Diseased or overgrown trees can damage power lines and lead to outages. To ensure reliable service, we have extensive tree pruning and removal programs in place, but you may also be responsible for the upkeep of any vegetation near power lines on your property. Learn to identify the two types of power lines we use and be sure to follow our guidelines for planting and maintaining vegetation accordingly.

Distribution Lines

Power Transmission Lines

Transmission lines are large wooden or steel poles that transfer high-voltage power, and often run across the landscape or behind homes. Because these lines carry such high voltages, National Grid has established rights of way (ROWs) where vegetation growth around transmission lines is strictly regulated to prevent damage. If you have transmission lines on your property, you can find more about our operational programs and your responsibilities below:
