NZX To Launch New Zealand Electricity Price Indices

16/12/09

NZX will launch a set of electricity price indices, providing electricity market participants a mechanism to track price movements in the wholesale electricity market.

The methodology and 5 year back calculation will be made available on 11 January 2010.

There will be two NZX electricity price indices, each calculated for four regions:

NZX Real Time Electricity Price Index (NZX REPI)

Upper North Island
Lower North Island
South Island
New Zealand

NZX Electricity Price Index (NZX EPI)

Upper North Island
Lower North Island
South Island
New Zealand

The NZX Real Time Electricity Price Index (NZX REPI) will be calculated from indicative ‘five-minute prices’ and distributed in near real time once five minute prices are published for each 30 minute trading period. The NZX Electricity Price Index (NZX EPI) will be calculated daily from final prices which are published daily by NZX.

Electricity prices are published through the Wholesale Information and Trading System (WITS) maintained and operated by NZX.

Following this early January release NZX will be talking with industry stakeholders about the indices, their calculation and use in measuring and managing price risk.
