SUBJECT: IDAHO POWER’S TARIFF ADVICE NO. 12-13

On November 28, 2012, Idaho Power Company filed Tariff Advice No. 12-13 with
the Commission seeking authority to update Schedule 89 with an effective date of January 1,
2012. Pursuant to Rule 134.02 of the Commission’s Rules of Procedure, a “tariff advice not
suspended or approved goes into effect thirty (30) days after filing or on the proposed effective
date, whichever is later.”
THE TARIFF ADVICE
Based on previous Commission Order, the pricing under Schedule 89 is to be
adjusted as a result of an Idaho Power general rate case proceeding where net power supply
expenses change. Due to extenuating circumstances, Schedule 89 was not updated as part of the
Company’s original general rate case compliance filing on December 30, 2011.
Upon the Company’s review of Schedule 89 and what triggers its update, the
Company has concluded that, while the separate events of (1) an update to NPSE and (2) the
occurrence of a general rate case proceeding did not occur simultaneously as they had
historically, the combined effect of the consecutive occurrences of these individual events had
the same effect. Therefore, the Company proposes to update Schedule 89 as if it were part of the
Company’s original compliance filing on December 30, 2011, with an effective date of January
1, 2012.
DECISION MEMORANDUM 2
STAFF RECOMMENDATION
Staff has reviewed the filing and recommends that, based on the backdated nature of
the request and the potential impact on customers, the tariff advice be suspended and the case
proceed by Modified Procedure. Idaho Power does not oppose Staff’s recommendation.
COMMISSION DECISION
Does the Commission wish to suspend Tariff Advice No. 12-13 and process the case
by Modified Procedure?
