This collection is a subgroup
(Division) of the Montana Public Service Commission records, RS 501. The Utility
Division is now, as of 2025, named the Regulatory Division. Please see the primary finding
aid for more Montana
Public Service Commission records. These records consist primarily of annual
reports (1914-1986) made by electric utility companies, gas companies, heating utility
companies, water companies, telegraph companies, telephone companies, and pipeline companies
to the Montana Public Service Commission. There are also accident reports (1957-1966) for
electric and gas utilities.

The Montana Board of Railroad Commissioners was established by the Montana legislature in
1907. In 1913 the Board of Railroad Commissioners was made ex officio the newly created
Montana Public Service Commission. As such, it was given the authority to regulate a variety
of public utilities. In 1971, the Montana Board of Railroad Commissioners was abolished and
its work was taken over directly by the Public Service Commission. As of 2025, the Utility
Division is now the Regulatory Division.
These records consist predominantly of annual reports (1914-1986) made by electric utility
companies, gas companies, heating utility companies, water companies, telegraph companies,
telephone companies, and pipeline companies to the Montana Public Service Commission. The
reports include a vast amount of data on the history, financing, corporate ownership,
physical plants, and production. Many of the reports are accompanied by rate schedules and
regulations. Some of the reports are copies of the reports made to the Federal Power
Commission and do not directly reflect their Montana operations.
In addition there are accident reports (1957-1966) for electric, gas, and telephone
utilities; appraisal reports (1919-1927) for several electric utilities; and other reports
(1922-1953) for several water companies.
The collection is arranged by subgroup and then by series.
Collection is open for research.
The Montana Historical Society is the owner of the materials in the Library & Archives and
makes available reproductions for research, publication, and other uses. Written permission
must be obtained from the Library & Archives before any reproduction use. The Society does not
necessarily hold copyright to all of the materials in the collections. In some cases,
permission for use may require seeking additional authorization from the copyright

In 2024, the various collections of the Montana Public Service Commission were integrated
under one collection identifier, RS 501, in order to help facilitate access, reduce
redundancy in the Montana Historical Society Library & Archives catalog, and to follow
best archival practices.
Collections from Montana Public Service Commission's various Divisions and Predecessor
Agencies that were previously treated as separate entities are now integrated into this collection, RS 501. Rather than reprocessing over 80 linear
feet of PSC materials, MTHS staff decided to keep the past arrangement of those
collections/finding aids and provide access to them via links in the primary finding aid.
This decision has allowed the MTHS archival staff to maintain intellectual control over
the collection, while removing the need to reprocess it. It also keeps State Agency
finding aids at manageable sizes. Please read the scope and content note carefully to
determine if this subgroup pertains to your research needs.
