Become a Local Generation Facility

We want to support and expedite your efforts to establish a local generation facility within our electric service territory. Whether you are a customer considering local generation for the first time, or an experienced contractor looking for detailed specifications, we have useful information to help you learn about your options, guide you through the application process, and get the job done.

Local Generation Basics

We define local generation as a generally small (up to 20 MW) electric production facility that is dedicated to the support of nearby associated load. For greater efficiency and cost savings, combined heat and power can produce heat as an energy product. Local generation can use both renewable (photovoltaic, wind, water, farm waste, etc.) and non-renewable energy sources (natural gas or other fossil fuels for conventional engines, turbines, and fuel cells). Regardless of the kind of local generation electric output (AC or DC at various voltage levels), your facility must conform to company standards when connected to Con Edison’s electric, gas, or steam system.

Our Policy 

You can operate your generating equipment in parallel with our electric system, as long as doing so doesn’t cause an adverse effect on our other customers, equipment, personnel, or the quality of service. We may ask you to install certain protective devices (relays, circuit breakers, etc.) at all locations where you plan to operate generation in parallel with our system. You may also purchase natural gas or steam from Con Edison if you need it to operate your local generation system. 

Hosting Capacity

Hosting capacity is the amount of distributed energy resources that can be accommodated without adversely impacting power quality or reliability under existing control configurations and without requiring infrastructure upgrades.

In the map, triangles represent locations where we anticipate we can accept solar private generation output with little to no additional cost to the project. The larger the triangle, the higher the likelihood there will be no or little additional cost to interconnect in that area. We have initially focused on developing maps for our low-voltage network areas and will include non-network areas in the future.

Peak Load Duration Curves

We have forecasted 2016 network-level 24-hour peak load duration curves and network-level 24-hour minimum load duration curves based on 2015 historical loads. 

These curves have been plotted on a single graph along with a capacity curve that indicates the remaining capacity at the substation level. In the case where a substation feeds multiple networks, the capacity has been proportionally rated based on network peak values. Additionally, each network load curve lists the five-year compound annual growth rate.

Historical 8760 Load Data

We have data for each network, including the date/time and load in MW. The 8760 load data coincides with the all-time system peak in July 2013. The 8760 load curve data is a raw data export from a historical archiving system and has not been reviewed and processed (e.g., weather adjusted, evaluated for meter error, fully adjusted to account for distributed energy resource load modifiers, etc.) by the methodology applied to the peak hour forecast.
