13 September 2010 Licence type Scope Special licence Isolated system operations (b) to generate electricity at specified electricity generating plants; to sell electricity to electricity entities holding a generation licence or a retail licence; to sell electricity to customers, but only in respect of electrical installations or premises which are situated within specified locations; and to own and operate an electricity network within specified geographic areas and connect that network to another specified electricity network. System Control licence (c) to monitor and control the operation of the power system with a view to ensuring that the system operates safely and securely, including by issuing directions to electricity entities that are engaged in the operation of the power system, or contribute electricity to, or take electricity from, the power system (a) An Independent Power Producer licence is a cut down version of a generation licence for those parties who do not wish to participate fully in the electricity supply market and instead generate electricity under contract for another generator. (b) An isolated system operations licence is a combination generation, network and retail licence for entities operating in remote locations, for example where a mining company supplies electricity to a nearby town that predominantly houses workers associated with the mine. (c) A system control licence is only be issued where the power system is of sufficient size and complexity to warrant monitoring and control by an arms length system controller. In isolated communities with a single generator of electricity, management of system loads and frequency control is undertaken by the generator. Co-ordination of generation with third-party inter-connected networks would be a matter for normal commercial contractual arrangements. 3.10 The Commission may, with the approval of the Minister, grant an exemption from the requirement to be licensed. Licences are not currently required for: small scale and own-use generation and low volume sales of electricity; and on-supply of electricity, as long as the on-supplier complies with certain conditions.
