There is only a single wind/hydro combination in the whole country that is truly complimentary and that is Trustpower's Mahinerangi wind farm and Waipori Hydro group. These two assets share the same 33Kv lines between Waipori No1 station and the switchyard at Waipori Falls. Until Mahinerangi stage 2 is completed it would be a nightmare to try and separate those two assets. In the rest of the country wind and hydro are competitive rather than complimentary despite what the theory says.
