Service Upgrades in Brooklyn & Manhattan

Electrical service upgrades for brownstones, co-ops, condos and commercial buildings: more capacity, permitted and coordinated with Con Edison from start to finish.

A service upgrade replaces the equipment that brings power into a building, from the service entrance and meter to the main panel, so the property can safely carry more load. Many older Brooklyn and Manhattan buildings still run on 60 or 100 amp services that were never designed for central air, heat pumps, induction cooking or EV charging.

We size the new service from a load calculation, file the electrical permit with the NYC Department of Buildings, submit the service application to Con Edison, and schedule the changeover to keep the time without power as short as possible.

  • Load calculation and service sizing
  • DOB permit and Con Edison coordination
  • Residential, multifamily and commercial services

Large building service upgrades

We upgrade services from a single brownstone to large commercial and multifamily buildings, including the Con Edison coordination and DOB reviews that large services require.

Manhattan

1,200 to 2,700 amp service upgrade

We upgraded a Manhattan building's electrical service from 1,200 amps to 2,700 amps, filed under our NYC DOB license and coordinated with Con Edison.

Brooklyn · Commercial

New 800 amp service for a commercial space

In Brooklyn we added an 800 amp service for a commercial space in a building whose total service is over 4,000 amps. At that size, the work went through the NYC Department of Buildings EPR process, which we handled with the DOB.

Replacing panels too? See our panel replacement projects, including 120 Federal Pacific panels retrofitted in Queens.

Preparing buildings for all-electric equipment

New York City is moving buildings away from gas. Replacing boilers, furnaces and gas ranges with heat pumps and induction cooking adds significant electrical load, and many buildings need a larger service before that equipment can be installed. We assess your existing capacity and plan the upgrade around the equipment you intend to add.

Looking for an electrician near you? See our Brooklyn electrician and Manhattan electrician pages.

When a service upgrade makes sense

Common signs: a 60 or 100 amp service, a fuse box or crowded panel, breakers that trip when the air conditioning or appliances run, or plans for a renovation, central air, heat pumps, an induction range or EV charging.

We review your existing service on a site visit and tell you what it can support. If an upgrade is needed, you get a written scope and estimate before any work starts.

How it works

How an electrical service upgrade works in NYC

Most service upgrades follow the same five steps. We handle the permits and the Con Edison coordination, so you deal with one contractor from start to finish.

  1. STEP 01

    Site survey & load calculation

    We look at your existing service and panel and calculate the power you need now and for planned HVAC, cooking, and EV charging.

  2. STEP 02

    DOB electrical permit

    We file the electrical permit with the NYC Department of Buildings under our license, #4876.

  3. STEP 03

    Con Edison application

    We submit the service request to Con Edison and coordinate the meter and service work with them.

  4. STEP 04

    Installation

    New service equipment, meter, and panel, installed clean, organized, and labeled.

  5. STEP 05

    Inspection & energize

    The DOB inspects the work, and Con Edison connects your new service.
