Genex Executive Director Simon Kidston told the Forbes Advocate the 50MW solar array would see more than half a million flat-plate panels installed across a 200 hectare rectangular block of land.

The thousands of tracking panels will follow the sun from east to west each day.

Genex already owns and operates a similar solar power plant in Queensland, west of Townsville, with big renewable energy plans in the pipeline for that location.

When they looked to diversify into NSW, the Jemalong property adjacent to the existing Vast Solar plant was flagged as an ideal location.

Development consent has been granted and the company last week released a statement to the stock exchange outlining that the plan had been financed.

"Renewable energy is our business and where you are is one of the best solar resources, the ground is consistent and there is a high voltage transmission network," Mr Kidston said.

"What we are building at Jemalong is almost identical to what we built in north Queensland two years ago."

That array is pictured above.

Genex is a power generation development company listed on the Australian Stock Exchange.

Construction company Beon has been appointed the lead contractor and Mr Kidston said they would use as many local contractors as possible.

During construction, he would anticipate a workforce of about 150 people - again with a focus on using as many local tradespeople as possible.

Work on the turn-off from the Lachlan Valley Way is likely to begin before Christmas, with work to start on site in the new year.

Genex expects it to be supplying power to the electricity network by the end of 2020.

The 50MW plant is expected to produce 128,700MWhr of electricity per year, enough to power more than 23,000 homes with renewable energy.

It will offset 106,500 tonnes of carbon dioxide a year, the equivalent of taking 29,000 cars off the road.
