Pricing market operation service provider

The Pricing Manager is the market operation service provider responsible for calculating and publishing the spot prices at which electricity market transactions are settled. Prices are derived using sophisticated models which calculate nodal prices for each trading period based on generator offer prices and quantities, demand, and system conditions. NZX is contracted as Pricing Manager.

In the wholesale electricity market, changes in demand and supply over the course of a day result in different prices for electricity during each half-hour trading period. Prices also vary by location, reflecting the costs (electrical losses and transmission constraints) of getting electricity from source (generator) to destination (consumers).
