Guides & Specifications for Distributed Generation
Overview
Explore all the technical documents and specifications you need to design, permit, and interconnect a distributed generation (DG) system on the Con Edison grid.
General Guides
Use the links below to understand the ins and outs of various DG sources. If you’re not sure which guide applies. start with the Solar or Storage guide. Then check the Utility Process Guide to see if your project falls outside standard rules

Specs for Transfer Switch Types
Break-Before-Make Specifications (EO-2113): Disconnects from utility before switching to generator. Simple and cost-effective, but causes a brief outage.
Make-Before-Break Specifications (EO-2134): Allows seamless switching between grid and generator with no power interruption.
Specs for High-Tension & Non-Network Systems
High-Tension Design Requirements (EO-2022): Applies to substations connected to network or non-network systems.
Non-Network Distribution Interconnection (EO-10215): Covers Auto Loop, 4 kV Grid, Step Down Feeder systems and more.
Electrical Service to Dispersed Generation Customers (EO-2115): Requirements for small and independent power producers.
Specs for Microgrid System Requirements
Microgrid Technical Requirements (EO-2161): Technical standards for interconnecting microgrid systems to Con Edison’s distribution grid. Ideal for campuses, multi-building developments, or industrial parks.
