Description

Under the Energy Tax Reform Act, a sales tax is imposed on natural gas and electricity. However, there is an exemption for the purchase and use of natural gas and utility service that is used for cogeneration if the cogeneration facility was in operation or had filed a operating or construction permit on or before March 10, 1997. To apply for the exemption, the cogeneration facility will issue an Exempt Use Certificate (ST-4) to natural gas vendors.

If the cogeneration facility came into operation after March 10, 1997, the purchase of natural gas and utility service may be tax exempt if it is used to generate electricity that is (1) used for resale or (2) sold to an end user other than the owner of the cogeneration facility. A Direct Pay Certificate will be issued to the facility and the facility will self-assess on a quarterly basis that the electricity generated fits into one of these two categories.
