Response to OCS Data Request 8.1
The Company objects to this request to the extent it requires development of a special
study or informationnot maintained in the ordinary course of business.Without waiving
this objection,the Company responds as follows:
The Company has not performed the requested analyses in parts (a)-(f).Estimates of
the impact to the Company's rate of return on equity for the Utah jurisdiction could be
calculated using the revenue requirement impact of 100 basis points figure from the most
recent results of operations report.Based on the December 2016 results of operations
report,the revenue requirement impact of 100 basis points on equity in Utah is
$50,875,951.

OCS Data Request 8.2
If the Commission approves the Company's request in this docket and the Company's
request in Docket 17-035-40,as well as the proposed RTM in each docket,but applies a
cap such that the Company is not able to recover any amounts through the combined
RTM that would result in the Company earning above its currentlyauthorized rate of
return in Utah,would the Company still go-forward with the proposed repowering,new
wind and transmission projects at issue in this proceeding and in Docket 17-035-40?
Please explain your response.
Response to OCS Data Request 8.2
