Today, Connecticut currently has 187 CHP installations. Of the 187, 13 are located in hospitals or healthcare centers, 24 in nursing homes, 9 in colleges or universities, and 28 are in multi-family buildings, with many others employed in agricultural, private, or other uses. Altogether, these systems boast a capacity of over 741 MW. This information along with further details can be found at the U.S. DOE Combined Heat and Power Installation Database.[1] 

In a study conducted by the Department of Energy in March 2016, it was apparent Connecticut's CHP capacity has room to grow. Connecticut has 1,323 MW of CHP potential at over 3,000 sites. Most of this potential (~800 MW) is in the commercial sector including office buildings, colleges/universities, government buildings, multifamily buildings, and hospitals. 415 MW of potential exists in the industrial sector, and the study identified over 100 MW of district energy potential.

A current list of CHP units in Connecticut is available through this ICF International Database.

Policy, Programs & Incentives:

Connecticut has a number of programs and incentives designed to promote and support new and existing CHP projects. Connecticut's CT Clean Energy Fund continues to fund renewable projects, including CHP. The fund is controlled by the CT Green Bank, which is authorized to invest in CHP projects and other renewable or efficiency projects.[1] According to its annual report, the CT Green Bank had invested $95,129,679 total into various renewable or efficiency projects in 2015.[2] One particular program funded through the CT Green Bank is the C-PACE program. From its website, the "Commercial Property Assessed Clean Energy (C-PACE) is an innovative program that is helping commercial, industrial and multi-family property owners access affordable, long-term financing for smart energy upgrades to their buildings."[3] CHP end-users and developers can apply directly on their website.

The Connecticut Department of Energy and Environmental Protection (DEEP) developed a permit-by-rule (PBR) which expedites permit processing time that would otherwise take about six months. DEEP also released a draft Integrated Resource Plan in 2012. The plan proposed to offer incentives of up to $450/ kWh for up to 160 MW of new CHP capacity in the state. The incentives will decline over time, however.[4] In addition, a Microgrid Grant and Loan Pilot Program was established to support local distributed energy generation at critical facilities in the state. The program considers applications requesting financial support for the development of microgrids that are powered by CHP and other renewable energy sources. "The state also passed legislation in 2016 to expand the DEEP microgrid program funding for additional types of costs associated with microgrids. Grants and loans can now be used to cover costs associated with distributed generation infrastructure." [5]
