Customer Owned Generation Facility Interconnection Process


Introduction

This process and accompanying guidelines have been developed by the City of Groton Department of Utilities, Electric Division (GU) or (Division) to assist Customers wishing to generate power and to interconnect with the Division’s Electric Power System (EPS). 

GU Electric Division is responsible for the distribution of electric power throughout the City of Groton and portions of the Town of Groton, Connecticut. GU must ensure that any interconnections to the EPS are performed in a safe and reliable fashion. To this end, protocols and procedures are outlined in this Guideline document. 

These Guidelines provide a means for the Customer and GU to work together toward the common goal of a successful interconnection. In working together, GU is always willing to consider case specific exemptions to the Guidelines due to changes of applicable regulations, advances in technology, etc.
