SUBJECT: IDAHO POWER’S APPLICATION FOR APPROVAL OR REJECTION
OF A REPLACEMENT ENERGY SALES AGREEMENT WITH J.R.
SIMPLOT COMPANY, CASE NO. IPC-E-16-01

On January 6, 2016, Idaho Power Company filed an Application requesting that the
Commission accept or reject a replacement Energy Sales Agreement between Idaho Power and
J.R. Simplot Company. The Agreement falls under the Public Utility Regulatory Policies Act of
1978 (PURPA), and is a contract for the sale and purchase of electric energy generated by the
Simplot-Pocatello cogeneration project near Pocatello, Idaho. Idaho Power asks that its
Application be processed by Modified Procedure.
BACKGROUND
Under PURPA, electric utilities must purchase electric energy from “qualifying
facilities” (QFs) at rates approved by this Commission. 16 U.S.C. § 824a-3; Idaho Power Co. v.
Idaho PUC, 155 Idaho 780, 789, 316 P.3d 1278, 1287 (2013). The purchase or “avoided cost”
rate shall not exceed the “‘incremental cost’ to the purchasing utility of power which, but for the
purchase of power from the QF, such utility would either generate itself or purchase from
another source.” Order No. 32697 at 7, citing Rosebud Enterprises v. Idaho PUC, 128 Idaho 624,
917 P.2d 781 (1996); 18 C.F.R. § 292.101(b)(6) (defining “avoided cost”).
The Commission has established two methods of calculating avoided cost, depending
on the size of the QF project: (1) the surrogate avoided resource (SAR) methodology, and (2)
the integrated resource plan (IRP) methodology. See Order No. 32697 at 7-8. The Commission
uses the SAR methodology – which applies to the Simplot-Pocatello cogeneration project – to
establish “published” avoided cost rates. Id. Published rates are available for wind and solar
DECISION MEMORANDUM 2
QFs with a design capacity of up to 100 kilowatts (kW), and for QFs of all other resource types
with a design capacity of up to 10 average megawatts (aMW). Id. The Simplot-Pocatello
Project is a QF under the “all other resource type” category. Application at 2.
In calculating avoided cost, the Commission found it “reasonable, appropriate and in
the public interest to compensate QFs separately based on a calculation of not only the energy
they produce, but the capacity that they can provide to the purchasing utility.” Id. at 16. In
calculating capacity, the Commission considers “each utility’s capacity deficiency based on load
and resource balances found in each utility’s [Integrated Resource Plan] IRP,” as well as “a QF’s
ability to contribute to a utility’s need for capacity.” Id. at 16, 21.
THE AGREEMENT
The Agreement between Idaho Power and Simplot replaces an existing contract that
expires March 1, 2016. Application at 2. Under the terms of the Agreement, Simplot elected to
contract with Idaho Power for a three-year term using the non-levelized “other” published
avoided cost rates, as established by the Commission (Order No. 33305) for energy deliveries of
less than 10 aMW. Id. at 4. Because the Agreement in this case is a replacement contract,1 its
rates include capacity payments throughout the contract’s term. Id. at 3.
Although the nameplate rating of the Simplot-Pocatello Project is 15.9 megawatts
(MW), Simplot agrees not to exceed 10 aMW on a monthly basis. Id. at 4. If the facility does
exceed the monthly 10 aMW limit, Simplot agrees that “Idaho Power will accept the energy
(Inadvertent Energy) that does not exceed the Maximum Capacity Amount, but will not purchase
or pay for this Inadvertent Energy.” Id.
The facility is already interconnected and selling energy to Idaho Power, thus the
Agreement specifies a Scheduled First Energy Date and Scheduled Operation date of March 1,
2016,2 but no later than 120 days after Commission approval in a final, non-appealable Order.
Id. at 5. The terms and provisions of the Agreement include that “applicable interconnection
charges and monthly operation and maintenance charges under Schedule 72 will be assessed to
Simplot.” Id. Also, PURPA QF generation “must be designated as a network resource (DNR) to

1 The Simplot-Pocatello cogeneration project has been in operation since at least 1991, and has thus been
contributing to the utility’s resource stack for many years. See Order Nos. 23552, 25353, 28730, 29577, 30028,
32790, 33240.

Operation Date of March 1, 2015.

serve Idaho Power’s retail load on its system.” Id. at 5-6. To maintain DNR status, “there must
be a power purchase agreement associated with [the project’s] transmission service request that
maintains compliance with Idaho Power’s non-discriminatory administration of its Open Access
Transmission Tariff (OATT) and maintains compliance with [Federal Energy Regulatory
Commission] FERC requirements.” Id. at 6. The Agreement provides that it will not become
effective “until the Commission has approved all of [its] terms and conditions and declared that
all payments Idaho Power makes to Simplot for purchases of energy will be allowed as prudently
incurred expenses for ratemaking purposes.” Id.
STAFF RECOMMENDATION
Staff recommends that the case be processed by Modified Procedure with a 21-day
comment period.
COMMISSION DECISION
Does the Commission wish to process this case under Modified Procedure with a 21-
day comment period?
