1878: Railroad Commission formed

The Iowa Board of Railroad Commissioners, one of the oldest agencies in Iowa state government, was established in 1878. 

The three elected commissioners were charged with the duty of regulating railroad passenger and freight rates and operations. This oversight of the network that transported Iowans and their products was critical to pioneer farmers and businesses.

In 1911 the Iowa Legislature established the Office of Commerce Counsel, one of the nation’s first public defender’s offices, within the Railroad Commission. With the growing use of electricity, the board was authorized to regulate the location of electric transmission lines in Iowa. A rate department was added at that time, followed by statistics and engineering departments a short time later.

The agency began licensing grain warehouses in Iowa in 1921 and was authorized to regulate passenger and freight rates for intrastate motor truck transportation in 1923.

1937: Agency becomes Iowa State Commerce Commission

Authority to regulate natural gas pipeline construction was granted in the early 1930's. Because of its expanded authority, the agency was renamed the Iowa State Commerce Commission in 1937.

After World War II ended, sentiment grew for centralized regulation of public utilities. The governing bodies of the cities and towns had jurisdiction over electric and gas rates and services. The major investor-owned electric and gas companies had to deal individually with more than 200 town and city councils for each rate change. There was no provision for the regulation of communication services at either the state or municipal level. By 1953, Iowa was one of only two states that lacked a public utility commission.

In 1963 the Iowa Legislature added the regulation of the rates and service of public utility companies to the Commission’s responsibilities. Also in 1963, the commission terms were extended from two years to six years and the positions became appointed rather than elected.

The additional responsibility of regulating 923 public utilities (702 telephone companies) began to overshadow the Commission’s other duties. In 1975 the industry passed the $1 billion threshold in intrastate operating revenues, and regulation of motor and rail transportation was transferred to the Iowa Department of Transportation. Exclusive service areas for electric utilities was initiated in 1976, as well as authority to issue certificates of public convenience, use and necessity for constructing electric generating facilities.

As the price of energy rose in the late 1970's, conservation and alternative sources of energy became important issues. In 1980 the Commission was authorized to engage in several energy-saving strategies and pilot projects.

After the Iowa Legislature adjourned in 1981, only five telephone companies remained under rate regulation. Those with fewer than 15,000 customers were required only to meet the agency’s service standards.

In 1983 the nation’s first telephone deregulation statute was included in an omnibus utility reform bill that also replaced the Office of Commerce Counsel.  A state Office of Consumer Advocate (OCA) was established to represent the public interest in rate cases, and the Office of General Counsel was created to provide legal support to the Commission.

1986: Reorganization leads to Iowa Utilities Board

State government reorganization in 1986 renamed the Iowa State Commerce Commission and included the agency in an umbrella regulatory agency, the Iowa Department of Commerce. The new name, the Iowa Utilities Board (IUB), reflected the absence of the grain warehouse function that was transferred to the Department of Agriculture. Also that year, rate regulation ended for rural electric cooperatives and service regulation of municipal utilities was severely limited. The OCA was made a division of the Iowa Department of Justice.

The 1980's saw the beginning of a move away from regulation in the gas and electric industries.  In the mid-1980's the Federal Energy Regulatory Commission (FERC) began opening interstate natural gas pipelines to competitive gas suppliers. Congress fully deregulated sales of natural gas, but the interstate transportation of natural gas was still regulated by FERC. As a result, gas could be obtained competitively at hundreds of delivery points in Iowa.

Since the late 1980's, industrial customers in Iowa have been purchasing gas in the open competitive market, but small-volume customers faced continued barriers. In August 2000, the IUB required each rate-regulated natural gas utility to file draft tariffs to implement transportation to small-volume end-users.

In 1989 the Iowa Legislature abolished the practice of the IUB and the OCA utilizing shared technical staff. The IUB also was given authority to oversee mergers and acquisitions of utility companies. The 1990 Iowa Legislature, at the IUB's urging, gave the IUB authority to oversee gas and electric utilities’ energy efficiency activity.

Telephone price regulation was authorized in 1995 along with laws encouraging the development of local telephone competition. The Federal Telecommunications Act of 1996 opened the local telecommunications market to competition and gave state commissions the authority to determine prices for the use of the telephone network.

With Executive Order Eight in 1999, the Governor asked all state agencies to review their rules for need, clarity, intent and statutory authority, cost, and fairness. In February 2000 the IUB issued its plan for regulatory review. After receipt of public comments, staff teams developed recommended changes to the IUB's rules. During 2001, the IUB submitted its recommended rule changes to the governor in its assessment report. In April 2001, the IUB implemented new rules establishing the criteria for certification of competitive natural gas providers. The rules allowed certified competitive natural gas providers to pool transportation service to Iowa small-volume business and residential customers for the first time. The large-volume competitive natural gas providers that served Iowa industrial customers previously continued providing service but became certified under the new rules.

The electric industry was also changing. The Federal Energy Policy Act of 1992 (EPACT) permitted independent power producers to enter the wholesale power market, where they could sell electric capacity and energy to utilities at unregulated market rates. EPACT also authorized FERC to require electric utilities to open their transmission systems for wholesale transactions. The apparent success of competition in the wholesale electric market led to growing pressure to allow retail competition as well. The Legislature considered electric competition proposals in 1998, 1999, and 2000, but nothing was enacted. In September 2000, after the California energy crisis, the governor announced the formation of a task force to take a comprehensive look at Iowa’s energy needs.

Also in 2000, the IUB initiated an inquiry into electric delivery reliability and an investigation into generation resource planning, which continued in 2001. In December 2001, the IUB released a report entitled, “Report on Electric Delivery Reliability Inquiry, A Staff Analysis, Docket No. NOI-2000-0004.”

In 2001 the Iowa Legislature adopted House File 577 to attract the development of electric power generating and transmission facilities in the state. The new legislation streamlined the statutory generation siting requirements and allowed advance ratemaking principles for the construction of certain generation plants built by rate-regulated utilities. It required the IUB to establish ratemaking principles that will apply when new plant costs are included in electric rates. Utility companies were previously required to wait until new plants actually went on line before learning how regulators would treat their investment.

In 2002 the IUB was given discretion to reduce the filing requirements to streamline petitions for extension of electric franchises.  Also in 2002, the state’s Interagency Missouri River Authority was established to represent Iowa interests regarding membership in the Missouri River Basin Association. The IUB was named a member agency. The interagency group is charged with promoting the management of the Missouri River in a manner that does not negatively impact landowners along the river or the state’s economy.

In 2003 the IUB became a founding member of the Organization of MISO States (OMS). OMS is a nonprofit, self-governing organization of representatives from each state with regulatory jurisdiction over entities participating in the Midwest Independent Transmission System Operator, Inc. (MISO), a regional transmission organization as defined by FERC. OMS coordinates regulatory oversight among the states, including recommendations to MISO, the MISO Board of Directors, FERC, other relevant government entities, and state commissions as appropriate.

In 2004 and 2005, the IUB deregulated the rates for local telephone service in a total of 40 Iowa exchanges where it made a finding of effective competition. The IUB continues to regulate service quality in these exchanges and monitors the markets. The IUB initiated the rate deregulation proceeding after conducting a statewide local telecommunications competition survey, which indicated specific geographic areas or certain customer groups had a choice of service providers.

In 2005 legislation removed price controls from all local telephone service in Iowa except the most basic single-line residential and business services of Iowa’s large incumbent local exchange carriers. Previously, these carriers had been fully price regulated. The IUB continued to price regulate the incumbent carriers’ basic services during a projected three- to five-year phase-out period. A portion of the proceeds from any single-line increases during the transition period were required to be used to install high-speed Internet service in rural areas. The law also enabled local exchange carriers to file complaints with the IUB against other local exchange carriers they believe have engaged in anti-trust activities. The IUB could order a local exchange carrier to adjust its retail rates and assess a civil penalty.

In 2005 Iowa enacted legislation creating two separate production tax credits for electricity generated by eligible renewable-energy facilities. The credits are subject to approval by the IUB. Iowa Code chapter 476C created a production tax credit of 1.5 cents per kilowatt-hour for electricity generated by and purchased from eligible wind and other renewable-energy facilities, including biomass and solar. Iowa Code Chapter 476B created a production tax credit of one cent per kilowatt-hour for electricity generated by and purchased from eligible wind-energy facilities. The IUB adopted final rules on the facility eligibility process in Docket No. RMU-2005-0008. The tax credits are issued and tracked by the Iowa Department of Revenue.

In April 2006 the IUB approved more uniform Interstate Power and Light Company (IPL) class rate structures and rate changes, moving closer to equalizing electric rates across IPL’s four electric service territories in Iowa. Rate disparities resulted from past mergers and acquisitions of utilities that had varying rate structures. In deciding the company’s previous rate case (Docket No. RPU-2004-0001), the IUB established a flexible target for equalizing rates over a five-year period for residential and commercial customer classes and a three-year time frame for large commercial and lighting customer classes.

In July 2006 the IUB commenced a multi-layered energy efficiency initiative in Iowa. A component of this was the Iowa Weatherization Challenge, in which the IUB works with local community agencies across Iowa to recruit volunteers and solicit donations to help weatherize homes for Iowa’s low-income families, elderly, and disabled individuals. The IUB also began investigation and reassessment of various policies, rules, legislation, and utility energy efficiency programs as well as evaluation of the use of new and emerging technologies.

The energy efficiency push extended to the national level. In 2006 a National Action Plan for Energy Efficiency was unveiled. Iowa was instrumental in forming this national energy-saving plan under the leadership of the Board Members. Its numerous recommendations elevated the importance of energy efficiency as part of the work of utility regulatory bodies. The recommendations build upon the best existing practices from successful efficiency programs to remove barriers that had traditionally limited utilities and customers from pursuing cost-effective energy efficiency resources.

Legislation passed in 2007 required that providers of cable or video service acquire a franchise either from the IUB or a municipality.  The new statute and rules did not give the IUB regulatory authority over cable service.

Pursuant to Iowa Code, on June 27, 2008, the IUB issued a decision order finding that sufficient market forces existed throughout Iowa to constrain the price of single-line, flat-rated residential and business rates in general. The record also showed that competitive offerings from competitive local exchange carriers, wireless carriers, and cable providers were available in much of the state and most Iowa consumers had a choice of telecommunications service providers. Therefore, effective July 1, 2008, the IUB no longer held retail rate jurisdiction over single-line, flat-rated residential and business service rates of local exchange telecommunications carriers in Iowa.

In January 2009 the IUB implemented its new online electronic filing system (EFS). The paperless filing process enables the public to view most case documents filed in IUB proceedings online.  Working with a vendor, IUB staff designed and tested EFS, including training of internal and external users. An EFS Help Desk was also established. Now referred to as IT Support, you can reach staff via the following contacts:

On January 18, 2011, the IUB and OCA moved into a new model energy efficiency office building located on the State Capitol Complex at 1375 E. Court Ave. (East 14th Street and Court Avenue). The building demonstrated cost savings, energy reduction, and environmentally friendly features and ideas. Architects for the project were BNIM Architects of Des Moines. The contractor was J.P. Cullen and Sons of Janesville, Wis. The State sought and was granted the highest certification, LEED Platinum, from the U.S. Green Building Council. 

On April 28, 2011, a building open house ceremony and public tours were held and then-Governor Terry Branstad presided at the event. Iowa’s Consumer Advocate, Mark Schuling, said the building "demonstrates the benefits of cost-effective energy efficiency programs." The 44,460-square-foot building was anticipated to use about 63 percent less energy than a typical office building of the same size, saving about $36,000 a year. Geothermal heating and cooling technology would account for the largest share of the energy savings. Other energy efficient features include super-efficient precast concrete wall panels with integrated edge-to-edge rigid insulation, daylight harvesting solar screens and a V-shaped design to make maximum use of daylight, lighting and occupancy sensors, special plug outlet controls, and operable windows for use on temperate days. Roof-mounted solar energy panels were projected to provide about 12.5 percent of the total energy used. An energy information kiosk for use by visitors and employees was installed in the building’s entrance lobby in 2011. The kiosk provides updated energy efficiency facts as well as detailed solar generation and energy consumption data pertaining to the energy-saving State office building.

The IUB and OCA continue to conduct public tours focusing on the energy efficiency aspects of the office building. Participants have included individuals from utilities, utility industry groups, colleges and universities, architects, and other interested organizations.

In 2020 the IUB launched IUB 24/7, an always-available web application that allows companies, utilities, and individuals that interact with the IUB to manage and update their individual and company information, provide contact information, and file annual reports. Telecommunications companies file required registration information and Dual Party Relay Assessment reports in IUB 24/7.

2023: Reorganization establishes IUB as a stand-alone agency

State government reorganization in 2023 removed the IUB from the umbrella regulatory agency of the Department of Commerce and established the IUB as an independent, stand-alone agency.
