Generator Interconnection

Interconnections Collage 

In this section you will find information pertaining to the safe interconnection of generators to the CL&P electric distribution system and information on net metering(PDF). Generators include photovoltaic arrays (solar panels), mini-turbines, wind turbines, cogeneration units and micro turbines, to name a few. Interconnection occurs whenever your generating equipment (including inverters and batteries) is simultaneously connected to your electrical system and to CL&P’s electric distribution system.

See Frequently Asked Questions for more information.
