Quarterly Operating Report | Q3-23| December 2022
Quarterly Insights
Spot prices suppressed
Spot pricing over the period was generally low, with weekly average Benmore pricing averaging $38/MWh and Haywards averaging $44/MWh.
Inflows and Storage
National storage rose slightly in absolute terms across the quarter, however ended lower compared to the 10-year average - starting at 143% of the 10-year average and finishing at 116%. Manawa inflows were strong across the period, up 48 GWh (11%) on average. This was driven by very strong North Island inflows, partially offset by below-average South Island inflows. YTD Manawa inflows are 17% above average. Manawa storage increased to end the period at 133% of average.
Generation volumes
Total Q3-23 generation volumes were 481 GWh. This is 4% higher than the pcp due to North Island volumes being 35% higher than the pcp offset by South Island volumes 28% lower. YTD generation volumes are in line with the pcp in total, however this is made up of higher North Island volumes (27% higher), and lower South Island volumes (24% lower).
The selective use of stored water in the South Island (due to lower inflows and deliberate storage decisions) is the main driver for the Q3 GWAP/TWAP of 1.40 for the South Island.
C&I customer volumes
The recent volume reduction in C&I sales is principally due to not re-contracting a single, large, wholesale-priced customer. Over the recent 3-6 months we have renewed contracts with several large C&I customers despite competitive and volatile market conditions and continue to see positive opportunities for growth in the segment.
