Tehachapi Renewable Transmission Project
project involving the construction of approximately 173 miles high-voltage transmission lines
The Tehachapi Renewable Transmission Project is a project involving the construction of approximately 173 miles (278 km) of new and upgraded high-voltage transmission lines for transmission of electricity from wind farms and other generating units in southeastern Kern County, California to Los Angeles County and San Bernardino County.
The project, developed and operated by Southern California Edison, commenced construction on March 7, 2008 and was completed and placed in operation in December 2016. With a capacity of 4,500 megawatts, the transmission system can provide power for an estimated 3 million homes.
It passes through sections of the Tehachapi Mountains, Sierra Pelona Mountains, and Antelope Valley.
State laws requiring SCE to provide at least 33% of its power service from renewable sources by 2020 is driving the project. SCE had no interest in owning the land that the project is on, but needed to construct the transmission system nonetheless to meet the renewable source laws.
This brief starts where responsible research should: with the source description of “Tehachapi Renewable Transmission Project” as project involving the construction of approximately 173 miles high-voltage transmission lines. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as project involving the construction of approximately 173 miles high-voltage transmission lines. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 11, 2025. The linked authority identifier is Q3407278. The first chronological checks are 2008, 2016 and 2020.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
