The Tehachapi Renewable Transmission Project (TRTP) is a series of new and upgraded high-voltage electric transmission lines and substations capable of carrying 4,500 megawatts of electricity (enough energy to supply three million homes) from renewable and other generators in Kern County south to San Bernardino County. The Project is designed to provide added capacity to strengthen SCE’s electrical system and also deliver clean, renewable energy to the region to help meet California’s renewable energy goals. SCE has completed construction of the 173 mile TRTP electric transmission line and energized the line fourth quarter of 2016. Throughout TRTP’s construction, SCE worked closely with local officials, property owners, residents, businesses and others in efforts to provide helpful project updates, minimize potential impacts and respond quickly to requests for information. We recognize that this has been a long process and thank you for your patience, support and willingness to work with SCE during the past several years. We look forward to being a good neighbor for many years to come.
When our infrastructure projects affect surrounding communities, there may be questions. We are committed to keeping you informed and up to date. Common questions include:
- Why our proposal uses overhead electric transmission lines instead of underground
- Why underground lines are so much costlier
- How infrastructure decisions are made by regulators
