How Our Repairs Keep Service Reliable

We are always working to maintain our equipment and keep your service reliable. Find out more about typical work you may see us doing in New York City streets.

Transformer Replacements


Transformers take the high-voltage electricity that comes from power lines and reduce it to a low 110- or 220-volt power that’s safe for you to use in your home. Typically, our transformers are located under public sidewalks. We periodically inspect and monitor our transformers, and replace them as needed.

Securing the Work Site

First, we secure the work site with barriers and markers to keep the area safe. We may need to break up the sidewalk to remove and replace the existing transformer.

Temporary Cables


Con Edison may install temporary cables to keep power flowing to a building when a customer's electric service needs repairs. These cables are typically run from a structure in the street, over the sidewalk, and into the building, where they connect to the customer's electrical system. The cables will stay in place until repairs are made. They will be blocked off with barricades, and ramps will be placed over them on sidewalks to keep the area safe.

Equipment Responsibility

Sometimes we need to repair our equipment, sometimes the customer needs to repair the building's electrical system, and sometimes repairs are needed on both systems. We will let customers know if they are responsible for repairs on their equipment.

Water Leaks


The typical New York City building has utility cables, pipes, ducts, and wires entering through openings in the foundation or basement wall. Sometimes, water can leak through these entry points, or through cracks or holes in your foundation or basement wall.

If you find a leak and think it could be caused by a Con Edison duct, structure, or pipe, call us at 1-800-75-CONED and we'll take a look. We may need to enter your premises to figure out the source of the leak.

How Water Gets In

Water can leak into your building through openings for utility cables and pipes, or through cracks and holes in the foundation.
