Connecticut allows municipalities to offer a property tax exemption lasting up to 15 years for qualifying cogeneration systems installed on or after July 1, 2007. Municipalities can also adopt exemptions for commercial or industrial Class I renewable resources including hydropower facilities, solar thermal, or geothermal renewable energy resources. Only a facility with a capacity that does not exceed the location’s load and which was installed between January 1, 2010 and December 31, 2013 is eligible for the exemption. Systems installed after 2013 will be eligible for a statewide exemption.
