Please answer the following questions regarding how electrical facilities may be extended to your property.
1.

Select the state where you would like a ballpark estimate for new electric service.

2.

What is the distance in feet from the nearest electrical facility to where your meter would be located?

Measure along a clear, accessible, path you suspect the power lines would be constructed. Enter a footage less than 2,640' (1/2 mile).

Choose one of the seven illustrations below that best reflects the existing electrical facilities at your site and how you think power might be extended to your home.

For new extensions, orange represents low-voltage lines that serve the home, while red indicates high-voltage lines that may be required due to distance or load. Dashed lines represent underground facilities.

Be sure to pick the illustration that best indicates whether the existing power lines, as well as the new extension to your home, are underground or overhead, or could be both.

Is the nearest electrical facility a transformer (either ground-level padmount or overhead on a pole)?

What is a transformer?

Here are some clues to determine if the nearest electrical facility you are measuring from has a transformer or not.

a. Facilities with transformers:

Pole with transformer Padmount transformer

b. These are NOT transformers:

Pole without transformer Pole without transformer Padmount switch cabinet
To determine if padmount equipment is a transformer, consider the following:

  • Transformers are mostly square. Switches are more rectangular being more wide than deep.

  • Transformers may produce a slight humming sound.

  • Transformers may have stickers with sizes like: 25, 50, 75, 100, or 167.

  • Transformers have nameplates with clues like Kva size, High & Low voltages (look for 120/240), or the word "transformer".
