SUBJECT: IDAHO POWER’S REQUEST FOR A DETERMINATION REGARDING
AN ENERGY SALES AGREEMENT WITH GRAND VIEW PV SOLAR
TWO, CASE NO. IPC-E-14-19

On July 25, 2014, Idaho Power filed an Application with the Commission for
approval or rejection of an Energy Sales Agreement with Grand View PV Solar Two, LLC, for
the sale and purchase of electric energy. Idaho Power requests that its Application be processed
by Modified Procedure.
THE APPLICATION
Idaho Power requests that the Commission accept or reject the Energy Sales
Agreement between Idaho Power and Grand View PV Solar Two, LLC (Grand View) under
which Grand View would sell and Idaho Power would purchase electric energy generated by
Grand View’s 80 megawatt (MW) solar photovoltaic project located approximately 20 miles
southwest of Mountain Home, Idaho. The Agreement between the parties was executed on July
17, 2014.
The Agreement is for a term of 20 years. Idaho Power states that the Agreement was
executed in compliance with the Commission’s Orders directing the implementation of PURPA
for the State of Idaho and contains negotiated avoided cost rates based upon the incremental cost,
integrated resource plan pricing methodology available to solar projects whose generation will
exceed 100 kilowatts (kW). Idaho Power explains that the Agreement also contains negotiated
solar integration charges as directed by the Commission in Order No. 33043, as well as several
other negotiated provisions requiring specific Commission approval.
The proposed project is expected to consist of approximately 340,480 polysilicon
photovoltaic panels installed on a single axis tracking system, supported by a fixed post and
beam structure. Grand View selected July 1, 2016, as its Scheduled Operation Date. Various
DECISION MEMORANDUM 2
requirements have been placed upon Grand View in order for Idaho Power to accept energy
deliveries from the project. Idaho Power states that it will continue to monitor compliance with
these requirements throughout the term of the Agreement.
Idaho Power explains that this Agreement is the first of its type submitted for
approval that contains negotiated avoided cost rates based upon the incremental cost, integrated
resource plan pricing methodology. Prices were determined on an incremental basis with the
inclusion of this project in its queued position of proposed projects on Idaho Power’s system.
Over the 20-year term of the Agreement, monthly rates vary from approximately $31/megawatt-
hour (MWh) for light load hours in early months of the Agreement to as high as $159/MWh for
heavy load hours in the later years of the Agreement. The equivalent 20-year levelized avoided
cost rate would amount to approximately $73.41/MWh.
The Agreement also contains a solar integration charge that was negotiated and
agreed to by the parties. Although the integration charge is based on Idaho Power’s solar
integration study, the study was not yet complete during contract negotiations. However, the
most currently available data and analysis from the study was used by the parties in the course of
negotiations. The negotiated solar integration charge starts at $0.99/MWh for the first year of
the Agreement (2015) and escalates to $1.84/MWh in 2036. The equivalent 20-year levelized
solar integration charge would amount to approximately $1.28/MWh. Idaho Power states that
the 20-year estimated contractual obligation based upon estimated generation levels, including
avoided cost rates and solar integration charges, is approximately $310,237,634.
The Agreement does not contain a 90/110 firmness requirement; instead it contains
provisions for a Mechanical Availability Guaranty (MAG), solar forecasting fees, solar
integration charge, and a pricing adjustment. Idaho Power states that it prefers that 90/110
firmness be included in all PURPA QF agreements. The project preferred a MAG and
forecasting costs. Idaho Power maintains that the use of a MAG is not a replacement for the
firmness determinations of the 90/110 provisions; however, based on negotiations and an agreed
to price adjustment, the Company states that it is comfortable and confident that the Agreement
contains provisions to reasonably assure that the project performs in conformance with its
generation estimates and, if not, the project receives a reduced price for the non-conforming
month’s generation. The Agreement allows for a five (5) percent deviation in the monthly net
energy deliveries from the generation profile estimates without assessing a price adjustment. If
the project’s actual generation deviates downward by more than 5% of its generation estimates,
then a corresponding percentage adjustment to the monthly price is imposed. However, the
DECISION MEMORANDUM 3
adjustment is limited to a maximum price reduction of 10 percent. Idaho Power states that
consistent and material deviations from the hourly energy estimates in the generation profile will
be considered by Idaho Power to be a material breach of the Agreement.
New provisions providing for actual delay damages as opposed to liquidated damages
are included in the Agreement, consistent with Order No. 32697. The parties negotiated a 50/50
split of environment attributes (aka renewable energy credits). As with all PURPA QF
generation, the project must be designated as a network resource (DNR) to serve Idaho Power’s
retail load on its system. Consequently, the Agreement contains provisions requiring completion
of a Generator Interconnection Agreement (GIA), compliance with GIA requirements, and
designation as an Idaho Power network resource as conditions of Idaho Power accepting delivery
of energy and paying for the same under the Agreement. In order for the project to maintain its
DNR status, there must be a power purchase agreement associated with its transmission service
request that maintains compliance with Idaho Power’s non-discriminatory administration of its
Open Access Transmission Tariff (OATT) and maintains compliance with FERC requirements.
Article 21 of the Agreement provides that the Agreement will not become effective
until the Commission has approved all of the Agreement’s terms and conditions and declared
that all payments Idaho Power makes to Grand View for purchases of energy will be allowed as
prudently incurred expenses for ratemaking purposes.
STAFF RECOMMENDATION
Staff has preliminarily reviewed the Application and recommends that the case be
processed by Modified Procedure.
COMMISSION DECISION
Does the Commission wish to process this case under Modified Procedure?
