Wind turbine towers and nacelles are in place at Turitea awaiting the rotor hubs and blades. When Mercury’s $465m, 60-turbine Turitea wind farm is complete, that will rise to half of the nation’s wind power. It’s a huge contribution but, even so, wind currently provides less than 6 per cent of New Zealand’s electricity. In order to reach the Government’s target of 100 per cent renewable energy by 2030, wind generation is going to have to increase 10-fold. The Tararua skyline, the windiest, richest wind resource in New Zealand, if not anywhere in the world, according to Mercury’s generation development manager Dennis Radich, has pretty much run out of capacity.
