ASX Electricity Futures

The Australian Securities Exchange (ASX) listed Base Load Electricity Futures, Strip Futures and Calendar year

Strip Options for two grid reference points (Otahuhu and Benmore) in the New Zealand electricity market in July

2009. The ASX New Zealand Electricity Futures contracts are cash settled using the arithmetic average of half-

hourly prices at the designated node over the period of a calendar quarter.

The two charts below display the price movements of the front quarter futures contract during the current quarter and

for the four quarters prior to the current quarter. Also shown is the volume of contracts traded, the relevant spot price

and the spot average price over the quarter during the time when each contract was the front quarter contract.

The chart to the right shows the most recent

transactions for all currently traded futures

contracts at both the

BEN & OTA nodes.

For comparison these

prices are mapped against the prices for

the same contracts four

weeks prior to the current Market Review.
