AVISTA CORPORATION
RESPONSE TO REQUEST FOR INFORMATION

JURISDICTION: IDAHO DATE PREPARED: 08/29/2016
CASE NO: AVU-E-16-03 WITNESS: Elizabeth Andrews
REQUESTER: IPUC RESPONDER: Liz Andrews
TYPE: Production Request DEPARTMENT: State & Federal Regulation
REQUEST NO.: Staff - 113 TELEPHONE: [phone]

REQUEST:

Please describe and quantify the impact of using 2016 weather-normalized loads in place of 2015 weather-normalized loads used in this filing. Please include impacts to retail rates, the overall revenue requirement, and net power costs. Please provide all AURORA files and workpapers reflecting the calculations (with formulas intact) using the 2016 loads. Please include non-labor administrative and general, operating and maintenance expenses, and all other relevant expenses in 2016 in the calculation. Note: These expenses were not included in Avista’s Response to Production Request No. 62.

RESPONSE:

Avista has not prepared a study that includes 2016 weather-normalized loads in place of 2015 weather-normalized loads, the impact to retail rates, the overall revenue requirement, net power costs and all other relevant expenses in 2016. This has not been produced and would be unduly burdensome to do so.

For comparison purposes, however, with the weather normalized loads for 2017 used in the Company’s response to Staff_PR_062, the Company is providing the current 2016 weather normalized loads (January - July Weather Normalized Actuals + August - December 2016 Forecast). Please see Staff_PR_113 – Attachment A.
