Interruptible Service

Interruptible Service

Liberty Utilities has seven classes of service, with different rates for each class of service. Interruptible service is classified as Service Classification No. 4. Interruptible customers usually pay the lowest rates for gas. In return, however, interruptible customers must have the ability to switch to an alternative fuel (e.g. #6 oil) at the Company’s request, when there is a high demand for gas by other customers, usually in the coldest periods of the year. These customers must contract to use a minimum of 200 Mcf (thousand cubic feet) per day and 250,000 therms per year. The Company, in its sole discretion, acting reasonably, shall determine the volume of interruptible gas which it shall have available under this service classification.
