Controversial $2.3B power line threatens California's Anza-Borrego Desert Park

A utility giant's push for renewable energy clashes with conservationists over a desert park's future. Will California sacrifice 650,000 acres for progress? The project's 200-foot towers and blinking lights could reshape one of America's largest state parks—forever.

Controversial $2.3B power line threatens California's Anza-Borrego Desert Park

A proposed high-voltage power line in San Diego County has triggered strong opposition due to its planned route through Anza-Borrego Desert State Park. The $2.3-billion Golden Pacific Powerlink would stretch 140 miles, using steel towers to connect a major urban area to a renewable energy zone. Critics warn the project could harm wildlife, disrupt habitats, and alter the park’s natural landscape.

San Diego Gas & Electric (SDG&E) is pushing ahead with the project, which would require a 200-foot right-of-way for its towers. Some of these structures may need blinking safety lights at the top. The utility argues that the chosen path is the best option because it follows an existing 69-kilovolt line. However, opponents claim the two lines are not comparable in scale or impact.

The powerlink would cut through nearly 650,000 acres of protected desert, home to endangered species like the Peninsular bighorn sheep. Environmental groups warn it could disrupt migration patterns and affect over 1,500 plant and animal species. Beyond wildlife concerns, the project may also impact recreation, tourism, and cultural sites, including Tamarisk Grove Campground and Angelina Spring Cultural Preserve. Before filing a formal application by the end of the year, SDG&E is collecting public feedback. The project will still need to pass state and federal environmental reviews. Utilities like SDG&E profit from such infrastructure projects, earning regulated returns on their investments.

The Golden Pacific Powerlink remains one of California’s largest and most expensive transmission projects. If approved, it would link a major population centre to renewable energy sources. The final decision will depend on environmental assessments and ongoing public debate.
