The Thunderbolt Energy Hub will connect a massive 380 megawatt wind farm and 120 megawatt solar farm to a 400 megawatt battery.

The development application is expected to be submitted in 2021.

Project proponent Neoen promised they will adopt a "no surprises" approach for the proposed scheme.

The company invited community members to a "community drop-in" session next Wednesday.

Project manager Joanna Murphy said Neoen was eager to introduce the community to what she said was an exciting clean energy project.

"Community drop-in sessions are a great way to keep the community informed; you can meet members of the project team, ask lots of questions and take an information booklet home for friends and family," she said.

Neoen plans to build and run the project - as opposed to developing it to be sold.

The $1.01bn project is expected to create over 600 jobs during construction, a process set to last between two and three years.

It will be constructed on private lands at a site about 40 kilometres north-east of Tamworth and 40 kilometres south-west of Armidale. It will continue to employ between 20 and 30 people once switched on.

The project is set to fund a community benefit sharing fund worth $200,000 per year based on the current project size. The company is seeking community input on the fund.

The community drop in session will be held on Wednesday September 16 from 3pm to 7pm at The Alternate Root cafe in Uralla.
