extensions made under Regulation No. 12.
(e) Extension Allowance—The Extension Allowance is the portion of the Extension that the
Company may provide,or allow,without cost to the Applicant.The portion will vary with
the class of service that the Applicant requests and the Applicant's total load request,and
is the lesser of.the maximum potential Extension Allowance; or,the Extension Cost. The

1. CONDITIONS AND DEFINITIONS (continued)
(h) Facilities Charges—The Facilities Charges are those costs associated with the ownership,
operation and maintenance of facilities built to provide service and are in addition to rate
schedule billings. Schedule 300 specifies the Facilities Charges.
(i) Mixed Use — Mixed Use refers to an Extension request with both residential and
nonresidential loads. Shared Extension costs are allocated as residential and
nonresidential proportional to their respective loads to the total load on the shared
facilities.The provisions for Residential Extensions will be applied to the residential share
of the costs and the provisions for Nonresidential Extensions will be applied to the
nonresidential share of the costs.
(j) Recreational Residential Service — Geographical areas where, in the Company's
judgment, the majority of the dwellings are or will be recreational dwellings shall be
designated Recreational Residential Service areas. Recreational dwellings are single unit
residential dwellings which are or will be used primarily for recreational or vacation
purposes, are not the primary residence of the occupants, and are not generally occupied
on a continuous basis.
(k) Refunds — An Applicant who paid a refundable advance on an Extension, acquired
right-of-way, and/or provided work and material on an underground Extension, is
eligible for up to four refunds during the first ten years. Within that 10-year period the
Applicant may waive any refund that is less than 20% of the Applicant's total refund
amount in order to accept four refunds offering greater value. An Applicant is not
eligible for refunds from future Extension applications from themselves.
Refundable advances are advances paid on those costs that are eligible to be paid by an
allowance, but where those costs exceed the allowance. The refund amount for
Applicant acquired right-of-way will be determined by the Company using the
Company's standard right-of-way costing. For private property this is a percentage of
the right-of-way land value as determined from the county assessor's property land
value. Where there are multiple right-of-way segments, the refund will be determined
using an average of the costs. The refund amount for applicant provided work and
material on an underground Extension will be determined by the Company using the
Company's average costs for standard trenching, conduits and vaults (equipment
foundations) with footages and sizes as per the Company's design.

(b) Deduct Service
The Company may, in lieu of a Line Extension, provide service to a new Customer
(Deduct Customer) through utilization of the electrical facilities owned, operated and
maintained by an existing Customer (Facilities Owner) provided that the Deduct
Customer,the Facilities Owner and the Company each agree with the service arrangement
and enter into a written agreement, referred to as a deduct agreement, that specifies the
terms of the service delivery and is consistent with the terms of this Subsection b.
Beginning January 16,2019,new Deduct Service installations are only allowed where the
Facilities Owner provides service to the Deduct Customer at or below 34.5 kV, and only:
1. As a temporary expediency to provide service for five years or less; or
2. In Remote Service locations where the length of a Line Extension from the Company
to the Deduct Customer will exceed one mile and the cost will exceed seven times the
Deduct Customer's estimated annual revenue.
The Deduct Customer shall bear the risk that it may be unable to obtain service in the
event the deduct agreement is terminated, service to the Facilities Owner is terminated,or
the Facilities Owner is unable to provide service through use of its electrical facilities for
any reason. In the event the Deduct Customer is no longer able to obtain deduct service,
and/or at the expiration of the five-year temporary period, the Deduct Customer may
reinstate service in accordance with the provisions of a Line Extension as provided in this
Regulation.
The Deduct Customer will be billed by a separate meter on a retail rate schedule applicable
to the service the Deduct Customer is receiving. The Deduct Customer shall construct,
own, operate and maintain: all equipment necessary to receive service from the electrical
facilities owned by the Facilities Owner; a Company approved metering point; and
communication for remote meter reading. The deduct-meter will be Company owned
using an approved revenue metering package.
With the addition of the Deduct Customer, the Facilities Owner's meter measures the
usage of both of them, thus is a master meter. The Facilities Owner's usage shall be
calculated by subtracting the Deduct Customer's usage from the Facilities Owner's usage
as metered by the master meter. Under no circumstances is the Facilities Owner to sub-
meter or otherwise charge the Deduct Customer for the electrical energy delivered through
the Facilities Owners facilities, or for any other charge that is based on the amount of the
Deduct Customer's energy use. However the Facilities Owner may enter into a
maintenance agreement with the Deduct Customer for its reasonable costs incurred to
maintain the electrical facilities used to deliver service to the Deduct Customer.
