Distributed Generation

What is Distributed Generation?
Distributed Generation produces electricity from many small energy sources including solar, wind, fuel cell, or micro turbines. Commonly known as on-site generation, co-generation, combined heat and power dispersed generation or distributed energy which in turn expands energy options for our customers.

Generator Interconnections
There are two major types of interconnection applications we receive here at UI. The first type is Certified Inverter Based Generating Facilities which encompasses the most common smaller generator sizes. The second type is the Fast Track and Study Process Generating Facilities which primarily includes uncertified inverters and larger generator sizes.

Below are the guidelines for each interconnection type.

  Basic Interconnection   

 

Certified Inverter Based Generating Facilities, 10kW and Less
This type of interconnection and process is for a certified inverter-based device producing 10kW and less of energy. The inverter is considered approved if it is certified to UL-1741 and is in compliance with IEEE C62.41 and C62.45.

Fast Track & Study Process Generating Facilities
These types of interconnections and processes are primarily for non-certified inverter-based, induction, or synchronous generators producing between 10kW-20MW of energy.

There are two advanced application process categories, Fast Track Process and Study Process.


 

1. Fast Track Process
Interconnecting facilities such as induction, synchronous, certified inverter based generators or other generators producing between 10kW -2MW and successfully passes the screen criteria set forth in Section 4.2.1 of Connecticut State Guidelines qualify for the Fast Track Process.

 

   

2. Study Process
Interconnecting facilities such as induction, synchronous, certified inverter based generators or other generators producing between 2MW – 20MW or facilities that fail both Fast Track screen criteria and supplemental modifications will require additional (feasibility, facility, and Impact) studies and acceptance of additional modifications to determine interconnection consistent with safety, reliability, and power quality standards.
