Wanapum-Mountain View 230 kV Transmission Line Project
The Wanapum-Mountain View Project is the biggest and most important project in QTEP because it provides a new connection to the source of our region's power, the Wanapum Dam. The new transmission line will make it possible to distribute more electricity to our customers from the Mountain View Substation in Quincy.
Project Location
This new 31-mile-long line will be built primarily along existing roadways, mostly along Beverly Burke Road south of I-90 and will replace an existing transmission line north of I-90.
The southern portion will be built along the same alignment as an existing distribution line, whose lines will be relocated on to the new transmission poles.
Quick Facts
- Anticipated Construction Start: 2028
- Anticipated Construction Completion: 2029
- Estimated Cost: $86 Million*
We're Listening
Grant PUD evaluated four alternatives for the new transmission line in 2022-2023 and presented them to the public at an April 23, 2023 open house.
Grant PUD selected the current route (known as alternative 4b) primarily because it:
- Uses existing roads, which are more accessible than cross-country routes
- Avoids sensitive federal and state lands, which would have required more extensive environmental permitting and lead to construction delays.
We heard and acknowledge concerns about the selected route because it crosses private property. We understand.
As a public utility, we have roots in the community and we are committed to working with property owners to ensure they are made whole through this process. We are here to share information that is accurate and timely and most importantly, to listen.

The PUD owns and operates the Priest Rapids and Wanapum dams on the Columbia River and the high voltage transmission lines that help deliver electricity to our customers. The new Wanapum-Mountain View Transmission Line will be a critical resources for this region.

Project Schedule
Starting in 2022, Grant PUD began reviewing alternatives for the new transmission line. Public meetings were held in 2022 and 2023 to present alternatives to the community. Beginning in late 2022 through present day, we performed an environmental review of the proposed route, submitted permit applications, and started working with landowners to obtain easements to build, maintain, and operate the new transmission line.
We anticipate starting pre-construction activities (like materials procurement) in mid-2026 with construction beginning in mid-2028. Service of the line is expected to begin in late 2029.
