Analysis of the entire US Transmission Network

The largest machine on the planet is the U.S. power grid, with nearly 7 million miles of transmission and distribution lines. For the first time, the entire publicly accessible transmission grid of the United States of America has been analyzed as a whole. All 573,323 miles of overhead transmission lines were surveyed by LiveEO to determine the length of transmission lines threatened by vegetation.

The main cause of outages, Vegetation

Reports of power outages caused by storms, hurricanes, wildfires, or minor events such as fallen trees coming into contact with power lines frequently hit the news. In fact, more than 50% of outages are the result of vegetation affecting power lines. Condition-based satellite monitoring reduces the number of incidents.

Half of all Transmission Lines are near Vegetation

Over 1.7 million square kilometres of imagery was processed to examine even the most remote transmission lines. This represents about 45% of the total land area of the United States. The resulting analysis concludes that, overall, 50% of the transmission grid in the United States is located near vegetation closer than 90 feet.

166,000 miles with vegetation closer than 30 feet
244,000 miles with vegetation closer than 60 feet
291,000 miles with vegetation closer than 90 feet

The Preparation of the Analysis

To assess the number of miles of transmission lines exposed to vegetation, LiveEO analyzed the entire publicly available U.S. transmission network. Using an AI-powered approach, LiveEO demonstrated the feasibility of analyzing infrastructure the size of a continent. A task that was considered nearly impossible without the use of satellite data.


The basis of the analysis is georeferenced transmission network data.

Satellite Data

In order to produce a precise analysis, accurate satellite images are acquired according to the grid.


Every pixel within a certain distance around the grid is classified as tree or non-tree.

Risk Assessment

Segments of the grid that are within the critical distance of any tree cover are identified.


Summary statistics are generated for all vegetation exposed grid segments.

Miles Investigated

Miles studied ​to determine the total amount of transmission lines threatened by vegetation. The entire U.S. electric transmission system.

Square Miles Analysed

Square miles surveyed to determine the amount of vegetation in the vicinity and its distance from transmission lines.

Square Miles Processed

Such large-scale analysis is only possible through the use of satellite data, which allows networks the size of a continent to be monitored at once. LiveEO provides this vegetation monitoring and other analysis for electric utilities, pipeline and rail operators at varying levels of accuracy and frequency.
