LCRA seeks amendment to CCN for 138-kV transmission line in Texas

Lower Colorado River Authority (LCRA) Transmission Services on Sept. 7 filed an amendment to a certificate of convenience and necessity (CCN) for its E.C. Mornhinweg to Parkway transmission line project.

The company requested that the Public Utility Commission of Texas (PUCT) amend the certificate for a proposed construction of a new 138-kV transmission line in Comal and Guadalupe counties, Texas (PUCT Docket No. 40684).

The new circuit will connect the existing Guadalupe Valley Electric Cooperative-owned Parkway substation in Guadalupe County to a new New Braunfels Utilities substation in Comal County.

According to the project’s website, the line “will provide a power source to the E.C. Mornhinweg substation, provide a power source along the IH-35 corridor between New Braunfels and San Antonio that can serve future load, and provide a power transmission path between Central Texas and the San Antonio area.”

The entire project will be about 8 to 11 miles in length, depending on the final route selected. LCRA will install new equipment at both the Comal County substation and the existing Parkway substation.

“In addition, if route 10 or a similar route using Alternate Route Segments L1, NI, 01, and Cl, a direct path across IH-35 from the ECM substation to the existing LCRA transmission right-of-way (ROW), is selected by the PUC, LCRA requests that the portion between the ECM substation and the existing ROW be approved and certificated by the PUC for a second 138-kV circuit to be added as needed in the future,” LCRA said.

The total estimated cost for the project ranges from about $12m to $30m depending on the route chosen. The proposed project is presented with 14 alternate routes. The commission may approve any of the routes or route segments.

The deadline for intervention in the proceeding is Oct. 22, according to the commission.

The company on Sept. 7 also mailed notice letters to potentially affected landowners located along the route options, according to the project website.
