A map of the Wolf Creek-Blackberry transmission line route reaching from Kansas to Missouri.

Project Overview

In October 2021, NEET Southwest was awarded the construction of a new approximately 92-mile 345 kV transmission line from the Wolf Creek substation in Coffey County, Kansas to the Blackberry substation in Jasper County, Missouri. NEET Southwest finances, develops, constructs, owns, operates and maintains the Wolf Creek-Blackberry 345 kV transmission project. The project received regulatory approvals and construction is anticipated to begin soon. NEET Southwest anticipates that the line will be in service by early 2025.

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.
