WCL / ELECTRICAL CONNECTION GUIDE
Underground Electrical Service Cost
Underground residential service is often less about one fixed price and more about the route. Trench length, soil, conduit, crossings, restoration and utility specifications determine how complex the job becomes.
Trenching and conduit
A clear soil trench is different from rock excavation, a driveway crossing or directional boring. Separate trenching from electrical equipment so site-work changes do not get hidden inside a lump-sum price.
Distance and conductor route
Longer underground runs can increase conductor, conduit and pulling effort. Route geometry, bends and pull points can matter as much as straight-line distance.
Driveways and hardscape
Concrete, asphalt, retaining walls and finished landscaping can add cutting, boring and restoration work that is not captured by a basic electrical rate.
Utility specification
Depth, conduit type, warning tape, transformer location, meter position and inspection sequence may be dictated by the serving utility or local authority.
Use the electricity hookup calculator
Model the project with editable assumptions for utility fees, distance, line work, meter equipment, panel work, permits and contingency in the Electricity Hookup Cost Calculator.

Frequently asked questions
Why does underground service vary so much in price?
The route can require simple trenching or difficult excavation, boring, long conduit runs and restoration. Local utility specifications also vary.
Should trenching be quoted separately?
It is often useful to separate trenching/site work from electrical equipment and labor so you can see which part of the project is driving cost.
Can I trench before the utility approves the design?
Do not assume the route, depth or conduit requirement. Confirm the utility and local requirements before permanent site work begins.
