WIEC Data Request 20.7
WIEC Data Request 20.7
Regarding the Cedar Springs Wind Project,please explain how the wind facilities,
includingany gen-tie lines,are allocated based on the BTA and PPA components.For
example,is the BTA component for an ownership interest in the entire project,or for
specific wind facilities within the project?
Response to WIEC Data Request 20.7
In the evaluation of Cedar Springs Wind Project,the build transfer agreement (BTA)
projects were evaluated at its bid price with direct-assigned interconnection capital cost
plus the dollars per kilowatt ($/kW)in-service interconnection network upgrade capital
cost based on the BTA capacity (halfof the total project capacity).The other half was
included in the power purchase agreement (PPA)bid price.The two components were
added together to determine the combined BTA/PPA cost for modeling purposes.
The BTA and PPA for the Cedar Springs Wind Project are scheduled to be negotiated
between March 2018 and June 2018.PacifiCorp anticipates the BTA will be tied to
specific equipment,such as individual wind turbine generators (WTG),within the wind
project to the greatest extent possible within a practical project design.
