ORDER NO. 36047

On November 1, 2023, Idaho Power Company (“Company”) made a filing seeking
Commission approval to add the Lamb Weston manufacturing facility in American Falls, Idaho to
the list of customers exempt from Rule C’s aggregated meter reading provisions.
At the Commission’s November 21, 2023, Decision Meeting, Staff recommended the
Commission accept the Company’s request to add lamb Weston to the list of Rule C exemptions
and direct the Company to file a complete list of the customers that have Rule C exemptions.
Having reviewed the record in this case we now issue this Order granting the Company’s
request to add Lamb Weston to the list of companies exempt from Rule C’s aggregated metering
requirements and directing the Company to file a compliance filing with a complete list of Rule C
exempt customers.
BACKGROUND
Idaho Power’s Rule C states that where a customer has more than one delivery point or
separate meters at a single premises, that the meter readings will not be combined or aggregated
for any purpose except for determining if the customer’s total power requirements exceed 20,000
kilowatts.
In Case No. IPC-E-07-02, Order No. 30274, the Commission granted the Company an
exemption from Rule C’s aggregated meter reading provision to allow bills for specific large
accounts to be prepared by combining the readings from multiple meters. Each of the 13 customers
identified in that case involved situations where having multiple meters at the same premises was
the most cost-effective and optimal means of providing service.
Order No. 30274 also authorized a streamlined regulatory procedure for handling future
situations where an exemption to Rule C was merited. Instead of requiring the Company to file a
petition for each additional exemption, the Company was authorized to provide the Commission
with information supporting its decision that an exemption was merited. Unless the Commission
ORDER NO. 36047 2
objected to a proposed exemption, the affected customer would then be added to the list of
customers exempt from Rule C provisions.
STAFF ANALYSIS
Staff reviewed the Company’s request to add Lamb Weston to the Rule C exemption list
and has no objection to adding Lamb Weston to the list. However, to ensure the Commission has
an updated list of all customers under the exemption, Staff recommends the Company provide a
list of Rule C exemption customers to the Commission through a compliance filing.
The Lamb Weston facility is currently a Schedule 19 customer but is expanding the facility
and is expected to soon be above the 20 megawatts (“MW”) load threshold requiring a Special
Contract. A Special Contract for Lamb Weston was approved in Case No. IPC-E-23-18, Order No.
35929. When Lamb Weston exceeds the 20 MW threshold and becomes a Special Contract
Customer, the Rule C exemption will no longer be required because Rule C’s aggregated meter
reading provision will not apply. The configuration that is most economic for Lamb Weston’s
expansion plans is to service the customer using three feeders and three primary metering
packages. This economic justification behind the Company’s request is consistent with the
justification provided in Case No. IPC-E-07-02 where the original 13 customers were approved to
be included on the Rule C exemption list.
The Company in this request stated they will submit an updated list of Rule C exemption
customers to the Commission. Staff agrees and recommends the Company provide the list in a
compliance filing to the Commission within seven days of the Commission’s decision.
O R D E R
IT IS HEREBY ORDERED that the Company’s request to add Lamb Weston to the list of
customers exempt from Rule C’s aggregated metering requirements is granted.
IT IS FURTHER ORDERED that the Company shall file a complete list of customers
granted exemptions from Rule C’s aggregate metering requirements within seven days of the
service date upon this Order and file updated lists when changes occur.
THIS IS A FINAL ORDER. Any person interested in this Order may petition for
reconsideration within twenty-one (21) days of the service date upon this Order regarding any
matter decided in this Order. Within seven (7) days after any person has petitioned for
reconsideration, any other person may cross-petition for reconsideration. Idaho Code § 61-626.
ORDER NO. 36047 3
DONE by Order of the Idaho Public Utilities Commission at Boise, Idaho this 29th day of
December 2023.
