The go ahead's been given to a proposal that'll see a huge amount of energy pumped into the national grid.
Planning commissioners have given resource consent for a controversial wind farm in the Wairarapa region, covering 27 existing farms between Masterton and Pahiatua.
Genesis Energy's Public Affairs manager, Richard Gordon says there'll be around 260 turbines when it's fully completed.
"They could have an annual output of around 3000 gigawatt hours which is a huge amount of electricity, it's almost as much as the older part of Huntly power station produces."
However, Mr Gordon says the market's well developed at the moment so until conditions change they won't start building.
