Avista Reaches Settlement in Washington Electric and Natural Gas Rate Requests

SPOKANE, Wash., Aug. 25 // -- Avista (NYSE: AVA) and all other parties in the company's electric and natural gas rate case filings have reached a settlement agreement that, if approved by the Washington Utilities and Transportation Commission (WUTC), would resolve all issues in the cases and result in an overall electric increase of 7.2 percent in billed rates and a natural gas increase of 3.2 percent in billed rates. New rates would become effective Dec. 1, 2010. Under the terms of the settlement agreement, annual electric revenues would increase by $29.5 million and natural gas annual revenues by $4.6 million.

If the agreement is approved by the WUTC, a residential customer in Washington using an average of 1,000 kilowatt-hours of electricity per month would see a $5.62 per month increase, or 7.8 percent, for a revised monthly bill of $77.41. A residential customer using an average of 69 therms of natural gas per month would see a $2.17 per month increase, or 3.6 percent, for a revised monthly bill of $62.20.

In addition to Avista, the parties to the settlement are the staff of the WUTC, the Public Counsel Section of the Washington Office of the Attorney General, Northwest Industrial Gas Users, Industrial Customers of Northwest Utilities and The Energy Project. The WUTC is not bound by the settlement.

"We believe the settlement agreement represents a fair and reasonable outcome for our customers and for our shareholders," said Dennis Vermillion, Avista Corp. senior vice president and president of Avista Utilities. "The agreement is the result of concessions and compromises on a number of issues to arrive at an outcome that is supported by all parties in the rate filings. It also represents continuing progress in our efforts to timely recover the costs of serving our customers."

Avista's original request filed with the WUTC in March 2010 was for an electric rate increase of 13.4 percent, or $55.3 million in increased annual electric revenues. The difference between the original request and the amount in the settlement agreement is due partly to an $11.7 million decrease in power supply costs, caused primarily by the decline in natural gas fuel prices since Avista's original filing in March.

The settlement is based on an overall rate of return of 7.91 percent with a common equity ratio of 46.5 percent and a 10.2 percent return on equity. Avista's original request was based on an overall rate of return of 8.33 percent with a common equity ratio of 48.4 percent and a 10.9 percent return on equity. These changes reduced the electric revenue requirement by $7.3 million and the natural gas revenue requirement by $1.3 million.

Avista had requested to increase natural gas rates by an average of 6.0 percent, or $8.5 million in additional annual revenue. The decline from the original request to the amount in the settlement agreement is also due in part to additional Jackson Prairie (JP) natural gas storage that will be used in Avista's utility operations beginning May 1, 2011. The actual revenue requirement associated with the new JP natural gas storage inventory would be deferred and recovered through the annual purchased gas adjustment mechanism until the costs are reflected in the next general rate case. This provision reduced Avista's base rate revenue requirement by approximately $1.2 million.

As part of the settlement agreement, Avista would not file a general rate case in Washington before April 1, 2011.

Recognizing the impact of rising prices on customers, especially limited income and senior customers, funding under this settlement for Avista's Low Income Rate Assistance Program (LIRAP) would also be increased by the same percentage as the overall rate increase approved in this case. Total electric LIRAP bill assistance funding would increase to approximately $3.3 million and natural gas funding would increase to $1.7 million. Also, annual funding for low-income energy efficiency programs would increase from $1.5 million to $2.0 million.

Lancaster Plant Cost Deferrals

The parties have agreed that recovery of the deferred net costs associated with the power purchase agreement for the Lancaster Plant for 2010 would be limited to $6.8 million. Avista expects the 2010 net costs to be approximately $12 million.  The net deferred costs of $6.8 million would be recovered over a five-year amortization period with a rate of return on the unamortized balance.  For the six months ended June 30, 2010, Avista had deferred $7.6 million of net costs associated with the Lancaster Plant. The parties agreed that the costs for Lancaster for 2011 and going forward are reasonable and should be recovered in rates.

2010 Energy Recovery Mechanism

As part of the settlement related to the 2010 Lancaster Plant deferrals, the parties have agreed that there would be no deferrals under the Energy Recovery Mechanism (ERM) for 2010 in either the surcharge or rebate direction. Avista Corp. would assume the risk on all costs and benefits in ERM-related power supply costs for 2010.

Avista absorbed $2.8 million of costs under the ERM (within the dead-band) for the six-months ended June 30, 2010, as actual net power supply costs exceeded the amount included in base retail rates. However, by the end of 2010 Avista expects to be in a benefit position under the ERM and into the customer/company sharing bands in the rebate direction, due primarily to lower wholesale electric and natural gas fuel prices than the amount included in retail rates.

Avista estimates ERM deferrals in the rebate direction that would be available to the company to offset all or a portion of the Lancaster deferrals absorbed by the company, to be in the range of $0 to $5 million. The opportunity to be in the upper part of the range will be dependent upon normal hydro-electric generation for the balance of the year, thermal generating plants operating reliably, and a continuation of relatively stable wholesale electric and natural gas prices, among other factors.  In addition, the $0.5 million carry-over balance in the ERM from prior periods in the rebate direction would be recorded as a benefit to the company, such that the total ERM balance at Dec. 31, 2010, would be zero.

The ERM is an accounting mechanism that captures the difference between Avista's actual cost of generating and purchasing power each month, and the cost currently included in customer rates.  Refer to Avista Corp.'s Annual Report on Form 10-K for the year ended Dec. 31, 2009, and Quarterly Report on Form 10-Q for the period ended June 30, 2010, for further details with respect to the ERM.
