Overview

Intermountain Power Project (IPP) power plant near Delta, Utah, is owned by the Intermountain Power Agency, a consortium of cities that includes Los Angeles, through its Department of Water & Power.

The following comes from "Economic and Fiscal Impacts of the Intermountain Power Project," prepared for the Intermountain Power Agency by the Bureau of Economic and Business Research, Graduate School of Business, University of Utah, April 1, 1985:

The Intermountain Power Project (IPP) is one of the major construction projects of the 1980's in the Intermountain West. It is a 1,522 megawatt, coal-fueled power generating facility located in west central Utah which will provide electrical power to southern California through a 500 kilovolt (kV) direct current transmission system. Power will also be supplied to Utah and Nevada through a northern transmission consisting of two 345 kV lines to Mona, Utah, 46 miles east, and one 230 kV line to Gonder, Nevada, 144 miles west. (Gonder is six miles north of Ely.) The Project is expected to cost $5.5 billion ($3.342 billion with financing costs excluded). Commercial operation for the first unit is scheduled for July, 1986, and completion is set for July, 1987.

The owner of IPP is the Intermountain Power Agency (IPA), a political subdivision of the State of Utah organized under the Interlocal Cooperation Act, Title 11, Chapter 13 Utah Code Annotated 1953, as amended. IPA was formed by 23 municipalities within Utah to own and finance IPP. The project has been financed with tax-exempt revenue bonds, using as collateral power sale contracts between IPA and 36 power purchasers located in Utah, Nevada, and California.

Intermountain Power Agency is a separate legal entity and a political subdivision of the State of Utah and was organized in June 1977 as a result of The Utah Interlocal Co-operation Act and under the Intermountain Power Agency Organization Agreement, dated May 10, 1977. IPA was organized for the purposes of undertaking and financing a facility to generate electricity, now known as the Intermountain Power Project. As authorized by the Act, the membership of IPA consists of 23 Utah municipalities that own electric utilities. All member entities are located within the State of Utah and are as follows. (Intermountain Power Agency, About Us)

The list of participants in IPA include six California cities, owning 75 percent; 23 Utah cities, owning 14 percent; six Utah cooperatives, owning 7 percent, and Utah Power (now Rocky Mountain Power) which owns 4 percent. (Intermountain Power Agency, About Us)

From Jim Harrawood's defunct UtahRails.com web site:

The concept for the Intermountain Power Project began in 1970 when the Intermountain Consumer Power Association (ICPA) was notified by the Federal government that there would not be sufficient energy available to meet its needs from the Colorado River Storage Project after 1976. Following this notice, ICPA began considering alternatives for future resources and in 1973 met with a number of Southern California municipalities to explore interest in a joint action agency power project.

As a result of these activities, the Intermountain Power Project Corporation was formed as a non-profit corporation under the laws of the State of Utah on January 18, 1974 for the purpose of investigating the feasibility of constructing and operating a thermal powered generating resource. Shortly thereafter, in July 1974, ICPA and the California Purchasers entered into the IPP Membership and Study Agreement, setting forth membership interests and voting rights in IPP. In March 1977, the Utah State Legislature amended the Act to allow municipalities to jointly develop electric generating facilities, and on June 22, 1977, the 23 Utah municipalities listed above organized IPA as a political subdivision of the State of Utah to finance, construct and operate the Project.

Approximately one year later, on August 24, 1978, Power Sales Contracts were offered and in response the 23 Utah municipalities, six Utah cooperatives, Utah Power & Light Company, and six California municipalities agreed to accept the generation and capacity of the Project. The Power Sales Contracts were signed as of September 28, 1978 with the exception of the California Purchasers which signed as of August 6, 1980. The Power Sales Contracts provide for, among other things, the creation of the Coordinating Committee and for IPA and the Los Angeles Department of Water and Power (the "Department") to enter into a Construction Management and Operating Agreement.

The three main components of the Project are located primarily in Utah and California. The Generation Station is located near Lynndyl, Millard County, Utah. The STS extends approximately 490 miles from the Generation Station to Adelanto, California with an alternating current/direct current converter station at each end. The Northern Transmission System (the "NTS") consists of two segments. The first segment, consisting of two parallel 345-kV AC transmission lines, extends approximately 50 miles from the Generation Station to a switchyard located near Mona, Utah. The second segment, consisting of a single 230-kV AC transmission line, extends approximately 144 miles from the Generation Station to the Gonder Switchyard located eight miles north of Ely, Nevada.

The West Ridge Project consists of the West Ridge Mine which is now under development in the Book Cliffs coal region in central Utah near East Carbon. The project is owned on a 50/50 basis by Intermountain Power Agency and ANDALEX Resources, Inc. It is being developed and will be operated by West Ridge Resources, Inc., a wholly owned subsidiary of ANDALEX Resources, Inc. ANDALEX will also be responsible for the marketing of the production. West Ridge will be a longwall mining operation with full production planned for the year 2001 at the rate of 3.5 million tons per year.

A portion of the coal used is loaded at the Andalex Loadout located at Wildcat, UT on the Utah RY. IPPX has their own unit train hoppers.

From Utah Geologic Survey:

The Intermountain Power Agency (IPA) and its Intermountain Power Project (IPP), located just north of Delta, Utah, were created in 1976 to meet the power needs of some 23 public agencies and municipalities in Utah. The Los Angeles Department of Water and Power is the operating agent, as nearly all IPP power is exported to 27 California municipalities until such time as Utah allotments are called in to meet in-state demand.

As of April 2004, IPP increased its capacity rating to 1,800 MW, making it the largest power generation facility in Utah. In 2003, IPP generated a net of 13,553 GWh of power and purchased 5.3 million tons of Utah coal, the majority of which came from Canyon Fuel mines. The remaining amount of coal was supplied by the Andalex mines, two of which are partly owned by IPA. In addition, a small amount of coal was purchased from the Emery mine before it became idle in August 2003.

Plans for expanding IPP by adding a third unit would increase generation capability by another 950 MW in 2009. This additional capacity is intended to supply power to communities in Utah, New Mexico and Arizona. Coal consumption would rise almost 40 percent with such an expansion. This new demand is expected to be met mostly by Utah coal, particularly from the mines jointly owned by IPA and Andalex. (Documenst on file at Utah Geologic Survey)

Coal for IPP was to be supplied by mines in Carbon, Emery, and Sevier counties, coming from the mines of U. S. Fuel Co. (King and Mohrland mines), Getty Minerals Co. (Skyline mines no. 1 and 2, and Star Point mines no. 1 and 2), Tower Resources, Inc. (Centennial project), and Coastal States Energy Co. (SUFCO mine no. 1) Coal was to be delivered by truck and by rail. (IPA news release, dated July 2, 1985)

In 1990 the Intermountain Power Agency (IPA) acquired the Geneva coal mine in Horse Canyon in Carbon County from Kaiser Coal Company, along with the adjacent South Lease Coal Reserves. In 1990-1991 IPA reclaimed major portions of the Geneva mine's surface mining facilities.

In October 2004, Canyon Fuel's Skyline Mine shut down, causing coal supply problems for IPP:

Timeline

The following timeline was taken from the 2011 IPP Annual Report, pages 4-8.

1957
The Utah Cooperative Association begins exploring methods to secure low cost hydroelectric power from the Colorado River Storage Project. The Intermountain Consumer Power Association (ICPA) is formed to provide direct support for acquiring the power.

1970
The U.S. Bureau of Reclamation notifies ICPA that expected energy resources from federal dams would not meet projected ICPA load growth requirements after 1975. ICPA begins investigation of alternative sources of power for future requirements.

1973
ICPA representatives meet with Southern California municipalities to identify interest in the development of a joint action power project.

1974
The Intermountain Power Project is formed as a nonprofit corporation under Utah law to investigate the feasibility of constructing and operating a thermal power generating plant and associated facilities. The Project is joined by ICPA and six southern California cities. Salt Wash near Caineville, Utah, in Wayne County is recommended as the primary study site.

1977
The Utah State Legislature amends the Utah Interlocal Cooperation Act to allow municipalities to jointly develop electric generating facilities. Twenty-three Utah municipalities organize the Intermountain Power Agency as a political subdivision of the State of Utah to construct and operate the Intermountain Power Project. Utah Governor Scott M. Matheson, after conferring with Interior Secretary Cecil Andrus, directs the formation of an Interagency Task Force on Power Plant Siting to consider alternate sites for IPP. The task force recommends an alternative site near Lynndyl, in Millard County.

1978
IPP authorizes engineering and environmental studies necessary to incorporate the Lynndyl Alternative Site into the IPP Environmental Impact Statement. Power sales contracts are entered into with 23 municipalities, six rural electric cooperatives and Utah Power & Light Co. IPA adopts the Power Supply Bond Resolution.

1979
Interior Secretary Andrus announces approval of the Lynndyl Alternative Site for construction of the Intermountain Power Project.

1980
IPP acquires surface and underground water from five Millard County irrigation companies. Consulting engineers are retained. Power sales contracts are entered into with six southern California municipalities. The Los Angeles Department of Water and Power is designated Project Manager and Operating Agent. Assets of the Intermountain Power Project are transferred to IPA. The IPP Board of Directors is dissolved and the IPP Coordinating Committee is formed.

1981
Millard County approves a permit allowing construction to begin. $300 million of initial project capital funding is received from the sale of 1981 Series A Bonds. A groundbreaking ceremony is held on October 9 in Delta, Utah, and at the Project site.

1982
Bechtel Power Corporation is approved as Construction Manager and installation of structural concrete begins. A Project Operating and Maintenance Plan is adopted, establishing the Intermountain Power Service Corporation. Coal supply contracts are executed with two Utah mines.

1983
Structural steel erection commences. IPA issues $900 million in 1983 Series A Bonds -- representing the largest joint action agency financing in history. Coal supply contracts are executed with four more Utah mines. The Unit 1 steam drum is lifted into position.

1984
Installation of wire and cable begins. A groundbreaking ceremony is held in Springville, Utah, for construction of the IPP Railcar Service Center. A contract is executed with Union Pacific Railroad for coal delivery. Initial project financing of $4 billion is completed by IPA.

1985
First scheduled coal train arrives at the Project site. Unit 1 boiler is fired. Construction of the Southern and Northern Transmission lines is completed.

1986
Turbine roll of Unit 1 is initiated in February and the Unit is declared commercially available in June. The First Generation Celebration commemorating the completion of Unit 1 is held at the Project site on September 10.

December 19, 1979
The site of the new Intermountain Power Project near Delta, Utah, was announced. The following comes from the Eugene Register-Guard newspaper, December 21, 1979.

Andrus approves new power plant in Utah desert -- Salt Lake City (UPI) -- Interior Secretary Cecil Andrus has approved a location In Utah's western desert as the site for the world's largest coal-fired power plant -- a 3,000 megawatt giant that will provide electricity for Los Angeles County and dozens of small cities in Utah and Nevada. In a speech to the Intermountain Power Association Wednesday night. Andrus sanctioned a site near Lynndyl. Utah, ending two years of dispute over possible locations for the $4.5 billion Intermountain Power Project. At full production, the facility will generate daily as much electricity as Utah consumes in a year. Fifty-eight percent go to Los Angeles and five of its suburbs. It will also consume nine million tons of coat annually, an amount equal to Utah's current total coal production.

August 17, 1981
Bechtel was selected as the management contractor for the Intermountain Power Project. Politicians from California and Utah got involved, strongly suggesting to members of the Intermountain Power Agency board that the other two companies, of the three companies originally being considered (Bechtel of California, Daniels of South Carolina, and Jelco of Utah) be given a second look. Intrigue and editorials followed concerning political contributions to each of the parties involved, including complaints to the Federal Elections Commission. On September 2, 1981, the IPA board reaffirmed its selection of Bechtel.

October 9, 1981
A ground breaking ceremony was held at the site of the Intermountain Power Project coal-fired power plant near Delta. (IPP Annual Report 2011, timeline on page 6)

A contract was signed with Bechtel as the overall construction management contractor for the entire Intermountain Power Project. (Deseret News, November 24, 1981)

June 17, 1985
The first coal train bound for the Intermountain Power Project operated over Utah Railway, and had been loaded at the new flood loader at Wildcat. (Pacific RailNews, Issue 262, September 1985, page 4; CTC Board, August 1985, back cover, two photos of first train)

July 2, 1985
The first scheduled coal delivery took place for the IPP site near Delta. Over 300 people attended a ceremony that commemorated the event. (The author was asked to attend this event, after providing a photo to IPA of the recently acquired SW1000 locomotive purchased to switch rail cars at the Springville car shop.)

September 1985
"Coal Delivered -- The first deliveries of coal for the 1,500-Mw Intermountain Power project in central Utah have started to provide fuel to test the first 750-Mw unit and to stockpile for the start of commercial operations in July 1986. The second unit is scheduled to come on line in July 1987. Tower Resources, operator of an underground mine near Price, Utah, suplied 10,000 tons of coal for the first 84-car unit train delivery. Coastal States Energy Co., another supplier for the plant, supplied its first 84-car train delivery two weeks later. The plant will consume 4.4 million tpy (tons per year) when both units are in operation." (Coal Age, Volume 90, Number 9, September 1985, page 57)

September 16, 1985
The transmission line between Utah and California was completed. The following comes from the Davis County Clipper newspaper, October 3, 1985.

Transmission Line Completed On Time -- Right on schedule, to the exact day, the Intermountain Power Project's (IPP) 490 mile transmission line from Utah to California was completed.

The line, which was started May 1, 1984 was completed Monday, Sept. 16. The final spans of wire were attached at the towers and racks by the two contractors who divided construction of the line, Commonwealth Electric Company of Marietta, Georgia, and Irby Construction of Jackson, Mississippi.

IPP's site manager for the transmission line, Mike Pontius, attributed the timely completion to the quality of the supplies, the contractors, and the work force. "Completing this large and complex project on schedule is a tribute to a productive work force and excellent contractors," he said.

The contractors employed 600 workers to construct the line, about 300 each. Commonwealth constructed the 239 mile portion from Adelanto, California, to Moapa, Nevada. and Irby constructed the 250 mile portion from Delta to Moapa. Except for the initial tower survey, the contractors were responsible for all phases of the construction.

The first phase involved cutting the access roads. The second phase was the excavation and construction of the footings of the steel towers. The footings were poured to an average depth of 20 feet and varied in diameter depending on the steel tower height and weight. Some of the excavation involved blasting through rock structures.

March 1986
The Intermountain Power Agency, operators of the Intermountain Power Project near Delta, Utah, purchased the entire Mohrland coal field from United States Fuel Company. The following comes from the Deseret News newspaper, March 27, 1986.

Power agency buys coal reserve in Emery to fuel plant near Delta -- The Intermountain Power Agency has purchased a 35-million ton coal reserve in Emery County to fuel its 1,500 megawatt electrical generation plant near Delta.

IPA purchased the Mohrland coal field from United States Fuel Co. for $28 million, IPA spokeswoman Ann Garrett said.

The agreement alters a previous contract between IPA and United States Fuel, which called for the purchase of a certain tonnage of coal from the Mohrland mine.

Garrett explained the new agreement benefits both parties by offering United States Fuel an immediate cash payment for its coal, while allowing IPA to determine the amount of coal it uses at the plant and leaving an option open to sell excess coal from the reserve.

The Intermountain Power Project electrical generation plant will use an estimated 4 million tons of Utah coal annually, she said.

IPA has previously signed other agreements to purchase coal from Utah mines operated by Coastal States Energy, Tower Resources and Cyprus Minerals.

The $5.8 billion power plant project is near completion, Garrett said.

Operating tests are being run along IPP's northern transmission lines and and the first commercial power generation is scheduled in or before July. The plant's two, 750-megawatt generators will be in full operation by July 1987.

More than 75 percent of the electricity generated from the plant will be delivered along 590 miles of transmission lines from Delta to southern California.

Six California communities have purchased power shares In the project along with 23 Utah municipalities, five Utah cooperative utilities, Utah Power & Light and a Nevada cooperative.

The project has been praised by local government officials and economists as one of Utah's largest industrial undertakings, employing more than 4,500 workers in 1985.

Commercial operation of unit 1 started in June 1986, and unit 2 in May 1987. (Intermountain Power Agency, About Us)

(IPP's second unit went on line on June 13, 1987)

Rail Operations

Intermountain Power Project No.1 (EMD Model SW1001, builder number 847004-1, builder date April 1985) will be used by IPP at their Springville Rail Car Facility located at Springville, Utah (50 miles south of Salt Lake City) to 84 car unit-trains (from a recently delivered 285 car order of all-aluminum Ortner 4-bay, rapid-discharge open-top hopper cars, each with a 103 ton capacity). Trains are originating at mines located on D&RGW's Pleasant Valley Branch and the Hiawatha and Wattis Mines located on the Utah Railway, all in Utah's Carbon County. Both D&RGW and Utah Ry. have trackage rights through Union Pacific's Provo (Utah) Yard to the IPP's facility at Springville, which is located within the newly extended yard limits of the Provo Yard to allow switching of the unit trains by the road crews of all three roads. UP will then transport the assembled trains from Springville south to IPP's coal-fired power plant located near Lynndyl, Utah, where they will be unloaded automatically while traveling around a balloon track. The empty trains will then return to Springville where they will be broken up and the cars returned to the various mines for reloading. The new service is slated to begin during the first week of July 1985. (Don Strack, report dated May 31, 1985)

IPA operates several unit coal trains in Utah, along with a rail car repair facility in Springville, Utah. At the Springville facility, IPA uses an EMD SW1001 switcher to shuttle rail cars around and within the repair facility. During March 2007, IPP (AAR reporting mark IPPX) took delivery of at least 70 new rail cars, numbered as IPPX 1001-1070.

Ryan Ballard wrote this about IPP's unit coal train operations:

Utah Railway does not take the train all the way to the power plant near Lynndyl. The train is turned over to the Union Pacific at Provo. UP takes the train from Provo down the Lynndyl Subdivision to Lynndyl. At Lynndyl is the track to the power plant where the train is unloaded on a balloon track. The empty train then returns to IPP's yard at Springville, where it is inspected. All IPP trains start and end at their Springville yard.

BNSF does not have anything to do with the IPP train. It is a UP and Utah Railway train.

The UP track that this train goes south on (railroad west) lays east of the IPP yard in Springville. Anything going north goes to Salt Lake City.

Train crews change in the UP yard in Provo. The IPP yard is where the trains are stored and checked out. All IPP trains leave the Springville yard to go to the mine load outs. Both Utah crews and UP crews work out of the IPP Springville yard. Also at IPP's Springville yard is car storage, train storage, and a car shop for car repairs. This shop repairs both IPP cars and other company's cars.

IPP does get some coal from Wyoming and Union Pacific runs these trains, but at present I'm not sure were the Wyoming trains are loaded.

Power for the IPP train train is both Utah Railway MK50-3's and UP AC units, both GE and EMD. Utah will use UP engines if their own power is on the east end of their line. If UP is short of power in Provo, then the Utah Railway's motive power will run to the power plant with the train.

June 17, 1985
The first coal train bound for the Intermountain Power Project operated over Utah Railway. (Pacific RailNews, Issue 262, September 1985, page 4; CTC Board, August 1985, back cover, two photos of first train)

The train was a joint operation of Union Pacific and Utah Railway, and was loaded at the Wildcat loadout on Utah Railway. The first train had 84 cars and operated without a caboose. Its main motive power was four UP GE locomotives, including UP 2436, 2457 and 2462. Its trip up the east side of Soldier Summit used four Utah Railway ex-BN F45s and two of the four ex-SP SD45s being tested in the new service.

[photo caption] This is the first train from the Wildcat mine near Martin, Utah (on the Utah Railway) to the new Intermountain Power Project near Delta, Utah moving on June 17, 1985. This particular train is scheduled to run about six times per month until the new power plant gets into full stride when it will require three trains of coal per day from various Utah mines. Above, the train, using UP power (it is a joint UP/Utah Railway operation) and new aluminum cars, is dropping around the middle Gilluly loop below Rio Grande's Soldier Summit. The photo below shows the same train on the 2.4 percent Price River grade near Castle Gate. The helper on the 84 car cabooseless train is four ex-BN F45's, now with Utah Railway stenciled on the sides, plus two of the SP SD45's (of a group of four) now being used on a trial basis by the Utah. The train speed, even with all this power, is about ten miles per hour. (CTC Board, August 1985, back cover)

July 2, 1985
A special ribbon-cutting ceremony was held at the IPP plant, labeled as the "First Train." The ceremony included tours of the facility and a luncheon for dignitaries.

July 2, 1985
The first scheduled coal delivery took place for the IPP site near Delta. Over 300 people attended ceremony that commemorated the event. IPP's Unit was was scheduled to be completed within a year, and was 87 per cent complete at the time of the coal delivery. The annual coal requirement was reported to be 4.4 million tons, with a daily requirement set at 12,000 tons. Coal was to be supplied by mines in Carbon, Emery, and Sevier counties, coming from the mines of U. S. Fuel Co. (King and Mohrland mines), Getty Minerals Co. (Skyline mines no. 1 and 2, and Star Point mines no. 1 and 2), Tower Resources, Inc. (Centennial project), and Coastal States Energy Co. (SUFCO mine no. 1) Coal was to be delivered by truck and by rail. The rail cars will be serviced at the newly completed Springville Railcar Service Center. Ortner Car Company built the 182 cars being used, each with a capacity of 103.4 tons, and has an option for an additional 91 cars. (IPA news release, dated July 2, 1985)

May 2012
In a complaint filed in May 2012 with the federal Surface Transportation Board, concerning UP's transportation rates between the interchange with Utah Railway at Provo, and the IPA power plant near Lynndyl, the Intermountain Power Agency stated that the capacity of IPA power plant was 1,800 MW and consumed 4 million to 6 million tons of coal per year. The IPA also stated that it planned on shipping at least 2.5 million to 3.5 million tons of coal per year from the Provo interchange through the end of the upcoming 10-year period. The remaining 2.5 million tons would be shipped from other locations, and by other means of transportation, which might include both rail and truck. (Barry Cassell, GenerationHub, May 31, 2012)
