•Nominal Interest Rate: Taken from another table•Inflation: Manually inputted•Values based on 2011

• =+(1+inflation)*(1+inflation)

• =+(previous)*(1+inflation)

• Continued until final year

2013 Expanded Plan Residential Gas Screening Model –Avoided Cost tab

Res heat Column• C8 = 2013 numbers• =+(corresp. inflation adj)*(value from

other excel sheet)• Replicated for Column Res Water

NPV 1 • =IF( C8 = “”, “”,

NPV(Nominal_Interest_Rate, C$8;C8) * (1+Nominal_Interest_Rate)^.5For each NPV Column it sues the previous column (res heat, res water,

res other..) So NPV2 = IF( E8 = “”, “”, NPV(Nominal_Interest_Rate, E$8;E8) * (1+Nominal_Interest_Rate)^.5. E8 is 2013 Res Water

• C&L Heating: +Res Heat

• NPV4: same as previous

• C&L Other: +Res Water


• Water Savings: =+(prev water savings) * (1+Inflation)


• Annual $: =+(prev annual)*(1+inflation)


Unrelated to any other calculations:

•Nominal Interest Rate•Year•Water Savings•Annual $


•Manual Inputs: Row Number, Company, Sector, Program, Measure, Units•Taken from separate excel sheet: TR Cost, Incentive, Annual CCFs, Life, Type, Water Gallons, Annual $

•Peak Day CCFSs:=,00977*Annual CCFs=.00321*Annual CCFsThen repeated

The rest are from separate excel sheet

Unit Gas Benefit: =Calculation!P17/Input!F25B/C: Unit Gas Benefit//IncentiveIf(B/C<1, “Bad”,””)*Note several “bads”

2013 Expanded Plan Residential Gas Screening Model –Input Tab

•Avoided Cost: Manually Input•Number: Manual input•Calculation Factor: Manual Input

Note: Red corners may mean an error with the formula

2013 Expanded Plan Residential Gas Screening Model –Peak Calculator Tab

All numbers are manual inputs so possible error with the table.

The numbers don’t add up with the other numbers in the table.

For example when adding together the CNG Home Energy Solution TR Cost for each Measure shown in the calculation tab the number isn’t $388.836

2013 Expanded Plan Residential Gas Screening Model –Peak Calculator Tab

broke down equations for columns shown here

Equation:

IF($G19<>"",BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19,"")

Logic Statement: $G19<>"" = not equal to 0

True: BO19*INDEX(Winter_Peak,$G19,0)*$AK19*1000*Inputs!S19

INDEX(Winter_Peak,$G19,0)(Look at G19 in “Measure Life”)

False: “” = leave blank

*constants are blue

The meaning of these value are unknown on both the calculations tab and the inputs tab.

Calculations Tab:

Understanding the Quantity Column:

= IF(B6 <> “ “, IF(Inputs!H6>0, Inputs!H6, “ “), “ “)

<> = not equal to

! = referring to cells on another worksheet

$ = absolute reference

H6 on Inputs Tab = 5%

H6 on the Calculations Tab = 0

Before H19 the equation does not fit the value:

**Starting at H19 on the Calculations Tab the equations calls upon Inputs!G, and the column begins to match those values in the respective Inputs G column

Purpose: If the value in column B is not a blank, and if, in the Inputs tab, the value in the corresponding row in the H column is greater than 0, return that value.

Understanding the Quantity Column:

Inputs Tab:

Inputs Tab: Unknown Values

Inputs Tab:Measure Tables Randomly Placed

Inputs Tab: Measure Tables

One of the things mentioned specifically in the meeting is that these tables needed to be organized. They are currently randomly placed throughout the inputs tab.

Inputs Tab: Measure LifeMeasure Life (Column H): These are all input numbers
