WIEC Data Request 12.6
WIEC Data Request 12.6
Please describe how the Company's System Optimizer model and Planning and Risk
model accounted for any system upgrades required to interconnect the 2017R RFP
proposed projects when evaluating those bids.For example,please indicate whether the
cost of any system upgrades were assigned to the bidder,or socialized as a network
upgrade.As part of your answer,on a bid by bid basis,please quantifyany system
upgrades required for each bid to interconnect,indicate if the system upgrade costs would
be paid by the bidder or the Company,and if paid by the Company,indicate how and the
extent to which the costs impacted the cost of the bid project.
Response to WIEC Data Request 12.6
The cost of interconnection network upgrades specific to each project,as applicable,were
accounted for in the bid selections identified by the System Optimizer (SO)model and
subsequently analyzed using the Planning and Risk model (PaR).These interconnection
network upgrade costs are specific to a given bid,and therefore,are included as part of
the project cost for the bid.In this way,bid selections identified by the SO model
account for how a specific bid will contribute to overall costs.The interconnection
network upgrade costs associated with bids selected to the final shortlist will be incurred
by the Company and included in base rates,and the associated revenue requirement will
be partially offset by incremental revenue from other transmission customers (please
refer to page 23 lines 16-23 and page 24 lines 1-14 in the direct testimony of Company
witness,Rick T.Link).
The Company also included the cost of the new transmission project from Aeolus-to-
Bridger/Anticlinetransmission line in the SO model and PaR as a system cost when
evaluating bids located in Wyoming behind the transmission constraint.As with
interconnection network upgrade costs,the cost of the Aeolus-to-Bridger/Anticline
transmission line will be incurred by the Company and included in base rates,and the
associated revenue requirement will be partially offset by incremental revenue from other
transmission customers (please refer to page 23 lines 16-23 and page 24 lines 1-14 in Mr.
Link's direct testimony).
Due to the ongoing nature of the 2017 Renewable Request for Proposals (2017R RFP),
specific bid information associated with the 2017R RFP is considered commercially
sensitive and highly confidential.The Company does not typically permit access to
commercially sensitive 2017R RFP documentationuntil the RFP has been concluded.
