sec.121Purpose of electricity restriction regulations

### sec.121 Purpose of electricity restriction regulations The purpose of an electricity restriction regulation is to restrict the use of electricity provided through a transmission grid or supply network or part of a transmission grid or supply network to ensure there is a regular, economically efficient and constant supply of electricity within the available supply capacity of the transmission grid or supply network or part of the transmission grid or supply network. There are limitations in the capacity of generating plant or other works of an electricity entity. The use of large appliances (for example, industrial welders and large self-contained refrigerative air conditioners) may affect the quality of electricity supply to customers by causing unacceptable variations in voltage. It may not be economically practicable to increase the electricity entity’s generating plant capacity to cater for the large appliances. In the interests of maintaining supply for all customers, it may be necessary or desirable to make an electricity restriction regulation to restrict the use of the large appliances.
