Although history is not completely clear, it seems in 1909, the Colorado Electric Light, Power and Railway Association changed its name to the Colorado Electric Club. One of its first activities was an electric show, held in the fall of 1910. It was the first show of its kind west of the Mississippi.

The biggest attraction was a radio set, or “wireless” receiver. Hundreds of visitors trekked from the first floor, where the transmitter was placed, to the basement where a receiver blaring forth raspy music had been hidden in a wicker basket. It was the first time for many Denverites to witness the wireless transmission of sound.

Other exhibits included Westinghouse motors and heavy equipment; the Nernst and Tantalum lamps, neither of which survived commercially; an arc lamp moved from its location in front of the Oxford Hotel; appliances featured in the sales rooms of the Denver Gas & Electric Company; floor and table lamps furnished by the Sechrist Electric Company; and heavy-duty scales from the Mine & Smelter Supply Company. Practically all of the Denver Area electrical industry participated.

In 1916, the Colorado Electric Club membership had soared to 1,026 individuals, due to interesting weekly luncheons that featured prominent speakers from all fields, and the popularity of the social and business functions.  

The annual Christmas Lighting Contest began during this time. Christmas lighting originated in Denver in 1914 when David Sturgeon, son of David D. Sturgeon, then head of Sturgeon Electric Company, lay ill in his home. While his father was putting lights on a Christmas tree in his room, young David, who from his bed could see an evergreen tree in the front yard, said, “Daddy, if you could put some lights on that tree outside, it would look wonderful!” The father granted his son’s request, thus creating the first electrically decorated live evergreen tree anywhere in the world. Neighbors followed suit and the tradition was established. In 1918 the annual Christmas Lighting Contest was established; co-sponsored by The Denver Post and the Denver Junior Chamber of Commerce.

The make-up of the Colorado Electric Club had grown and now only one-third of the membership was connected with the electrical industry. In 1921, the Colorado Electric Club was transformed into the Electrical Cooperative League of Colorado to become a pure electrical association with membership from only the electrical industry. In 1925 the name was shortened to the Electrical League of Colorado. It was first headed by T.O. Kennedy of the Denver Gas and Electric Company. Sidney Bishop was appointed Executive Manager. The Electrical League of Colorado had four divisions of membership: Contractors, Manufacturers, Distributors, and Utilities.

The big task of educating the electrical industry and the public about proper and sufficient wiring was undertaken in 1925 through the Red Seal Plan. To get all homes wired properly was the program’s aim and increased installation of outlets was stressed. Many model electric homes were sponsored by the Electrical League of Colorado. The first home to be shown to the public in Denver was visited by 5,317 adults. Many features of the Red Seal Plan were embodied in the National Adequate Wiring Program and pioneered in the Rocky Mountain region.  

In 1930, the Rocky Mountain Electrical Association began as part of the National Electric Light Association. G. E. Lewis was the managing director.

The Larry Cargo Annual Golf Tournament was started in 1931 at which time Mr. Cargo donated the original cup. Succeeding this was the annual Ross Adams Golf Tournament held at one of the country clubs in Denver. Approximately 100 attended this event, followed by an awards banquet. With this, the tradition of golf as a part of Rocky Mountain Electrical Association activities was entrenched.

Finally, on April 1, 1937, these two groups – the Electrical League of Colorado and the Rocky Mountain Electrical Association – merged and incorporated as the Rocky Mountain Electrical League. Guy W. Faller, Public Service Company of Colorado, served as the first President. Heading staff operations was George E. Lewis. The merger was accomplished for the purpose of better dissemination of information, as well as, developing greater friendship and usefulness within the industry. The Rocky Mountain Electrical League had 13 local “chapters”. 

In the early years, the League received several national awards and citations for “meritorious achievement” and was widely recognized as a pacesetter for forward-looking electrical industry activities.  

Already at this point in the Rocky Mountain Electrical League's history, hundreds of the most able executives and electrical industry representatives had given unselfishly of their time to further the objectives of the League and its predecessor organizations. Their efforts had brought innovations in merchandising, engineering and managerial practices. The belief that teamwork and intelligent planning would conquer any problem had paid off big dividends to the industry, League members and the customer.

In 1937, the first Rocky Mountain Electrical League Fall Convention was held at the Stanley Hotel in Estes Park, Colorado. The 1938 Rocky Mountain Electrical League's budget was $17,420.

In the 1940’s, the Rocky Mountain Electrical League entered into promotion programs encouraging the public to use more electricity by purchasing and using electric appliances. Washing machines, dishwashers, electric cooking ranges, air conditioners, freezers, refrigerator-freezer combinations, and electric dryers were some of the appliances promoted. 

At least four campaigns were held annually from the late 1940s to the late 1960s to promote major electrical appliances. The League’s utility members coordinated efforts with distributors and dealers. Entire sections of newspapers were given over to the promotion, in accordance with plans perfected at League headquarters in Denver. A dozen radio stations added their influence, along with the wide use of billboards.

During the WWII years, the Fall Convention was suspended, the Rocky Mountain Electrical League bought $3,000 of Defense Bonds, cooperated with the Civilian Defense Council and entered into plans to conserve and divert energy usage to defense efforts.

After the war, Labor Relations were on the front burner. Labor Relations were crucial as men returned from the war and industry ramped up. In 1945, the 40-hour workweek was becoming the standard. Linemen were making $1.54 per hour.

In 1945, Ralph Hubbard became manager of the Rocky Mountain Electrical League. During his tenure, the League expanded into New Mexico and South Dakota.

In 1947, the Rocky Mountain Electrical League allocated $28,000 of its budget to the “Go All Electric Program.” That year J.A. Bullock, Western Colorado Power Company was President. There were four Vice-Presidents from Mountain States Power Company, Public Service Company of Colorado, Public Service Company of New Mexico, and General Electric Supply Company.

Recognizing that the sale of any electrical merchandise necessitated service, Rocky Mountain Electrical League became heavily involved in appliance training programs for service technicians. The Rocky Mountain Electrical League Appliance Service Training Program thus began in 1948.

In 1949, the Spring Conference attendance was growing to the point that it now rivaled the Fall Convention. The 1950 Spring Conference was held in Denver. The registration fee was $12.00.

The Electric Meter Institute, an annual five-day training program, was re-established in 1950 and was held at the University of Denver in cooperation with the Rocky Mountain Electrical League. Prior to WWII it had been held at the University of Colorado at Boulder. It featured up to the minute developments on electric meters, their operation, maintenance and replacement. Material was presented as requested by supervisors of meter departments and others interested in the measurement of electric power. The 1950 school had 80 students.

In 1953, Guy Faller passed away. He was the first President of the Rocky Mountain Electrical League following the reorganization in 1937. 

In cooperation with the National Electrical Manufacturers Association and the Edison Electric Institute, committee members pooled resources to develop the use of major electrical appliances in rural areas of the region. An annual calendar was published, scheduling promotions for an appropriate time of the year. These included: Modern Laundry, Dishwashers, Freezers, Television and Stereo, Air Conditioning, Light for Living, Operation Snowflake, Medallion Homes, Housepower and Electrical Heating.   

The Appliance Service Program was nationally recognized in the 1960’s. Appliance Training clinics were held in nine Colorado cities and Cheyenne, WY. In 1957 a program was started to provide literature to high school students to interest them in engineering.   

The summer picnic was an annual event co-sponsored by the Rocky Mountain Chapter of the National Electrical Contractor’s Association and held at Elitch Gardens. Manufacturers, distributors, contractors and local dealers contributed a large number of prizes that were distributed through two prize drawings. Attendance usually exceeded 4,000 persons including members and their families.

In 1960, Ralph Hubbard retired and B.P. Montagriff became manager of the Rocky Mountain Electrical League.

In 1962, a contest was held to re-name the Electri-News Bulletin. The winning name was RMEL News. This became the name that remained until 2024, when the association rebranded.

Monthly luncheons were held the third Monday of each month, October through May. Outstanding speakers addressed the group on subjects directly and indirectly related to the industry. Monthly luncheons continued through the 1980’s. Heavy business time demands and changing styles doomed the luncheons.

In 1967, B.P. Montagriff retired and W.J Rosol became Secretary-Manager. The Appliance Service Training Program continued in 1970 and a slide presentation was developed on careers in appliance service for high school students. The program was available for “Career Days’" in high schools, for presentation at civic clubs or any other program to interest young people. Engineering students and professors were invited to the Spring Conference.

The Honorary Life Membership Award Program began in 1971 replacing the practice of  presenting certificates. Honorary membership in the association is conferred upon individuals, at least 55 years of age, retired from their companies. Individuals recognized shall be a person acknowledged in the electrical field, or one recognized for cooperative endeavor within the electrical industry or for long and valuable service to the League. It was decided that an honorary member shall have all the privileges of association membership except that of holding office and shall be exempt from the payment of dues.

When U.S. President Nixon issued a request for energy conservation on the part of government agencies and industry, the Christmas lighting Program was not held in 1973.

In 1974, a Rocky Mountain Electrical League committee recommended, and the Board approved, no promotion of Christmas lighting. In 1974 an Architects and Engineers Seminar was held with 275 in attendance.

In 1977 a conference was held to promote the Energy and Man’s Environment program to school district administrators and educators. The program brought to the classroom – kindergarten through grade 12 – energy related issues presented in an objective and accurate manner. Wyoming had been in the program for several years and Colorado was the seventh state to participate.

In 1983 the Architects and Engineers Seminar went on the road giving programs in Rapid City, SD; Casper, WY; El Paso, TX, and Denver, CO. The program centered around Energy Management Systems.

Also in 1983, the Production Committee was established; now called the Generation Committee. The Distribution Committee was already in existence, having started as the Underground committee. Engineering school grants for special projects were established instead of scholarships.

In 1986 a four-day Power Engineering Course was held with 44 participants.

Generation and Transmission Companies and Rural Electric Associations were approved as a membership category in 1988 and a Transmission Committee was established that same year.

The first Power Quality Seminar was held in Rapid City, SD in May 1989 with 35 in attendance. Independent Power Producers were approved as a membership category in 1990. In 1993, the Rocky Mountain Electrical League moved its offices to 2170 S. Parker Road, Suite 285, Denver, CO. Because of the changes in the relationships utilities had with their commercial and residential customers, it was determined the Architects and Engineers Seminar had served its purpose and was discontinued.

A new membership category of End User was established in 1994. Also in 1994, the Materials Management program was established with the Colorado Power Council. The first Materials Management Seminar was held in 1995 with 50 in attendance.

At the end of 1996, Bill Rosol retired and Ed Blum became Executive Director. 

In 1997, the Colorado Electric Service network dissolved and became a part of the Rocky Mountain Electrical League. 160 companies were members of the Rocky Mountain Electrial League, 37 were utilities. The Rocky Mountain Electrical League grew in individual employee memberships as Public Service Company of Colorado merged with Southwestern Public Service to form New Century Energies and then again merged with Northern States Power to form Xcel Energy. Rocky Mountain Electrical League's web site went on-line as www.rmel.org. The Safety Committee was established that year.

In 1998, the Colorado Power Council merged with the Rocky Mountain Electric League. The Customer Strategies Interest Section was established, later called the Vital Issues Committee. A group credit card processing plan was rolled out to members at discounted fees. Credit cards were accepted as payment for registrations.

In 1999, the Rocky Mountain Electrical League elected its first woman president, Jill Tietjen, University of Colorado at Boulder. The Rocky Mountain Electrical League Foundation was incorporated for the purpose of awarding scholarships to deserving and qualified students in engineering or other curriculum related to the utility industry. The underlying goal of the scholarship program was to encourage students to enter the electric energy industry. The Distinguished Leadership Award was created to honor, as merited, an individual who has demonstrated singular dedication, service, and leadership to the electric utility industry. The person must be active in the field at the time of the award. Electric Energy Magazine began publication. The Fall Convention broke the modern day attendance record. 217 companies are members of the Rocky Mountain Electrical League.

In 2000, a Silent Auction was held at Fall Convention. It has become a traditional annual event raising significant income for scholarships. The Rocky Mountain Electrical League database, grew to 10,000 records and was integrated with www.rmel.org. Event registrations were taken online. The Utility Attendance Rewards program began. Membership growth continued, as 225 companies are members of the association; 74 are utilities – a 100% growth since 1997. 

In 2001, the Rocky Mountain Electrical League's Champions program was enhanced to provide more promotional opportunities to the companies that go the “extra mile” to support the Rocky Mountain Electrical League and its programs. League Advocates were added for each company as the second-go-to-person. A Vital Issues Forum was held at Fall Convention.

In 2002, the Rocky Mountain Electrical League rolled out its third web site in five years. A library for members only featured speaker presentations from educational seminars, as well as, white papers, research, and survey information. Since the inception of the Rocky Mountain Electrical League Foundation, nine scholarships have been awarded.

In 2006 the name was changed to just “RMEL” to better represent RMEL’s growing geographic member locations across the United States.

RMEL’s development has shown that one of its strengths is diversity. RMEL is diverse in utility ownership, geography, and services across public power, municipals, cooperatives, and investor-owned electric energy companies.

In 2011, RMEL Sections and Section Education Committees were formalized for Safety, Generation, Transmission, Distribution and Management (changed to Vital Issues in 2016). 

Starting in 2020, as a result of the COVID-19 Pandemic, RMEL began adding webinar offerings to its list of educational programming, ensuring the association stayed at the forefront of education and networking, despite in-person gathering restrictions. The association continues to meet its members where they are by offering webinars in addition to its robust calendar of in-person events. 

In 2023, the NextGeneration Power Pioneer Committee was formed as a new Section Education Committee to reinforce RMEL as the influential source of professional development through networking and educational programming in support of those new to the industry and to encourage long-term career interest in electric energy.

In 2024, the association went through a rebranding initiative and officially became known as Alltricity Network. The non-profit sister organization, the RMEL Foundation, officially became known as the Alltricity Scholarship Foundation.

Formerly known as RMEL, the goals of the new name, logo, and brand identity were centered around crafting a new identity that resonates more deeply with our industry and fosters a sense of connection and collaboration among our members. "Alltricity Network" was enthusiastically selected because it instantly evokes the electric energy industry while also emphasizing the values of unity and partnership through a unique coined name.
