Vt. Stat. tit. 30 § 3007
Each incorporator of a cooperative shall be a member thereof, but no other person may become a member thereof unless such other person uses electric energy or other services, goods, or products furnished by the cooperative when they are made available through its electric distribution facilities, or a person may become a member by purchasing and paying the cooperative for renewable energy certificates or other environmental attributes associated with the generation of electricity. A member of a cooperative who ceases to use electric energy shall cease to be a member if he or she does not use electric energy supplied by the cooperative within six months after it is made available, or if electric energy is not made available by the cooperative within two years after he or she becomes a member or some lesser period as the bylaws of the cooperative may provide. Two or more owners or occupants of property served by a cooperative may hold a joint membership in a cooperative. Membership in a cooperative shall not be transferable, except as provided by the bylaws. The bylaws may prescribe additional qualifications and limitations in respect to membership.
