Power lines near me: transmission line map by address
Enter a US street address to see the high-voltage transmission lines near it: every line of 100 kV or more within 1 mile, with the distance in feet, direction, voltage, owner and the substations it connects, and counts within 500 feet, a quarter mile and half a mile. The answer is read from federal transmission line maps when you search. Local distribution lines on street poles are not included.
What is on the transmission line map
The map covers high-voltage transmission lines of 100 kV and above across the United States, from 115 kV and 138 kV regional lines up to 345 kV, 500 kV and 765 kV bulk-power lines and a few direct-current lines. Each line carries its owner as recorded, voltage, status and the substations at its ends. A long line can appear as several segments, and most lines are overhead.
What the map does not show
Distribution lines, the lower-voltage wires on poles along most streets, are not in the data, and neither are most lines under 100 kV. Lines built or rerouted recently may be missing. Distances run from the address point to the mapped line, which is a regional map position, not a survey of the right-of-way. Utility easements are recorded in the county land records, not in this map.
Living near power lines: what the distance means
The magnetic field from a power line falls off quickly with distance. The National Institute of Environmental Health Sciences gives the World Health Organization's 2010 figures for a 230 kilovolt transmission line: 57.5 milligauss immediately beside the line, 7.1 milligauss at 100 feet and 1.8 milligauss at 200 feet.
On health, NIEHS says that during the 1990s most research on extremely low frequency fields looked at sources such as power lines, substations and appliances; some of those studies showed a possible link between field strength and childhood leukemia, but the association was weak, and the few studies of adults show no evidence of a link with adult cancers. The lookup reports distances and voltages only.
Questions
How do I find power lines near my house?
Enter the address in the lookup on this page. It locates the address and lists every high-voltage transmission line (100 kV and above) on federal maps within 1 mile, nearest first, with its distance in feet, direction, voltage, owner as recorded and the two substations it connects. The wires on street poles in front of most houses are distribution lines and are not in this data.
Where is the 765 kV transmission line map?
765 kV is the highest alternating-current voltage class in the US transmission network, and very few lines are that large. Enter an address to see whether a 765 kV line, or any other line of 100 kV or more, is within a mile.
Does the magnetic field from a power line drop with distance?
Yes, quickly. The National Institute of Environmental Health Sciences cites the World Health Organization (2010): a magnetic field of 57.5 milligauss immediately beside a 230 kilovolt transmission line measures 7.1 milligauss at 100 feet and 1.8 milligauss at 200 feet. The lookup gives the distance in feet from the address point to each mapped line.
Is it safe to live near power lines?
The National Institute of Environmental Health Sciences says that in the 1990s some studies of extremely low frequency fields from power lines showed a possible link between field strength and childhood leukemia, but that the association was weak, and that the few studies of adults show no evidence of a link with adult cancers such as leukemia, brain cancer and breast cancer. HeritageDeed gives the distance and voltage, not health advice.
Who owns the transmission line near me?
The result shows the owner recorded for each line. The field is sometimes empty ("not available") or names a different utility from the one that operates the line today, so check with the utility that serves the area before relying on it.
How current is the power line map?
The federal transmission line map is updated on the government's schedule, not ours. Lines built, rerouted or removed recently may be missing or still shown.
The Environmental Records Report includes these transmission lines with mapped faults, the flood zone, radon, wetlands and the federal contamination lists for the address, for $29. For ownership, deeds, mortgages and liens, a title report is $49 per report in the counties we cover.
