New Zealand Experiments With Real-Time Electricity Pricing

LCG, October 15, 2002-M-co, New Zealand's electricity market operator, has begun operating a real-time wholesale electricity pricing system.

Normally, New Zealand's wholesale electricity prices are calculated every 30 minutes, but M-co will now have the prices reported every 5 minutes. This publishing-per-5 minutes trial will last three months and will not affect market settlement as yet.

M-co's intention is to optimize the market; the company feels that the shorter time may have a positive effect on the calculation of settlement prices.

M-co also operates the retail electricity market of South Wales, the green energy market of Australia, and the wholesale electricity market of Singapore, in addition to working with developing markets in Africa.
