Minco-Pleasant Valley-Draper 345 kV Transmission Line Project


On April 26, 2022, NEET Southwest was awarded a project by the Southwest Power Pool to construct a new approximately 48 miles of 345 kV transmission facilities in Oklahoma, interconnecting the Minco substation in Grady County and the Pleasant Valley and Draper substations in Cleveland County.

The project is needed to reduce congestion on existing lines and enable the additional flow of low-cost generation from the west to the fast-growing load centers of Norman, Moore and Oklahoma City in the east and is expected to be in service in Q1 2024.

The Project route goes through Grady, McClain and Cleveland County in Oklahoma and considers the least amount of landowner, environmental and cultural impact.
