  4. Technologies to Pair with Wind Hydropower Storage / Flywheels Natural Gas Turbines Demand Response Oil Coal Nuclear

  5. Gas Turbines Near Ideal Technology Ramp rates are able to handle most wind events LM6000 can reportedly ramp to full power in 2 minutes from a cold start Adequate capacity Easily sited Low capital cost

  6. 6

  7. Clean Air Interstate Rule

  8. GE LM6000 - Regression Analysis NOx Emitted (lbs/min) 8

  9. CO2 Emissions vs Power for LM6000 (idle) 9

  10. Operating Limit Constraint Operating Limit Constraint 10

  11. CO2 Emissions vs Power for SW 501FD 11

  12. Siemens-Westinghouse 501FD Regression Analysis GE Document GER-3568G 12

  13. Emissions Factors LM6000 Steam, no SCR 501FD DLN, SCR 13

  14. First Steps Analyze the problem Characterize emission profiles of more generators Characterize the emission profiles of more technologies Develop methods to measure changes in power plant emissions due to increased wind energy penetration Determine scenarios where natural gas generators approach their emission limitations

  15. Possible Solutions Utilize transition firing modes more Redesign turbine combustion cans Encourage development of gas turbines near wind plants far from load Minimize adverse health affects from NOx emissions Modify market policies

  16. NOx Firing Modes

  17. Dry Low NOx System

  18. Market Redesign Recover increased operation and maintenance costs Replace lost revenue streams Relax or modify emission restrictions for natural gas plants compensating for wind power Modify constrained economic dispatch to account for emissions
