IDACORP Announces Second Quarter 2006 Results

Second Quarter 2006 Highlights

Second quarter 2006 diluted earnings per share of $0.47 versus $0.22 in 2005

Idaho Power records $17 million increase in operating income

Hydroelectric generation increases 56 percent over last year

Idaho Power records $4.7 million after-tax benefit from sale of excess emission allowances

BOISE-IDACORP, Inc. (NYSE:IDA) today reported second quarter income of $19.9 million versus $9.5 million in 2005 and year-to-date earnings of $45.3 million compared with $32.5 million in 2005. Diluted earnings per share increased by $0.25 per share for the quarter to $0.47 per share and by $0.29 per share for the first six months to $1.06 per share.

"Increased loads as a result of warmer-than-normal temperatures, improved water conditions, and higher irrigation demand helped lift earnings over last year," said IDACORP President and Chief Executive Officer J. LaMont Keen. "In addition, second quarter results benefited from the sale of excess emission allowances."

On August 1, the Northwest River Forecast Center (NWRFC) reported 9.0 million acre-feet (maf) of water flowed into Brownlee Reservoir during the April-through-July 2006 period. The NWRFC's 30-year average measured inflow into Brownlee is 6.3 maf during the period. In 2005, April-July inflows were 3.6 maf.

Second Quarter Performance Summary

The following are key components of the change in second quarter IDACORP net income from 2005 to 2006.

Enhanced hydroelectric generating conditions factored heavily into Idaho Power's improved performance. Second quarter 2006 hydro generation was 56 percent higher than second quarter 2005. This additional hydro generation significantly reduced net power supply costs providing a seven-cents-per-diluted-share benefit, quarter-over-quarter.

General business revenues increased $8.6 million from last year's second quarter. Idaho Power's increase in general business revenues reflects the continuing growth in general business customers, warmer temperatures and two general rate increases. On June 1, 2005, annual Idaho general business rates increased 1.8 percent ($9.4 million) and on June 1, 2006, those annual customer rates increased an additional 3.2 percent ($18.1 million).

Average energy use increased in the residential and irrigation customer classes. This is highlighted by irrigation energy sales which increased 64 percent over the levels reported in the abnormally cool and wet second quarter of 2005.

Idaho Power recorded a benefit of $4.7 million after tax from the sale of excess emission allowances in accordance with a regulatory order from the Idaho Public Utilities Commission (IPUC).

On June 1, 2006, annual Idaho retail rates decreased by an average of 19.3 percent as the result of the Power Cost Adjustment (PCA). The company projects the PCA reduction will decrease the company's revenues approximately $123 million during the period June 1, 2006 through May 31, 2007.
