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.
At the end of November 2020, small and medium retailers collectively served 15.6 per cent of ICPs in the market, overtaking Mercury who supplies 15.5 per cent. In aggregate, small and medium retailers now supply the third-largest number of consumer connections with only Genesis and Contact supplying more. Nova Energy, Pulse Energy Alliance, Electric Kiwi, Vocus, and Flick Electric make up the majority of this group. Over the last 12 months, individual company growth in ICPs   is led by Electric Kiwi, Meridian, and Nova. Percentage growth over 12 months   highlights the newer entrants and the exits in 2020.
Long-dated forward price curves dropped 24% at both Benmore and Otahuhu on Tiwai aluminum smelter exit announcements. 263 long-dated contracts were traded on 9 July, mostly maturing in 2021 and 2022. Tiwai load accounts for approximately 13 percent of national demand. NZAS has terminated its power supply contract which will end in August 2021.
2020 was an interesting year in the electricity market with much uncertainty around how demand in 2021 would respond to a recession and potential industrial plant closures. By the time 2020 came to a close, open interest in 2021 calendar year baseload futures contracts had reached 5,140 GWh. This was the highest open interest for any calendar year period since the exchange-traded futures market was established in 2009. The previous high was for the 2019 calendar year when open interest peaked at 3,380 GWh early in that year. Open interest for 2021 baseload products represents a 52 percent increase over the 2019 equivalent and accounts for 25 percent of the annual electricity consumption in New Zealand. Compare the rate of accumulation and the level attained with other calendar years in the public dashboard.
