Industry Update
• On February 7, 2013, the National Oceanic and Atmospheric Administration (NOAA) issued its February
Forecast for 2013 water supply for the Northwest United States. In general, water supply conditions have
declined since last month and are below-to-near normal with less precipitation in recent months following above-
average precipitation in October 2012. According to the NOAA, 2013 water supply forecasts at the Columbia - Dalles Dam are 92% of normal based on the 30-year average. See Table 1 for water supply data and Table 2
for runoff data. See Table 7 for Mid-C spot power prices.
• Within the Ladenburg Thalmann utility universe (and in order of sensitivity to changes in hydro conditions),
Portland General Electric (POR-$28.48-NEUTRAL), Avista Corp (AVA-$26.04-NEUTRAL), and IDACORP (IDA-$46.45-BUY) are the companies primarily affected by these reports as their generation portfolios all contain
substantial hydroelectric assets.
• As of February 7, 2013, forecast stations St. Regis, Near Plains and Cabinet Gorge Dam along the Clark Fork
River are forecasted to have water supplies 86%, 86%, and 90% respectively, of their 30-year averages. The Spokane forecast station in Spokane and Coeur D’Alene Lake in northern Idaho, primary outflow is the Spokane
River, are forecasted to have water supplies 91% and 85% of their 30-year averages, respectively. AVA’s
hydroelectric generating facilities are located along the Clark Fork River (~80% or 794 MW) in Idaho and
Montana and the Spokane River (~20% or 180 MW) in Washington. See Table 3 and Table 4.
• Brownlee and Hells Canyon, IDA’s largest hydroelectric generation facility, are forecasted to have water
supplies 75% and 74% of their 30-year averages, respectively. IDA’s hydroelectric facilities are primarily
located on the Snake River along the Idaho/Oregon border. See Table 5.
• The Estacada forecasting station along the Clackamas River is forecasted to be 101% of its average. POR’s wholly-owned hydro facilities (~190MW) are located on the Clackamas River in northern Oregon, and POR’s
jointly-owned facilities (66.7% ownership in ~300MW) are on the Deschutes River in Oregon. POR’s also has
long-term purchase power contracts for output of 4 hydroelectric projects in the mid-Columbia River totaling 507
MW and a long-term agreement for output of the Pelton/Round Butte hydroelectric project totaling 150 MW.
See Table 6.

Table 9: Sharing Mechanism Description
Avista Corp
Under the Energy Recovery Mechanism (ERM), there is a 50% customer sharing when
actual power supply expenses are higher than the amount between $4-$10m, there is a
75% customer sharing when actual power supply expenses are lower (rebate to customer)
than the amount included in base rates between $4-$10m, AVA receives 100% of the cost
or benefit within the $4m “deadband”, and 10% of the cost variance when power supply
costs exceed $10m.
Idacorp
Any shortfall (as compared with the median) is generally replaced with purchase power from
the open markets and 95% of those costs are recovered through the PCA mechanism in
Idaho. IDA was authorized by the Idaho Public Utility Commission (IPUC) in January 2009
to change its sharing mechanism to 95/5 (previously 90/10 sharing with customers), as well
as, the implementation of a forward-looking model forecasting fuel costs.
Portland General
POR utilizes a Power Cost Adjustment Mechanism (PCAM) to adjust rates to reflect
differences between forecast and actual power costs. The PCAM deadband range is from
$15m below to $30m above the baseline of net variable power costs. Amounts above or
below the deadband are shared with customers/shareholders 90/10. An earnings test is
also conducted that further mitigates cost pressures with customer surcharge if actual ROE
is no greater than 9.0% and customer refund if actual ROE is no less than 11.0%.

APPENDIX A: IMPORTANT RESEARCH DISCLOSURES

ANALYST CERTIFICATION
I, Brian Russo, attest that the views expressed in this research report accurately reflect my personal views about the subject security

Rising fuel costs could adversely impact financial performance. High and volatile supply costs could negatively impact near-term
results.
Complex utility regulation which could adversely affect the Companies’ results of operations, financial position and cash flows.
The outcome of retail rate proceedings which could have a material impact on the business and is largely outside the Companies’
control.
Current and potential environmental requirements and the incurrence of environmental liabilities, any or all of which may adversely
affect the business and financial results.
Weather variations and demand fluctuations can directly impact results of operations.
STOCK RATING DEFINITIONS
