RE: Case No. GNR-E-ll-04
Pursuant to the Public Utility Regulatory Policies Act -of 1978 (PURP A) and the implementing
regulations of the Federal Energy Regulatory Commission (FERC), the Idaho Public Utilities
Commission (Commission) has approved a Surogate Avoided Resource (SAR) methodology for
calculation of the avoided cost rates paid to PURP A qualifying cogeneration and small power
production facilities (QFs) by Idaho Power Company, Avista and PacifiCorp. Avoided cost rates
are the purchase price paid to QFs for purchases of QF capacity and energy.
One of the key input variables in the computation of avoided cost rates is a long-term natural gas
price forecast. In accordance with the methodology approved in Order No. 29124, the medium
natural gas price forecast of the Northwest Power and Conservation Council (NPCC; Council) is

to be used as the basis for computing avoided cost rates. In Order No. 29124, the Commission
also found that the release of a new fuel price forecast by the Council or the Council's general
advisory committees automatically triggers a recalculation of the published avoided cost rates.
A new Council natural gas price forecast was approved on August 9, 2011. The forecast was
posted on the Council's website on August 12, 2011. The forecast amends Appendix A to the
Plan. A copy of the amended medium natural gas price forecast is attched. In accordance with
the approved methodology, east-side delivered prices are to be used for avoided cost
computations.
Commission Staff has recomputed avoided cost rates using the Council's most recent gas price
forecast. Accompanying this letter are sheets showing the results from recomputation of the
avoided cost rates using the new Council natural gas price forecast that was posted on August 12,
2011. If after reviewing the revised rates, you accept them as accurate please indicate your
approval by letter (or other fiing) directed to the Commission in the reserved case docket
numbers identified above. The case heading for the adjustment, Case No, GNR-E-11-04, wil
read as follows:
IN THE MATTER OF THE ADJUSTMENT OF AVOIDED COST RATES FOR
NEW PURPA CONTRACTS FOR AVISTA CORPORATION DBA AVISTA
UTILITIES, IDAHO POWER COMPANY, AND PACIFICORP DBA ROCKY
MOUNTAIN POWER.
Please fie your respective responses with the Commission on or prior to August 23, 2011.
Than you for your cooperation. Please feel free to contact me or Rick Sterling if you have any
questions.

Update to the Council's Forecast of Fuel Prices
The Council monitors its power planning assumptions on a regular basis to identify any
significant changes that might affect its Sixth Power Plan, and the action plan also calls for a
biennial monitoring report (MON-I) and a mid-term check on conservation savings (CONS-16).
This report reflects the proposed changes in the Council's long-term fuel price forecast. It is often
difficult to distinguish short-term variations in fuel prices, which are expected and modeled in the
Council's planning, from significant long-term changes that can fundamentally alter the whole
range of future expectations. This rarely happens. However, changes in the outlook for natural
gas supplies in the last year appear to signal a fundamental shift in expectations about future
natural gas supplies. Cost-effective technologies to obtain natural gas trapped in shale formations
has changed the view of natural gas supplies from declining and constrained (as forecast in the
Sixth Power Plan) to plentiful and adequate for many decades to come. Although the potential of
shale gas was identified in the plan, the expected cost of developing it has been reduced through
technological breakthroughs so that future costs and prices are now lower.
After working with the Natural Gas Advisory Committee, the Council is proposing a downward
revision of our range of fuel price forecasts. A range of forecasts recognizes continued
uncertinty about developing shale gas--its costs and environmental effects--as well as the speed
of the economic recovery.
Natural Gas Price Forecast Revision
The range of natural gas prices is significantly narrower and lower in the near term compared to
the Sixth Power Plan's forecast. The rapid development of shale gas has created a glut of natural
gas that is likely to last for several years and depress prices. By the end of the forecast horizon in
2030, the forecast reflects a range of possible long-term equilibrium natural gas prices. The
revised medium forecast is about equal to the medium-low forecast in the Sixth Plan at $6.44 in
2010 constant dollars. The revised high forecast is a little above the medium-high, and the low
revised forecast is a little less than $1 below the low case.
The range of forecasts reflects the different views of supply and demand for natural gas. The high
price forecast might be consistent, for example, with a rapid economic recovery in the U.S. and
worldwide, environmental restrctions on shale gas development, aggressive regulation ,Of carbon
emissions leading to more substitution of natural gas electrcity generation for coal, increased use
of natural gas vehicles, increased demand for exports of LNG from Canada and United States, and
increased demand from gas-to-1iquid projects. In contrast, the low forecast would be consistent

with conditions that limit the demand for natural gas and promote the rapid development of
supply.
Implications of Revised Natural Gas Price Forecasts
The likely effect of the revised fuel price forecast on a revised power plan reduces the forecast of
electrcity prices, and to some degree, changes the inter-fuel competition between natural gas and
electrcity. The Council doesn't expect significant effects on the resource strategy from this
change, but that wil be tested at mid-term. Natural gas generation is already the fall-back
resource in the plan, renewables are limited by RPS requirements, and efficiency was constrained
by the assumed rates of penetration and development.
The following figures compare the Sixth Power Plan's forecast with the revised forecast. The
revised forecast reflects lower natural gas prices.

Oil Price Forecast Revision
The range of world oil price forecasts has not been revised as significantly as natural gas prices.
In spite of the changes in natural gas supply and prices, oil prices have remained high, causing a
significant disconnection between oil and natural gas prices. Although the Council assumed that
natural gas prices would remain below oil prices on a Btu basis, the gap has widened and the
proposed revision maintains the wider gap in the future, though reduced somewhat from current
levels.
World oil prices have little effect on the Council's power plan because oil has, to a large degree,
been relegated to a transportation fuel in the U.S. The primary effect might be on electrc vehicle
development, but that is largely determined by other factors relating to technology, consumer
acceptance, and infrastrcture development.

Coal Price Forecast Revision
Like oil, coal prices have relatively little effect on the Council's power plan. They can affect
electrcity market prices in relatively few hours and they affect the operating cost of existing coal-
fired power plants. However, new coal development is pre-empted in much of the region and
new plants do not appear in the Council's plan.
The primary change in the forecast is incorporating 2010 actual prices and narrowing the near-
term range. The long-term forecasts for 2030 are unchanged. Unlike the natural gas price
forecasts, neither the oil nor the coal price forecasts are used extensively in the region.
