Prism Propane was formed in 1998 as a for-profit company and affiliate of the HWEC non-profit organization to offer economically priced propane gas services to customers in Allen, Hancock, Hardin, Henry, Putnam, Sandusky, Seneca, Wyandot and Wood counties. Since that time, it has grown to become one of the leading local propane companies offering 24-hour emergency service, financing plans and online customer registration.
