Commission adopts sales agreements
with Grand View Solar, Boise City Solar

BOISE (Nov. 14, 2014) – State regulators today approved sales agreements between
Idaho Power Company and the developers of two solar generation projects totaling 120
megawatts.

Grand View PV Solar Two LLC, 20 miles southwest of Mountain Home, is 80 MW and is
scheduled to be online by Sept. 1, 2016. The project is expected to include about
340,480 polysilicon photovoltaic panels installed on a single-axis tracking system. The
developer is Robert Paul of Boise.

Boise City Solar LLC is a 40-MW project to be built southeast of Kuna on Sand Creek
Road with a proposed online date of Jan. 16, 2016. The project is expected to use
mono-crystalline solar modules and is a dual-axis tracking system, which allows the
tracker to follow the sun both vertically and horizontally. The developer is Mark van
Gulik of Intermountain Energy Partners, headquartered in Ketchum with development
offices in Boise. IEP will lease the land on which the project will be built from the City of
Boise. IEP will be paid by Idaho Power for the project’s output, while the city will receive
lease payments as well as half of the revenue received from the sale of Renewable
Energy Certificates (green tags) associated with the project. Idaho Power will also
receive 50 percent of REC proceeds.

The commission received more than 140 written comments from the public, all
encouraging their approval. “While many of the comments appeared to be based on a
form-letter campaign, many others were original and thoughtful comments from
citizens who appeared to be concerned about the environment and optimistic about the
contribution” the projects would have on the economy. “We appreciate the public’s
participation in our process. “

The projects are the first of their type since the Idaho commission adopted an updated
pricing method for intermittent projects (like solar and wind) that fall under the
provisions of PURPA, or the federal Public Utility Regulatory Policies Act (PURPA). The
commission also has applications for another 11 solar projects totaling 281 MW. (See
related press release also issued today.)

PURPA requires regulated utilities to buy energy from independent, renewable
generation projects at rates established by state commissions. The rate to be paid small-
power producers is called an “avoided-cost rate,” because it is based on the incremental
cost the utility avoids by not having to generate the energy itself or buy it from another
source. The commission must ensure the avoided-cost rate is reasonable for customers
because all amount utilities pay to qualifying small-power producers is included in
customer rates.

The updated pricing method requires the developer and utility to negotiate a rate based
on a methodology that uses the utility’s long-range plan, called an Integrated Resource
Plan (IRP), which considers, among other factors, the utility’s need for the resource and
the times when the energy is generated. “We intend that the IRP methodology be a
flexible tool, taking into account many different variables, and producing a result that
accurately values a project’s capability to deliver resources in relation to the timing and
magnitude of the utility’s need for such resources,” the commission said.

Under the agreements, Idaho Power pays the developers a non-levelized rate over the
20-year term, which means payments increase over the course of the agreement and
vary according to light-load and heavy-load hours of the day and seasons of the year.

For Grand View, payments would vary from as low as $31 per megawatt-hour for light-
load hours during the early months of the agreement to as high as $159 per MWh for
heavy-load hours during the latter years of the agreement. If the payments were
levelized over the 20-year term of the agreement, payments would be about $71.48 per
MWh, after adjustments made by commission staff and Idaho Power. The estimated
20-year contractual obligation based on anticipated generation levels is about $300
million.

The agreement allows for a 5% deviation in monthly energy deliveries. If generation
deviates by more than that, a price adjustment can be imposed against the developer,
but the reduced payment to the developer can be no more than 10%. If there is a
consistent and material deviation from the hourly energy estimates, the project will be
considered to be in breach of the sales agreement.

The Grand View agreement also contains a solar integration charge which the developer
pays Idaho Power to cover the cost of integrating the solar energy into Idaho Power’s
transmission and distribution system. The negotiated charge starts at 99 cents per MWh
in the first year of the agreement and escalates to $1.84 per MWh in 2036.

The agreement with Boise City Solar LLC also includes non-levelized payments over 20
years. Payments would vary from as low as $44 per megawatt-hour for light-load hours
during the early months of the agreement to as high as $113 per MWh for heavy-load
hours during the latter years of the agreement. If the payments were levelized over the
20-year term of the agreement, they would be about $71.43 per MWh, after staff and
company adjustments. The 20-year contractual obligation based on estimated
generation levels is about $160 million. The project is allowed a 2% deviation from its
estimated monthly energy output before a price adjustment can be imposed, also
capped at no more than 10%. And, as with Grand View Solar, material deviations from
hourly energy estimates may be considered as a breach of contract.

The negotiated solar integration charge starts at $1.34 per MWh in the first year of the
agreement and escalates to $3.11 per MWh in 2036.
