A fundamental requirement of competitive and efficient electricity markets is access to reliable data and performance metrics.
This Electricity Market Information website (EMI) is the Electricity Authority's avenue for publishing data, market performance metrics, and analytical tools to facilitate effective decision-making within the New Zealand electricity industry.
Benmore Q4 baseload contracts continue to trade below the average spot price to-date during the quarter, indicating a market expectation that prices will remain well below $100 for the remainder of the contract period. This follows significant rainfall in November boosting storage in southern hydro lakes  . The implied spot price derived from currently traded baseload contracts is available in a public dashboard  .
November inflows returned national storage to above-average historical levels. Northward flow across the HVDC has increased. Contributing to the increase in national storage, Taupo has increased to above-average levels during the last month after lingering at below-average levels since September 2018. Each update to the 2020 ERCs is presented in a public dashboard on EMI. The official curves and more information on security of supply forecasting are available on the system operator's website.
The volume of off-market trades as a proportion of the total volume of New Zealand electricity futures traded on ASX has been increasing over time. This can be seen in the size of the orange and light blue bars, i.e. the exchange for physical and block trades, in the report of monthly trade volumes since 1 January 2016. Note 8 of the trade volumes report provides additional information about these trade types.
This report presents information on the distribution of final prices for a selected period of time. The report facilitates comparisons between regions (or nodes), and for any given region (or regions), it allows comparisons across the same time period. For example, Upper North Island prices in August over the last 10 years . Users can also select a 'difference node' to report on the distribution of the difference in the price between the selected node and the selected difference node. The figure below shows daily price distributions for network regions over the last three days. Any outliers are easily identified. Remember to check out the "All dashboard instances" button on the top right of any report to see what instances users have added to their dashboards.
October 2018 was a period of low inflows and reduced thermal fuel availability that resulted in sustained high prices. Several participants joined forces to lodge an Undesirable Trading Situation (UTS) claim in relation to the circumstances and information available to market participants at this time. Taupo inflows have been low since late September 2018, (74 per cent of average from 1 Oct 2018 to 15 Jan 2019) contributing to national controlled storage remaining below average. As 2019 gets underway, prices continue to remain stronger than in recent years.
