BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
IN THE MATTER OF THE APPLICATION
OF IDAHO POWER COMPANY FOR
APPROVAL OF A FIRM ENERGY SALES
AGREEMENT FOR THE SALE AND
PURCHASE OF ELECTRIC ENERGY
BETWEEN IDAHO POWER COMPANY
AND THOUSAND SPRINGS WIND PARK
LLC.
CASE NO. IPC-05-
ORDER NO. 29770
On February 24, 2005 , Idaho Power Company (Idaho Power; Company) filed an
Application with the Idaho Public Utilities Commission (Commission) requesting approval of a
Firm Energy Sales Agreement (Agreement) between Idaho Power and Thousand Springs Wind
Park, LLC (Thousand Springs) dated February 18 2005. Under the Agreement, Thousand Springs
will sell and Idaho Power will purchase electric energy generated by the Thousand Springs Project
located near Hagerman, Idaho in an area more particularly described as Sections 4, 5 , 8, and 9
Township 7 South, Range 13 East, Boise Meridian, Twin Falls County, Idaho and Sections 19 and
, Township 6 South, Range 13 East, Boise Meridian, Twin Falls County, Idaho. The Project
consists of seven (7) 1.5 MW GE wind turbines. The nameplate rating of the project is 10.5 MW.
Under normal and/or average conditions the project will not exceed 10 aMW on a monthly basis.
If energy in excess of this amount (Inadvertent Energy) is accidentally generated, Idaho Power
will accept Inadvertent Energy that does not exceed the 10.5 MW maximum capacity amount but
will not purchase or pay for it. Agreement ~ 7.
The Thousands Springs Project will be a qualified small power production facility (QF)
under the applicable provisions of the Public Utility Regulatory Policies Act of 1978 (PURP A).
As represented by Idaho Power, the Agreement with Thousand Springs comports with the terms
and conditions of Commission Order No. 29632 (Us. Geothermal et al. v. Idaho Power) and
avoided cost Order No. 29646. The contract is for a 20-year term and contains the published non-
levelized avoided cost rates set forth in Order No. 29646. Thousand Springs has selected
December 31 , 2005 as the scheduled operation date and January 15, 2006 as the first energy date.
The proposed effective date of the Agreement is February 18 2005.
ORDER NO. 29770
On March 15, 2005 , the Commission issued Notices of Application and Modified
Procedure in Case No. IPC-05-6. The deadline for filing written comments was Tuesday, April
, 2005. Comments were filed by Commission Staff and a number of interested parties and
project area residents.
In its comments, Commission Staff notes that Thousand Springs is one of four wind
projects proposed in the Bell Rapids area west of the City of Hagerman. Reference Pilgrim Stage
(Case No. IPC-05- 7), Oregon Trail (Case No. IPC-05-8) and Tuana Gulch (Case No. IPC-
05-9). In addition to these four projects, Staff notes that the Fossil Gulch project previously
approved by the Commission is also located in the same vicinity. Construction of the Fossil Gulch
project is nearly complete. These four projects, in addition to the Fossil Gulch project, bring the
total installed capacity in the vicinity to 50 MW. Staff recommends approval of the Agreement
with the Company recommended effective date of February 18 2005.
The comments filed by interested parties and area residents generally support
renewable energy and wind power. Concern was expressed regarding the siting of the towers
however. Many commenters had not expected to see the seven Fossil Gulch wind towers on the
rim, and believe that the placement of additional towers on or close to the rim will ruin the scenic
beauty in the valley and is unconscionable. It is recommended that the towers be sited west of the
rim, out of sight. The flashing aircraft warning lights on the existing Fossil Gulch windmills were
cited as an extremely annoying feature for the residents of the Hagerman Valley. Considering that
the valley floor is nearly 1 000 vertical feet below the tops of these towers, commenters suggest
that the lights need to be shielded so that the lights are only visible 200 feet above the ground level
at the towers. Lights should be shielded, they contend, to avoid light pollution on the grQund.
One commenter suggests that it is important that the siting decisions be done in conformance with
environmental studies that minimize the impacts upon night-flying birds, bats, and raptor flyways.
It is also important, the commenter states, that habitat for prairie grouse (sage grouse, sharp-tailed
grouse, and lesser and greater prairie-chicken) be kept intact and not fragmented by wind turbine
development. Leks and traditional mating grounds, the commenter cautions, should be avoided.
The commenter assumes that environmental studies have been completed by competent scientists
and that the Applicants have configured their development proposals to conform with them.
One commenter notes that in the case of the proposed windmills, Exergy, the project
developer, is changing the viewshed along the Thousand Springs Scenic Byway. This, the
ORDER NO. 29770
commenter states, is a negative impact, but Exergy has an opportunity to offset that impact and
turn their presence into a plus for the local area. Instead of operating merely for their own profit
and to supply electricity to other regions, as a good neighbor, the commenter suggests that Exergy
could assist in local efforts to promote the Thousand Springs Scenic Byway, assist in the cost of
interpreting the wise uses of natural resources, aid in developing recreation attractions and tourism
businesses and support green energy education and resource protection in the Hagerman area.
Commission Findings
The Commission has reviewed the filings of record in Case No. IPC-05-, including
the underlying Agreement and filed comments. Idaho Power has presented a Firm Energy Sales
Agreement with Thousand Springs for Commission consideration and approval. The Agreement
is for a 10.5 MW wind project located in the Hagerman area. As represented and pursuant to
contract under normal and/or average conditions the project will not exceed 10 aMW on a
monthly basis. We thus find that the project is qualified to receive the published avoided costs
rates approved by the Commission.
We find that all commenting parties support the development of wind energy.
Interested parties and local residents, however, have expressed concerns regarding the siting of the
turbines, environmental impact and light pollution. These issues, we note, are matters that fall
outside this Commission s statutory jurisdiction. We are informed by Commission Staff that
James Carkulis of Exergy, the developer of the project, has stated that these concerns are matters
that are the subject of ongoing discussions and matters that can be raised in other forums and
addressed during local conditional use permit hearings.
participate in those discussions and proceedings.
The Commission finds that the Agreement submitted in this case contains acceptable

contract provisions and incl~des the non-Ievelized published rates approved by the Commission in
Order No. 29646. We find it reasonable that the submitted Agreement be approved without
further notice or procedure. IDAP 31.01.01.204. We further find it reasonable to allow
payments made under the Agreement as prudently incurred expenses for ratemaking purposes.
