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 CAMP REED WIND PARK LLC
CASE NO. IPC-09-
ORDER NO. 30924
On July 17, 2009, Idaho Power Company (Idaho Power; Company) filed an
Application with the Idaho Public Utilities Commission (Commission) requesting approval of a
20-year Firm Energy Sales Agreement between Idaho Power and Camp Reed Wind Park LLC
(Camp Reed) dated July 9, 2009 (Agreement).
AGREEMENT
Camp Reed proposes to design, construct, install, own, operate and maintain a 22.
megawatts (MW) wind generating facility. The Camp Reed facility will be located near
Hagerman, Idaho, in an area more particularly described as Section 16, the NW 1/4 of Section 22
and the NE 1/4 and E 1/2 of the NW 1/4 of Section 21 , Township 7 S, Range 12 E, Boise
Meridian, Elmore County, Idaho. Camp Reed has selected September 30, 2010, as both the
scheduled First Energy Date and the Scheduled Operation Date. Appendix B-
Agreement ~ 21 provides that the Agreement will not become effective until the
Commission has approved all of the Agreement's terms and conditions and declares that all
payments Idaho Power makes to Camp Reed for purchases of energy will be allowed as
prudently incurred expenses for ratemaking purposes.
On August 4, 2009, the Commission issued a Notice of Application and Modified
Procedure in Case No. IPC-09-18 and established a September 22 , 2009, comment deadline.
Comments were filed by Commission Staff and a number of wind energy proponents. Staff
recommends that the Firm Energy Sales Agreement between Idaho Power and Camp Reed be
approved.
ORDER NO. 30924
COMMISSION STAFF COMMENTS
Purchase Rates
The Agreement contains levelized published avoided cost rates as currently
established by the Commission for energy deliveries of less than 10 aMW. Agreement Article
VII. Staff confirms that the rates in the Agreement comport with those contained in Order No.
30744. Rates in the Agreement are adjusted seasonally, and a daily load shape adjustment is
made in accordance with Order No. 30415. In addition, a wind integration adjustment has been
applied in accordance with Order No. 30488.
Security for Levelized Rates
The rates contained in the Agreement are levelized rates.Levelized rates have
become rare in recent years due to the requirements for security; consequently, Staff reviewed
the security requirements carefully.
The Commission in its implementation of PURP A and the related rules and
regulations of the Federal Energy Regulatory Commission (FERC) has utilized levelized rates as
an incentive to the development of the cogeneration and small power production industry.
Levelization provides the project developer with a price for supplied power at the front-end of
the contract in excess of the power s actual energy value, thus enabling the project to better
service its debt and meet start-up costs. In later years the cumulative overpayment is recouped
because the payments at levelized rates are projected to be less than the value of the power.
the end of the contract, the cumulative sum of overpayments and underpayments theoretically
will be zero.
In the event of a default, some project owners may be unable to refund this
overpayment unless they maintain some form of liquid security to provide the funds. The
Commission requires that liquid security be made available to the utility (and thus its ratepayers)
in an amount equal to the computed overpayment liability, adjusted for risk reduction. The need
for security for the amount of overpayment attendant to the front-end loading is commensurate
with the perceived risk of economic walk away by the project owner and the consequential or
ensuing loss to the utility's ratepayers. The Commission has determined previously that the
required liquid security for overpayment liability can be reduced by (1) having adequate
Insurance, (2) obtaining engIneerIng certification of the project's design and construction
adequacy, (3) obtaining engIneerIng certification of the project's ongoing operations and
ORDER NO. 30924
maintenance policies, (4) establishing a maintenance and debt service escrow, and (5) granting
the utility second lien rights. Reference Order No. 21690.
This Agreement includes the various security requirements required by Commission
Order No. 21690 for levelized agreements (i., debt service reserve account (~ 19.3.2),
maintenance reserve account (~ 4.19), second lien requirements (~ 4.10), and an expanded list
of required insurances (~13.2). Although all other security requirements contained in the
Agreement are standard and in compliance with prior Commission Orders, the minimum balance
requirement for the maintenance reserve account is specific to this particular project.The
Agreement requires that a minimum of $2 million be retained in a maintenance reserve account.
This amount is estimated to be the approximate cost to completely replace one wind turbine
should failure occur. The amount would be adjusted upward or downward every three years to
reflect current replacement costs. Staff believes this minimum balance amount is reasonable for
wind projects of this size.
New Wind Contract Provisions
Staff notes that the submitted Agreement is one of the first PURP A wind agreements
executed since the issuance of Commission Order No. 30488, which requires the inclusion of the
Mechanical Availability Guarantee (MAG) (~ 6.4), wind integration cost reduction (~ 7.1), and
wind forecasting cost sharing (Appendix E). The Commission approved these provisions for
future wind contracts as an acceptable substitute for the "90/110" requirements in earlier
contracts. The 90/110" provisions required facilities to predict future monthly generation with a
fairly high degree of certainty within a 90/110 band in order to justify payment of "firm" energy
rates. For resource technologies with intermittent generation (like wind), the "90/110"
requirements were difficult to meet.
Under the MAG provisions in this Agreement, the project is required to achieve a
minimum monthly mechanical availability of 85 percent. In other words , the project must be
able to operate at least 85 percent of the hours in the month, not counting hours when wind
speeds are too low or too high, force majeure events, forced outages, and scheduled maintenance
periods. Failure to achieve an 85 percent mechanical availability results in damages being
assessed equal to the difference in the per kWh price between the contract rates and
corresponding market energy prices, subject to a minimum price penalty of 15 mills per kWh.
The 15 mills per kWh minimum price penalty is intended to recognize that Idaho Power will
ORDER NO. 30924
incur transaction and administrative costs to acquire replacement power even if market prices are
less than contract rates. Staff believes that the MAG provisions in the Agreement are reasonable
and recommends that they be approved.
As specified in Order No. 30488 , Idaho Power shall make use of a wind energy
production forecasting model to forecast the energy production from this facility and other QF
wind generation resources. Idaho Power will share the cost of wind energy production
forecasting equally with the project owner. The facility s share of wind energy production
forecasting will be prorated based on its generation in relation to all other QF wind projects
providing energy to Idaho Power. The project's share will not be greater than 0.1 percent of the
total energy payments made to the project by Idaho Power during the previous contract year.
Delay Liquidated Damages and Security Provisions
Staff notes that the Agreement contains provisions for delay liquidated damages (~
3) and associated delay security (~ 5.7) to secure the established scheduled operation date of
September 30, 2010. Delay liquidated damages have been included in contracts since July 2007;
however, this will be one of the first contracts to require delay security.
Under the terms of the Agreement, for online delays of up to 90 days, liquidated
damages are assessed if Idaho Power must pay more to acquire replacement power than it would
have otherwise paid to purchase power under the contract. If a delay in the project's online date
extends beyond 90 days, liquidated damages of $20 per kW will be assessed ($450 000 based on
a capacity of 22.5 MW). In addition, Idaho Power can choose to terminate the Agreement if the
delay in meeting the scheduled operation date extends beyond 90 days. In order to ensure that
the project will be able to pay delay liquidated damages should they be incurred, the project is
required to post liquid security in an amount equal to $20 per kW of project capacity. Staff
believes that these provisions are necessary and reasonable. When projects are delayed, Staff
notes that the Company must sometimes incur higher costs to acquire replacement power.
Generator Interconnection and Transmission
The Camp Reed, Yahoo Creek and Payne s Ferry projects are proposed to be located
in an area west of Hagerman, in close proximity to each other and to several other proposed and
existing projects. Projects in this vicinity were studied as a cluster in connection with Case No.
IPC-06-21 ("Cassia Case ). One outcome of that case was a Settlement Stipulation that
determined the transmission system improvements necessary in order to accommodate all of the
ORDER NO. 30924
proposed projects in the cluster, and devised a method for allocating costs amongst Idaho Power
and each of the projects. The Camp Reed, Yahoo Creek and Payne s Ferry projects were
included in the Settlement Stipulation.
In addition to the Power Sales Agreement, Staff states it will be necessary for a
Generator Interconnection Agreement to be signed before the project can proceed. The terms
and costs to be included in the Generator Interconnection Agreement will be in accordance with
the "Cassia Formula" as included in the Stipulation in Case No. IPC-06-21. Moreover, the
transmission interconnection costs to be assigned to the three projects will be based on
redispatch" as described in the Stipulation in the Cassia Case.
Although a Generation Interconnection Agreement has yet to be negotiated
, "
Facility
Studies the last in the series of three transmission studies are complete for the three
projects. Exergy, the developer ofthe Camp Reed, Yahoo Creek and Payne s Ferry projects, had
until September 23 , 2009, to respond with comments on the Facility Study Report. The
Generation Interconnection Agreement will be drafted from the Facility Study Report and be
sent to Exergy within 30 calendar days of Exergy s comments on the Facility Study Report.
Based on the interconnection studies to date and the discussions with Exergy, Idaho Power has
concluded that, assuming Exergy continues to provide necessary technical information and pay
for long lead time materials in a timely manner, the Company will have sufficient time and
available resources to construct the interconnection facilities in time to allow the expansion
facilities to meet the Scheduled Operation Date.
COMMISSION FINDINGS
The Commission has reviewed the filings of record in Case No. IPC-09-
including the proposed Agreement and filed comments. We note that Idaho Power appears
satisfied in this case that transmission and generator interconnection issues are unlikely to cause
a delay in the project's Scheduled Operation Date.
Idaho Power has presented a Firm Energy Sales Agreement with Camp Reed Wind
Park LLC. As represented and pursuant to contract, under normal andlor 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 cost rates approved by the Commission. We note that Idaho
Power appears satisfied in this case that transmission and generator interconnection issues are
unlikely to cause a delay in the project's Scheduled Operation Date.
ORDER NO. 30924
The Commission finds that the proposed Agreement submitted in this case contains
acceptable contract provisions and includes levelized published avoided cost rates approved by
the Commission in Order No. 30477. We find it reasonable that the submitted Agreement be
approved without further notice or procedure. IDAP A 31.01.01.204. We further find it
reasonable to allow payments made under the Agreement as prudently incurred expenses for
ratemaking purposes.
