WESTERN COLORADO POWER COMPANY RECORDS

Years: 1885-1982
approximately 100 linear shelf feet (roughly 100,000 items in about 220 boxes and 3 file drawers)

Records and correspondence from the establishment and daily operation of the Western Colorado Power Company and predecessor electrical power generation companies on the Western Slope of Colorado between Cedaredge and Durango.

This is a remarkably comprehensive collection which documents Colorado's San Juan Basin power company operations in meticulous detail for the period from 1885 to 1982, especially from 1888 through the 1960s.  The bulk of these materials are early business correspondence (Record Group 2) and monthly, weekly and daily reports of electricity production, transmission and distribution (RG 4).  Several thousand photographs (RG 8), well identified for the most part, document the Western Colorado Power Company's electricity installations in the region, and include photos of important mining towns, 1890-1970.

In the arrangement and description of this collection, the Center of Southwest Studies archival staff retained nearly all of the Western Colorado Power Company records acquired, with the exception of 5 cubic feet of oversize rolled daily log sheets (Form 175B) from the Ilium power plant for the years 1939-1950.  Detailed records that might have been deaccessioned in normal circumstances were retained when this collection was processed, due to the worldwide historical significance of the Western Colorado Power Company and the power plants and power companies it inherited.  The engineering records (record group 3, including many rolled blueprints and many other types of records which require labor-intensive archival work) have not yet been completed processed.

This collection is important for anyone studying rural electrification and the early years of hydroelectric power generation and transmission.  As the Center's founding Director Robert Delaney noted, this collection is especially valuable for understanding the history of Colorado's western slope because it documents the electrification of several municipalities and practically all of the mines in the San Juan Triangle, including the change from steam power to electricity.  The Ames Power Plant, located near Ophir, was the first commercial high-voltage alternating-current generation and transmission system in the world, antedating by several months another successful experiment in Germany in 1891.

The business correspondence of L. L. Nunn and his colleagues (in Series 2.1) is a particularly rich source of documentation regarding the early use and development of alternating current and for its documentation of life in Western Slope towns from 1888 to 1911.  In the 1980s a work-study student, Ruth Boyd, created a calendar of the contents of these 28 boxes, housed in two loose-leaf notebooks.  This item-level descriptive guide was produced before the collection was arranged, so the box numbers referred to in the calendar are now incorrect.  In time the Center of Southwest Studies may scan the calendar pages optically so that the text can be reformatted (attempts to do so thus far have proved futile, due to the difficulty of the optical character recognition of the existing photocopies of columns of text on typewritten pages).  Instead, we have provided folder-level descriptions of all of that business correspondence.

Historical note

Owners of gold and silver mines in the vicinity of Telluride, Colorado, faced a critical problem in the late 1880s.  To quote a booklet published by the Western Colorado Power Company on its fiftieth anniversary of electrical service, "Operating costs soared as the rich ores petered out.  When digging became poorer, concentration became necessary and mills were erected near the mines." (The First 50 Years: A Romance of Electricity on the Western Slope, [1963], p. 3)   The mills were powered mostly by steam engines fueled with wood; later, as the adjacent timber supply was depleted, the engines used coal.  Fuel and transportation costs were forcing mine owners into bankruptcy.  Use of electricity on the Western Slope had begun a few years earlier, but "service was limited to direct current used mostly to light a street arc lamp or a business or two in only a few communities." (p. 3)

At Ames, Colorado, high in the Colorado Rockies in the region where such pioneers as Otto Mears had carved narrow gauge railroad tracks, an important historical development solved this problem and inaugurated the widespread use of electricity.  L. L. Nunn, the man primarily responsible for the solution, was a lawyer who had come to Colorado in 1880. "He became manager for the eastern interest of the Gold King mine, and with Judge William Story, of Ouray, began to take up water rights in the area and operated a ten-stamp mill at Ophir, 15 miles from Telluride, which was run by water power from a water wheel." (p. 4)

Two thousand feet below the Gold King mine, but only three miles from it, the Howards Fork and the Lake Fork of the San Miguel River met and rushed down through the mountains with ample potential horsepower to run all the mills in the area.  During his association with Judge Story, Nunn considered various possibilities, such as cable drive, compressed air and direct current, for harnessing this potential power source.  He learned about George Westinghouse's experiments with `Westinghouse current' (alternating current), and called for technical help from his brother P. N. Nunn, who later became chief engineer for the Ontario Power Company plant at Niagara Falls.  L. L. Nunn, never married, possibly had a romantic homosexual relationship with A. M. Wrench, another member of this team.  The 28 boxes of business correspondence of L. L. Nunn and his associates contain letters and telegrams transmitted by these and other individuals.

The problem with direct current was that electricity generated at low voltages could not be raised in voltage to give it more pressure for transmission.  Although all existing motors and other electrical equipment were designed for direct current operations, alternating current was the only practical current for transmission in the rugged Colorado mountains. Easterners--including Thomas Edison--and outside engineers predicted that Nunn's scheme would fail, but they soon were proved wrong.  During the winter of 1890, Nunn's team built a crude wooden shack in which they installed the necessary machinery at the junction of the two streams deep in a valley gorge at Ames.  A Westinghouse generator was belted to a six-foot Pelton waterwheel, and a Westinghouse motor was installed at the mill 2.6 miles away, which in those days was an unheard of distance to transmit electricity.  The generator and the motor were identical alternators of 100 horsepower, capable of producing 3,000 volts, 133 cycle, single-phase power.

"The [Ames] plant started up in 1891 and power surged over the mountain ridge to the Gold King mine.  Despite its simplicity, it ran smoothly and steadily for 30 days without a stop after its initial start. ... The plan succeeded and preceded the similar Laufen-Frankfort experiment in Germany by two months. ... Electrical World Magazine described the Ames plant just before it went into operation `one of the most interesting plants in the world.'" (p. 6)  During its initial months of operation, a large crowd was apt to gather on a Sunday evening to watch the "oft' times spectacular start-up of the machinery, shutdown the night before for the Sabbath Day." (p. 7)   It seemed incredible to them that electrical current--or anything--could travel 186,000 miles a second.  Many people were skeptical as to the safety and benefits of electricity.

Originally, small power companies formed as plants were built to serve a mine or a mill.  The plants were not interconnected, so if a mill or mine ceased operations the plant was useless.  Other electrical pioneers were operating plants (using direct current) in the towns of Durango and Ouray, just five years after Thomas Edison's Pearl Street Station had started operating in New York City in 1882.  On November 11, 1885, a group of Durango citizens organized the Durango Light and Power Company which delivered the first electric service to that town early in 1887.  Home and business owners in Durango had the option of electricity from dusk to 10 p.m., to midnight, or all night.  Durango's first power station was a small steam plant east of the railroad tracks on 7th Street.  Ironically, Silverton, one of the first mining camps on the Western Slope to have a power plant, used coal rather than its abundant streams to produce steam. (p. 11)

In the 1900s the Animas River was tapped as a source for hydroelectric power to serve the rich mining district of the Silverton area.  The Animas Power and Water Company generated this power at its Tacoma Plant.

The Western Colorado Power Company (WCPC) was organized on March 12, 1913.  By the next year it had consolidated the operations of eight major companies: the Durango Gas and Electric Company, San Juan Water and Power Company, Nunn's Telluride Power Company, the Telluride Electric Light Company, and (in 1914) the Ouray Power and Light Company, Montrose Electric Light and Power Company, Delta Electric Light Company, and Ridgway Electric Company.  The new Western Colorado Power Company encompassed thirty predecessor companies, which had an average corporate life of only six years.  Networking of the formerly isolated power plants was a daring concept, never before attempted on this scale.  It involved construction of transmission lines through the steep mountains and construction of additional power generation sources.  One result was a sharp decrease in the costs of electrical service.  Before the turn of the century, users paid up to $4 a month to light up four dim bulbs; fifty years the average homeowner could light the entire house for considerably less than that. (p. 12-13)

The Western Colorado Power Company was regulated by various government agencies including the State Utility Commission (which approved the rates), the Federal Power Commission (authorized to regulate rates and conditions of service on utilities licensed by the federal government), the Securities and Exchange Commission (regulating the issuance of company securities), and the communities which granted local franchises to the company.

Western Colorado Power Company was a wholly owned subsidiary of the Utah Power and Light Company (organized in 1912 with a purchase of the properties of the Telluride Power Company) from the beginning.  Due to a divestiture order from the Federal Securities and Exchange Commission, Western Colorado Power Company was sold in May of 1975 to a group of rural electric cooperatives serving in the same general areas as the Western Colorado Power Company.  Former employees of Western Colorado Power Company formed the Old Timers Association in 1948, which remained active through the 1970s.

Administrative information

About the organization of this collection:  This is a complex large collection, because it comprises the work of a number of formerly separate companies.  The records are grouped by record group or sub-group (i.e., power company), and within that they are organized by series of similar records.  Most record groups are organized from highest hierarchical level to lowest, or from most general to most specific; two exceptions are power development records (SG 3.4) and station production records (Sub-groups 4.3 through 4.21), which are arranged alphabetically.  Items within each series (e.g., data sheets, payrolls, memoranda and correspondence, and reports) and within each box and folder are arranged chronologically, unless noted otherwise.   The series groups are numbered consecutively, starting at 1 in each series.  Box numbers start with 1; folder numbers start with 1 in each box.

Acquisition information:   In the late 1970s/ early 1980s, Carly McKnight, supervisor of the Western Colorado Power Company in Montrose where the company was headquartered, was ordered to get rid of these records.  He contacted Fort Lewis College and they were transferred to the Center of Southwest Studies through the efforts of Fort Lewis College Professor Duane Smith.  Dr. Smith brought the records to the Center from Montrose and from the Durango Steam Electric Generating Station on Camino del Rio over a period of several years in the late 1970s/early 1980s.

It is possible that some of the records that were still needed by the various power company successors (due to the records' administrative, legal or fiscal primary values) were retained for transfer to those power companies.  Such records may include many of the deeds and easements for the power development projects.

Eric R. Jacobson, current owner of the Ouray and Telluride power plants, provided much of the above information about how the collection came to Fort Lewis College.  He has informed the Center of Southwest Studies that he has in his own possession about the same volume of records as is at the Center.  Many of his records focus on the Ouray plant.  Jacobson notes that Deep Springs College in Bishop, California has records of L. L. Nunn; Paul Swatek of Chicago is on that College's board of directors and is perhaps the best contact regarding those records.  Other records are available at the Olin Library of Cornell University in Ithaca, New York.

Processing information:  This collection was arranged and described by J. Todd Ellison, Archivist, ending in September, 1992.  The inventory was prepared by Todd Ellison, September 4, 1992, and was edited in September of 1998 and December of  2001.  Initial html conversion was done by Jesse Davila in September of 1998.  Subsequent html editing work was done by Debra Lehl in March of 1999.

Four CDs donated to the Center by Denis Clark (accession 2001:08001): (1) "DS Archive Scan," consisting of images scanned this past Spring by members of the Deep Springs student body from their archives, concentrating on pre-Deep Springs College (Calif.) (i.e., pre-1917) images; (2) "CU Archive Scan," consisting of images scanned this past Spring [2001] by Cornell University Library employees, mostly to supply some images on subjects that Clark had none for in his "Telluride Power" book; (3) "DEC Nunn Archive v1," images Clark  scanned or photographed himself (DEC is Denis E. Clark) over the past several years, in some cases overlapping the other two CDs;" and (4) a CD Vol. 2. of the remainder of the digital images of records documenting the early days of the Telluride Power Company, pertaining to the plant at Grace, Idaho, along with some modern-day images of Grace and some other recent publications in electronic form as Denis Clark mentioned them on the cover letter and the j-card of the CD.  The most helpful item on that last CD, for many researchers, is the electronic version of an earlier unabridged version (ca. 1,800 pages) of the History of the Telluride Power Company, an unpublished manuscript history of L. L. Nunn and the Telluride Power Company and related hydroelectric companies, et al., by Orville J. Sweeting, 1970, and also the memoir by Stephen Bailey, 1933 with updated version dated 1993.

See also the Center's microform collection I 063, which is one roll of microfilm (from Cornell University, where much additional material pertaining to L. L. Nunn is housed) of History of the Telluride Power Company, an abridged version of the unpublished manuscript history of L. L. Nunn and the Telluride Power Company and related hydroelectric companies, et al., by Orville J. Sweeting, 1975.
