IDACORP, Inc. Announces Year-End and Fourth Quarter 2012 Results,

Initiates 2013 Earnings Guidance

BOISE--IDACORP, Inc. (NYSE: IDA) reported 2012 net income attributable to IDACORP of $168.8 million, or $3.37 per diluted share, compared to $166.7 million, or $3.36 per diluted share, in 2011. IDACORP reported fourth quarter 2012 net income attributable to IDACORP of $16.5 million, or $0.33 per diluted share, compared to $9.0 million, or $0.18 per diluted share, in the fourth quarter of 2011. IDACORP's 2013 full year earnings guidance is in the range of $3.20 to $3.35 per diluted share.

Idaho Power Company, IDACORP's principal subsidiary, reported 2012 net income of $168.2 million compared to $164.8 million in 2011, and net income of $18.0 million in the fourth quarter of 2012 compared to $9.3 million for the same period in 2011.

“In recent years we have focused heavily on advancing Idaho Power's three-part strategy of responsible planning, responsible development and protection of resources, and responsible energy use to ensure adequate energy supplies,” said IDACORP, Inc. President and CEO J. LaMont Keen. “This focus resulted in significant regulatory, operational, and financial success in 2012, without the need to amortize additional accumulated deferred investment tax credits, or ADITCs, available under an Idaho regulatory settlement agreement. Our solid financial performance also allowed Idaho Power to share $21.8 million of benefits with Idaho customers in 2012 for the second consecutive year.”

“We believe our recent achievements position us well going into 2013 and beyond, and at this time we expect minimal use of additional ADITCs in 2013. The ADITC-related provisions of the settlement agreement also are expected to provide us with an element of earnings stability through 2014 as we continue to execute on our strategy. We plan to advance a number of important initiatives in 2013, including infrastructure projects and new technology solutions, and taking steps to further our dividend policy,” added Keen.

Net income attributable to IDACORP, Inc. - December 31, 2012					$	168.8

IDACORP's net income was $168.8 million in 2012, an increase of $2.1 million over 2011. IDACORP's 2012 results reflect an $86.3 million increase in operating income at Idaho Power compared to 2011, which was largely driven by increases in rates and higher irrigation sales volumes. This increase was substantially offset by the net impact of a tax method change and favorable IRS examination settlements recorded in 2011.

General rate increases implemented in the first quarter of 2012, a July 2012 rate increase related to Idaho Power's new Langley Gulch power plant, and other rate changes combined to increase operating income by $65.2 million when compared to 2011. Higher sales volumes, driven primarily by a warmer, drier spring in 2012 that caused significant increases in irrigation usage when compared with the prior year, increased operating income by $16.1 million. As a result of an Internal Revenue Service (IRS) examination settlement reached in 2011, Idaho Power recognized approximately $56.9 million of previously unrecognized tax benefits related to the uniform capitalization method agreement with the IRS for tax years 2009 and prior.

As a result of the impact on 2012 earnings of the rate and sales volume increases described above, Idaho Power recorded a total charge of $21.8 million related to a December 2011 settlement agreement with the Idaho Public Utilities Commission (IPUC), which required sharing with customers a portion of 2012 Idaho-jurisdiction earnings exceeding a specified return on year-end equity. Of the total, $14.6 million was recorded as additional pension expense, which will benefit Idaho customers by reducing the amount of deferred pension expense that will need to be collected from customers in the future, and $7.2 million was a provision against current revenues to be refunded to customers through a future rate reduction. In 2011, Idaho Power recorded $20.3 million of additional pension expense and a $27.1 million provision against revenues to be refunded to customers under similar agreements. The table below summarizes the effect of the sharing mechanisms on operating income between 2012 and 2011.

Effect of Sharing on Operating Income
	2012			2011			Variance
Provision against current revenue as a result of sharing	$	(7.2	)	$	(27.1	)	$	19.9
Additional pension expense funded through sharing	(14.6		)	(20.3		)	5.7
Total	$	(21.8	)	$	(47.4	)	$	25.6
