The Southern California Public Power Authority (SCPPA) on July 14 filed with the Public Utilities Commission of Nevada a notice of an application with the U.S. Bureau of Land Management (BLM) for approval to build a 500-kV transmission line and associated facilities to be located in Clark County, Nev.
The Apex Transmission Line includes the development, construction, operation, and maintenance of the approximately 10-mile to 14-mile line located primarily on federal land administered by the BLM, and possibly on a small portion of privately owned land, depending on final design and approval. The final length of the line would depend on final design and approval, SCPPA added.
The line is proposed to be located within the Dry Lake Valley basin in northeast Clark County, about 15 miles northeast of Las Vegas, and would connect the Apex generating station (Apex) and the Crystal switching station (Crystal), SCPPA said. The line would generally be located to the west of I-15 and would run from Apex, generally to the northeast, crossing Highway 93 near the southern edge of the Arrow Canyon Range, and would continue to the northeast through the Dry Lake Valley, connecting at Crystal, SCPPA said.
The Apex Project consists of the single-circuit, overhead line, including related access roads and about 45 lattice tower structures that would range in height from 60 feet to 200 feet, SCPPA said.
SCPPA said that it will submit its Utility Environmental Protection Act (UEPA) application at the conclusion of the federal environmental review process, and at that time, it will apply for, and request that the commission issue, a UEPA permit to build the Apex Transmission Line.
According to an “Application for Energy Projects ‘Fund for the Recovery of Costs,’” filed with the Nevada Department of Wildlife and included in the July 14 filing made with the commission, the Los Angeles Department of Water and Power (LADWP) plans to build the line with a 900-MW capacity. Construction is scheduled to begin in August 2020, and would be finished within 15 months, the application added, noting that testing and commissioning is scheduled to begin in October 2021, and would be finished within six months. The transmission line would be in commission by April 2022, the application stated.
According to SCPPA’s website, SCPPA is a joint powers agency comprised of one irrigation district and 11 municipal utilities, including the LADWP.
