SOAPPCT.25 Version 2.0 Released
Plant Design and Costing Software for Distributed Generation Projects
Chicago, October 1, 2000: EPRI has announced the release of SOAPP-CT.25
WorkStation Version 2.0. The SOAPP-CT.25 software is used to screen
opportunities, evaluate feasibility, optimize design criteria, and prepare proposals for
distributed generation projects. It helps users design projects for optimal payback,
return, and risk mitigation with accurate modeling of site-specific performance and
emissions. SOAPP-CT.25 generates detailed plant cost, emissions, and
performance estimates, supporting a wide range of gas turbine models up to 25 MW and using
current, manufacturer-supplied data. It allows the user to configure the plant to
site-specific conditions and requirements and generates detailed plant performance and
emissions estimates, equipment lists, project schedule, bill of materials and capital cost
estimates, O&M cost estimates, and financial analyses. Additional details and sample
output of the new release are available on the web site at http://www.soapp.com/soapp/dg.
New Features in Version 2.0 include:
- Addition of six (6) new Alstom (ABB) gas turbines to the database which brings the total
number of gas turbine models to 36. The additional Alstom gas turbines include the
following: Typhoon 4.35, Typhoon 4.70, Typhoon 5.25, Tornado 6.70, Tempest 7.70 and
- Added an input for Evaporative Cooler Effectiveness that is used to calculate the
discharge temperature of the cooler.
- Added an input for CT Pressure Loss Method such that the user can select whether the CT
inlet pressure loss and CT exit pressure loss is either WorkStation Calculated or
User-Specified. If WorkStation Calculated is chosen, the inlet and exit pressure losses
are determined based on equipment selections made by the user. If User-Specified is
chosen, the user has been provided with additional inputs for CT inlet loss and CT exit
loss such that they can override the values calculated by the WorkStation.
- Added an input for CT Auxiliary Power Calc Method such that the user can select between
either WorkStation Calculated or User-Specified. If User-Specified is chosen, the user has
been provided with an additional input for CT auxiliary power.
- Added an input for Required CT Gas Pressure. This input is used specifically to size the
natural gas booster compressor, if necessary. The WorkStation also has an input for
natural gas supply pressure.
- Added an input for Duct Burner Firing Temperature. The input was hard-coded at 1600 °F
in the previous version. The WorkStation will use this firing temperature when the HRSG
Steam Production Limit Switch = No Limit for that particular period. If the user sets the
HRSG Steam Production Limit Switch = Limit, the duct burner firing temperature is
calculated based on what temperature is necessary to meet the required steam flow (within
- Added an input for Condensate Pump Sparing. In the previous version, the pump sparing
was hard-coded at 2-100%. The user now has the choice of the following sparing options:
1-100%, 2-50%, 2-100%, 3-50%, 3-33%, 4-33%, 4-25% and 5-25%.
- Added an input for Fire Protection System which allows the user to decide if a fire
protection system should be included in the design. The fire protection system consists of
a 300,000 gallon fire water storage tank and 2-100% fire water pumps.
- Added an input for Maximum Daily Rainfall. This input is used to size the drainage
system and the maximum capacity of the waste water treatment systems.
- Added an input for Average Annual Rainfall. This input is used to develop the material
balance site runoff flow rates.
- Added several new line items to the CT Performance Report such as Gross Efficiency
(LHV), Site Elevation, Ambient Air Pressure, Compressor Inlet Air Relative Humidity, Fuel
Type, NOx Control Type and CO Emissions.
- Added HRSG exhaust gas conditions to the HRSG Steam Cycle Summary Report. These new
additions display the exhaust gas temperature, pressure, enthalpy and flow at both the
upstream and downstream locations for each heat transfer surface in the HRSG.
- Modified the Variable O&M cost calculations. The majority of the changes were in the
calculation for Maintenance Inspections.
- Revised the calculation for Condensate Return Flow such that the user can now enter a
value in percentage (%) instead of a value in pounds per hour (lb/hr).
- Expanded the Construction Labor Region input to include labor adjustments for all fifty
- Modified the Capital Cost Adjustments inputs so that the user can adjust all plant
- Modified the Performance Summary report to display the periodic performance point
- Improved the economic analyses for average, periodic, and daily levels of detail for
both electrical and thermal loads.
- Improved the Quickstart tool for creating new projects, conceptual designs and
- Added a user preference to set the heat balance convergence tolerance.
- Improved validation logic to better identify valid and invalid inputs based on the
- Improved heat balance calculations for duct-fired and external condensate heating
(water-to-water heat exchanger) cases.
