The electricity market this month

Mike Capel, Portfolio Trader, Trading and Operations

Average NEM settlements, outside SA, increased in August driven by unplanned baseload outages and low wind generation in the latter half of the month. High wind generation in SA and the limitation of interconnector export to VIC drove the lower SA spot settlement. In July there were price spikes that contributed $24.73 to the $105.77 average. In August there were no high price events, which accounts for most of the drop in average price July to August.

Gas market update

Louise Colbran, Portfolio Trader, Trading and Operations

The last two weeks of August reflected true winter conditions. Temperatures plunged across the south east of Australia driving a final burst of market demands. Prices were much more elevated across this period, though this isn’t reflected in average monthly pool prices as markets were supressed at the start of the month.

To put the last fortnight into context, underground storage went through over a quarter of its remaining inventory with almost 4PJ being utilised since mid-August. The cooler weather combined with coal fired baseload outages and lower wind generation pushed up gas fired power generation requirements.
