Welcome to Con Edison's Distributed Generation Web site. Our mission is to support and expedite your efforts to establish a distributed generation (DG) facility that will operate within our electric service territory. Whether you are a customer considering DG for the first time, or an experienced contractor looking for detailed specifications, you will find useful information here to help you learn about DG options, guide you through the application process, and get the job done.
Con Edison defines a distributed generation (DG) facility 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 (CHP) DG can produce heat as an energy product. DG can utilize 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 DG electric output (AC or DC at various voltage levels), the DG must conform to company standards when connected to the utility’s electric, gas or steam system.
Con Edison permits any customer to operate generating equipment in parallel with the company’s electric system, provided there is no adverse effect on the company’s other customers, equipment, or personnel, or the quality of service. Certain protective devices (relays, circuit breakers, etc.), when specified by the company, must be installed at all locations where the customer desires to operate generation in parallel with the company’s system. Customers may also purchase natural gas or steam from the Company if required for operation of their DG.
