The Haynes Repowering Project modernized how residents of Los Angeles receive their electricity. By updating the technology at the Haynes Generating Station, the plant became more reliable and cleaner.

This project consisted of the construction of new 500kV and 230kV electric transmission lines between the existing Imperial Valley and Sycamore Canyon Substations, as well as the construction of a new Suncrest Substation. Additional system upgrades and modifications were also necessary in order to reliably operate the new lines. The entire project spans 117 miles between the El Centro area of Imperial County and southwest San Diego County.
