System Operator market operation service provider
This requires maintaining a continuous (second-by-second) balance between electricity supply from power stations and demand from consumers. The System Operator achieves this by determining the optimal combination of generating stations and reserve providers for each half hour trading period, instructing generators when and how much electricity to generate, and managing any contingent events that cause the supply demand balance to be disrupted. System Operations staff in Transpower's control rooms undertake this work using sophisticated modelling and communications technologies.
In addition to its real-time dispatch and security management role, the System Operator also carries out investigations and planning to ensure that supply can meet demand and system security can be maintained during future trading periods. Examples of this are co-ordinating generator and transmission outages, facilitating commissioning of new generating plant and procuring ancillary services to support power system operation.
