Exemption from Electric Generation Tax

February 11, 2015


NOTE: Electric Generation Tax expired on October 1, 2013. Electric generation facilities are no longer required to pay generation tax.

In 2011, Connecticut created a new tax requiring electric power plants in the state that generate and upload electricity to the regional bulk power grid to pay $2.50 per megawatt hour. Renewable energy facilities, resource recovery facility, and customer-sited facilities are exempt from the tax. The tax and related exemptions are scheduled to sunset October 1, 2013.
