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 Contracts & Administrative Law Division, Idaho Public Utilties Commission P,O, Box 83720, Boise. Idaho 83720-0074, Telephone: (208) 334-0300, FAX: (208) 334-3762, E-mail: IpucC1puc.state.id.us Located at 472 West Washington St, Boise, Idaho 83702 August 16, 2011 Page 2 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.

Bil Booth Idaho Northwest Power and Conservation Council Joan M. DukesVice-Chair Oregon Bruce A. Measure Chair Montana Rhonda Whiting Montana Bil Bradbury Oregon Tom Karier Washington James A. Yost Idaho Phil Rockefeller Washington August 10th, 2011 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 85 i S. W.

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.

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. 2 Comparison of Revised and Sixth Plan Oil Price Forecasts Refiners Acquisition Cost $2010/barrel 140 120 11 100 ..II :;80.. l!.l 600c~""..40 20 -Proposed Low - Proposed Mod Low -Proposed Medium -Proposed Mod.

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.
