The 31-turbine Biala Wind Farm will power 46,000 typical homes when completed.

The Chinese-owned Goldwind Australia will manufacture, supply and install the turbines; Consolidated Power Projects Australia will deliver the high-voltage electrical infrastructure; and CATCON for civil works.

"We are confident they will deliver a first-class project. They have all been chosen for their vast experience and successful track record in Australia," deputy general manager Derek Powell said.

It is expected construction of the wind farm, around 45 minutes from Goulburn in the Upper Lachlan Shire, will begin in July this year and will take around 18 months.

Earlier this month, the proponent BJCE Australia offered neighbour agreements to 19 eligible landholders.

At the time, deputy general manager, Derek Powell said neighbour agreements seek to offset the impact of the wind farm on its closest neighbours.

Since, concerned residents say they're waiting on further information regarding the wind farm before they'll sign on with the proponent.

David Bugeja, who operates a poultry farm adjacent to the wind farm, is concerned about the noise - amplitude modulation or rumbling from a wind turbine; construction/decommissioning - and the potential ill-effects on his business.

He is requesting a sound impact statement.

Ken and Jennifer Hewitt say that after repeated attempts to tour a dwelling on their property, representatives from former proponent Newtricity and BJCE Australia are yet to visit the site.

The Hewitts are certain the unoccupied dwelling warrants further investigation and an impact study.

Divalls Earthmoving and Bulk Haulage commenced with road upgrades to Range Road on May 21, between the intersections of Kialla and Grabben Gullen Roads.

The project will take four months and employs 20 people.

"We would estimate that 10 million dollars has been spent in surrounding regional roads due to the development of renewable energy projects," Andy Divall said.

In the Southern Tablelands, BJCE Australia also owns the 73-turbine Gullen Range Wind Farm and the 10-megawatt Gullen Solar Farm.
