Turbines would be constructed at Bowmans Creek, Goorangoola, Greenlands, Hebden, McCullys Gap, Muscle Creek and Rouchel Brook.
The company has been researching the project since 2017. It's monitoring found the area, which primarily consists of beef cattle grazing land, was among the most suitable locations in the region for a wind farm.
"Prevailing winds are from the south-east in summer, north-west in winter and from both directions in spring and autumn. Wind speeds typically increase throughout the day with a peak in the evening period followed by a low in the early morning," an environmental impact statement for the project, which is currently on public exhibition, says.
It is estimated that the project would create up to 156 full time equivalent jobs during its 18-month construction period and 15 full time equivalent jobs over its operational life.
Epuron says the project is consistent with the aims of the Hunter Renewable Energy Zone, which was created late last year as part of the State Government's Electricity Infrastructure Roadmap.
"The Hunter Region produces approximately 44 per cent of the power generated in NSW. With the closure of Liddell and Bayswater power stations, it is necessary to transform the regional energy sector," the environmental impact statement says.
"The Hunter Region has the solar, wind and geothermal resources required for the development of large-scale renewable energy projects. As such, the Hunter Region has the potential to become a major renewable energy hub."
