the Outlook periode 150% in Non-OECD countries 2x of Gas Power Generation by

Monitor Asset Health and Uptime To Intuition Reactive predictive fully integrated smart power generation 11

12 TSO requirements ( e.g. BDEW ENTSOE ) Static grid support: Defined voltage and frequency range. Must stay on grid Dynamic grid support: fault ride through capability 30% / 150ms Reactive current supply Certifications: Genset certificate from supplier Power plant certificate from customer Challenge for manufacturer: country / TSO specific requirements 12
