Environment Minister Simon Corbell on Tuesday announced what he described as the "final piece" in his government's plan for 100 per cent renewable energy by 2020. 

The 91MW $200 million Crookwell 2 wind farm, to be built by Spanish-owned company Union Fenosa Wind Australia, has won the right to be paid feed-in tariff grants under the ACT’s reverse auction process. 

The project, due to be completed in September 2018, will build 28 turbines able to power 41,600 Canberra homes. 

Mr Corbell said the Crookwell farm would be paid $86.60/MWh for the energy it feeds into the grid, which he said was a record low for a NSW wind farm.

The other successful bidder in the ACT’s auction was the Hornsdale Wind Farm, north of Adelaide.

Mr Corbell said the two successful bids secured the final renewable energy needed to meet the ACT’s 100 per cent target.

"These two wind farms will lift our renewable energy percentage to 100 per cent by 2020 and secure the achievement of our emission reduction goals in that year."

The NSW government said the $200 million Crookwell wind farm would directly support 80 construction jobs and 14 ongoing operational jobs. 

Union Fenose has also committed to a "community enhancement fund" of $2500 per turbine, and established a shared benefits scheme for those living nearby, according to NSW Resources and Energy deputy secretary Kylie Hargreaves.

Ms Hargreaves said nearby farmers will be able to continue working the land surrounding the turbines.

"NSW offers a number of sites which offer a combination of high average wind speeds, consistent winds, and smooth landscapes," Ms Hargreaves said.

"The construction of this wind farm will contribute to the financial security of the people of the Upper Lachlan, Crookwell, and Goulburn, and demonstrate the potential of renewable energy to transform our regional communities."
