When and How to Trim Trees Near Power Lines in South Carolina

Big Trimming Means Keeping Trees Away From Electrical Lines

Big trimming is the removal of large branches or entire sections of trees that grow too close to power lines. In South Carolina, this work is usually done by utility companies or licensed contractors they hire, not by homeowners. The goal is to prevent branches from touching live wires, which can cause outages, fires, and serious injury or death.

If you see branches hanging over power lines on your property or a neighbor's, you should report it to your local utility company rather than attempt removal yourself. Touching or cutting branches near energized lines is extremely dangerous. South Carolina utilities like Dominion Energy, Duke Energy, and Santee Cooper all maintain vegetation management programs and respond to hazard reports.

Understanding when trimming is necessary, who does it, and what to expect helps you protect your property and stay safe around electrical infrastructure.

Key Takeaways

• Never trim branches near power lines yourself—contact your utility company to report the hazard and request trimming.
• Utility companies trim trees on their own schedule as part of vegetation management, but you can report urgent hazards by phone or online.
• Trees growing within 10 to 15 feet of power lines (distance varies by voltage) may need trimming to prevent outages and safety risks.
• If a tree is on your property, the utility company typically trims it at no cost to you; if it's on public land, the city or county handles it.
• After trimming, branches are usually chipped or removed by the utility contractor, though you should confirm what happens to debris on your property.

Why Power Companies Trim Trees in South Carolina

Branches touching or rubbing against power lines cause most outages in South Carolina during storms and high winds. When a branch makes contact with a live wire, it can trip the circuit, shut off power to entire neighborhoods, or start a fire. Heavy ice or wet snow accumulation on branches also increases the risk of limbs breaking and falling onto lines.

Utility companies trim trees proactively to reduce these risks and keep the grid reliable. They follow a cycle—typically every three to five years—trimming vegetation in different service areas. The work is part of their operating budget and is passed along to customers through rates, so you do not pay separately for trimming on your property.

South Carolina law allows utilities to trim trees on private property without your permission if the branches pose a hazard to power lines. However, most companies notify property owners before work begins or ask for access in advance.

How to Report a Tree Hazard to Your Utility

If you notice branches hanging over power lines, contact your utility company directly. Dominion Energy, Duke Energy, and Santee Cooper all have online reporting tools and phone lines for vegetation hazards. You can usually report through their website by describing the location and uploading a photo, or call their customer service number during business hours.

When you report, provide the street address, a description of which lines are affected (if you can see them), and how close the branches are. If the hazard is creating an immediate safety risk—such as a branch actively touching a line or a tree leaning dangerously—mention that in your report. Urgent hazards may be prioritized over routine trimming.

After you report, the utility will send a crew to assess the situation. If trimming is needed, they will schedule it and may contact you to confirm access to your property. The entire process from report to completion typically takes a few weeks, though urgent cases move faster.

What Happens During Big Trimming Work

When a utility contractor arrives to trim, they use bucket trucks, chippers, and hand tools to remove branches safely while keeping the work area clear of the power lines. The crew will typically trim back to a safe distance—usually 10 to 15 feet from the line, though the exact distance depends on the voltage and type of line. They may remove entire limbs or sections of the tree to prevent future growth into the lines.

The work is done by trained arborists or line clearance specialists who understand electrical safety. They do not remove healthy trees unless the tree is too close to the line and cannot be safely trimmed. If a tree is dead, diseased, or poses a structural risk, the utility may recommend removal, but that decision is usually yours to make.

Debris from trimming is typically chipped on-site or hauled away by the contractor. If you want to keep the wood for firewood or mulch, ask the crew before they leave—some contractors will leave it for you, while others remove everything as part of the job.

Trees on Your Property Versus Public Land

If the tree is rooted on your property, the utility company pays for trimming and handles the work at no cost to you. You own the tree, but the utility has the legal right to trim it to protect the lines. After trimming, the tree remains your responsibility—if it becomes diseased or unstable, you may need to remove it yourself or hire an arborist.

If the tree is on public land—such as a street right-of-way, park, or city-owned property—the city or county usually handles trimming. You can still report the hazard to your utility, and they will coordinate with the municipality. Public trees sometimes take longer to trim because the city has to schedule the work through its own maintenance budget.

In either case, you should not trim the tree yourself if power lines are involved. Even if you own the tree, cutting near live wires is illegal and dangerous.

Safety Rules for Trees and Power Lines

South Carolina law prohibits anyone except authorized utility workers from trimming, cutting, or removing trees within a certain distance of power lines. Violating this rule can result in fines and criminal charges. More importantly, contact with a live wire can cause electrocution, severe burns, or death.

If you are planning landscaping or tree removal on your property, call 811 before you dig or cut. This free service marks underground utilities so you know where power, gas, water, and communications lines are located. For overhead lines, contact your utility company directly and ask them to mark the lines or advise you on safe distances.

Never use a metal ladder, metal pruning tools, or conductive equipment near power lines. Never trim trees during or immediately after storms when lines may be damaged or exposed. If a tree falls on a power line, stay away from it and call 911 and your utility company immediately.

What to Do if Trimming Damages Your Tree

Utility trimming sometimes leaves a tree looking unbalanced or removes more growth than you expected. This is normal and usually does not harm the tree long-term. Trees recover from utility trimming and often grow back fuller within a season or two. However, if you believe the trimming was excessive or damaged the tree's health, you can contact the utility company to discuss your concerns.

If the trimming exposes the tree to disease or pest problems, that is typically your responsibility as the property owner. You may want to have a certified arborist inspect the tree after trimming to assess its health and recommend care if needed. Some trees benefit from pruning and actually grow stronger afterward.

If a utility contractor damages your property during trimming—such as breaking a fence, damaging a roof, or harming landscaping—report it to the utility company in writing with photos. Most utilities have a claims process for property damage caused by their contractors.

Frequently Asked Questions

Can I trim branches myself if they are on my property?

No, not if the branches are near power lines. Even on your own property, trimming near electrical lines is illegal and extremely dangerous. Contact your utility company to report the hazard, and they will handle the trimming at no cost to you.

How long does it take for the utility to trim after I report it?

Routine trimming requests typically take two to four weeks, depending on the utility's schedule and workload. Urgent hazards—such as a branch actively touching a line—may be addressed within days. You can ask the utility for an estimated timeline when you report.

Will trimming kill my tree?

Utility trimming rarely kills a healthy tree. Trees are resilient and recover from branch removal. However, if the tree is already diseased or stressed, heavy trimming may weaken it further. A certified arborist can assess your tree's health after trimming if you are concerned.

What if my neighbor's tree is hanging over my power line?

Report it to your utility company with the neighbor's address. The utility will contact the neighbor and arrange access to trim the tree. You do not need to involve your neighbor directly—the utility handles the communication and coordination.

Do I have to let the utility company on my property?

In South Carolina, utility companies have the legal right to access private property to trim trees that pose a hazard to power lines. However, most utilities prefer to notify you in advance and work cooperatively. If you have concerns about access, contact the utility to discuss timing or specific areas of your property.
