This report shows wholesale energy prices for the electricity spot market. Parameters allow selection of weighting type, time scale, and regional averages.
This report splits offers bid into the spot market for energy in to price bands and plots the cleared quantity against these. Users are able to adjust the bands in the offer stacks and drill down to individual nodes in the wholesale market.
This report shows electricity generation injected into the grid. Users can drill down from a national level to individual nodes and investigate trends through time.
This report shows the electricity demand from the grid. Users can drill down from a national level to individual nodes and investigate trends through time.
This report shows differences average regional wholesale energy prices for a day, month, quarter or year on a map. Alternatively, the report can show the difference in regional prices relative to a selected difference node.
This report is a companion to the residential consumption trends report. The report presents the remainder of reconciled demand on a monthly basis and allows the user to differentiate business demand by connection type, either network connected or directly connected to the grid. Business demand can be shown as a proportion of regional or national demand with options to include or exclude the NZ Aluminium Smelter (NZAS).
This report summarises the distribution of historical wholesale energy prices within a day, month, quarter or year. Alternatively, the report can summarise the difference in prices for the selected regions (or nodes) relative to the prices at a selected difference node. The report provides powerful options for comparing prices both between regions and across time.
This report shows trends in the proportion of a company's generation or demand that is exposed to the physical wholesale market. The report ignores any derivative or hedge positions held by the parent companies. A measure above zero represents a long position on physical generation while a measure below zero represents a short position on physical generation.
This report shows the flow (MW) and the energy transferred (MWh) across the HVDC link that connects Benmore in the South Island to Haywards in the North Island. For longer time scales, the net transfer or peak flow can be shown.
This report calculates historical location factors for a region or node relative to a selected basis node. A location factor is simply the ratio energy prices at two different locations. They are commonly used to adjust prices from one node to what it might be at another node or in another region.
