Rule No. 18
LEVEL 1 SMALL GENERATOR FACILITY INTERCONNECTION AGREEMENT
(continued)
Applicability:
For Small Generator Facilities with an Aggregate Nameplate Capacity of up to 50 kilowatts
(kW) alternating current (AC), approved for Interconnection under Level 1 Expedited .
Level 1 Interconnection Agreement
This Small Generator Interconnection Agreement (“Agreement”) is made and entered into
this 12th day of May 2026 (the “Effective Date”), by NorthWestern Corporation, a Delaware corporation
d/b/a NorthWestern Energy (“NorthWestern”) with offices at 11 E. Park, Butte, Montana, 59701-9394,
and City of Bozeman - Bozeman Public Library, a City organized under the laws of the State of Montana (“Customer-Generator”) with an address of 626 East Main Street in Bozeman, Montana.
Customer-Generator and NorthWestern each may be referred to as a “Party” or collectively as the
“Parties” herein.
Premise Number: 335943
When used in this Agreement, with capitalization, the terms specified shall have the meanings
indicated or specified in the Agreement.
1.Request for Interconnection. Customer-Generator’s request for Interconnection as approved by
NorthWestern, is made part of this Agreement and incorporated herein as Attachment 1. The Small
Generator Facility shall be constructed in the configuration and with the equipment specified in the
approved request. To the extent there is any deviation that is not agreed to in writing by
NorthWestern, the submission of a new request for Interconnection by the Customer-Generator is
required.
2.No Future Modifications to the Small Generator Facility. Customer-Generator agrees that,
without prior written permission from NorthWestern, no modifications shall be made to the Small
Generator Facility as initially approved by NorthWestern. NorthWestern’s review shall be
completed within 10 business days of receipt of any request for modification. Any increase to the
Small Generator Facility Nameplate Capacity requires a new request for Interconnection. Repair
and replacement of existing Small Generator Facility components with like components that meet
the current versions of Underwriters Laboratories (UL) 1741 certification and Institute of Electrical
and Electronics Engineers (IEEE) 1547 requirements for Level 1 facilities and not resulting in
increases in Small Generator Facility Nameplate Capacity do not require approval. If the Small
Generator Facility includes storage components, Customer-Generator shall maintain the settings
originally approved by NorthWestern as detailed in Attachment 1.

(continued)
3.Installing, Operating, and Maintaining the Generation Facility. Customer-Generator shall
construct, operate, and maintain the Small Generator Facility, at Customer-Generator’s sole cost
and expense, in accordance with Customer-Generator’s request and the current version of IEEE
1547, the current version of UL 1741, the regulations of the Montana Public Service Commission
(MPSC), NorthWestern’s approved tariffs, all other applicable local, state, and federal codes and
laws. Customer-Generator shall remain responsible for the Small Generator Facility through the
point of Interconnection – the point where Small Generator Facility connects with the Electric
Distribution System.
4.Permits and Approvals. Customer-Generator is responsible for obtaining all required permits and
approvals for its Small Generator Facility and is responsible for the actions of contractors or other
agents hired by Customer-Generator for design and installation of the Small Generator Facility.
5.Protection of the Small Generator Facility. Customer-Generator is responsible for protecting, at
Customer-Generator’s sole expense, its Small Generator Facility from any condition or disturbance
on the Electric Distribution System, including, but not limited to, voltage sags or swells, system
faults, outages, loss of a single phase of supply, equipment failures, and lightning or switching
surges, except that NorthWestern shall be responsible for repair of damage to the Small Generator
Facility resulting solely from negligence or willful misconduct on the part of NorthWestern.
6.Electrical Isolation of the Small Generator Facility. The Small Generator Facility shall be
capable of being manually isolated from the Electric Distribution System by means of an external,
lockable, visible load break disconnect switch accessible by NorthWestern. The disconnect switch
shall be installed, owned, and maintained by the Customer-Generator and located within 10 feet of
Customer-Generator’s electric meter and shall be clearly marked “Generator Disconnect Switch”
on a weather resistant placard. This switch shall be readily accessible to NorthWestern personnel
at all times, and NorthWestern may lock this switch open whenever necessary to maintain safe
electrical operating conditions. If the disconnect switch will be located farther than 10 feet away
from the NorthWestern meter, written permission must be granted by NorthWestern and a weather
resistant placard shall be mounted next to the meter indicating clearly where the disconnect switch
is located.
7.Metering. Any metering necessitated by the Small Generator Facility Interconnection shall be
installed, operated, and maintained by NorthWestern. NorthWestern will provide a net metering

Customer-Generator a standard meter capable of registering the flow of electricity in two directions
at no additional charge. A non-net metering Customer-Generator shall be responsible for
NorthWestern’s reasonable and necessary metering costs related to the Small Generator Facility
Interconnection as specified in Attachment 2 to this Agreement.
8.Witness Test.
_____ If there is an “X” on this line, NorthWestern intends to perform a witness test after the
Small Generator Facility is completed. Customer-Generator shall provide NorthWestern
at least 20 business days’ notice of its planned commissioning test. Upon receipt of such
notice, NorthWestern shall contact Customer-Generator to schedule the witness test at a
mutually agreeable time within 10 business days of the scheduled commissioning test. If
NorthWestern does not perform the witness test within 10 business days of the
commissioning test, the witness test is deemed waived. If the witness test is not acceptable
to NorthWestern, NorthWestern must document all deficiencies and provide a written
report identifying the deficiencies to Customer-Generator within 5 business days of the
witness test. Customer-Generator shall be granted a period of 30 business days to address
and resolve any deficiencies.
__X__ If there is an “X” on this line, NorthWestern waives its right to perform a witness test.
Once parallel operation of the Small Generator Facility has been authorized by
NorthWestern pursuant to Section 10 of this Agreement, NorthWestern may not require
Customer-Generator to further test its facility.
If a witness test is not performed by NorthWestern or an entity approved by NorthWestern,
Customer-Generator must still satisfy the Interconnection test specifications and requirements set
forth in the current version of IEEE 1547. Customer-Generator shall, if requested by
NorthWestern, provide a copy of all documentation in its possession regarding testing conducted
pursuant to the current version of IEEE 1547.
9.Inspection. NorthWestern reserves the right to inspect the Small Generator Facility before and
after Interconnection approval is granted by NorthWestern, at reasonable hours and with reasonable
prior notice provided to the Customer-Generator.
10.Authorization to Interconnect and Operate. Except as necessary for operational testing, the
extent of which is not to exceed 2 hours, Customer-Generator shall not operate the Small Generator
