What is the R-Project and what are the benefits?
The R-Project is a new 345,000-volt transmission line that will run from NPPD’s Gerald Gentleman Station near Sutherland, Nebraska connect to a substation near Thedford, Nebraska and then continue east to a substation in Holt County. This 226-mile line is an important investment in Nebraska’s energy future — improving reliability of the electric grid, relieving congestion on existing transmission lines, and providing opportunities to connect any type of new generation, including renewables. See the map for more details.
Why connect at Thedford?
For the R-Project, adding facilities to an existing substation to meet transmission network reliability or customer electrical energy delivery needs is the most cost-effective solution. Additionally, the Thedford 115,000-volt substation is at the midpoint of the west leg of the 115,000-volt transmission network serving north central Nebraska and is centrally located with respect to the termination points of the R-Project transmission line.
What is NPPD doing right now to keep electricity reliable until the R-Project is complete?
Until the R-Project can be completed, NPPD has had to put interim actions in place to maintain service for all customers. These interim actions are less reliable and more expensive for our customers over the long term and include:
- Shifting power flows to reduce stress on the most vulnerable parts of the system
- Adding temporary backup resources like mobile generators and equipment to support local power needs
- Strengthening the grid by upgrading equipment and reconfiguring the system to improve stability
- Building new infrastructure such as a substation with additional voltage support
What is SPP's role in the R-Project?
NPPD is a member of the Southwest Power Pool, a regional transmission organization that oversees reliability across several states. Each year, SPP studies the entire transmission network through its Integrated Transmission Plan. The R-Project was identified in SPP’s 2012 Integrated Transmission Plan 10-Year Assessment Report as a critical need — and it remains essential today. If NPPD doesn’t build the R-Project, SPP would look for another entity to do so.
What are the next steps for the R-Project?
The next steps include mobilizing construction personnel and equipment to Nebraska. Also, right-of-way agents will begin contacting landowners who have signed easements so crews can start work in those areas. Project construction is expected to take approximately two years.
Is the R-Project transmission line being built to facilitate the development of any specific projects?
No, the line is not being built to meet the needs of any specific projects. The R-Project is being built to improve reliability of the electric grid, relieve congestion on existing transmission lines, and provide opportunities to connect any type of new generation, including renewables.
What is an easement?
An easement is a legal right to use another’s land for specific limited purposes, such as constructing, operating and maintaining transmission lines. NPPD needs easements in order to enter the landowner’s property and perform construction and maintenance activities on electric transmission lines. NPPD will compensate the landowner for the easement area and also pay a structure payment. It’s important to remember that the landowner maintains ownership of the easement area. Although the property owners may continue with their current activities across the easement area, for safety purposes the easement restricts property owners from constructing buildings or structures in the easement area or planting trees or stacking hay under the transmission line. NPPD is responsible for repairing damage incurred during original construction or future maintenance of the R-Project. See the map for more details.
How long is construction expected to take?
The R-Project construction is expected to take approximately two years to complete.
What type of structures will be used and why?
NPPD will use a combination of steel poles, lattice towers and H-frames for the R-Project. The steel poles will typically be used on sections of the project that have relatively good access or are near established roads and cultivated fields.
Lattice towers will be installed on sections of the project that have limited access. Lattice towers minimize impacts to fragile soils due to construction options. For example, the main upper portion of a lattice tower can be erected with a helicopter, which means only a small crane will be needed for the legs, and helical pier foundations can be used instead of concrete foundations.
H-frames will be used near the Thomas County Airport to support height restrictions required by the FAA. The H-frames will have a compact design and provide for shorter spans and overall shorter structure heights in this relatively small area of the project. The H-frames will be comprised of tubular steel and will be placed on helical pier foundations, similar to the lattice towers.
NPPD will use a variety of construction options and equipment to minimize disturbance.
Is NPPD building new roads to deliver material and equipment to construct the line?
No, NPPD does not plan to build new roads. There may be some need to make improvements to the existing roads where needed. Existing roads, trails and paths will be used as much as possible. If NPPD damages an existing road during construction, repairs will be made.
Where will material and fly yards be located?
NPPD will have material storage yards located approximately 50 miles apart along the route. Lattice towers will be constructed on approximately 128 miles of the R-project line and helicopters will be used for portions of tower assembly. Fly yards, which are smaller than material yards, will be located approximately five to seven miles apart along the route with lattice towers.
What is NPPD's approach to restoration?
NPPD has constructed, operated and maintained hundreds of miles of transmission lines in the Sandhills for decades. We understand the Sandhills’ unique and fragile ecosystem, and we take that responsibility seriously. We will continue working closely with landowners, local agencies and restoration experts to ensure the landscape is carefully restored.
What will NPPD do to restore property after line construction?
One of NPPD’s goals for the entire R-Project is to minimize impacts to property. We chose construction methods that are less invasive and are suitable for the terrain.
Where disturbance occurs that needs to be restored, we will seek landowner input on their respective restoration experiences. We have consulted with a variety of agencies who have restoration experts on staff. This process will require NPPD and landowners to work together closely. In addition, NPPD has an individual on staff dedicated to right-of-way restoration.
