A power delivery project, many years in the making, has started transmitting energy through Bourbon County.
NextEra Energy Transmission (NEET) – Southwest began producing energy over the 92-mile, 345-kV Wolf Creek – Blackberry transmission line on July 16, 2025, according to Lillie Zeng, spokesperson for NEET-Southwest.
The project was within budget and nearly five months ahead of Southwest Power Pool’s (SSP) required in-service date. The project was completed within three years, according to the spokesperson.
This is the second of three competitively awarded transmission projects in SPP that the company is building, she said.
“NextEra Energy Transmission – Southwest is proud to support SPP and its customers in Kansas and Missouri with a transmission line that will help enhance grid reliability and support economic growth in the region.”
The NEET-Southwest field office is at 2522 Richards Road, Fort Scott, KS 66701.
“We are in the process of hiring local office staff. In addition, NEET Southwest has access to approximately 70 affiliate technical staff located in the project area,” according to the spokesperson.
The project included a diagonal power line through the southwest part of Bourbon County as noted in the graphic from NextEra.
The process can be summed up this way:
Electric power is generated by nuclear energy at the Wolf Creek Nuclear Plant near Burlington, Kansas in Coffee County.
The power is moved via transmission power lines to the southwest, to the Blackberry Electrical Substation, just over the state line in Missouri.
There, high voltage power is then stepped down to a lower voltage and distributed over power lines to neighborhoods, businesses, and residences, according to https://www.nexteraenergytransmission.com/subsidiaries/neetsw/projects/wolf-creek-blackberry
This project is a new 94-mile, 345-kilovolt (kV) regulated transmission line that runs from the Wolf Creek substation (Evergy Energy) in Kansas to the Blackberry substation, Associated Electric Cooperative Inc.(AECI) in Missouri.
About Wolf Creek
Wolf Creek Nuclear Generating Station, Kansas’s only nuclear power plant, has been providing energy to Kansans and Missourians since 1985, according to https://www.evergy.com/landing/wolf-creek-nuclear-generating-station
The Wolf Creek site is about 10,500 acres, and 1,500 acres of company land are reserved and managed for wildlife. Wolf Creek employs approximately 750 employees, many of whom have worked at the site since the plant began providing electricity to the nation’s power grid more than three decades ago, according to the Evergy website.
Wolf Creek provides electric generation for Evergy and generates about 1,200 megawatts of electricity, which is enough energy to power more than 800,000 homes, according to the Evergy website.
Wolf Creek generates 20.7 percent of Kansas’ electricity, and 36 percent of its emissions-free electricity, according to the NextEra website.
Evergy is an electric service provider in Bourbon County.
“Evergy and Next Era are both members of the Southwest Power Pool (SPP), which helps manage the power grid and energy markets across 14 states in the middle of the country, including Kansas and Missouri,” said Evergy Director of Corporate Communications Gina Penzig. “SPP keeps track of how electricity moves through the system and helps ensure coordination among area utilities.”
“The Wolf Creek–Blackberry Transmission line simply connects to Evergy’s equipment and helps send electricity into the power grid,” Penzig said. “The SPP chose Next Era to build this line through a competitive bid process. Even though the line connects to Evergy’s substation and electricity flows through it, Next Era owns and operates the line.”
The project is part of the 2019 Integrated Transmission Plan approved by SPP in October 2019 to address the need for a more reliable and cost-effective grid. This project will reduce congestion and provide market efficiencies and benefits to ratepayers, according to the NextEra website.
According to NextEra, the project benefits are:
- “Leads to lower electricity costs for customers
- Enhances the reliability and resiliency of the electric grid
- Creates job opportunities in the short and long term
- Spurs investment in the local economy during construction
- Supports public health and safety through access to reliable electricity
“Environmental & Visual Considerations
-
Conducted rigorous environmental analyses to limit impacts on wildlife, sensitive habitats, and natural resources
-
Coordinated with federal and state agencies to identify protected species found along the route
-
Selected monopole structures to minimize tree clearing and agricultural impacts
-
Incorporated considerations for visual impacts into the routing study.”
