The Tehachapi Energy Storage Project (TSP) is a 8MW/32MWh lithium-ion battery-based grid energy storage system at the Monolith Substation of Southern California Edison (SCE) in Tehachapi, California, sufficient to power between 1,600 and 2,400 homes for four hours. At the time of commissioning in 2014, it was the largest lithium-ion battery system operating in North America and one of the largest in the world. TSP is considered to be a modern-day energy storage pioneer with significant accomplishments that have proven the viability of utility-scale energy storage using lithium-ion technology. While originally envisioned as a research and development project, TSP operated as a distribution-level resource for SCE and for calendar year 2020, SCE reported that TSP operated in the wholesale energy market with revenue exceeding operating and maintenance costs. In 2021, SCE began the decommissioning of TSP, which was followed by formal decommissioning by state regulators in 2022. The physical dismantlement of TSP is expected to be completed by the end of 2022.

Mountain Valley Airport (FAA LID: L94) is a privately owned public-use airport located two nautical miles (4 km) southeast of the central business district of Tehachapi, in Kern County, California, United States.The airport is used for glider operations and training. It was established for its close proximity to various advantageous lift effects for soaring where the Sierra Nevada, Tehachapi Mountains and the Mojave Desert meet. The Skylark North Glider School performs glider flight training for civilians as well as for the US Air Force Test Pilot School (from Edwards AFB), the National Test Pilot School (from the Mojave Air & Space Port), NASA and others. Due to the ongoing training contract with the US Air Force Test Pilot School, most NASA Space Shuttle pilots who came from the Air Force have probably received glider training at Mountain Valley Airport.

There are no interior hallways at Tehachapi High. The design originated with a Central Valley school without the Tehachapi Valley's wind. When the school first opened, students were injured by the wind slamming doors open and shut, requiring changes to the doors' construction.The gym and cafeteria underwent major transformations to give it a cafe-like feel with bar stools, booths, and individual seating to accommodate nearly 1,700 students using funds that could not be used to pay staff or for educational purposes. Over a summer, the Associated Student Body team got together to effect the changes.

Tehachapi Pass (Kawaiisu: Tihachipia, meaning "hard climb") is a mountain pass crossing the Tehachapi Mountains in Kern County, California. Traditionally, the pass marks the northeast end of the Tehachapis and the south end of the Sierra Nevada range. The route is a principal connector between the San Joaquin Valley and the Mojave Desert. The Native American Kitanemuk people used the pass as a trade route before the American settlement of the region in the 19th century. The main line of the former Southern Pacific Railroad opened though the pass in 1876; the tracks are now owned by the Union Pacific Railroad and shared with BNSF Railway as the Mojave Subdivision. U.S. Route 466 was built in the 1930s, and the road is now State Route 58. The Pass is also the route of the planned California High-Speed Rail line. The Tehachapi Mountains are also crossed by Tejon Pass at the southwest end of the range.

The Errea House, a historic house located at 311 S. Green St. in Tehachapi, California, is the house is the only surviving building from the settlement of Tehichipa, the first town in the Tehachapi area. Tehichipa was founded in 1869, and the house was built sometime between 1870 and 1875. In 1876, the Southern Pacific Railroad bypassed Tehichipa, instead establishing a new townsite at Tehachapi Summit, which later became Tehachapi. The railroad's action led to the decline of Tehichipa's shipping industry, and the town's residents gradually moved to Tehachapi. The Errea House was moved to Tehachapi as well around 1900. No buildings from the original settlement survive at the site of Tehichipa, and the Errea House is the only building remaining from the town. The Errea House is now located across from the Tehachapi Museum, where it helps illustrate the city's early history.The Errea House was added to the National Register of Historic Places on July 29, 1997.
