BPA operates thousands of miles of high-voltage power lines across the Pacific Northwest, creating widespread 60 Hz magnetic field exposure.

Plain English Summary

Summary written for general audiences

This government report from the Bonneville Power Administration (BPA) outlines the organization's mission and operations in the Pacific Northwest power transmission system. BPA manages high-voltage power lines that carry electricity across Washington, Oregon, Idaho, and parts of surrounding states. The document explains BPA's role as a federal agency overseeing one of the nation's largest electrical transmission networks.

Why This Matters

The Bonneville Power Administration operates thousands of miles of high-voltage transmission lines throughout the Pacific Northwest, creating one of the most extensive EMF exposure networks in the United States. These power lines typically operate at voltages from 115,000 to 500,000 volts, generating magnetic fields that can extend hundreds of feet from the lines themselves. What this means for you is that millions of people in the region live, work, or travel regularly within the magnetic field zones of BPA's transmission infrastructure.

The reality is that BPA's transmission system represents a massive source of 60 Hz magnetic field exposure across four states. While the agency focuses on reliable power delivery, the health implications of this extensive EMF infrastructure deserve equal attention. The science demonstrates that proximity to high-voltage transmission lines correlates with increased risks for childhood leukemia and other health effects, yet regulatory agencies continue to prioritize electrical reliability over public health considerations.

Quick Questions About This Study

BPA is a federal agency that operates the Pacific Northwest's high-voltage electrical transmission system, managing power lines that carry electricity across Washington, Oregon, Idaho, and parts of surrounding states for utilities and consumers.
BPA operates one of the nation's largest transmission systems, with thousands of miles of high-voltage power lines ranging from 115,000 to 500,000 volts spanning across four states in the Pacific Northwest region.
Yes, BPA's high-voltage transmission lines generate 60 Hz magnetic fields that can extend hundreds of feet from the power lines, potentially exposing millions of Pacific Northwest residents to elevated EMF levels.
BPA transmission lines typically operate at voltages ranging from 115,000 volts (115 kV) up to 500,000 volts (500 kV), with higher voltages generally producing stronger magnetic fields in surrounding areas.
BPA's transmission network primarily covers four states in the Pacific Northwest: Washington, Oregon, Idaho, and portions of surrounding states including Montana, California, Nevada, Utah, and Wyoming.
