EMF and Noise Studies

Tri-State has taken steps to model the generation of audible noise and within the design plan of its transmission facilities to implement certain methods to reduce the noise during operation.

Additionally, Tri-State has modeled electric fields (calculated as kilovolts per meter) and magnetic fields (calculated as milli Gauss) that the proposed transmission line would produce. A computer program is used to accurately predict these fields within transmission corridors.

The report shows the typical EMF levels for the proposed transmission line. At a distance of 300 feet, at times of average electricity demand, the magnetic field from the lines can be similar to typical levels in most homes.

What is EMF?

Electric and magnetic fields (EMFs) are invisible lines of force associated with the production, transmission, and use of electric power such as those associated with high-voltage transmission lines, secondary power lines, home wiring, appliances and lighting.

Many studies of EMF have been conducted but none have identified a mechanism where EMF can cause disease. Visit the following Web sites to investigate the topic further:


Project Benefits

The proposed project would:

  • Improve the power delivery infrastructure to Colorado and New Mexico's San Juan Basin
  • Increase the load serving capabilities for residential, small business, and industrial electric consumers (including oil and gas developers)
  • Relieve transmission constraints for the region
  • Provide a pathway for potential renewable energy development
