New, large plants (roughly 100 MW or larger) fueled by natural gas could emit no more than 1,000 pounds of carbon dioxide per megawatt-hour (MWh) of electricity produced, which is achievable with the latest combined cycle technology. Smaller natural gas plants, which tend to be less efficient and operate less frequently, would have to achieve a less stringent rate of 1,100 lbs CO2/MWh. Coal plants would have two compliance options, either of which would require the use of CCS technology. Under one option, coal plants would have to begin using CCS soon after startup to achieve a 12-month average emission rate of 1,100 lbs CO2/MWh. Alternatively, coal plants could begin using CCS within seven years of startup to achieve a seven-year average emission rate of between 1,000 and 1,050 lbs CO2/MWh, with EPA inviting comment as to the final standard within that range. CCS is not yet in use at any commercial-scale power plants, but is currently being built into large coal plants in Kemper County, Mississippi and Saskatchewan, Canada. CCS technology is also in place in several industrial facilities, some of which generate as much carbon dioxide as a commercial-scale power plant. NSPS = 1000 lb/MWh for Larger CTs

39 Inlet Air Cooling (Evaporative Type)
9/30/2014 Inlet Air Cooling (Evaporative Type) Combustion turbine inlet air cooling raises CTG power output Evaporative coolers are relatively inexpensive, but consume water Incorporated into the inlet air filter housing by the CTG OEM Evaporative coolers are most effective in arid climates, but are frequently included in plant designs for all types of climates OVERVIEW Of Combined Cycle TURBINE Technology 39

40 Inlet Air Cooling (Chiller Type)
9/30/2014 Inlet Air Cooling (Chiller Type) Chillers are expensive, but yield greater CTG power output increase Typically sized to reduce CTG inlet air temperature to 50 F from some specific ambient condition Typically water is a byproduct, condensed from the ambient air, and can be utilized elsewhere within the power plant The chilling heat transfer coil is integrated into the inlet air filter housing by the CTG OEM Chilling system designs vary, particularly the fluid passing through the coil that chills the ambient air (typically chilled water) Refrigerant types: anhydrous ammonia, R-123, etc Unlike evaporative coolers, inlet air chillers yield an efficiency penalty OVERVIEW Of Combined Cycle TURBINE Technology 40

42 OVERVIEW Of Combined Cycle TURBINE Technology
9/30/2014 Fuel Gas Heating Fuel gas heating increases the efficiency of the combined cycle Low grade heat from the HRSG is used to pre-heat the fuel gas which improves combustion turbine heat rate The heated fuel gas temperature will depend on the CTG OEM Values between 280 F and 365 F are common The temperature must be controlled to a stable set point or the CTG will run back or trip Typically feed water from either the LP drum (280 F) or the IP economizer exit (365 F) is utilized to heat the fuel gas OVERVIEW Of Combined Cycle TURBINE Technology 42

43 Startup Time Considerations
9/30/2014 Startup Time Considerations Startup times are an increasingly important consideration for combined cycles due to the following: Startup emissions are often limited by air permits Agencies understand startup emissions can be minimized Faster startups consume less fuel and thus save the Owner money Fast startups allow the operator to hit higher outputs faster, increasing revenue for merchant generators Combined cycles will increasingly be required to start and/or change loads quickly as wind turbine farm output and/or solar energy output to the grid varies OVERVIEW Of Combined Cycle TURBINE Technology 43

44 Changing system dynamics
9/30/2014 Changing system dynamics Impact of wind generation on power system load Wind is intermittent and is a major contributor during low load hours, but only minimal during peak load hours Wind generation requires a generation mix with more operational flexibility to serve the net load Addition of wind generation: Net Load Duration Curve becomes more steep Wind generation has small (but not zero) impact on peak load Hydro Gas GT OVERVIEW Of Combined Cycle TURBINE Technology Peaking Generation Peaking Generation System Load Mid-Merit Generation Gas CCGT Mid-Merit Generation From the macro-level, renewable assets are key to us achieving a less carbon intensive future and are changing the load duration curves that we have historically been working from. The chart here shows how these technologies are having their operating profile adjusted to accommodate an area with increasing wind generation. Although wind intermittency is driven by the geography, unique seasonal profiles and the higher off-peak wind regimes, it is an extremely low life-cycle cost solution that is impacting both ends of the pricing spectrum. The downward pressure on the dispatch curve reduces number of generating hours by baseload thermal units, predominantly large CCGT and coal units. The net impact is a larger slope which requires more peaking and mid-merit generation, which covers the hours on the far left, as fast response load following units. Although hydro units have historically been a key means to quickly respond to system imbalances, the variability of winter snowpack's and the increasing public demand for water are making this key resource a challenge for future power generation planning. As we speak with various transmission system operators and Utilities with wind generation, we find that systems that have more than 12% of their capacity from variable sources the need for fast acting dynamic response units. Base Load Generation Base Load Generation Hours of Operation / Year Wind generation has major impact on low and minimum load conditions 44 System Load without wind Clean Coal Net System Load with wind
