ITEM 8.01      OTHER EVENTS

General Rate Case Filing

On June 27, 2008, Idaho Power Company (Company) filed a general rate case with the Idaho Public Utilities Commission (IPUC) based on a forecast 2008 test year to increase the Company's base rate for electricity an average of 9.9 percent for its Idaho customers.  If approved, Company revenues would increase approximately $67 million annually.  The Company requested that the rate increase be effective February 1, 2009.  The Company is unable to predict what relief the IPUC will grant.

A copy of the press release related to this filing is furnished as Exhibit 99.1 hereto.

Power Cost Adjustment

On May 30, 2008, the Idaho Public Utilities Commission (IPUC) approved the IPUC staff's recommendation for monthly allocation of the base net power supply costs included in the 2007 general rate case.  The adopted allocation was effective March 1, 2008, and results in an even monthly distribution of base net power supply costs used in the calculation of the Idaho Power Cost Adjustment (PCA) deferral.  The Company had requested a moderate seasonal distribution for base net power supply costs.  This matter was previously reported in the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on June 4, 2008.

While the distribution methodology utilized does not affect the total amount of base net power supply costs used to calculate the PCA deferral, it does affect the quarters in which they are allocated.

As a result of the 2007 general rate case, $127.5 million of net power supply costs have been included in base rates beginning March 1, 2008.  After adjusting for the Idaho jurisdictional split and recognizing the 90/10 sharing between customers and shareowners, base net power supply costs used in the PCA deferral calculation are approximately $117.5 million.  The following table compares the quarterly estimated pre-tax impact of the two methodologies:

2

		Base Net Power Supply Costs
		March 1, 2008 through February 28, 2009
		($ amounts in millions)
		2008		2008		2008		2008			2009
		First		Second		Third		Fourth			First
		Quarter		Quarter		Quarter		Quarter			Quarter				Total
PCA Base (seasonal distribution)		$	3.3	$	26.6	$	46.4	$	29.6	$		11.6	$	117.5
PCA Base (even distribution)			9.7		29.4		29.4		29.4			19.6		117.5
PCA Expense increase/(decrease)		$	6.4(1)	$	2.8	$	(17.0)	$	(0.2)	$		8.0	$	0.0
(1)  Due to the IPUC's approval of the even monthly distribution of base net power supply costs on May
	30, 2008 with an effective date of March 1, 2008, the Company will recognize an additional $6.4
	million of PCA expense related to the March 2008 time period in the second quarter 2008.

In 2008, the Company will participate in PCA Workshops that will address the future distribution of base net power supply costs along with other PCA matters.  The Company expects the distribution issue to be resolved as a result of the workshop proceedings.  Until such time as a final PCA base distribution methodology is implemented, the quarterly results will be subject to variability and may experience significant shifts from one quarter to another as compared to historical results; however, the total impact from any distribution methodology should be zero within a twelve month period that base net power supply expenses are collected.

Pacific Northwest Refund

As previously reported in our annual report on Form 10-K for the year ended December 31, 2007 and quarterly report on Form 10-Q for the quarter ended March 31, 2008, the United States Court of Appeals for the Ninth Circuit (Ninth Circuit), on review of FERC orders dealing with certain long-term power contracts, considered the 50-year-old Mobile-Sierra contract-finality doctrine.  The premise of the Mobile-Sierra doctrine is that the Federal Power Act and the Natural Gas Act presume the justness and reasonableness of rates negotiated by private parties at arm's length and do not sanction the Federal Energy Regulatory Commission's (FERC) modification of such rates unless the terms of the contract threaten the "public interest" or the contract expressly allows for it.

On June 26, 2008, in Morgan Stanley Capital Group Inc. v. Public Utility District No. 1 of Snohomish County (No. 06-1457) (Snohomish), the U.S. Supreme Court (Court) revisited and clarified the Mobile-Sierra doctrine in the context of fixed-rate, forward power contracts.  At issue was whether, and under what circumstances, the FERC could modify the rates in such contracts on the grounds that there was a dysfunctional market at the time the contracts were executed.  In its decision, the Court disagreed with many of the conclusions reached by the Ninth Circuit and upheld the application of the Mobile-Sierra doctrine even in cases in which it is alleged that the markets were dysfunctional.  The Court nonetheless returned the case to the FERC to (i) consider whether the challenged rates in the case constituted an excessive burden on consumers either at the time the contracts were formed or during the term of the contracts relative to the rates that could have been obtained after elimination of the dysfunctional market and (ii) clarify whether it found the evidence inadequate to support a claim that one of the parties to a contract under consideration engaged in unlawful market manipulation that altered the playing field for the particular contract negotiations - that is, clarify whether there was a causal connection between allegedly unlawful activity and the contract rate.

Neither the Company nor IDACORP Energy (IE), a subsidiary of IDACORP, Inc., had contracts that were challenged in Snohomish, but the decision is expected to have general implications for contracts in the wholesale electric markets regulated by the FERC, and particular implications for forward power contracts in such markets.  The Snohomish decision upholds the application of the Mobile-Sierra doctrine to fixed-rate, forward power contracts even in allegedly dysfunctional markets.  The Company and IE have asserted the Mobile-Sierra doctrine as a defense to the claims asserted in the Pacific Northwest proceeding involving spot market contracts in an allegedly dysfunctional market.  IDACORP, Inc. and the Company are unable to predict how the FERC will rule on Snohomish on remand or how this decision will affect the outcome of the Pacific Northwest proceeding.

Idaho Power Files General Rate Case Increase Request

BOISE-IDACORP, Inc.'s (NYSE:IDA) principal subsidiary Idaho Power Company (Company) today filed an application with the Idaho Public Utilities Commission (IPUC) to increase the Company's base rate for electricity an average of 9.9 percent for its Idaho customers. If approved, Company revenues would increase $67 million annually. The IPUC now has seven months to consider the Company's request.

"Two forces are driving this increase; growth in the number of customers and a growing demand for electricity," said Idaho Power Vice President for Regulatory Affairs Ric Gale.  "We have invested heavily to ensure we can provide a safe and dependable supply of energy for our current and future customers.  This request seeks to recover those investments."

Since 2005, the Company has invested $578 million in its electrical system.  This includes construction of 13 new substations, adding 1,157 pole-miles of distribution line, and 190 pole-miles of transmission lines.

Operating and maintenance expenses have also increased over the period driven by increased levels of power purchases, continued customer growth and inflation.
