WIEC Data Request 20.13
WIEC Data Request 20.13
Please refer to the Second SupplementalDirect Testimony of Joelle R.Steward,page 2,
line 20 through page 3,line 1.Please clarify whether the Company's proposal to exclude
net power cost benefits of the Combined Projects from the ECAM,absent the RTM or
other cost recovery/deferral,applies only to the 30 percent increment proposed to be
credited through the RTM,or also to the 70 percent that normallywould be credited to
customers through the sharing band.If the latter,please explain the process by which the
Company proposes to segregate and exclude any net power cost reductions resulting from
the Combined Projects from the calculation of the ECAM,in the absence of the RTM.
Response to WIEC Data Request 20.13
The Company's recommendation to symmetrically treat the Combined Projects'costs
and benefits outside of a resource tracking mechanism (RTM)would exclude 100 percent
of the net power costs (NPC)reductions resulting from the Combined Projects.The value
of the Combined Projects wind production to be excluded from the energy cost
adjustment mechanism (ECAM)would be calculated for 100 percent of the Combined
Projects production using the same methodology as the described in Exhibit
RMP_(JRS-1SS)page 1 of 1,which is "incremental wind production not in base rates
will be multipliedby monthly HLH and LLH prices,(Four Corners for east resources)
less wind integration costs".

WIEC Data Request 20.14
Does RMP believe that Ms.Steward's analysis for the 2020-2050period presented in
"JRS Exhibits 2SS-4SS Combined Projects WY 2.16.18 Work Papers"would be
impacted by the results of the Mr.Link's updated economic analysis as reflected in the
Corrected Second Supplemental Direct filing?If not,please explain.
Response to WIEC Data Request 20.14
Ms.Steward's exhibits and correspondingwork papers for the Second Supplemental
Direct filing were not impacted by Mr.Link's updated economic analysis as reflected in
the Corrected Second Supplemental Direct filing because the correction in wind
integration costs in Mr.Link's analysis did not impact the NPC used in the preparation of
Ms.Steward's exhibits.The wind integration costs had already been correctly reflected
in the source used for Ms.Steward's workpapers.
