Kenedy Switch–Nixon–Seguin Transmission Line Upgrade

Project Name:​​Kenedy Switch–Nixon–Seguin Transmission Line Upgrade

Project Location:
​The project is in Guadalupe, Gonzales and Karnes counties. It goes from the Kenedy Switch substation in Kenedy to the new Deer Creek Substation that LCRA Transmission Services Corporation (TSC) will construct between the Capote and Nash Creek substations. Guadalupe Valley Electric Cooperative (GVEC) owns the Capote and Nash Creek substations; AEP owns the Kenedy Switch Substation; and LCRA TSC will build and own the Deer Creek Substation.

Project Description:
​LCRA TSC will upgrade the 71.1 miles of existing 69-kilovolt (kV) transmission lines to 138-kV by replacing the conductor and structures between the Kenedy Switch, Nixon and Seguin substations. LCRA TSC will add the new Deer Creek Substation where GVEC’s Seguin-Gonzales transmission lines intersect LCRA TSC’s Nixon-Luling transmission lines. LCRA TSC also will add an autotransformer at the new Deer Creek Substation and make upgrades to the Helena, Magnolia Tap, Milton and two Nixon substations. (LCRA TSC and AEP each own a substation in Nixon.)

Project Need:
​Load growth in Karnes and Gonzales counties and surrounding communities, mostly due to the development of the Eagle Ford Shale formation in South Texas, has created the need for transmission improvements.
Project Budget:
​$37.507 million
