Book Cliffs Power Transmission
Priority Project of the Seven County Infrastructure Coalition
The corridor for proposed 138 kV electrical transmission line is located between the Bonanza Generation Station south of Vernal to Upalco and Duchesne substations, and parallels existing power transmission facility. The proposed construction of 2 miles of power line serves as a backup to feeder 2 out of the Ft. Duchesne substation. This feeder serves homes, irrigation facilities, and oil wells in portions of T3S R2E, T2S R2E, and T2S R1E. Over 140 meters are served out of this feeder.
In recent years there has been an increase in electrical load growth in the Uintah Basin. The reliability of electrical service to many current electrical users, both residential users and commercial users, is currently at risk. In addition, there isn’t capacity to reliably serve additional customers already located in the area. As a result, alternatives to electricity, such as propane, waste natural gas and diesel, are being used. This causes higher levels of air pollution. In 2014, a joint transmission study conducted by Rocky Mountain Power, Deseret Generation and Transmission, and Moon Lake Electric Association (MLEA), show that all available electrical transmission capacity may be used up within the next couple of years.
The existing lines serving this area are considered “skinny” or extremely undersized facilities. In short, the reliability of electrical services to current customers in the Basin is at risk.
If this line is not constructed, communities in Uintah and Duchesne Counties will face a significant number of prolonged outages (brown-outs). In 2014, there were 7 outages that could have resulted in prolonged loss of power if loads were at projected levels. Communities subject to prolonged outages include: Roosevelt, Fort Duchesne, Neola, White Rocks, LaPoint, Duchesne, Altamont, Tabiona and surrounding communities.

The Seven County Infrastructure Coalition is a public implementation and ownership entity that allows its members to build essential regional infrastructure elements that span across county lines. The Coalition’s main roles are to identify revenue-producing infrastructure assets that will benefit the region. Its mission is to plan infrastructure corridors, procure funding, permit, design, secure rights-of-way and own such facilities.
