e n-E SUPPLEMENTAL TESTIMONY OF TOBEY L. WINTERS ON STAFF UPDATE OF SKAGIT COSTS TO REFLECT SCHEDULE CHANGES The staff has updated previous estimates of Skagit nuclear costs in Table 1 due to the revision in applicant's schedule and costs.
Previous estimates of cost compari-sons (which are also shown in Table 1) showed close agreement between thb applicant's and staff's costs both in the original submission in 1977 (reflected in Table 2-2, Supplemental Testimony of Tobey L. Winters, Cost-Benefit Analysis) and the update in 1978 (reflected in applicant's answer to Interrogatory No. 7, January 6, 1978).
The staff has updated these costs again to reflect the applicant's testimony on Financial Qualifications dated 1 June 1979. The format for this latter submission is different than previous submissions by the applicant. For consistency, the staff has adjusted the applicant's finaricial data to reflect (1) scope changes; (2) esca-lation on new scope; (3) change from 1978 to 1979 dollars; and (4) increased escalation due to an 18-month rather 12-month schedule change. These changes were added to previous estimates of escalation and Allowance for Funds Used During Construction (AFDC).
The old staff estimates were then updated to reflect the same inflation and escalation factors of 6% and 7% based on previous staff estimates of escalation and capital.
The j
staff estimates of AFDC were retained, but applicant scope changes were added to the staft h previous estimates. With these adjustments, the staff finds that the appli-cant's estimates of costs are again in close agreement with staff's independent estimates and are, therefore, reasonable.
e Consequently, based on the staff's update of fuel (14.5 mills /kWh) and the appli-a cant's update of capital (40 mills /kWh), the staff now estimates the cost of Skagit x
at 54.5 mills /kWh.
This compares with the staff's estimate in 1977 of between 43 1
'^
to 46 mills /kWh and our estimate in 1978 of between 44 to 47 mills /kWh.
