I.P.V.C. No. 27 - Natural Gas Service
Enclosed for filing with the Commssion is the following revised tarff sheet:
Ninth Revision Sheet 155 canceling Eighth Revision Sheet 155
This fiing proposes to decrease rates for the Company's Idaho natural gas customers by
approximately 6.0 cents per therm, or about 4.7% for residential and small commercial
(Schedule 101) customers. Larger-use customers served under Schedule 111 would see
an average decrease of 5.4%. The Company requests that the proposed tarff change be
made effective on January 6,2009, under modified procedure with less than statutory
notice.
Since the Company's 2008 PGA filing, dated September 12th, wholesale natural gas
prices have continued to fall, even below projected prices included in that filing. As a
result of lower-cost gas purchases over the past several months, deferred gas costs due
customers have grown significantly since the PGA filing. This filing proposes to adjust
the amortization rate(s) to refund additional deferred amounts to customers from Januar
through October 2009. The Company is not proposing to change the WACOG approved
in the September 2008 PGA filng.
With the present state of the economy and customers experiencing higher winter heating
bils, the Company believes that it is appropriate to reduce natural gas rates at this time.
While the Company could support a larger decrease in this filng, itisalso concerned
about rate volatilty in the future, i.e., a larger decrease now could increase the possibilty
of a PGA increase in the fall of 2009.
The proposed amortization rate included in this fiing is a refund rate of approximately
7.7 cents per therm, reflecting a 6.0 cents per therm decrease compared to the present
amortization (refund) rate of 1.7 per thermo The proposed amortization rate would refund
to customers approximately $4.0 milion by October 31,2009, based on projected
customer usage. This amount reflects 72% of the deferral balance of $5.6 millon at the
end of November 2008. Refunding the entire $5.6 millon would result in a refund rate of
approximately ten cents per therm and, again, would increase the possibilty of an
increase in the 2009 PGA filng.
The proposed decrease would result in a monthly bil reduction of $3.89 for a residential
customer using an average of 65 therms per month, from a present bil of $82.12 to
$78.23 per month. The Company wil issue a media release coincident with this filng. If
the proposed decrease is approved, the Company wil include a message on customer bils
informng them of the decrease.
Also enclosed is a copy of the media release and the workpapers supporting the proposed
decrease.
If you have any questions regarding this filng, please contact Brian Hirschkorn at (509)
495-4723 of Craig Bertholf at [phone].
Sincerely,
