Let’s Keep Trees Away from Power Lines
Trees, shrubs, and other vegetation can cause safety hazards and power outages if they grow into or near power lines. To support safety, we regularly trim or remove trees that are dead, dying, diseased, or growing near or under power lines.
SCE offers a free “make-safe” program. As part of this program, SCE will assess and remove portions of trees to a level that would allow other workers to remove or prune the rest of the tree safely. This includes treating stumps after removing a tree after customer approval has been obtained.

What is Vegetation Management?
Vegetation management is a broad term that describes work we do to minimize the impact trees and vegetation have on providing safe and reliable electric service. It includes hazard tree assessments, tree pruning and removal, brush removal, and weed abatement.
It is a matter of public safety and the reliability of the power grid. State regulations require utilities to trim trees or vegetation which could cause a power outage and spark a fire or be a danger to the public. Enhanced tree trimming is part of the SCE Wildfire Mitigation Plan.

SCE Trims Trees to Keep You Safe
DID YOU KNOW? Every year, SCE inspects 1.6 million trees throughout its 50,000-square-mile area that might pose a hazard to power lines, more than 740,000 of which are in high-fire-risk areas.

SCE trims trees near power lines as a free service to customers to keep the public safe. During trimming, trees will be trimmed to create a minimum 12-foot clearance from a power line.
Please Note: SCE’s responsibility is to protect public safety and the reliability of electric facilities. Therefore, pruning only occurs on the sides of the tree that could encroach on power lines. SCE prunes the tree in accordance with national standards designed to protect tree health. The pruning focuses on power line clearance and does not necessarily encompass the entire tree or consider the resulting aesthetics.

- Electrical Emergency, Call 911
How Will I Know If My Tree Is Being Trimmed?
SCE conducts annual inspections of trees and vegetation near lines. If a tree is identified for “light pruning,” the customer will be notified via door hanger 30-45 days before maintenance. A second door hanger is provided within 24-48 hours before scheduled maintenance. The door hanger has a phone number the customer can call for more information. Customers with trees that require “heavy pruning” will be contacted in person by SCE to discuss a pruning plan.
A door hanger will be posted 30-45 days before trimming.
A second door hanger will be posted 24-48 hours before trimming.
Customers will be contacted in person if heavy pruning or tree removal is required.
Who Can I Call If I Have Questions?
The door hanger will list a contact number to call to discuss the tree-trimming plan for your property.

SCE confers with the property owner to explain the tree removal process and obtain customer permission before removing a tree. Under imminent situations, SCE reserves the right to proceed without permission.
An SCE tree trimming crew will cut down the tree at no charge to the customer. The crew will dispose of the tree or, if the property owner chooses, cut it into firewood.

While trees and vegetation provide many benefits, they can also present major obstacles in meeting Southern California Edison’s responsibility to deliver electricity to customers as safely as possible. If you’re planting a new tree or vegetation, consider where you place it and what it will look like in 10 or 20 years.
A free printable brochure, Right Tree, Right Place, offers SCE customers safety tips and a sampling of utility-friendly tree species recommended for planting.
Properly maintaining trees and vegetation near electrical equipment can help prevent power outages and decrease the risk of sparking a fire.
Not all electrical poles or towers require vegetation clearance. SCE is required by regulation to maintain bare-soil vegetation clearances at the base of certain poles and towers in the Cal-FIRE State Responsibility Area. Additionally, SCE strives to maintain vegetation clearances at the base of select poles in high-fire-risk areas (HFRA).
- Customers will receive a door hanger from an SCE-approved contractor to inform them about necessary vegetation activities on the property.
- SCE-approved contractors will inspect the base of the pole or tower and take photographs of it.
- As needed, SCE-approved contractors will remove all brush from the base of the pole or tower, 10 feet around by 8 feet high. If the customer intended and maintained vegetation exists, the SCE-approved contractor may seek customer consent to remove it and clear all vegetation to bare soil.
- In certain high-fire risk areas, SCE-approved contractors may revisit the pole or tower a second time in the calendar year to inspect and maintain any vegetation regrowth.
- All brush removal activities are done as part of SCE’s vegetation maintenance work at no additional cost to the customer.

Enhancing Grid Reliability
Transmission Vegetation Management and Integrated Vegetation Management
Class name

A reliable electricity transmission system is crucial for an uninterrupted power supply, but vegetation growth near power lines can lead to outages and risks. Transmission Vegetation Management and Integrated Vegetation Management are vital strategies for addressing these challenges.
Transmission Vegetation Management involves systematic inspection, pruning, and vegetation removal near power lines. A key consideration is the requirement for greater clearances from vegetation to conductors. This is especially important for transmission lines, which carry higher voltages than distribution lines, resulting in a higher potential for electrical flashover risk. Flashovers occur when electricity jumps from the conductor to nearby vegetation, causing outages and potential fires. To prevent these hazards, Transmission Vegetation Management ensures a sufficient distance between vegetation and transmission lines.
An outage in a transmission line can have far-reaching consequences. These lines are responsible for carrying electricity across long distances, often connecting power plants to distant communities. When an outage occurs, large areas can be left without electricity, affecting homes, businesses, hospitals, and critical infrastructure. The economic and social impact of such outages can be significant, highlighting the importance of robust Transmission Vegetation Management practices.
To ensure effective Transmission Vegetation Management, various regulatory bodies like the North American Electric Reliability Corporation (NERC), the Federal Energy Regulatory Commission (FERC), and the California Public Utilities Commission (CPUC) have established guidelines and regulations. These agencies work to standardize Transmission Vegetation Management protocols, emphasizing the importance of regular inspections, maintenance, and adherence to safety protocols. By complying with these regulations, utilities can enhance grid reliability and protect both the power infrastructure and the environment.
Integrated Vegetation Management (IVM) also plays a crucial role by integrating ecological considerations into vegetation management. This approach seeks to balance power system safety and environmental preservation. By selecting compatible vegetation species and adopting eco-friendly controls, IVM minimizes the impact of vegetation management on the ecosystem while ensuring reliable power transmission.
