Media Statement from Hon Trevor Mallard, Minister of Energy

Energy Minister Trevor Mallard says the potential for wind-generated electricity in New Zealand appears to be greater than previously thought.
"Wind energy could supply around 35 per cent of New Zealand's future peak electricity demand, according to a study I have released today," Trevor Mallard said.
The study, commissioned by the Ministry of Economic Development (MED) and the Energy Efficiency and Conservation Authority (EECA) considers how much wind-generated electricity could technically be integrated into the New Zealand energy supply system.
"This report shows the potential is very high, and rapid advances in technology are making it possible to tap more of that potential. While it is not intended to be a conclusive study it helps us to look ahead and consider a future electricity supply system with a different mix of generation," Trevor Mallard said.
"New wind generation proposals are being announced at an accelerating rate. Currently, wind accounts for 2.5 per cent of peak electricity generation, but is the fastest growing sector of the generation market.
"There are some caveats around this study as it does not take into account environmental and economic factors.
"It is also important to note that there are challenges in integrating wind power that are yet to be resolved. But with the advent of new tools such as wind forecasting software, a more diverse distribution of wind farms around the country and turbine technology which has similar characteristics to that of existing generation, the future is looking very positive for wind power.
"We are not expecting the potential to be realised overnight, but wind generation could play a significant part in meeting on-going growth in electricity demand. It will be part of a diverse energy mix to improve security of supply, contribute to the National Energy Efficiency and Conservation Strategy renewable energy target and reduce carbon dioxide emissions under our international Kyoto Protocol obligations," Trevor Mallard said.
"New Zealand is in a unique position to utilise wind energy, both geographically, and because of synergies with our existing hydro generation. The fluctuating nature of wind works well with hydro generation, which can be switched on and off at short notice, and allows water to be stored when the wind is blowing."
The report recommends further work including developing data for more detailed and accurate analysis, developing appropriate standards for wind farms connecting to the grid, and methods of forecasting output from wind farms.
"This report is an important first step in learning more about the potential of wind. Further work is now planned between MED, EECA and the Electricity Commission," Trevor Mallard said.
