About Us


Energy Resource Group Technologies, Inc., (ERGT) founded 1995, is Connecticut’s oldest Energy Conservation Services Company and is located in the Northford section of New Haven County.

Since our founding, we have provided a variety of residential energy conservation services supported by Energize Connecticut and the Connecticut Energy Efficiency Fund and administered by Eversource Energy, The United Illuminating Company (UI), Southern Connecticut Gas Company (SCG) and Connecticut Natural Gas (CNG).

We are well staffed with friendly and knowledgeable technicians that are here to help you save energy. Our primary mission and goal is to help educate the public on how to reduce their high energy usage caused by excessive heating and cooling loads, insufficient insulation levels, high wattage lighting, and older appliances and HVAC equipment.

We have serviced tens of thousands of residents of the State of Connecticut through a variety of programs and are proud of our track record. Many times Connecticut low and fixed income residents feel under served and we have helped bridge the gap by spending the extra time necessary to explain how these services can benefit them. Our staff have received many compliments from grateful recipients of energy conservation services and we always go the extra mile to help achieve the goals of the program and meeting the customers’ expectations.

We have also provided weatherization, insulation and lighting services for the State of Connecticut Department of Developmental Services Multi-Unit Residential properties to help reduce our State Agencies energy consumption.

All of our Lead Technicians are BPI Building Analyst, Building Envelope and BPI Multi Family Certified and we are an EPA Lead Safe Certified Company.
