Responsibility for underground power lines typically falls on the local utility company or provider in a given area, which is responsible for the installation, maintenance, and repairs of these lines.
Electric Company Responsibility
Your electric company is only responsible for maintaining and repairing the following items: Wooden utility poles. Overhead and underground power lines. Electric service lines that run between utility poles and to your home.
Your utility company is usually responsible for the wires connecting your home to the pole. Homeowners are responsible for almost all other electrical components.
A utility company owns and maintains public utility lines and cables. They will determine where the lines end. Private utility lines go beyond that point and must be owned and maintained by the property owner.
The customer/owner is responsible for installing, maintaining and repairing all equipment beyond the service connection point except for the electric meter.
The average cost to run power underground is $10 to $25 per foot, or $5,000 to $12,500 for 500' of new electrical lines. Overhead power line installation costs $5 to $15 per foot, or $4,000 to $7,500 for 500'. The cost to bury existing power lines is $2,000 to $6,000. Get free estimates from wiring installers near you.
Typically the utility company owns the overhead wire and maintains the splices at the top of the weatherhead. The home owner is normally responsible for the meter socket, mast, and service entrance conductors.
In most cases, the utility owns everything up to the service connection point. However, they control everything up to the output side of the meter and only they may touch it while it is electrified. There is typically a seal on the meter to enforce this.
Typically, residential powerlines are buried between 18 to 24 inches (45 to 60 cm) deep. Local building codes and utility regulations often dictate the minimum depth to which power lines must be buried to ensure safety and minimize the risk of accidental damage.
While underground lines are protected from wind, wildfires and tree branches, they are vulnerable to earthquakes and flooding. They are also more expensive to build and maintain. By comparison, it costs approximately 3-5x more per foot to construct underground power lines versus overhead lines.
In electric power distribution, a service drop is an overhead electrical line running from a utility pole, to a customer's building or other premises. It is the point where electric utilities provide power to their customers.
It depends. In some places (like Dallas, TX) the transmission utility owns the land under transmission lines. In other areas, the utility leases or has an easement for the lines. Distribution lines are usually on public right of way or utility easements.
Although undergrounding may eliminate the causes of some outages, underground cable and equipment can still fail, and other issues can lead to power outages.
» Homeowners own and are responsible for electrical equipment attached to the house (service stack, attachment hardware, riser and meter box) and the pole with an attached meter box for mobile or manufactured homes. » FPL is responsible for the wire or service line to the house and the electric meter.
Your utility owns the electric meter for home energy measurement, and is responsible for installing, maintaining, and reading it. Tampering with a residential power meter is not authorized, and is a punishable offense. (Not to mention it can be highly dangerous!)
Hitting underground utility lines can cause: Immediate Dangers: Gas Leaks: Risks of explosions or fires, especially in dense areas. Electrical Hazards: Potential for shocks, electrocution, or fires, posing risks to everyone nearby.
Your state 811 center will inform utility operators in your area that they need to mark any buried utility lines on your property with paint or flags.
There is no prescribed depth that you are allowed to dig before you call 811. Regardless of whether you are installing a few small shrubs or putting in some fence posts, it is important to reach out to the authorities to make sure you do not hit anything important.
For one thing, the service drop belongs to the utility company, not to the homeowner. For another, power in the service drop cables can be shut off only by the utility company. Homeowners also should not attempt any work on the cables between the service drop and the home's electrical service panel.
Electrical circuits are generally placed underground to protect the lines from high winds, ice and other damaging elements. Underground installation also improves aesthetics, but is usually more costly. For this reason, most utilities will install underground lines at the customer's request and cost.
If you're building a simple shallow paver patio, with the right precautions you should be able to build it on top of existing lines. Call Before You Dig: Before you begin, dial 811 to schedule an appointment with your local utility locator service.
Usually, the utility is responsible up to the point of connection, which is usually the splices outside of the weatherhead. Some utilities only have responsibility to the pole, and some to the meter. You would have to contact your utility company to be sure which applies here.
A: Under California law, utilities like Southern California Edison generally have the right to install and maintain their infrastructure on private properties through easements or utility rights-of-way.
The Grid Code details the technical requirements for connecting to and using the National Electricity Transmission System (NETS). Compliance with the Grid Code is one of the requirements of the Connection and Use of System Code (CUSC).
