The company behind the plan, Rio Indygen, has revealed there will be up to 20 jobs while the farm is built and two or three will continue after the construction phase has finished.

A 50 hectare site close to the historic village of Vacy has been flagged for the project and Rio Indygen has secured an 'option to lease' agreement with the landowner.

But it is not know how much power the 25 megawatt farm will generate.

Project manager Andy Barrow would not answer that question, saying it was "commercially sensitive information" and "not publicly available".

He would not say why the company had set its sights on Vacy or reveal how long the project had been in the pipeline, sighting the same reasons.

"The project will have a positive effect on the environment, providing CO2 emissions free electricity to the grid," he said,

"The site itself will benefit from an improved ecosystem.

"The wider economic impact of the building of the solar farm will be felt during the 6 month construction phase.

"This will include, spending at hotels, shops, restaurants, equipment, plant and material suppliers."

Mr Barrow revealed the company had considered sites at Martins Creek before it started looking at Vacy.

He said there were not any suitable land parcels in Martins Creek.

Power from the site would be sent back to the substation at Martins Creek.

The company has proposed that the farm would run for 30 years and it would take six months to set it up.

Rio Indygen is creating a 10 megawatt solar farm four kilometres south of Moruya, on the far south coast, according to its website.

It will use a 25 hectare site to generate 18000 megawatt hours which would power 3000 homes.

Mr Barrow would not give any details about other solar farms the company was pursuing, saying it was "commercially sensitive information".
