WRA Data Request 2.1 -1st Supplemental
WRA Data Request 2.1
During the October 11,2017 Technical Conference held in Salt Lake City,Rick Link
stated that his team's modeling demonstrates that output from Wyodak and Dave
Johnston would increase and the output from Jim Bridger decline as a result of the
Combined Projects (1240 MW of new wind plus 140 mile 500 kV transmission line plus
the 230 kV Network Upgrades).Attachment OCS 1.31 -2 CONF.xlsx displays this
incremental output for Wyodak and Dave Johnston -specifically,the attachment displays
the GWh of increased generation in the case of new wind and transmission as compared
with wind repowering only for the years 2017 -2036.
(a)Reproduce Attachment OCS 1.31 -2 CONF.xlsx using current assumptions and
modeling parameters (if not previouslyused)but include generationdata for the Jim
Bridger plant.Display results using unit data level data.
(b)Does the additional transmission impact the dispatch of PacifiCorp's share of either
the Craig or Hayden plants?If so,include generation from Craig and Hayden in the
reproduction of OCSl.31 -2 CONF.xlsx.Provide unit level data.
(c)Do the Combined Projects impact the dispatch of the Hunter and Huntingtonunits?If
so,include generation from Hunter and Huntingtonin the reproduction of OCSl.31 -2
CONF.xlsx.Provide unit level data.
(d)Do the Combined Projects impact the dispatch of PacifiCorp's share of Colstrip?If
so,include Colstrip in the reproduction of OCSl.31 -2 CONF.xlsx.Provide unit level
data.

(a)Do the Combined Projects impact the dispatch of the Naughton and Bridger?If so,
reproduce Attachment OCS 1.31-2 CONF.xlsx but include generation from the Jim
Bridger and Naughton plants.Display results for all plants using unit level data.Your
response should be the equivalent for the Wyoming units of Attachment WRA 2.1-1
CONF.xlsx which provides redispatch information for the Hunter and Huntington
units and Attachment WRA 2.1-2 CONF.xlsx which provides redispatch information
for the Colstrip units.
(b)Do the Combined Projects impact the dispatch of PacifiCorp's share of either Craig
or Hayden?If so,include generationfrom Craig and Hayden in the reproduction of
