Connecticut’s 1998 electric restructuring legislation established the Renewable Energy Investment Fund.*  The Renewable Energy Investment Fund was later renamed the Clean Energy Fund, which the Clean Energy Finance and Investment Authority (CEFIA)** -- a quasi-governmental investment organization -- was given the authority to administer. In operation since 2000, the Clean Energy Fund has aimed to develop, invest in, and promote, sustainable energy sources. A surcharge on Connecticut ratepayers' utility bills provides the funding for the Clean Energy Fund, and the charge currently stands at "not less than" $0.001 per kWh (1 mill per kWh).

CEFIA was given a significant amount

In April 2004, Connecticut's governor signed an executive order directing state government agencies and universities to purchase an increasing amount of electricity generated by renewable resources. Under terms of the order, the state government has a goal to increase "Class I" renewable energy purchases to 20% of electricity used in 2010, 50% in 2020 and 100% in 2050. The order also authorizes the use of savings generated by state energy efficiency and conservation projects to fund green power purchases.

Class I renewable energy resources include solar, wind, new sustainable biomass, landfill gas, fuel cells (using renewable or non-renewable fuels), ocean

Note:  In 2010, the Federal Housing Finance Agency (FHFA), which has authority over mortgage underwriters Fannie Mae and Freddie Mac, directed these enterprises against purchasing mortgages of homes with a PACE lien due to its senior status above a mortgage. Most residential PACE activity subsided following this directive; however, some residential PACE programs are now operating with loan loss reserve funds, appropriate disclosures, or other protections meant to address FHFA's concerns. Commercial PACE programs were not directly affected by FHFA’s actions, as Fannie Mae and Freddie Mac do not underwrite commercial mortgages.

Residents or businesses can choose to invest in, or lease, a renewable energy system installation on the rooftops of their homes or businesses, or on their properties. However, some Connecticut residents and businesses are either not able to, or elect not to, invest in or lease an individual property installation for a variety of reasons (e.g., high installation costs, unsuitable rooftop orientation, shaded property, or because they rent instead of own their properties). Subscription to a shared clean energy facility (SCEF) provides an option that can be used to overcome such barriers, thereby expanding access to renewable energy to more
