Analyst · the day for a period of 12 months on the company's website at www.idacorpinc.com
Thanks, Larry, and good afternoon, everyone. I will begin by reviewing the results for the quarter and update you on the key operating and financial metrics. Steve will discuss our liquidity and financing activities for 2012, and then LaMont will discuss the completion of Langley Gulch and other business-related matters. We will then stand for your questions.
On Slide 5, we present a reconciliation of net income attributable to IDACORP from the second quarter of 2011 to the second quarter of 2012. This reflects an increase in net income of $14.4 million. The full reconciliation table is included in the Form 10-Q we filed this morning.
Operating income was positively impacted by $5.8 million due to timely recovery of revenue requirements through base rates and adjustment mechanisms. Warmer-than-normal temperatures and below-normal precipitation led to a $19.5 million increase in operating revenues compared with last year's second quarter.
While irrigation sales during the second quarter of 2011 were below historic averages, sales to this customer group in the second quarter of 2012 were near historic highs. Irrigation usage for the second quarter was the third highest in over 10 years.
Cooling degree days in the second quarter this year were 134% greater than the same period last year and nearly 9% greater than normal. Precipitation levels were generally lower throughout Idaho Power's service territory, and this, too, contributed to greater energy demand for operation of irrigation systems.
Pension-related expenses reduced operating income by $2 million, while the combination of changes in other O&M, depreciation, property tax, changes in earnings at Bridger Coal Company and an increase in allowance for funds used during construction, or AFUDC, increased operating income by $6.7 million compared with second quarter 2011.
Idaho Power did not record additional accumulated deferred investment tax credits, or ADITC, in the second quarter of 2012 and reversed the $800,000 recorded in the first quarter this year. This resulted in $3.7 million reduction to net income quarter-over-quarter since amortization of additional ADITC was still anticipated and being recorded in the second quarter of 2011.
Finally, higher pretax earnings resulted in greater income tax expense and, when combined with other net decreases, resulted in a net income reduction of $11.9 million.
Idaho Power does not expect to use additional ADITCs in the Idaho jurisdiction in 2012, and this is reflected on Slide 6. While subject to a number of factors, including those outlined in the Form 10-Q we filed today, Idaho Power's year-end return on equity in the Idaho jurisdiction is now expected to exceed 9.5%, which results in no utilization of additional ADITC.
As indicated on Slide 7, we list the changes in our key operating and financial metrics guidance from those discussed last May.
We have been able to tighten the range of expected Idaho Power capital expenditures to between $230 million and $235 million and the estimated hydroelectric generation range to 7.5 million to 8.5 million megawatt-hours. As a reminder, the annual median hydroelectric generation is 8.6 million megawatt-hours.
As discussed in our Form 10-Q, we continue to expect to invest between $490 million and $500 million in capital expenditures for the 2-year period of 2013 and 2014. These amounts are generally for care and feeding of our existing infrastructure and, on a net basis, are expected to grow rate base over the period.
Based on these assumptions and the positive impact of our second quarter results, we are increasing our 2012 full year IDACORP earnings per share guidance from the range of $3 to $3.15 per diluted share to the range of $3.20 to $3.35 per diluted share. Should we reach the upper end of our earnings range, we would expect to exceed the earnings deadband in the Idaho jurisdiction as prescribed by our agreement with the Idaho Public Utilities Commission, resulting in a portion of our earnings being shared with customers.
As discussed in our 2011 10-K and in the 10-Qs we filed this year, recall that our earnings results are seasonal and that utility revenues and expenses are not incurred evenly during the year. Our tiered rate structure impacts earnings recognition between quarters, as revenues during high or low periods may be influenced by higher seasonal rates.
Now turning to a couple of operating matters. First, I'd like to update you on one of our large industrial customers. Back in March 2012, the Idaho Public Utility Commission approved a stipulation to amend the electric service agreement between Hoku and Idaho Power. However, as a result of Hoku's failure to remain timely in payments under the revised agreement, Idaho Power terminated its provision of electric service under the primary industrial contract in May 2012. Idaho Power applied the remaining $2 million deposit then on hand to Hoku's April and May invoices and a portion of June's invoice. The anticipated negative revenue and earnings impacts from termination of service to Hoku have been factored in to our updated earnings guidance.
Now I'd like to update you on the current status of the Boardman to Hemingway transmission line. As discussed in our 2011 Integrated Resource Plan, the line is a proposed 300-mile, 500 KV transmission project between a station near Boardman, Oregon and Hemingway station near Boise, Idaho. Through a joint funding agreement between Idaho Power, PacifiCorp and the Bonneville Power Administration, Idaho Power's expected share of the permitting phase is approximately 21%, and we would seek that same percentage interest in the completed project. Based on the execution of the terms of the joint funding agreement, Idaho Power's estimated share of the cost of the permitting phase of the project is $11 million and we currently estimate the total project cost to be approximately $820 million, both amounts include AFUDC.
While the 2011 Integrated Resource Plan provided for a mid-2016 in-service date for the line, we are now estimating that an in-service date prior to 2018 is unlikely. As we continue to work through the permitting and siting process with our partners, challenges remain. These include, but aren't limited to: coordination of efforts between state and federal agencies; environmental considerations, including changing regulations around staged route [ph]; as well as ongoing public outreach. These challenges have combined to force the extension of the proposed in-service date. We continue to work closely with the state and federal permitting agencies, as well as the federal rapid response team in working through the process and welcome their participation.
The next major milestone for the project in the federal permitting process will be the draft environmental impact statement that is due out in the first half of 2013, where we expect to see an agency preferred line route proposal coming from the Bureau of Land Management. We plan to evaluate the impact of the new in-service date in the upcoming 2013 Integrated Resource Plan.
Steve will now discuss IDACORP's 2012 liquidity position and the 2012 expected debt and equity financing requirements.
