Frequently Asked Questions
Public Utility District #2 of Grant County's (Grant PUD's) Quincy Transmission Expansion Plan (QTEP) takes a proactive approach to managing the county's power system. QTEP includes projects that will increase electrical capacity in the Quincy area to meet future energy needs.
The purpose of the QTEP transmission line projects is to provide new path for energy to flow from Grant PUD's Wanapum Switchyard and also provide operational flexibility for Grant PUD's facilities in Quincy.
Transmission lines are key elements in the electrical system. These lines transport high-voltage electricity from power generation sources, such as Grant PUD's Priest Rapids and Wanapum hydroelectric dams, to local substations in our communities.
Most of the wood poles and power lines across Grant County are distribution lines, which deliver lower-voltage power to homes and businesses. Transmission lines carry high-voltage electricity for longer distances. They are heavier and must be strung on taller, stronger poles to ensure they don't sag too much and cause safety or efficiency issues.
Grant PUD is required to ensure that its transmission system can reliably serve customer power needs under all operating conditions, including during times of peak use (maximum demand). The proposed transmission lines will:
- Provide capacity to deliver Grant PUD hydroelectric power to growing electrical loads (i.e., demand) in Quincy
- Increase transmission system reliability
- Improve performance of Quincy's energy system
Transmission lines are heavier and must be strung higher above ground level. Their higher voltage creates more heat, which as load grows, causes the lines to sag. Transmission poles need to be taller and stronger to ensure clearance levels above ground for both safety and energy reliability.
Transmission lines, because they carry higher voltage and travel longer distances from generation sources, must also be made of thicker wires that can withstand the heat and avoid voltage drops as they stretch farther from the generation source. Voltage drop, or fluctuating voltage, is harmful to customers' electric equipment and is potentially dangerous.
Where possible, Grant PUD can install poles tall enough to carry both transmission and distribution lines, depending on the conditions.
Underground transmission lines are extremely costly to build and repair. Underground lines can cost up to ten times as much to build as overhead transmission lines, depending on terrain, environmental constraints, and other factors, The environmental impact of digging trenches to bury cable can also be significant.
Additionally, the reliability of underground transmission lines is a major question across the United States, as relatively few have been constructed other than in dense, urban settings. A problem in a buried line would take much longer to locate and repair than a similar problem in an overhead line.
QTEP consists of the following projects:
- Columbia - Mountain View 230kV Transmission Line
- Mountain View - Monument Hill 230kV Transmission Line
- Monument Hill - Rocky Ford 230V Transmission Line
- Wanapum - Mountain View 230kV Transmission Line
- Mountain View 230kV Loop #1 Transmission Line
- Monument Hill 230kV Loop #1 Transmission Line
- Monument Hill Switchyard
- Mountain View Substation Expansion
- Wanapum Switchyard Expansion
- Rocky Ford Terminal Modifications
QTEP is estimated to cost approximately $213 million. This estimated cost includes planning, public engagement, permitting, easement acquisition, material procurement, and construction.
Grant PUD commissioners have approved a policy that any needed energy demand in Grant County will be paid for by the industry that drives it. If a new industrial customer, for example, needs a new transmission line and substation, that industry will pay for those upgrades. Under the same policy, industrial customers pay above-cost for their electricity. This helps keep rates lower for residential, irrigation, ag and small and medium-sized businesses - all considered “core customers - who pay at or below cost.” The electric system requires routine maintenance and expansion as our county grows. The electric rates we charge our customers, across all rate classes, pay for these types of expenses.
Grant PUD is currently engaging with local landowners to acquire rights-of-way along the alignment to build, maintain, and operate the transmission lines. Visit our homepage to view project-specific timelines.

Steel poles will be used, and they will have a natural rust-colored finish. There will be both transmission and distribution poles and lines along the corridor. The transmission poles and lines will be about 100 feet tall, and the distribution poles and lines will be about 40 to 65 feet tall. All but a very small area around the poles can be utilized for existing uses. Irrigation canals require pole placement about 40 feet away from canals to allow access for canal maintenance. Visit our Landowner Resources page for more details on structure types.
Grant PUD has yet to propose the locations of the poles. During subsequent planning phases, Grant PUD will develop conceptual designs that will provide information such as proposed angle locations and the side of the road on which the lines could potentially be located for the selected routes. The subsequent phases of the design process will determine the requirements for new or expansion of existing easements. Visit our Landowner Resources page to learn more.
Grant PUD will negotiate directly with private property owners to acquire the necessary easements and rights-of-way. Experience shows that fair and reasonable agreements are reached after an appraisal process that takes into account the features of each particular property. It is in Grant PUD's interest to make every effort to reach agreements quickly and fairly.
Right-of-way acquisition gives permanent easement rights to Grant PUD to use the land or property to build and maintain the transmission line. Landowners are paid for the use of the land and retain ownership of the land, but they give Grant PUD permission to use the land indefinitely. If the property is sold, the new owner is bound to the terms of the easement. In most cases, Grant PUD will seek to acquire a small corridor of land, just enough to place poles on the property and for the wires attached to the poles. In addition to still owning the land, landowners can use the land except for a small area around the poles. There are some limitations to what can be placed under the lines that will run between the poles. For example, buildings or trees would not be allowed.
Right-of-way acquisition is a multi-step process that includes the following steps:
- Connecting with Individual Landowners: Grant PUD begins discussions with individual landowners by phone or in person about obtaining Right of Entry onto their lands to conduct the necessary surveys and studies, as well the process of purchasing right-of-way.
- Land Surveys and Studies: Surveyors, technical staff and engineers visit each property to identify potential pole locations and determine ground conditions.
- Appraisals: From there, with the assistance of independent appraisers, appraisals are completed to determine the fair market value of the property that Grant PUD wants to acquire easement rights to.
- Compensation Offer for Easement Rights: Grant PUD makes an offer based on appraisals by independent appraisers of like properties to establish fair market value of the easement area. Offers are typically 25- 40% of the appraised fair market value.
- Negotiating Final Agreement: Grant PUD and the landowner negotiate a final agreement for the right-of-way. Property owners may hire a professional agent to evaluate Grant PUD's offer.
As a last resort, Grant PUD may pursue a process called condemnation if an agreement cannot be reached with a landowner. Condemnation is a rarely used process under which a judge can decide whether the right-of-way is needed and its value. Condemnation is part of a government's right to acquire or authorize the acquisition of a private property for public use with just compensation to the owner. This is also referred to as eminent domain.
Except for emergency situations, property owners can generally expect the line to be accessed once a year by Grant PUD. Maintenance will be conducted if issues are observed during the assessment. Maintenance may include pruning trees that encroach in the right-of-way. In the event of an outage the line could be accessed as line crews troubleshoot the root cause of the outage.
Yes! Land within the easement may be used in ways that do not interfere with the operation, maintenance, or construction of the line. We intend to minimize impacts to agricultural operations during the design, construction, operations and maintenance of the transmission line. Since agriculture operations vary along the route of this project, we plan to work through specific land use and operational concerns with each individual property owner. Visit our Landowner Resources page for more details on right-of-way usage.
Land within the right-of-way easement may still be used in ways that do not interfere with the operation, maintenance, or construction of the line. Visit our Landowner Resources page for more details on right-of-way usage.
The effect of a transmission line project on property values can be significantly reduced or eliminated by setback distance, intervening landscaping, shielding of visual effects, and integration of the transmission line corridor into the neighborhood (trails, for example). Recent studies analyzing the effect of transmission lines on property values have concluded that transmission lines alone typically do not have a significant negative impact on property values.
EMF, which are associated with transmission lines and substations, surround us every day. They are natural consequences of our use of electricity. These fields are produced by electric ranges, lights, motors, televisions, microwave ovens, hair dryers, and all other devices that use electricity. Numerous EMF studies have been conducted during the past 30 years to determine if exposure to EMF is harmful. More than 20 scientific review panels have analyzed this body of research and concluded that none of these studies has established a cause-and-effect relationship between EMF and any harmful health effects.
There are no federal/state regulations or NESC requirements specifically limiting exposure to electric and magnetic fields.
GPS signal interference should not generally occur as a result of transmission lines. GPS devices continuously pull signals from multiple satellites—not just one. If farming equipment has a GPS unit, the equipment should work as properly when underneath a transmission line as it does when not near a transmission line. There is potential for a signal to be temporarily blocked, although the signal should come back within a few seconds as the farm equipment continues to move.
The Institute of Electronics Engineers (IEEE) previously published a white paper titled “Use of Global Positioning System (GPS) Receivers Under Power-Line Conductors,” which evaluated a similar question. The potential effects of electromagnetic interference and/or signal scattering from overhead conductors are evaluated analytically and with some practical measurements under transmission lines. Based on the analysis presented in the IEEE white paper, it is unlikely that power line conductors will interfere with use of the GPS satellite signals.
Generally, transmission lines do not cause interference with radio, television, or cellular phone signals. However, some potential interference sources do exist, including corona discharges, shadowing, and reflection.
Corona discharges occur when electric fields near an energized transmission line conductor produce small electrical discharges that ionize nearby air. The air ionization caused by corona discharges can result in the formation of audible noise and radio frequency noise. If the discharges are excessive, the audible noise can reach annoyance levels and the radio frequency noise can cause interference with radio and television reception. The potential for radio and television signal interference, however, is largely dependent on the magnitude of the corona-induced radio frequency noise relative to the strength of the broadcast signals.
Shadowing and reflection effects are typically associated with large structures, such as high buildings, that may cause reception problems by disturbing broadcast signals and leading to poor radio and television reception. Although the occurrence is rare, shadowing and reflection may occur if a transmission structure is placed between your receiver and a weak distant signal. Most reception is now digital, which allows for multiple paths to a signal and lower probability of signal interference.
The NESC is an industry standard that provides minimum line design requirements including likely wind loads in the area. Grant PUD realizes that these are minimum requirements and has many years of experience designing new lines within the area to withstand high-winds.
