Why we built Temecula Strong

SDG&E's Golden Pacific Powerlink is a proposed 500-kilovolt transmission line running from Imperial Valley to a new substation north of the San Onofre Nuclear Generating Station (SONGS). Along the way, it would cut through more than five miles of Temecula Creek — roughly 21 steel lattice towers, some as tall as a 20-story building.

SDG&E serves San Diego and Orange counties. It does not serve Riverside County. Yet Temecula is the community asked to live beneath these towers, for power routed elsewhere.

What this site is for

This is a fact-based community resource. Our goals:

• Lay out the facts — the route, the towers, the regulatory process, and the claimed impacts, with sources.
• Track the timeline — the project was approved by CAISO back in 2023, but Temecula wasn't notified until April 2026.
• Help you act — the CPUC holds the decision, and public comment becomes part of the official record.

Local government can't veto this project. But the record can shape the CPUC's decision — and that record is built from comments like yours.

Where things stand

SDG&E's application to the California Public Utilities Commission is expected in Fall/Winter 2026, opening the formal proceeding. That filing should also include the project's official cost figure, which we're still waiting on.
