explain the O&M values for that timeframe.
(d)Please explain the O&M values in Attachment 5.2 for 2017 and 2018 in

Response to IIPA Data Request 30
(a)Referencing the Company's responseto IIPA Data Request,specifically
Confidential Attachment IIPA 5-2,as shown in the spreadsheet,there are no
differences between the operations and maintenance (O&M)values for the
years 2017 and 2018 between the cases.
(b)The differences in capital expenditures are due to avoided capital costs
associated with not repairing wind turbine component failures that are not
economic to addressduring the short time prior to repowering in 2019 or
2020.
(c)O&M costs remain relatively constant in 2017 and 2018 since those costs
reflect O&M costs that are contracted under fixed-fee contracts.The
Company will continue to operate and maintain the projects in 2017 and 2018
as it normally would,and thus costs are not impacted until repowering takes
place beginning in 2019.However,the capital costs are reduced in these years
as a result of not investingadditional capital to refurbish and replace
equipment as described above.
(d)O&M amounts for 2017 reflect budgeted amounts,which includes escalation
for contract payments,lease payments,and other budget categories.Expenses
for 2016 and prior years reflect actual expenditures.
