Your power comes from a wide variety of generating facilities from all over the Midwest. NPPD uses a diverse mix of generation resources including coal, natural gas, wind, water, and nuclear power.
The power system is an interconnected grid that distributes power as needed from a wide variety of sources. From the power plant, electric energy is delivered through a series of lines and substations where the voltage is reduced to the proper level for end-use customers.
The R-Project consists of routing and siting a new electrical transmission line from NPPD’s Gerald Gentleman Station near Sutherland north to the Cherry County area, and then east to either Holt, Antelope or Wheeler County.
There are three main reasons behind the R-Project. First, adding this line will enhance system reliability throughout Nebraska. Secondly, the line will help reduce congestion on existing power lines to allow for better system operation. This operational efficiency is a benefit to all Nebraskans. Finally, the new transmission line creates an opportunity for connection of renewable energy resources to the electric grid.
This slide shows what parts of Nebraska were heavily impacted by storms in the past. Although storms can occur anywhere in Nebraska, this new 345-kV transmission line generally avoids those areas that have historically experienced significant electric system damage. This results in providing another layer of service reliability to our bulk transmission system throughout the entire state.
NPPD is a member of the Southwest Power Pool (SPP), a regional transmission organization. The SPP conducted a three-year study, also known as the Integrated Transmission Plan, to assess the needs of the entire transmission network within the SPP region over the next 10 years. The study identified the need for two, 345 kilovolt (kV) transmission lines in Nebraska, with one segment to run from NPPD's Hoskins substation located southwest of Hoskins to a new substation in the Neligh area. The other line segment, known as the R-Project, will run from NPPD's Gerald Gentleman Station north to the Cherry County area and then east to a new substation located in either Holt, Antelope or Wheeler County.
NPPD is holding a variety of meetings to engage various stakeholders (property owners/tenants, elected officials, wholesale customers, agencies and interest groups, community/area and business leaders, and media).
The public involvement process includes:
-- Public Outreach Meetings
-- Public Open Houses (Study Area, Corridors, Alternatives)
-- Online Public Meeting
-- A Formal Public Hearing
At each phase of the Project, public input is used to help determine the opportunities and constraints throughout the routing process. Currently we are in phase 2 of the routing process and NPPD is sharing the transmission line corridors and substation siting areas.
NPPD needs your input to help continue determining the opportunities and constraints in the transmission line corridors and substation siting areas. Click on the comment form button to provide your input.
The next three posters show examples of routing criteria NPPD has used in the past when siting a new transmission line. If you have any other examples, please share them with us through the comment form.
Throughout the routing process, NPPD coordinates with federal, state, and local agencies to help determine what environmental resources might be impacted by the Project. These resources include, but are not limited to: agricultural lands, sensitive, threatened and endangered species, cultural and historical resources, and water resources.
NPPD strives to build positive, long-term relationships with landowners and tenants. The goal is to navigate through the process of Right-of-Way permitting, easement acquisition, and post-construction so that these relationships can remain positive for years to come. This is why it is important to know how this Project affects you.
In the Engineering section we will explain the following; the type of structures that will be used on the project, typical structure locations and a description of the construction process.
In agricultural land, the line will generally be located along either section or half section lines. The 345kV structures are designed to span an average of ¼ mile, this allows the structures to be placed in the corners of center pivot irrigation systems and not interfere with their operation.
This poster describes the typical steps necessary to construct the transmission line;
After the survey of the right of way is completed, the first construction step would be to install gates and culverts to make it easier for the construction crews to access the right of way.
The next task would include clearing the right of way of trees and other structures that might interfere with the safe operation of the line.
After the tree clearing is complete, crews would next auger the holes and pour the concrete foundations.
After sufficient time for the concrete to cure, the crews would haul the pole sections to the site and assemble them, following the assembly; a large crane would be used to set the structure on the foundation.
After a significant number of the structures have been set, the crews will begin the wire stringing operation. This operation requires several steps to complete the installation on of the wire. Because the wire comes in reels with approximately 2 miles per reel, the crews will need to have a wire stringing set-up approximately every two miles.
The final step would be to clean-up and restore the right-of way to as close as possible to its original state.
This poster shows how the various structure types being considered for this project look from a distance.
During our first round of open houses, we asked attendees what was most important to them regarding this project. As you can see, the most important issue was proximity to residences, followed by minimizing impact to ranch and farm operations and restoration of disturbed areas.
