Wholesale reports

This report lists network supply points (NSPs) that are used in the reconciliation process and their details. Coordinates are provided along with mappings to various region types.

This report presents trading period demand values (MW) or demand weighted prices ($/MWh) for the selected date range, ranked in descending order. Values are sourced from our reconciled volumes dataset (GR010), which is updated monthly, and WITS final pricing.

This report presents the impact on the cash flow of firms participating in the wholesale market under two simulated stress scenarios.

Unaccounted for electricity by network. Based on information, (GR-280), available from the reconciliation manager, at https://www.electricityreconciliation.co.nz/public_files

This report shows wholesale dispatch reserve prices for the electricity spot market.

This report shows wholesale dispatch energy prices for the electricity spot market.

This data report enables certain data to be downloaded for a single node or point of connection. Simply select a node and a date range, and the data will be available for download as a CSV file. At present the only data available is wholesale energy prices.

The results for three measures of financial stress faced by firms participating in the wholesale market under two simulated stress scenarios are summarised in this report.

A simple measure of vertical integration within firms operating in the wholesale electricity market has been constructed using reconciled sales and purchases and can be tracked through time.

This report provides an alternative presentation of the stress testing summary report. Rather than show the distribution of all respondents' scores, it shows the number or percentage of respondents falling into groups with similar scores.

This report explores the sensitivity of nodal prices to changes in load, or demand. Load is both incrementally increased and decreased in a series of experiments based on the price response schedule for each real-time trading period and the subsequent seven future trading periods. For each experiment, the resulting nodal prices are reported.

This report shows planned or scheduled electricity generation outages by generation type, participant, and island. Analysis of the generation capacity available to meet demand will be supported by the use of this report.

This report shows historical location factors for a region relative to a selected basis node. A location factor is simply the ratio energy prices at two different locations. They provide useful information when seeking to manage locational price risk and can be used to adjust prices from one node to what it might be at another node or in another region.

This report splits offers bid into the spot market for reserves (FIR and SIR) in to price bands and plots the cleared quantity against these. Users are able to adjust the bands in the offer stacks and investigate the reserves offered in each island.

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 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 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.

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 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 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 shows prices for reserves (FIR and SIR) in the electricity spot market 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 electricity generation injected into the grid. Users can drill down from a national level to individual nodes and investigate trends through time.

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 wholesale energy prices for the electricity spot market. Parameters allow selection of weighting type, time scale, and regional averages.
