Public Utility Commission (PUC) of Texas staff on May 9 proposed a procedural schedule for Oncor Electric Delivery Company’s proposed Littman-Phillips Andrews Tap 138-kV Transmission Line Project.
As TransmissionHub reported, Oncor on April 10 filed with the PUC an application for a certificate of convenience and necessity (CCN) regarding its proposed project.
The company said that the approximately 11.1-mile, double-circuit capable line, with one circuit in place initially, would connect the existing Oncor Littman substation, located in northwest Andrews County near the southwest intersection of State Highway (SH) 176 and the Texas-New Mexico state line, to the proposed Phillips Andrews Tap, to be located about 2.75 miles northeast from the intersection of Nelson Road and SH 176 in Andrews County.
The estimated total cost of the transmission facilities is about $9.7m, while the estimated total cost of the substation facilities is $452,000, Oncor said, noting that the station facility costs account for the necessary equipment to modify the existing substation to accommodate the proposed line.
Discussing the need for the proposed project, Oncor said that ERCOT stakeholders reviewed the proposed line and associated station work through the ERCOT Regional Planning Group Project Review Process as part of Oncor’s proposed Littman-Fullerton 138-kV Line project, of which the proposed project is a sub-section.
Oncor also said that the proposed project supports continued load growth on the existing 138-kV substations in Andrews County, provides transmission facilities in an area without transmission facilities to serve new substations, and improves reliability by providing an alternative transmission feed to radially fed substations.
The proposed project also provides operational flexibility in response to transmission line outages, obtaining clearances for maintenance of equipment or upgrading of facilities, and connecting new load to the system.
Oncor added that it continues to experience load growth in West Texas due to oil and natural gas production, mid-stream processing, and associated economic expansion in the area referred to as the Permian Basin.
According to staff’s May 9 filing, the proposed procedural schedule calls for the intervention deadline to be May 25, followed by the deadline for intervenors to request a hearing on the merits (as well as the deadline for intervenor comments if no hearing is requested) to be June 1.
“If qualified for informal disposition,” the proposed procedural schedule calls for the deadline for staff to request a hearing on the merits (as well as the deadline for staff’s recommendation on final disposition if no hearing on the merits requested) to be June 12.
The schedule calls for the deadline for the applicant to request a hearing or respond to intervenor comments and the staff recommendation on final disposition – or the deadline for parties to file a proposed notice of approval – to be June 19.
The schedule further notes that “if applicable, administrative review completed” on June 29.
