Jackpot Solar Economic Analysis Plan
Purpose: To determine if both of the Jackpot Solar projects are economic under a range of scenarios that
include B2H.
Method: Step 1. Calculate the NPV difference between scenarios with the projects forced into the portfolio and
without the projects available to be selected for: l) Planning Carbon with High, Mid, and Planning Gas; and 2)
Planning Gas with Zero,Planrring, and High Carbon. Step 2.If a scenario forcing both projects into a portfolio
shows an uneconomic result, model that scenario with only the Jackpot Solar Project forced into the model.
Required Information: Model runsl which include both projects will need to be performed for scenarios:
Planning GasiPlanning Carbon, Mid Gas/Planning Carbon, and High Gas/Planning Carbon. Model runs which
remove both projects will need to be performed for the following scenarios: Planning Gas/Planning Carbon, and
Planning Gas/High Carbon. Model runs which include only the Jackpot Solar project will need to be performed
for scenarios: High Gas/Planning Carbon, Mid Gas/Planning Carbon, and PlanningGaslZerc Carbon. The NPV
will need to be provided for the following scenarios: Planning GaslZerc Carbon (Portfolio 13), and Mid
Gas/Planning Carbon (Portfolio I 8).
(A.) NPV with B.ZIJ and with Solar Projects (in $000's)
Natural Gas
(8.) NPV with B.1IJ and without Solar Projects (in $000's)
Natural Gas
(B. - A.) NPV difference with and without projects (in $000's)
Natural Gas
I It is estimated that 8 total model runs are required: 3 model runs including both projects, 2 model runs without projects, and 3 model
runs withjust the Jackpot Solar project
2 NPV for Portfolio I I under the Planning GaslZero Carbon scenario Attachment A
3 NPV for Portfolio I 8 under the Mid Gas/Planning Carbon scenario Case No. IPC-E- I 9- 1 4
