# GUIDE TO IPM Output FILES

IPM Base Case v.4.10

The following information is meant to provide user s with a general explan ation of the different

IPM output files that are made web ready and post ed to EPA’s website and/or the Transport Rule

Docket. It refers to the v.4.10 EPA Base Case Model that was designed, developed and tested

for use in analyzing policy scen arios starting in 2012. It is m eant to help users identify and

interpret the data ava ilable in the model input and output files. The IPM v.4.10 documentation

(available at http://www.epa.gov/airmarkets/progsregs/epa-ipm/index.html ) provides more

comprehensive details regarding the assump tions and methodology used in the model.

Below is a brief overview of th e non-unit level IPM inputs and out puts that are made publically

available through EPA’s website and/or the Dock et. Because the System Summary Report is

one of the more frequently referenced documen ts that summarizes many IPM key outputs, it is

described in further detail in the remainder of this guide.

Once IPM v.4.10 Files are downloaded and decompre ssed from EPA’s website or the Docket,

the unzipped files will contain two folders: “Input and Output File s” & “Parsed Files”.

Additionally, it will have an Ex cel spreadsheet that includes “System Summary Report” in the

title. The “Input and Output Files” folder will ha ve four files within i t: A DAT, CAR, RPE, and

TAC file.

Input and Output Files

DAT file: This file will have a "DAT" filename exte nsion, e.g., Base Case.dat. It contains the

key input set-up data used to define the model run, including the definitio ns and specifications

for run years, model regions, model plants, fina ncial parameters, available fuels, and power

system transmission and operating parameters.

RPE file: This file will have a "RPE" filename ex tension, e.g., Base Case 2010.rpe. For each

model plant, this file shows the projections of fuel consumption, emissions (rates and tonnage),

capacity, costs (capital, fixed operations and maintenance, and vari able operations and

maintenance), and generation. The model plant re sults are grouped by model plant type within

model regions within model run year. Aggregated results are reported (a) for each model region

differentiated by plant type, (b) for each plant type differentia ted by model region, (c) for model

regions without consideration of plant type, and (d) for plant types without c onsideration of

model region.

CAR file: This file will have a "CAR " filename extension, e.g., Ba se Case 2006.car. This file

contains capacity utilization projections for each model plant grouped by model plant type.

Included are capacity contributed to reserve marg ins, capacity dispatch, and summer, winter, and

annual generation, capacity factors, and availabilitie s. The capacity dispatch column in this file

indicates the total capacity (in megawatts) that th e model plant represents. The average size of a

unit that the model plan t represents is found in the DAT f ile and is the size used for cost

assignment (e.g., to determine the applicable econo mies of scale when retrofitting existing units

with emission controls).

# TAC file: This file will have a "TAC " filename extension, e.g., Ba se Case 20106.tac. The file

contains annual production costs for each mode l plant grouped by model plant type. For each

model plant, total and rate-bas ed capital, fixed operations a nd maintenance (FOM), variable

operation and maintenance (VOM), and fuel cost s are shown. The variable costs reported for

model plants in this file can provide insights into why the utilization rates reported for some

plants in the CAR file are highe r than those of other model plants in the same region. The DAT,

RPE, CAR, and TAC files can be reviewed using a text viewer or text editor such as WordPad.

System Summary Report

System Summary Report: These outputs are available in either spreadsheet or PDF document

format, e.g., Base Case 2010.xls and Base Case 2010.pdf . It contains system-wide power sector

results for the lower continental U.S. for each run year. It reports forecasted generation,

capacity, capacity additions, capac ity factors, production costs, emissions, fuel consumption &

cost, and allowance prices by model run year. Disa ggregation of system-wid e data to plant type

data is provided for generation and capacity fiel ds. The plant types are categorized based on fuel

used (e.g., coal, oil/gas, nuclear, hydro), combus tion technology (e.g., turbine, combined cycle

gas), control technology (e.g., scrubber, post-combustion NO

x 

# control), and retrofit structure

(e.g., coal plant with existing SNCR retrofit with ACI). In addition to providing the above

outputs forecasted for each model run year, it al so gives information on the various regulatory

and legal requirements that were inputted into the m odel as constraints. Be low is a more detailed

explanation of each worksheet in the System Summary Report.Description of Worksheets and Data within the System Summary Report FileSystem Summary Report:When the Excel File is opened, it will contain four worksheets1.“Summary” worksheet2.“All Constraints” worksheet3.“Fuel Report” worksheet4.“Tables 1-16” worksheetSummary Worksheet:The summary worksheet in the system summary file highlights some of the key data points from the IPMoutput, and is intended to bean ideal starting point for assessing fundamental environmental and operational projections for the powersector in any given IPM run. For first time users, it is one ofthe more user friendly documents from which to view output data. SeeAppendix 1-1 for description of fieldsincluded in the “Summary” worksheet.All Constraints:The “All Constraints” worksheet in the System Summary Report provides information on various legal and policyrequirements and how they are captured in the model. Each constraint typically involves a “standard”that is imposed in the form ofan emission limit, emission rate limit, or generation limit. The constraint can be applied at the unit, plant, system, state,regional ornational level. The constraints also include a time dimension and may vary between model run years. Each constraint in theworksheet provides information on the impact of the “standard” onthe effected unit(s). These impacts are modeling outputs given inthe form of emissions, emission rates, and/or generation that occur under the given “standard” in a particular model run year.Forconstraints that represent cap-and-trade programs with banking, the IPM data indicatesadditions and withdraws from the allowancebank and allowance price by year. There are nearly 1000 constraints in the IPM V.4.10 Base Case, and the total number may extendbeyond a thousand for the modeling of certain policy scenarios. Anexample of a constraint would be “Constraint Name: #1 – Title IV– SO2 Constraint v.4.0” which captures the Emission limits imposedon coal units by the Acid Rain Program. The constraint providesa total “standard” that reflects the Title IV SO2 allowances available to units in a given modelrun year. Below is a table thatillustrates the typical format of a constraint in the “All Constraints” worksheet, along with an explanation of each row.Appendixtable 2-1 provides a comprehensive list oflegal and policy requirements that are reflected in the model through the variousconstraints.Description of Constraint Level Data FieldsRow TitleDescriptionConstraint Name: #1 - Title IV - SO2 Constraint v4.0Provides information on legal or policy constraint being modeled.Constraint Type: Rate Cap [MTons]Provides information on constraint typethat is being modeled (e.g., generation, emission, rate, etc.). "Mtons"= thousand tons (emission limit);"GWh" = gigawatt hours (generation limit); "lbs/Mmbtu" = pounds permillion btus (rate limit).Run Year, Seasons Included: 2012 WINTER SUMMERRun Year, Seasons Included: 2015 WINTER SUMMERRun Year, Seasons Included: 2020 WINTER SUMMERRun Year, Seasons Included: 2025 WINTER SUMMERRun Year, Seasons Included: 2032 WINTER SUMMERShows model run year for the output and indicates if theconstraint was applied to summer generation, wintergeneration, or both. Winter months include October through April. Summer months include May throughSeptember.Time Base: Seasonal/AnnualShows calendar years mapped to each model run year. Indicates year range to which each constraint limit isapplied.Standard - [MTon]This row provides the value of the constraint being inputted into the model. It is modeling input and one ofkey interest in the “AllConstraints” worksheet.-Emissions at Affected Plants [MTons]-Less Allowances Purchased [MTons] SO2-Plus Allowances Sold [MTons] SO2-Plus Allowances Banked [MTons]-Less Allowances Withdrawn (1:1) [MTons]-Less Allowances Withdrawn (n:1) [MTons]Total [MTons]Model output of collective emission at plants affectedby "standard" as well as summary of allowance tradingactivity supporting the emission level.TBtu ConsumedTbtu=trillion btu. Model output of fuel consumption for affected units.Rate - [lb/MMBtu]Model output of emission rate for effected units. "lbs/Mmbtu" = pounds per affected unit.TWh GeneratedElectricity generated by units subject to the"standard" limit. TWh = Terawatt hours generated.TWh Generated QualifyingRate - [lb/MWh]Rate for affected units. Lb/MWh = pound per Megawatt hour.Constraint Shadow Price [US$/Ton]If the "standard" is an emission limit(i.e., cap) in a trading program, the constraint shadow price will reflectthe $ per ton value of allowances in that trading program. Commonly called the “allowance price”.Fuel Report:The “Fuel Report” worksheet provides consumption and cost data for major powersector fuel sources for each modelrun year. These fuels include coal, nuclear, natural gas, biomass, pet.coke (petroleum coke), natural gas, biomass, waste coal, and oil.For each fuel type the total consumption is given in TBtus (trillion Btus). Cost is providedin both MMUS$ (million US dollarunits)and US$/MMBtu (U.S. dollar per million Btus). Appendix 3-1 provides an example ofthe “fuel report” from the IPM v. 4.10 BaseCase.Tables 1-16: The “Tables 1-16” worksheet in the System Summary Report provides information oncontrols, generation, capacity,and cost. The information in these tables is often the disaggregated value of the totals reported in the “Summary” worksheet.A userinterested in better understanding the details behind the totalsgiven in the “Summary” worksheet may wish to consult “Tables 1-16”.For example, the “Summary” worksheet providesthe total amount of generation from coalin a given model run year. However, the“Tables 1-16” worksheet goes one step further and provides dataon the portion of that generation total coming from coal plantswithno pollution control and the portion coming fromplants with specific pollution control configurations. Inparticular, tables10through14 provide generation and capacity dataat the model plant level. Tables 1–9 provide generation supply and demand data at theU.S. region wide level. The table below describes the data output reported in each table, and Appendix 4-1 provides more informationon the acronyms, and nomenclature used in the data fields.Description Tables in “Tables 1-16” WorksheetTable #TitleDescription1 Reserve Margin Capacity Winter (MW)Shows total electric generating capacity available to the U.S. region during winter period.Available supply of electricity in megawatts (MW).2 Peak Load Winter (MW)Shows total electricity demand during winter period by the U.S. region.

Summationof values in Table 4.6 Projected Demand (GWh) Gigawatt hours (GWh) of annual projected demand and projected net demand.7 Dumped Energy Typically not referenced.8 Total Supply for Demand (GWh)Gigawatt hours (GWh) of annual electricity supply before taking transmission and distributionlosses (T&D losses) into account.9 Total Sales (GWh)Gigawatt hours (GWh) of annual electricity supply determined by subtracting projectedtransmission & demand losses from total supply.10 Capacity by plant typeCumulative capacity (MW) of model plant types for each model run year. The model run plantsare categorized by the unit’s fuel,configuration, and online status (e.g., new, existing, retiring).Each control configuration combination is modeled as a separate plant type. The total capacity,retrofit capacity, new unit capacity, and retiring unit capacity values given in the summary tableare disaggregated into model plant types in thistable. Key difference between table 10 & 11 isthat 10 is cumulative and 11 is incremental.Therefore, table 10 will show model plant capacityby a given year, and table 11 will show model plant capacity added during that run year.11 Capacity Additions and ChangesIncremental capacity (MW) of model plant typesfor each model run year. The model run plantsare categorized by the unit’s fuel,configuration, and online status (e.g., new, existing, retiring).Each control configuration combination is modeled as a separate plant type. The total capacity,retrofit capacity, new unit capacity, and retiring unit capacity values given in the summary tableare disaggregated into model plant types in this table.12 Generation by Plant Type (GWh)Cumulative generation (GWh) of model plant types for each model run year. The model runplants are categorized by the unit’s fuel, configuration, and online status (e.g., new, existing,retiring). Each control configuration combinationis modeled as a separate plant type. The totalgeneration by each plant type given in the summary table is disaggregated into model plant typegeneration in this table.12a Generation by Fuel Type (GWh)Total gigawatt hours (GWh) of generation in each model run year by fuel type. Aggregation ofthe model plants pertaining to each fuel in table 12.13 Generation by Plant Type (Tbtu)Cumulative generation measured in Trillion btus (Tbtu) of model plant types for each model runyear. The data corresponds to generation values given in Table 12, but is expressed in TBtus toprovide the heat content of the power generated. Conversion factor of approximately 3,412Btu/KWh is used.14 Capacity factor by Plant Type (%)Capacity factor for each model plant type. Capacity factor is the actual generation expressed asa percentage of maximum generation possible ifthe plant was operated every hour of the year.Therefore, it is the generation / (capacity*8760). Generally, the model does not allow for 100%capacity factors because of maintenance, plannedoutage, and forced outage times. Intermittentgeneration sources (i.e., wind) also have their capacity factor limited by the availability of theirfuel source.15 Total Annual Production CostProvides total production cost in million U.S. dollar units (MMUS$) for each model run year.The production costs are disaggregated into variable operating and maintenance (variableO&M), fixed O&M, fuel, capital, andCO2 transportation and storage cost.16 EmissionsProvides total annual U.S. emissions for each model run year for several hazardous, criteria, andgreen house gas pollutants. Emission totals areexpressed in 1000 tons (Mtons); 1,000,000 tons(Mmtons), or regular tons. All tons are short tons (2000 lbs/ton) unless otherwise noted.APPENDIXAppendix 1-1: Description of DataFields in “Summary” WorksheetRow #Row TitleDescription of Field12EPA IPM Run Results3All costs and prices are in 2007-year dollarsProvides year to which all cost and priceswithin the summary report are indexed.4NATIONWIDE EMISSIONS5SO2 (million tons)6NOx (million tons)7CO2 (million metric tons)8Hg (tons)Provides nationwide total emissions from EGUs for given run years in short tons (2000 lbs/ton) unlessotherwise noted.910TOTAL COSTS11Total Costs (billion $)Provides the total cost of electricity generation to meet demand in given year under the modeled operational,regulatory, and policy constraints.

The model plant types are differentiated by fuel used(e.g., coal, oil/gas, nuclear, hydro), combustion technology (e.g., turbine, combined cycle gas), control technology (e.g., scrubber,post-combustion NOx control), online status (e.g., new, existing,or retiring) and retrofit structure (e.g., coal plant with existing SNCRretrofit with ACI). It is helpful in understanding the nomenclature of model plants to recognize the significance of the “ret.”, “exist”and “&” usage in the title. “Ret.” suggests that the model plant is receiving a retrofit in or by the given run year. If there is no “exist”label that immediately follows the “ret.”designation, then every control listed isa retrofit on a unit without any previouslyexistingemission controls. The indicated controls come online post 2011 andare endogenous to the model.If there is an “exist” that follows “ret.”then each control listed after the “exist” and before the first ampersand (&) is anexistingcontrol (online prior to 2012 and exogenous tothe model) and everything after the “&” is a retrofit that is added to that model plant bythe model run year given. To illustrate the difference, let’s look at plant types with the same controls shown but with the word “Exist”absent and when the word “Exist” is present, there willbe variants in the placementof the first ampersand (&):Plant TypeID #DescriptionRet.ACI & SCR & WetFGD & CCS64Retrofit ACI, SCR, CCS and Wet FGD on Existing Coal SteamRet.ExistACI & SCR & WetFGD & CCS77Retrofit SCR, CCS and Wet FGD on
