The increase in pro forma net 16 expense related to the inclusion of the Lancaster plant is 17 approximately $21.3 million (system) or $7.5 million (Idaho 18 share). With regard to the power contracts, there are four 19 low-cost 25 aMW power purchases that end December 31, 2010. 20 The cost to replace these power purchase agreements 21 increases Idaho expense by $3.6 million.Mr. Johnson 22 discusses each of the increased expenses in detail in his 23 testimony.

JOHNSON DIRECT TESTIMONY (Marked) REVISED APRI 12, 2010 1 the 2009 calendar-year test period and the pro forma period 2 October 2010 to September 2011.The table below shows 3 total net power supply expense during the test period and 4 the pro forma period.For information purposes only, the 5 power supply expensel currently in rates, which is based on 6 a July 2009 through June 2010 pro forma period, is also 7 shown. Idaho System Allocation Power Supply Expense in Current Base Rates $169,037,000 Actual Jan 09 - De 09 Power Supply Expense $189,811,000 Adjustment to Test Period $29,376,000 $10,319,789 Proposed Pro forma Power Supply Expense $219,187,000 Increase frm Expense in Current Rates $50,150,000 $17,617,6958 9 The net effect of my adjustments to the test year 10 power supply expense is an increase of $29,376,000 11 ($219,187,000 - $189,811,000) on a system basis. The Idaho 12 allocation of this adjustment of $10,319,789 is 13 incorporated into the revenue requirement calculation for 14 the Idaho jurisdiction by Company witness Ms. Andrews. 15 The increase in power supply expense compared to the 16 authorized level in current base rates is $50,150,000 17 (system) and $17, 617,695 (Idaho allocation) . 1 For the remainder of my testiony, for puroses of the power supply adjustment, I will refer to the net of power supply revenues and expenses as power supply expense for ease of reference. Johnson, Di 3 Avista Corporation REVISED APRI 12, 2010 1 expiration of a load following contract with NorthWestern 2 Energy along with other contract volume and price changes. 3 Higher fuel prices increases power supply expense by 4 $5.3 million (Idaho allocation). This impact is the sum of 5 higher natural gas fuel prices ($4.1 million) and higher 6 net costs at Colstrip and Kettle Falls ($1. 2 million). 7 Natural gas prices in this pro forma are $6. 26/dth 8 (Stanfield) compared to $4. 79/dth in the current base 9 rates. 10 A reduction in retail loads reduces power supply 11 expense by $2.1 million (Idaho allocation). Pro forma 12 system loads are 13.5 aMW lower than loads that current 13 rates are based on. Most of this increase is mitigated by 14 the production property adjustment so the net impact of 15 lower retail loads is small. 16 The table below shows the primary factors driving the 17 increase in power supply expense compared to the level in 18 current base rates.
