Where these facts come from

This site aims to be fact-based. Below are the sources behind our claims — official project and government materials, press coverage, regulatory references, and community analyses (the last clearly labeled, since some figures are still being verified).

News & Media

  • Los Angeles Times — coverage of the proposed route

    Los Angeles Times · May 17, 2026

    Visit

    Reports the CPUC's 2008 rejection of the Sunrise Powerlink route through Anza-Borrego as 'environmentally unacceptable and infeasible' (50+ significant impacts), and the co-location debate over the 1930s 69 kV wooden-pole line versus 200-ft steel lattice towers.

Regulatory & Reference

  • California Public Utilities Commission (CPUC)

    State of California

    Visit

    Regulates investor-owned utilities and approves certifications/permits for high-voltage transmission lines above 50 kV. Five commissioners appointed by the Governor; holds primary approval authority over the project.

  • Power line easement setbacks for schools

    CDE guidance on overhead transmission line easement setbacks: 100 ft (50–133 kV), 150 ft (220–230 kV), and 350 ft (500–550 kV) — the basis for the Vail Ranch Middle School setback analysis.

  • California Independent System Operator (CAISO)

    State of California

    Visit

    Manages California's grid and, through its annual Transmission Plan, identified and approved the line in Spring 2023 — the planning step that preceded any Temecula notification.

Community & Advocacy

  • 500 kV erection process & impacts on Temecula Creek

    Community technical analysis

    Primary doc

    Resident-produced analysis estimating construction footprint: ~84 footings (5 ft × 50 ft), concrete and access-road truck counts, and drilling-rig specifications along 5+ miles of creek. Community-sourced; figures pending verification.

  • Vail Ranch Middle School — 350 ft setback map

  • 'Save Temecula / Fight the Powerlink' advocacy flyers

    Community advocacy materials

    Primary doc

    Campaign flyers and infographics covering property-value, wildfire, health/EMF, and quality-of-life concerns, plus the magnetic-field-vs-distance reference. Community-sourced; specific figures are flagged for independent verification before publication.

Figures drawn from community advocacy materials are labeled as such and are being independently verified against primary sources before they're presented as established fact.
